Display is darker than normal.

Post by schoukeir » Sat Jul 25, 2009 2:41 pm

Greeting everyone,
I have a PT56DLX75 DLP, few month after replacing the lamp with Osram, the picture brightness started fading gradually. I opened the back of the TV cleaned all the vents, checked for all loose wiring, reset the lamp, adjust brightness to the max, still the display is dark. I can still watch the TV sitting right across from it in a very dark room. I ordered a new lamp which I should have in few days. I wonder if the problem is with the lamp ( that I'll find out soon), or the power supply(ballast). If anyone one had the same problem please share your experience with me, maybe will get both our TVs fixed.

Peace
Sam

Sorry its me again,
Just wondering if replacing the ballast would increase the life of the lamp? The original ballast from Panasonic cost more than $200 (part niumber EUBMM021A10A). Is there any oem or used ballast that is compatible with it.

Thanks
Sam
