Have TV Questions? Ask a TV Technician
Hello, Please tell me where you're getting these Lamps from.
In other words, are they $35 Amazon/Pureglare specials, or are they the correct OEM $110 Osram lamps?
The reason I'm asking is that the dim picture is either a lamp issue, or a ballast/power supply issue that involves replacing components within the TV. I would like to rule the quality of the lamp out as being a possible culprit.
I'm unsure why you logged off as I'm here to help you with the question you posted?
Thanks. I saw that you leave the set on 24/7. I've personally in the field had more bad luck with cheap lamps since they actually put a burden on the Ballast and power supply. So again, you've either got a bad lamp (although you said you tried two) or the ballast or power supply have weakened/are failing. There are no pushbutton fixes for this, and the choice its up to you as to how to proceed, but in the field we ONLY use OEM Osram lamps and that very well could cure your issue, however there's NO WAY to determine that without purchasing that lamp and replacing it. If the screen is still dark then voltage testing from the ballast to the lamp, and power supply to the ballast needs to be done to isolate between the two boards.
The OEM lamp for the set is available at the link below if you'd like to try that route next:
Beyond that, if you're looking to repair the set yourself you will need a multi-meter, and to be comfortable measuring live DC voltages within the TV. The DC output from the ballast needs to be checked, as well the power supply board's output to the ballast also needs to be tested. These parts are generally available at the link below:
Alternatively if this is not something you're comfortable with, then a shop will typically charge between $350-$400 parts and labor provided the Lamp is not the root cause of the issue.
Otherwise I'm sorry for the bad news here and wish there were a quick fix.
