Magic Pvr Arrived Today

2,065 posts in this topic

Intermittent problems continue with the MAGIC tuner. I'm getting "no Signal - check the aerial" when the fault is obviously in the Magic.

I took the hood off and see the tuner module is part 601B10A23-01-1021-1011657.

So I've contacted Pixel in Hong Kong to see if they can supply me with this part. It is soldered into the motherboard so will be a bit of a pain to remove and replace but is obviously do-able if Pixel can help.

If they cannot, does anyone know where there might be parts in Australia? Obviously that tuner module is unique to Australia because we have a different digital protocol to the rest of the world. And this is a time when that difference is a real PIA.

In this throw away society the usual "cure" is to replace all of the motherboard so it will be interesting to see if I can locate that part somewhere. If Pixel cannot supply it I hope they can direct me to a source.

Hi John.

Just wondering if you've checked whether the power supply is still putting out 12 volts. Or have maybe tried the power supply from your other Magic on it.

The reason I mention this is a couple of weeks ago I checked over my mum's old Digicrystal because it was suffering from poor signal strength. It was especially bad on SBS even though it is normally one of the better performing stations.

Thought it was her antenna to start with but a couple of old set top boxes I plugged into it and her telly worked fine.

Opened up the Digicrystal and found a bulging capacitor in the power supply. Fitted a new one and the signal strength is spot on again and the box is once again working like a new one.

Thanks for that tip - makes sense. I'll check that out now.

LATER EDIT: No luck. I cannot see how to easily open up the MAGIC PS. I tried out another power pack but it obviouslt lacked the power. I have a massive linear PS here but it is only 6V.

Looks like I'll be shopping at Jaycar for a 12V 4A supply - are these figures correct?

Very similar to the one in the link below, just need to check plug size: 5.5 x 2.1mm at Jaycar.

That is certainly the best option around - well done. Worth us all buying as a spare at that price. That power pack is the weakest link although I'm not so sure that is the problem here.

We are currently experiencing very wet and sometimes very windy conditions and these are playing havoc with reception via the different aerial installed last year. I suspect the wet trees are screening the signal and the wind is twisting the aerial off focus. At times sensitivity is down to 54% and quality, although generally in the 80's or above, can dip to the 60's so even the best tuner would struggle.Viewing via the MAGIC was pretty bad last night so we had to use the satellite PVRs. The Ultraplus, which is pointed at the Optus D satellite for ABC & SBS does have a skip function but the VAST Humax, needed for commercial broadcasts, does not. And of course it is those commercial station broadcasts where the MAGIC shines.

The (much more expensive) alternatives I found are:

The Dealextreme one looks good value and at that price it is worth a punt. It looks the same or very similar to the PS that came with my WD Mybook external drive.

Found this one on E-Bay bit more expensive but comes with the 5.5x2.1mm plug. http://www.ebay.com....r-/400396174956

Good find and only a few dollars more than the other one. The plug is no problem here as I have plugs I can solder in, something not difficult but good to avoid if possible. However I've already ordered the $USD9 one and was able to pay by CC without messing around with PayPal (requires shifting dollars around accounts to cover it).

Bottom line is we have found good sources for power supplies. And, as you have said before, having an external power supply in a big plus as replacement is relatively simple, and is turning out to be inexpensive.

All this said, I'm mystified why Pixel are no longer selling the MAGIC here. Maybe they got their fingers burned too much with a warehouse full of the original Freeview release which they had to dump, presumably at a loss. With HD PVRs selling at not much more than $300 (remember when they cost over $1000?) there may be little incentive to remain in this Australian market with its unique video protocols.

The tuner should be MxL5007T.

Have you been able to find out whether the reception issue is specific to one tuner, or both tuners? This is quite important.

Not sure I understand what you mean. I only have one MAGIC here now (sold the other) if it is that. But earlier, other units here, using the same aerial connection, were working fine when the MAGIC was proclaiming no aerial signal.

However as posted above, reception did deteriorate everywhere last night but the MAGIC still hung in with some pixelation and did not proclaim the aerial connection was faulty. About the only difference has been to quirt some electrical contact cleaner around the aerial connector so maybe there was a bad connection problem before. I also squirted some around the tuner module inside when the hood was off.

All this has taken me by surprise as the MAGIC had always been regarded as ok for tuner sensitivity with far worse problems in the kitchen where we had a SONY STB feeding the Regal TV (with a very bad internal tuner). The SONY STB broke down and has been replaced with a DIGITEL STB, purchased as a result of a good tuner sensitivity rating from CHOICE. Looks like they could be right as the DIGITEL STB hangs in better than the MAGIC has lately.

As an aside, I followed CHOICE's recommendation a few years ago and purchased two REGAL TVs. Their tuner sensitivity is woeful and so I gave CHOICE a blast about not testing for it and recommending such cruddy products. Maybe they took notice because sensitivity is now part of their testing routine.

The Magic is a twin tuner PVR ( records two seperate streams) I think what Wklie is getting at is to try to isolate tuners to see if there is a fault on one of the tuners. I haven't taken the top off mine but wonder if there are two separate tuner chips and not combined. I have filled nearly 3 Tb of diskspace its about time I deleted some of the old programs that I will never watch. ABC and SBS usually repeat after a few months anyway.

You may try to verify whether the signal reception is restricted to one of the two tuners by:

- Reboot the Magic TV in Settings -> System, or using the rear power switch

- Start recording the current channel (regardless of whether it gives a proper TV picture on screen)

- Switch to a channel on a frequency that is different from the channel being recorded

Yes, this is what I meant, and yes, there are two MxL5007T chips.

Well I only saw the aerial fed into the one item inside the MAGIC the other day. If there are 2 chips then they were hidden inside this unit which had nothing identifying it except that part number previously quoted. And, assuming there were two MxL5007T chips I guess that if only one chip was faulty then it would revert to being a single tuner unit - no such behaviour was seen. And I have not seen that "No signal" message since spraying the contacts so maybe it is a storm in a teacup. I really hope so because using the other PVRs after the MAGIC is like reverting to the dark ages.

No, tuner failure cannot be detected so it'll not revert to be a single tuner unit in your case.

If it is indeed a contact problem inside the Magic TV, re-soldering the MxL5007T chip (if you find out which one, or both chips) may help, but this is not common, and it requires a certain level of skill to do it well.

OK. If it reverts to periodic "No Signal" messages I'll pull it apart and examine the soldering. Dry solder joints are not uncommon in electronics as it ages and that could be the answer.

But getting at the underside of the motherboard to inspect is not a quick proposition so I'll postpone it until there appears no other answer. And I'll try out that new power supply first - that will be a week or more away yet.

Thanks everyone for your suggestions. It is important we keep our MAGICs operating for as long as possible so sharing experiences/suggestions on this board is of invaluable help.

VERY bad weather again last night - wind and rain so the MAGIC was unusable. The video periodically pixellated and the "No signal" message displayed. Even the DIGITEL STB showed the occasional stress but was watchable. So all viewing on the main system was with the satellite PVRs - coming into more regular use than previously anticipated. I did not try connecting the aerial into anything else as I did previously.

So, my conclusion is that there is probably nothing really wrong with the MAGIC and the sad fact is, that although its tuners might be better than many (e.g. those in the REGAL TVs, the SONY STB, the terrestrial Humax) , they are not the most sensitive around. In this house that laurel goes to the DIGITEL. Maybe there was a less than perfect aerial connection when these problems first surfaced and the electronic cleaning fluid helped but the borderline signal is proving too challenging at times.

Bottom line is that reception here drops off badly in the hot summer months and, with the latest aeria,l and it now appears to do the same in very windy wet weather. That still leaves a lot of the year to use the MAGIC.

It does seem that different aerial designs have different weaknesses. The present Fracarro Sigma 6HD http://sigma.fracarro.com/download/datasheet_SIGMA_6HD_eng_extraUE.pdf, installed last summer, had a proven stonger signal that the one it replaced and was far better than a phased array, but I've never had reception problems in winter before. One earlier aerial trialled was strong on ABC & SBS but weak on Southern Cross while another dropped out constantly with SBS but was strong with Southern Cross. Neither of these two dropped out in winter. Seems the Fracarro is very sensitive directionally so that strong winds mess up the reception and the rain cause nearby trees to act as shields.

But I'm off topic so will shut up.

Have you tried using a TV signal booster? (Although it is not generally recommended for use with Magic TV, in case of very low signal perhaps it may help in certain scenarios.) If the channels for your area do not need VHF, adding a diplexer to remove VHF often helps. If the noise is too much because of amplification that you cannot adjust, trying out different values of attenuators may help.

Yes tried that. I did have a powered splitter at the input for the MAGIC & other items but removed it and put back the ordinary splitter. No difference was observed in either signal strength nor quality on the MAGIC meter so, for the reasons you state, it seemed best to take out the powered splitter.

I've been down the road of masthead amps, distribution amps, ..... Everything possible has been tried over the last 5 years with advice from guys on DTV, the digital authority, 3 installers, ...so I'm finally to the position of admitting defeat and handing over to satellite reception during the "challenging" reception times. This is a great relief to my present installer - great guy but he did tell me many times the only solution was to move (out of the question) or go to VAST. At least there is now a choice of STBs & PVRs for VAST except they are all damned with Freeview thanks to Optus and commercial interests. They made sure the protocols for VAST were so unique we would be forced to buy specialised gear and could not use one of the many other satellite PVRs around.

Of course there were no vested interests involved. :pirate::purple:

I would like to move from the 4000 firmware to 3700 firmware to gain the series recording function. Are there any special procedures to do so? Is there a link back to the primary differences (ie what functionality I will loose) when moving to the 3700 firmware.thanks

As far as I am aware all you need to do is download the 3700 firmware Unzip to a USB stick and away you go. I think there was a post on that towards the beginning of the thread. Note if you have a WiFi dongle I would remove that first and I would recommend doing a Factory Reset first and then after applying the firmware ( probably not necessary but seeing as it is a big change might help. ).

Not sure of all the Freeview restrictions but the major one that most people dislike is the lack of the skipping function.

You will also need to enable the Freeview EPG instead of the Magic EPG to get the series record feature.

I suppose if you don't like it you can revert back I have to say the latest 4000 firmware is just about perfect for my usage.
