Owners Thread Sony Bravia "r" Series (sxrd) 60"-70" 1080p

Recommended Posts

Pietro, it definitely looks like you've got some convergence issues there. Luckily it can be fixed via the service menu. You can move the RGBs in 1 pixel increments.

I think it was Dr Smith who has had convergence altered. Have any other owners had this adjusted? It is disappointing that the set can have problems.....so many early reviewers said SXRDs didn't have any such issues.

Interesting to get a review from someone who has had the Toshi 72" DLP and based on this I won't be moving to the SXRD if I can get the diagonal line issue fixed - I'm very surprised Castel told you they couldn't guarantee a fix for this fault.

They don't seem to have a fix. Even new light-engines from Singapore couldn't be guaranteed to be fault free they said. Although they said 99% of people don't notice. I can't believe that.

Pietro,

thanks, oh dear, the fault is so obvious I can't believe what Castel told you. I will contact them next week.

You commented the SXRD was noisy - how does it compare to the Toshi which was my only other criticism of it.

It was.

Looking at the convergence image from your earlier post there does appear to be a problem with convergence, however a better indication of any convergence error will be obtained by displaying a PC desktop at the SXRD's native resolution (1920x1080) via DVI from PC to HDMI on the SXRD.

This display offers 1:1 pixel mapping at native resolution, so an image of text from a web page at native should reveal far more on any convergence error than your above image.

I only had a one pixel convergence error with one colour, but yours may be more pronounced given that it can be seen on the picture menu and that you notice a problem from a normal viewing distance. I had a service tech correct mine via the service menu under the Sony warranty.

I find the fan to be very quiet on the normal setting, but if the cooling mode is set to high the fan operates at a higher speed and is somewhat noisier.

It's very difficult photographing the convergence malalignment with a consumer level digital camera. The trouble is that a consumer level still camera will only focus with a sweet spot in an isolated region. Anyway, here is a picture taken of my 60" set displaying a convergence test pattern to give a very broad idea: http://www.dtvforum.info/index.php?act=Att...ost&id=2372

The picture is not very accurate. Inspection with the naked eye reveals the following patterns:-

Vertically (a one pixel wide vertical line):

*************************************************

*************************************************

*************************************************

*************************************************

*************************************************

*************************************************

*************************************************

*************************************************

*************************************************

*************************************************

*************************************************

*************************************************

It will be noticed that the vertical alignment is pretty accurate.

Horizontally (a one pixel high horizontal line):

******************************

******************************

******************************

******************************

******************************

******************************

******************************

******************************

******************************

******************************

******************************

******************************

******************************

******************************

******************************

******************************

The horizontal alignment is marred by the fact that red consists of two lines of pixels, the upper line slightly fainter in colour. (This upper line is not visible in the photo, but is quite visible to the naked eye). This may be an anomaly in the video processing; or perhaps it was set that way at the factory to attempt to average out the misalignment of the blue (in a low position) and green (in a high position).

This is something I may have to ask Sony to check.

I would have thought a better compromise would have been to drop the line of green pixels by one pixel position; and to dispense with the upper line of red pixels.

Position of centre speaker

I have the SXRD mounted on a coffee table, and a centre speaker sits on the 'magazine shelf' of the coffee table, as per this picture. The screen is displaying a mallard and ducklings, superimposed on an 'outer geometry' test pattern.

The sound seems fine*. However I'll try some critical listening to material with centre channel content, before posting comments in the Home Theatre sub-forum.

* P.S. Until playing a DVD with strong centre channel content! The centre speaker will need to be raised.

Thanks mate. At least I'm getting 1:1 pixel mapping on this set, albeit with overscan. :blink:

Hi dlenaid. People tell me I'm very critical of picture quality, but I have found the performance of my 60" SXRD quite good on all standard definition channels except SBS.

I wonder if you could advise:

*Which standard definition channels have you been watching?

*What viewing distance are you using to watch them?

*How do you rate the picture quality you are getting from your ordinary DVDs?

SBS high definition is not that much better than their standard definition. I understand SBS's budget is limited and they do not invest a great deal in their transmitting equipment. They even seem to broadcast at low signal strength (at least in Brisbane).

I've compared the picture from my Topfield standard definition PVR through component, with the SXRD's internal tuner, and the SXRDs is a little better; but you have the 70" model so there would be no internal tuner.

I note that you were using a Sony HD PVR, and someone suggested an LG as it supposedly has better picture quality.

It does surprise me you are finding the SD transmissions so poor, unless you mainly watch SBS.

Since I wrote the above, the set has been in use for a further 7 hours or so, doubling as a computer monitor in addition to its function as a TV.

I am finding the colour even better this evening. It is beginning to attain the uncanny realism I saw in the showroom. Ultra High Pressure lamps are supposed to vary with age, losing brightness, but I am surprised at how much variation I have noticed so far in the colour. My partner has also noticed the improvement. This is a most interesting phenomenon. When these sets are reviewed, I wonder whether the manufacturer supplies a set with a lamp that has been 'run in'.

MLXXX we watch much TV on all channels. Telecast quality do not think is best on any channels. It is the rubbish on the telecast that is hard not to see. For high definition channels channel 7, channel 2 and for SBS we do not see much improve. For high definition channels 9 and channel 10 there is sometimes some true high definition but if you look carefull there is rubbish there on screen. DVD quality is good not like Blu-ray but not too much rubbish like with TV telecast.

We have done many distances from the television. From 2 meters for Blu-ray and high definition TV telecast and 3.5 meters far for standard television telecast. We now have sofa at 3.5 meters which too far to see blu-ray properly but with TV we see less rubbish.

I have compared in Harvey Norman this week the Sony HDPVR and LG HDPVR. There is little difference. The rubbish is there with both equipment, maybe little less to see with the LG HDPVR.

When went to buy the TV in store we liked Blu-ray picture, we did not see before buying on TV telecast. Since buying the TV we are noticing poor TV telecast picture. Maybe we are pickie. Maybe one day TV will improve like Blu-ray. Not all blu-ray is best but TV telecast has much rubbish.

Pietro,

You commented the SXRD was noisy - how does it compare to the Toshi which was my only other criticism of it.

Ironically, the fan noise from the Sony is louder than the colour wheel noise of the Tosh, at this stage. I'm hoping that the Sony will get quieter as it runs in, though I am about 100 hours up now.

Thanks for the comments re convergence. I'm still thinking that as the picture is so good now especially on HD, I may well leave it alone.

The other thought is if I can get someone to calibrate it, and they have the service manual, I could get the convergence done then. I really don't think a country service agent is going to have any idea and might make it worse.

I think OZHTfan is on hols.....I know his was calibrated, though from what I remember it seems to have been done without the service manual.

I am getting a Tosh HD-E1, can't wait to see the HD-DVDs on this set.

Jeez, I'm finding that in a room where I can hear a pin drop, I can't hear the sound of the SXRD fan. The only time I can hear it is if I poke my head around the back of the TV. Maybe for once in my life I got a good sample because I'm not having any of the issues that others are posting about.

Anyway, here is a picture taken of my 60" set displaying a convergence test pattern to give a very broad idea: http://www.dtvforum.info/index.php?act=Att...ost&id=2372

The above test pattern looks like one from http://www.idk-tech.com/products/techpcvg.html which I have also viewed on my unit.

For testing convergence and doing pixel counts on geometry, I used the crosshatch pattern from the test pattern software I downloaded from the above link. It is possible to adjust both the width of the lines and the size of the black squares between the lines to any pixel width.

With the default settings for the crosshatch (spacing 1, width 32), any convergence error at a per pixel level shows up very well. Any variation in convergence across the screen can also be seen. The one pixel convergence error on my unit manifested itself as white horizontal lines one pixel wide showing up as two seperate colours (neither white), each one pixel wide when viewed at close range. This test pattern also made it very easy for the service tech to apply the appropriate adjustment through the service menu (in my case a vertical adjustment of one colour by one pixel).

Viewing black text on a white background at native (for example: forum web pages) will also reveal any convergence error at the per pixel level.

With regard to pixel count on geometry, I used the crosshatch pattern with the whte lines one pixel wide and the black squares inbetween at 2x2 pixels (spacing 1, width 3). Spacing 1 and width 2 is the most ideal setting for pixel count if convergence is good to start off with.

For comparison puropses I will do a revised pixel count on geometry later today exactly as you have done in your earlier post here using the above crosshatch pattern.

Me too, for all practical purposes the normal cooling fan mode is silent at 2meters viewing distance.

I sit at 4m and can hear the fan. (Is there only one?) I do live in the country though and there is virtually no background noise. Also I wonder whether the fan noise could be resonating in the wooden shelf of the stand? Yet another factor is the plastic casing of the rear part of the unit. Give that a tap and hear there is no deadening in it at all.

I suppose with the convergence issue, the most important question is does it make any real-world difference to the picture if it's a bit out? I was watching Food Safari India (SBS) last night and the colours were absolutely extraordinary.

Have you checked the cooling mode ?

The fan may be on the high speed setting.

But mine definitely has an issue with convergence. See Could other owners please have a look and see how their sets compare. When watching the cricket (I sit at 4m) I can often see a red edge on the right of the white outfit, and a green edge on the left. Maybe because I have had 3 CRT RPTVs before I am very prone to noticing any convergence problems. I believe that with any RPTV with the 3 colours separated there will always be a problem to some degree. That was one area where the DLP was perfect.

I suppose with the convergence issue, the most important question is does it make any real-world difference to the picture if it's a bit out? I was watching Food Safari India (SBS) last night and the colours were absolutely extraordinary.

If there is an issue that bothers you when watching the cricket or anything else at a normal viewing distance, then to me that consitutes a real world difference to the picture.

EDIT:

With a one pixel error on mine, I could not notice it when viewing video content. If you have a PC (as described in post 25), the test patterns used by myself and MLXXX could yield very interesting results on your unit.

The fan is definitely on low-speed.

The cricket is the only time I have noticed any convergence problems from my viewing seat. Ch9's (WIN's) picture is so full of artifacts that it seems just another aspect of their crappy transmission.

I think the problem might be I'm so sick of all the things that happened with the DLP I really don't want to go through it all again with Sony. Hence "put up with it" and accept that no TV is perfect. I think I can live with the issues, at this stage anyway

My situation too! In fact if I had not known it had a fan, and therefore expressly listened for it, I would possibly still not know it had a fan! And I've had no mysterious shut-downs, touch wood.

Pietro mentions possible resonance of the cabinet. In my own case, the coffee table that supports the TV is on a mat. Also, behind the TV there is a medium weight curtain.

...

To me the glory of the SXRD is the colours…….rich and deep.

Yes! Reds and yellows are vibrant. Greens seem to have a wide range, noticeable on foliage. Overall, for my vision, the colours are closer to reality than with slim panel LCDs, and plasmas.
... For high definition channels channel 7, channel 2 and for SBS we do not see much improve. For high definition channels 9 and channel 10 there is sometimes some true high definition but if you look carefull there is rubbish there on screen. DVD quality is good not like Blu-ray but not too much rubbish like with TV telecast.

It's disappointing Channel 7 HD only manages 576p. It is a major telecaster and yet all it is offering is a standard definition number of lines, with progressive scanning. SBS HD's 576p seems even worse, probably due to a low bit-rate. I find ABC HD's 720p pretty good. The high resolution of the SXRD does reveal the 'swirls' of MPEG encoding. Ch 9 HD and Ch 10 HD can be quite impressive.

... But mine definitely has an issue with convergence. See Could other owners please have a look and see how their sets compare. When watching the cricket (I sit at 4m) I can often see a red edge on the right of the white outfit, and a green edge on the left. Maybe because I have had 3 CRT RPTVs before I am very prone to noticing any convergence problems. I believe that with any RPTV with the 3 colours separated there will always be a problem to some degree. That was one area where the DLP was perfect.

At a viewing distance of 2.2m, we notice tinges occasionally, to the left or the right. Only once so far has it been really marked: during the cricket, a player's hair had a noticeable green tinge to the right, against a bright background. There could be factors coming into play other than convergence misalignment:

* on our SXRD, horizontally there appear to be some variations in colour saturation at transitions, even with video 'enhancements' turned off, when viewing a PC generated test pattern.

* MPEG encoding favours intensity detail over colour detail. The MPEG decoder has to make approximations where colour is concerned. A high resolution CRT could be used for comparison.

But really, for us, the tinges are minor.

I think a heavy curtain could definitely make a difference. I was also wondering about some sound-deadening material on the sloping back of the cabinet. Also the thought of putting something between the base and the stand to see if that makes a difference.

I have to agree, even late at night in a rural area I found the fan only really audible with my head behind the set.

At 3 meters viewing distance is was basically silent and much less noticeable then the sound of a fridge running 8 meters away.

I cant think of anything with fan cooling that is quieter then the 60” SXRD that I heard in a domestic environment.

Petro,

The sound of the fan could be getting amplified by the environment behind the set.

Maybe some acoustic tiles on the wall would help.

There is a sticky thread about reducing Plasma buzz with sound treatment.

The fix is an electronic shift in the timing, in multiples of one pixel; not a physical adjustment to the optics.

In a worst case scenario, after electronic adjustment, the pixels could remain misaligned by 0.5 pixels [assuming the same misconvergence across the whole of the screen - otherwise the maximum misalignment could be worse than 0.5 pixels].

I will be interested to find out whether there really is an adjustment to cause an adjacent pixel to be brought into play. On my set, red horizontally is showing as two lines of pixels, as per my post #26 above.
