Panasonic Rear Projection TV -dark picture

Model PT 51844A, Mfg Aug 1999
Picture darkened basically overnight, turned it to max bright...little help.
Sounds like a lamp, 1st time to change...had back open, saw 3 lamps which seemed to be lit up yet are they working...???

Is there another spot for a lamp that I am missing?

Re: Panasonic Rear Projection TV -dark picture

First off I think you meant Panasonic PT-51G44A which is an AP815 chassis. That unit has an all to common failure of the capacitor at C581 on the D board which is a 33uf/160v cap. Replace it and I think that will solve the problem..

Re: Panasonic Rear Projection TV -dark picture

Hi premtech, i finally found an electronics store that had the cap and that would solder it in place on the board without having the tv at their shop.
i carefully took out the D board and brought it to the shop, then after he soldered it, i put it back in place in the tv. the dark screen left, but now there is a strong red tint on the screen. i've tried to adjust by the "picture" options and that has helped some. any ideas?
FYI: i subscribe to comcast and when on pause mode with their dvr, normally after 5min or so, the screen goes black with the current time displayed. now the screen goes dark red tint.''
-any other ideas?

Dark picture

@ 6 years old I'd be willing to bet that it's time to replace the lamp. They lose brightness over time so that could be what the problem is.
