I figured out my problem!!! i kept googling around for an answer and found it in a just*nswer page. basically. my symptoms were, I turn on the TV, the lamp comes on, dies in a second. and tries again a second time and dies. TV remains off. repeated tries to no avail. I read about the power supply a...

Well... thats interesting. I installed a new power board and the measurements were different. However... not like I'd thought theyd be. Now the difference between ground on the tv chassis and ground on the ballast board is 150V. I'm not quite sure why that would be... but at least its different from...

Ok.. I'm back unfortunately. The replacement cap I used finally gave out. It was much more durable than the factory one though. I'm seeing the same symptoms that I mentioned in the first post again. I opened up the TV and the cap I replaced was smoking hot... and this was 5 minutes after it had alre...

Thats exactly what mine looked like...

I did smell something burning when it went out. Would the ballast still be bad even if it can power the bulb on? Do you know where to get a whole new ballast? discount-merchant does not seem to carry them. I may try a power supply, because as you state, you have not 100% solved the problem. I will ...

I hope someone can help with this thread. I have the exact same TV with the exact same problem. It is about 2 years old as well.

Ok. I'll give the fan a shot. The second ballast brd is shot... I tried it again last night and it instantly turns on and off. I'm going to try to replace the suspect capacitor first to see if I can fix it cheap... Thanks for the advice... I'll be back in a little while....

Friggin A.... So... I installed the new ballast and kept using the old lamp. IT worked fine for 4-5 days but just now I smelled the same smell (the big blue cap melting) and I turned it off quickly before more damage could be done. So... What now? Could a lamp be causing this? Or the power board? Bo...

Nightkid,
Sweet... that's what I was guessing. I ordered a new ballast and lamp (mine is 2 years old anyway) The ballast gets in on Wednesday so I'll try that with the old lamp first. Thanks!

Oh Gods of the DLP forums... please help diagnose my problem. One night my HL56A650 started turning on and off and smelled of burnt electronics (actually I thought someone was BBQing at 2am.) I think I have it figured out, but I want some untainted opinions from the helpful folks on this forum. Here...
