I'm also interested in hearing about people's long-term experience with 3rd party lamps.

I recently bought a used X30 with only <600 hours on the lamp. I decided to buy a "cheap" lamp for comparison (and spare), and essentially just bought the cheapest one I could find on eBay, from the seller QualifiedLamp, for $55. The lamp does not have a flap, contrary to the picture.

To my surprise, the cheap lamp has essentially the same brightness as the original JVC lamp (with 600 hours). The colour balance and colour gamut are also comparable to the original (measured with an X-Rite Colormunki Design spectro, HCFR software).

It's too early to tell how long the lamp will last, but so far I'm happy. I'm running the projector at the lower (Normal) power setting, so hopefully the cooling is adaquate without the flap.

Keep us posted as you go with that cheap lamp.

Will do. Considering the low cost, I would be satisfied if I get 700 hours out of it. However, at the rate of 2 hours per day, it would take me close to a year to get to that. I will report back if I notice any premature dimming.

Sounds like an old version 1 or version 2 JVC lamp. Those did not usually last long and is why JVC had there lamp supplier rework the lamp design. JVC replaced around 40 lamps for my customers that received the version 1 and version 2 lamps that died early.

X30 HDMI Inputs Broke!

I was plugging the HDMI cable from my laptop to the X30, felt a little electrostatic spark discharge, and now both HDMI inputs show "No Input Signal". The projector still works with component input.

Has anyone else experienced this problem? Is it an expensive fix?

So I bought the JVC RS45 in 2012 and finished my theater in November 2012. I now have 599 hours on it. I initially used it at the normal power lamp setting and it was great. However, about 6 months ago I noticed that I was having more trouble with dark scenes in movies and television so I switched to the high lamp. Now, even on high lamp I am finding it more difficult with the dark scenes. In brighter scenes, it looks great. So is this normal wear and tear for the bulb and should I just get a replacement, or is this amount of dimming too rapid and a sign of a bad bulb? Thanks in advance!

Have you tried adjusting your aperture setting?

I'm out of town on vacation now so I can't tell you for sure. Just find the aperture setting and adjust it to the left, I believe, and see what happens. You will lose some contrast though.

If you have never adjusted it, it would be at the factory default value of 0, which is the brightest already. It can be reduced down to -15.

Unhappy JVC x-30 not starting any ideas?

Hi,
I am new here on the forum and maybe this has been answered before, but I can't find any post regarding my problem.

To the problem
The projector has worked fine for most of the last 3 years on rar occasions on powering up this senario has played out:
When I start the projector the standby light shines green and after a short while the the standby light turn red, the warning light turn red and the lamp light turn orange and blinks - and the only thing left to do is pull the power plugg.

During the rar occasions that this happened in the last 3 years just pulling the power plug and waiting half an hour and the trying to power it on again solved the problem.
Now in the end of last year the replace lamp massage stared appearing and I bought a new original lamp after replacing it every thing was fin for 3 months and then the old problem started to occur rather frequently and then all of a sudden the problem did not go away by pulling the plug and waiting a while.

so I have bought a new lamp, replaced the three month old one but the problem remains, and it seems to be permanent ?!?

Have any one had the same problem and maybe know what is wrong and how to fix it?

Is there a way to connect to the project without using the onscreen (now not working...) menus like with a network cable or som other way?

regards
Christofer

Sounds like a bad lamp ballast. Regardless, it will need repair, likely from Mendtronix. GL.

I was using the projector for a while with the Component Video input. The repair cost was estimated to be C$300 to C$800, depending on whether the entire board needs to be replaced.

Yesterday I decided to try to HDMI input again, and it worked! (Don't ask me why or how). I'm happy now and will be super careful when swapping cables.

Hi Christofer,

I'm having the excat same display from the front LEDs. I was watching a movie and suddendly my X30 went black and it does show this error message (with leds) every time I swithc it up. I've tried to change the lamp but have the same behaviour. On my side I was wondering if the "new" lamp was damege due to transport ?

One question for you, does the fan starts when you power up your X30 ? on mine the fan never starts even for the 5-10 seconds before the orange leds blinks ?

Thanks Richard

Hi Nightfly, is it possible to change this ballast myself? I'm having some skills :studied electronics and built several Tube amps (high voltage) ? However, It may be difficult to order the part ...

Thanks,

Richard

If anyone could get their hands on some ballast boards for the JVC models I'm sure they would sell out quickly. Weak point in the series, maybe.

Yeah, and who knows if that is the problem or the only problem. I think one would have to be able to diagnose the problem and then try to source the specific replacement parts - maybe from Mendtronix themselves.

Looks like the Ballast for the JVC X30 has already been identified as a Rubycon part... on page 146 from this thread

It seems available (for special orders) at several locations on the web by searching with google and QAL1305 & JVC

Sorry I can't post links since I have too few posts ;-)

But I agree that it is worth having the projector checked by a professional to ensure that it is the only problem? I've found a JVC Center next tpo my home, just need to find some time to bring the (heavy) JVC there.

Thanks for all your replies,

BR,

Richard

For the first time I'd been using a lamp that had always been using the grounded power with the nice power filter, and it died today, 788 hours in. I tried doing high lamp mode, but after about an hour it started flickering heavily there, too.

With grounded power that goes through that nice filter, I can't believe that's where the fault lies any longer. The projector has to have been damaged somehow, I guess in the power supply. But JVC has stopped helping me and I'm about to lose my contact to the hi-fi store in which I bought the projector as he's taken a new job elsewhere.

Not looking good right now. I'm stuck with a dodgy projector that eats lamps for breakfast. Almost $1 per hour is way, way too expensive
