I'll quickly recap the situation and the symptoms I had regardless:
- PJ 4-5 years old, only 250 hours on the first lamp.

- Unplugged the PJ before going on holiday for 3 weeks
- Plugged it back in when we came back, had it on standby for 2 hours and then fired it up
- Turned on fine (no lamp flicker, nothing out of the ordinary) but then all of a sudden cut out with the 2 amber light flashes.
- Unplugging and replugging to reset it and then firing up had the same outcome every time
- Had it just sit in standby for about a week without doing anything with it and decided to fire it up again: didn't cut out anymore, no amber lights! However, significant amount of flicker present.
- Putting it in high power lamp mode there was no flicker... for about an hour, then flicker started here as well.
- Got in touch with JVC support and an authorized repair center and they warned me that it may not be as straight forward as a mere lamp replacement which had me thinking twice about just going out to get a new lamp. The way they said it gave me the impression that they felt it was more likely not a lamp issue...
- After reading up on the symptoms of similar failures on AVS, I rolled the dice and started working under the assumption that it was more likely to be the ballast, especially given that my lamp has such low hours and it was only ever turned on to watch a movie and then turned off.. was never used as a turn on/turn off television type setup.



So now...

- Is there any other way that I can determine whether this is ballast and/or lamp failure?
- How likely is it that I have to replace the lamp anyway if there has been ballast failure?
- Anyone in Melbourne that has an X500 that I can take my lamp to to try out?? :cool:

Two blinks of the yellow LED (in the center) indicate a failure with the lamp (Lamp extinction during the design).
If the new lamp does not fix the problem, then you will need a thorough diagnosis, in a specialized service. You can assume anything, starting with the fan not working, the power board, and up to the processor board. Therefore only in service.
As for the ballast, that they work for a long time and rarely fail, I know from experience. Sometimes I repair projectors.

P.S. If the lamp flickers and does not heal in high mode- change the lamp.
In addition, the failure of the ballast produces a completely different error, the diodes blink differently.

Hi again, thx for the feedback but are you basing the fact that ballasts rarely fail on a general principle for all projectors? Or are you talking specifically for my model and the more recent ballast that was introduced? Because the previous gen JVC sure seemed to have quite a few of ballast failures so generalising that ballasts don't usually fail would not have applied to the previous gen and as a consequence that statement may or may not hold true for mine.


The manual on my JVC states that in the case of a 2x amber light blink there is 'abnormal circuit operation' (see attached pic). So this could be pretty much anything but actually seems to rather move away from the assumption that it would be lamp related.
From all the symptoms that I have found pertaining to some of the previous gen with ballast failure, mine is seemingly exhibiting very similar behavior which has led me to believe that this is more likely to be the ballast.
But of course this is still very much a guess so I'd be very happy to hear how I would be able to determine where the fault sits without incurring crazy authorised service center investigation costs.



I could have gone out and bought a new lamp but didn't want to get stuck with a $500 AUD spare lamp that I was not planning on using (since I want to upgrade to one of the new models that will get released towards the end of the year) but of course there is even less point in having a spare ballast at $300...


I don't really trust repair centers either as they can claim anything in terms of what is wrong with the projector and for example, if it were confirmed that it is effectively a ballast issue, they may still claim to have swapped out the lamp as well and charge you $800 excl workmanship costs for a projector that is probably only worth $1500 AUD anymore...

The problematic ballasts were and remain in the X3 -90 series and, naturally, also in the reference ones. Since X35 ballasts are already good, do not break.
The lamp does not necessarily have to buy expensive, you can take for example such- https://www.ebay.com/itm/Ushio-Orig...2312UP-PKL2312UP-Projector/113086581834?hash= item1a547c4c4a: g: EFYAAOSw0URbV8sb
At least to verify it will do.

Ok great, I'll try that first then! :)
When I was researching lamps before jumping onto the ballast thing however, it was mentioned that these OEM lamps do not hold their brightness as well as the JVC ones. Is there any truth to that? That's one of the reasons I originally didn't consider to go down that path.

But you're right in that it is probably the least expensive way to determine where the issue sits and if it's not the lamp at least I have something extra even if it's not the same quality of the JVC one.


Thx a lot for the ebay link and the assist! I'll report back once I get it in.
Just a shame that I've opened up the PJ for nothing now :D
Could've spared myself a lot of grief :rolleyes:
But at least now I know how to do it in case it does prove to be something other than the lamp ;)

Actually, this is one I came across in my initial search that is closer to home (and so will arrive a lot more quickly too!) and also works out to be more cheap after delivery.
https://www.ebay.com.au/itm/Project...=15&_sacat=0&_nkw=PK-L2312UP+&_from=R40&rt=nc

As said, did have my concerns about them, but if you're saying the Ushio ones are just as good, I'll bite the bullet right now!

Take that lamp that is closer to you is located, which is cheaper going out. For the experiment is absolutely accurate.
Ushio is a very good lamp, if not fake.
P.S. It's very hard to communicate with the auto-translator, it does not translate correctly, so I do not quite understand what I'm talking about sometimes.

I had a quick look at their feedback as I thought I could get a spare for my X900.



Most of their stuff ships from Hong Kong.

Yeah I noticed that as well, which is why I sent a message straight away whether this item was located in Oz or overseas...
Hasn't come back to me yet which is not inspiring me with confidence.

The positivie reviews all mention fast shipping though so he must have stock in Oz somewhere. However if you've got my kind of luck the lamp will be the one thing he doesn't stock here...

Just an update: put everything back together again (without actually screwing up on reconnecting on any of the wires apparently :D) and it gave me the same result. This time it fired up without a hitch whatsoever but the joy was short-lived as I realised that it was still set to high lamp mode. After about 10mins the flicker started and when I then switched back to low lamp the lights went off shortly thereafter followed by the PJ shutting down and giving the 2 amber blink again.


My symptoms are actually very much like this one where it turned out to be a ballast issue:
https://www.stereo.net.au/forums/topic/231811-jvc-x30-lamp-light-flashing/


Anyway, I've gone a slightly different route now to securing a new lamp in hopes that mine turns out to be different and is effectively a lamp issue.
If I order through myprojectorlamps.com.au, while obviously more expensive at $338, I only have a $25 restocking fee in case it turns out it is not the lamp. I called them up and asked if they are ok for me to try out the lamp.
If it turns out it is and the lamp itself is as claimed (i.e. original bulb in a generic housing), then I will probably just keep it as they're the ones helping me out (which is probably also what their business model is about anyway but hey, if it works for them).
If not though, I'm not down by $150 and I can try to get my hands on a new ballast in hopes that that cures it.
In that case it's back to the old screwdriver though, but I'm now well positioned to open her up, fix the innards and close her up in record time ;)


Thx to all that have chimed in to assist!! Much appreciated. Will let you know how it all turns out ;)

Reviving this thread as I seem to be suffering the same problem :(
However, I've just removed the ballast board and checked the resistor that seems to be a common issue in the several threads and sites I've been reading, but it looks to be fine...

I have a more detailed thread at the AVForums: https://www.avforums.com/threads/jvc-dla-x3-not-powering-up-help.2181307/


I've not checked the optocouplers (Fixya) or the IC1 that was mentioned in another thread on AVforums though.
Since the resistor is fine, I'm wondering if it really is the ballast board that's the problem... any ways to figure this out? Another lamp didn't make a difference.

My exact symptoms:
When powering up, lens cover opens, status LED goes green. Nothing more happens though, and after ~30s the status LED goes red, the lamp LED blinks orange and the warning LED goes red.
I can at that point do nothing other than unplug the pj. It then does nothing, until I manually close the lens cover and try firing up the PJ again - it repeats the same behaviour.
I've tried with another lamp, but that's giving the exact same result.
Ideas?

Yes, your case suits the problem with ballast. You will have to buy a new ballast board and install. The problem should disappear, the projector will again work, until a certain point.
In these ballasts, there is an initial error, so they are out of order.
If you want a "modified", corrected ballast, you can contact me. But, I'm in Russia.

I noticed someone from Shenzen is selling X550 ballasts on the bay now. I wonder if they would work in a 500?


It looks different.

No. It will not work, because the lamps are different. For X500 a lamp of 1300 lumens is used, and for X550 (RS 400) in 1700, respectively, the power supply unit is different, and ballast.

Has anybody tried this one?


https://www.rushsupply.top/compatib...jvc-dlax70-dlax9-dlax90-rpb0526ga-p-5141.html


It showed up searching for RPB-0526GA, the model of the original ballast. It's listed for X70, X9 and X90 though. Do these have the same ballast board?
This is a bad fake. Will it work or not? Most likely it will be, but what will happen with the lamp, power supply, processor board and other components is a big question.
Look carefully at the original ballast and this one The questions will disappear, I think.

Also, the wires with the lamp connector seem too short. Soldered, that is bad. There may be problems installing this ballast into your projector.

So another update since I just got my new lamp in... same prob so probably the ballast after all. I hate when I'm right about these things 😞
Put the PJ back together for nothing. Will now need to try and source the ballast and hope it doesn't take a year to arrive...

Well maybe you can pull the big metal bracket off without removing the main board. Can you see if there are any other screws under the board?
Hi Luc
Based on your experience with ballast problem can please suggest me some tips ….is this issues I have points
a defective BALLAST!

DLA-X3:

Indicator lights were both on red and lamp light flashing orange.
Replaced the lamp and it did not change the status, did cleaning filter bit , did lamp reset from the remote ,
did reboot and plugged it at a different ac outlet all that did not work .
The lens cover is stuck at opened and the only thing you get when plugged in is the red light on and after 30 seconds the lamp light comes on orange .
No fan came on no moving lens cover only flashing orange light.
