TV Repair Questions? Ask a TV Technician for Answers ASAP
I bought the set 5ish years ago as an open box return from best buy...
the noise has been here for a good 4 months... but is progressively getting louder
I think its coming from the tv itself because its there when I am using my ps3 which is plugged into external speakers
Yes I plan on doing this myself.
do you happen to have those part numbers handy?
also if it turns out to be the LED Engine or DMD board do I need to reconfigure anything?
I'm sorry for the delay. The part that would be most likely to be causing the problem, would be the LED Engine, or the LED driver board.
The LED drive board is unavailable anywhere I've checked. The other option is to purchase the entire LED Engine, but this part is very expensive, and these sets are basically obsolete. I hate telling people that about their very expensive TV's that develop these faults, but this set was plagued with problems that we've seen commonly in the field. The LED chips are prone to failure, the DMD is prone to failure, and the LED driver and Light Engine are also common problems.
The only source I could locate the entire engine from, is a site that is higher priced than most.
You would need to check the part number against the one in your set, as there were 2 revisions of this board.
If you need further assistance let me know and I will continue further. If you're satisfied with the service, please do not forget to rate the answer.
