Jvc x30 lamp light flashing

Recommended Posts

My jvc x30 just stopped working. Standby and warning lights are solid red and the lamp light flashes orange twice at a time. Is it just a lamp replacement or is it something worse. Worried it might be something worse as I don't have my spare jvc hd550 anymore as a replacement :(

Did you hear a pop or did the lamp just go out?  

These are not like DLP where if the lamp explodes it can take out the colour wheel.

No pop, it just suddenly went dark. I do have to mention I hadn't used it for like 2 years and then started to use it again when I had set up my room and that was only like 2 months ago. Also since I had started using it again I did notice a couple of times while watching it that it would go blank or for a second or so then the picture would come back. Does that sound like the lamp was going? I hope it's just the lamp and not anything else.

Not sure why you would see a blank or black flash.  Could be a sign, I've never seen that though.  Normally lamps at end of life get yellowish around the edges of the screen.  Most noticeable on full white fields.  

If it didn't pop, then you should be OK to plug-n-play a new lamp.  I'd still change the air filter and give any vents a vacuum to rid any built up dust.

I am thinking the black flashes may have been hdcp or hdmi issues. So may not be connected. 

So I can use a vacuum on the external air vents? Is it safe?

Bah looks like the bulb from the  hd550 won't fit my x30. I thought they used the same lamp. Where's the best place to buy lamps?

Is it easy to just get the lamp and change it in the housing module? I don't really want to do soldering etc. can you just click it on or something or does it require some wiring and things?

Couldnt decide where to order myprojectorlamps, justprojectorlamps or ozlamps. In the end Ozlamps seemed the cheapest. They all seem to have the option of original lamp in a generic housing which is the option i went with. I noticed that justprojectorlamps seem the only ones that have original lamps and housing straght from JVC? but they are pricey in comparison.

 

Hopefully ozlamps is reliable and good :). I got too scared of getting just the lamp and using my own housing as the ozlamps guy seemed to think its not recommended unless you are a tech and the warranty they provide if you use your own housing is only 90 days instead of 180 days if i buy the lamp and housing from them.

Just open the suction valve on the hose if your cleaner has that or don't make a seal and let the air just take away any dirt, fluff etc.  If you have one of those clip on brushes, use that.  It will prevent you from making a full seal and it also helps reduce scratching the shiny plastic case.

the issue is the dust is actually like inside the vented area on another vent or something. Like its an inch or 2 inside from where i can get at it. I can only see it through the vents on the corners of the projector. Hard to explain, I dont think the vents open so i cant reach through the vents and the vacuum isnt strong enough to suck it with a gap of an inch or 2. I could maybe try poking through a small brush if i can get one to fit through the holes but not sure thats safe and that might distribute the dust internally..

Yes the dust tends to build up and pack in tight.  A small brush might be what you need.  However, you will want to have the vacuum cleaner going so it can suck out this dirt rather than let it fall inside somewhere.

Yeah thats what i was worried about, i will try to take a pic of it. I dont think i will be able to reach it either way sadly.

Suck out what you can.  If you can reduce the built up dirt, then that has to be an improvement on air flow over you had.

I just replaced the lamp with the new one I bought and no go. Still the same problem. No noise besides the led going from green to the warning lights after 10-15 seconds. Sucks. So now I have to figure out where to take it for repairs

Hopefully they can get parts quickly :(, I did buy a Epson EH-TW9000W second hand a year or so ago and never used it as i had the JVCs anyway (sadly i gave my older JVC HD550 to my bro so thats no longer available for me to use) but i can use the Epson in the interim period while the JVC is being repaired. Hopefully it works, I never even tried it since buying it second hand...story of my life :(

Is that a part of the actual lamp housing or in the projector itself?  

I've seen so many people just replace a lamp (only) to a save a few dollars and not replace the entire unit.

I replaced the whole unit, so i think the ballast is separate from the lamp housing, I presume its what the lamp housing power connects to.

      Hi all, I'm not writing a complaint as such but has anyone else had issues with their JVC X500,  or related, where it doesn't seem to stay in focus? 
      Every time I turn it on I need to refocus it. Even if I save the lens memory and recall it, it doesn't seem to remember the focus, it's slightly off. 
      Even after watching an hour or two of content it seems a little out of focus again. It's only minor but I can tell and am fixing it constantly. 
      My screen is a fixed frame just for reference. 
      If anyone has had the same and found a way to fix please let me know. 
      Thanks

      Hi all, 
      due to an upcoming move, I am selling my JVC DLA-X700R projector, including the 3D emitter and 4 x 3D glasses. The projector has approximately 560 hours on the lamp (in low power). 
      The projector produces an excellent quality picture and handles difficult scenes with ease.
      I was blown away the first time I watched a movie on the projector, as I hadn't realised how bad other projectors I'd owned/seen in the past had looked. Our family has thoroughly enjoyed this projector, but sadly it is now no longer required.
      I have the original boxes.

      Hi all, 
       
      Due to an upcoming move, I have decided to put my Emotiva XPR-5 amplifier up for sale. The amplifier has been stored on a Quadraspire Sunoko-Vent T Bamboo Hi-Fi Rack in a dedicated media room (smoke free environment). The amp has effortlessly powered everything I've hooked up to it, from B&W 600 series speakers, bookshelf speakers, and B&W Diamond series speakers. 
       
      The amp was purchased from Emotiva USA. Given the sheer weight of this beast (42.63kg), and to save my back, pick up is preferable. 
       
      I am happy to arrange a demo for genuine buyers.

      Located in Melbourne.
    • By justifier

      As new - with Original Box, Invoice and Extended Warranty until Feb 2018! - (Item is pickup only although you can organise your own courier if you are interstate) - I am in Adelaide (Norwood)
      RRP $8,499
      JVC DLA-X75R 3D+2 Pair Glasses 4K D-ILA Projector THX RRP $8,499 Extended Warranty until February 2018! - as new
      THX Certified / ISF Endorsed / 10 Lens Memory / Native 90,000:1 Contrast / Motorised Zoom, Focus, Shift
      I am upgrading my projector (again) and my loss is your gain. This projector has a recommended retail price of $8,499!!!
      I am selling it as new (only 424 hours on the bulb) in spotless condition with original box and everything for a BARGAIN price of $4,400!!!
      I am also including two (2) pair of 3D Glasses and the wireless 3D transmitter and I have an extended warranty for nearly another 3 years which is fully transferable!
      So with over $500 worth of extras that brings the price of the actual projector to about $3,900!
      I am a very fussy buyer and this projector as no dead pixels and great panel alignment - it is up there with the very very best of home cinema projectors and a similar projector with THX and ISF Certification and a 90,000:1 "Native" contrast ratio can not be had for under $4,500. No annoying dynamic Iris's here (I can see them working) - just amazing deep blacks and amazing whites and pure colour with THX and ISF certification. The projector has also been properly calibrated.

      As you can see this is a truly outstanding projector and I am going to have to spend about three times the price to get something which I consider a little better for my dedicated professional home theatre.....
      So if you want the best you can get for less than $4,500 with two (2) pair of Genuine JVC 3d Glasses (about $195 each), 3D Wireless Emitter (about $140) and an extended warranty until February 2018 and in the Original Box then don't miss out and buy this now.
      So with over $500 worth of extras that brings the price of the actual projector to about $3,900!
      This is a bargain for this high level THX ISF projector!
      A great buy for the perfectionist and serious Home Cinema purchaser!
      Item is pickup only although you can organise your own courier if you are interstate. (I am in Adelaide - Norwood)
      Please do not hesitate to ask if you have any questions.
