Never had a problem w/ my 82" until few months ago - 45 days after squaretrade expired..... Unit would periodically just shut off but never could find a code for the problem as it was very intermittent.....
then one day I turned it on, heard a loud pop and smelled something burnt from the back and never powered on again, no lights or code at all... completely dead now.
Haven't pulled it out yet to check and see what burnt(bulb is fine) cuz it's kind of hard to get to but just wondering if anyone knows the part numbers for the power supply or the main board in this 82" - curious if any parts from my old 65" or a neighbors 73" w/ dots could be recycled for this 82" before I dig into the problems and tear it apart......
I have access to a WD-73638 and hoping it uses same parts as my 82", if anyone knows for sure would be great help before I rip it apart......... have to double check on my 65" model #
I'm not sure about the 73638 using the same parts or not, but the part # for the power supply on your 82740 is:
They always say to check the 02 # on your board to make sure it is highlighted in red.
You can't get a new power supply anywhere, but there is a guy on Ebay who sells them used. He's asking $100, but he will take $75. Here is the link:
The bad news for you is if your main board is bad, then you are out of luck. I can't find anyone who sells or works on those boards.
I'm in the same boat as you. My 72840 got hit by lighting and I know it has a bad power supply. I think the main board is bad as well but don't know how to test it to be sure.
I would buy a power supply and see if that fixed it, but I don't want to spend $75.00 because if my main board is bad, then I have no TV and I'm out $75.
I'm hoping I can find someone who has a main board for sale, then I will purchase a power supply. At least that way I would be in position to buy a main board if I needed it.
Here is the part # for the main board:
If you happen to find someone who has them, please let me know.
