TV clicks on, and tries to turn on for about 5 seconds, then shuts off.
If you try to do this 3 times in a row, it will go into protective mode and you have to unplug the set for about 20 to 30 minutes before you can attempt again. It never shows any picture and always shuts back off after 5 seconds.
Main board was sent for testing, and is good. Power supply never produces VS or VA voltage, however I have no idea how to bypass all that stuff to isolate it.
I do believe I have a bad SC board and maybe a bad SS board.
SC board TNPA4848AG
D421 the legs labeled A are shorted to ground. Noticed IC521 had 1/3rd of its legs shorted to ground, but IC501 had none. They are the same IC just in different locations, so I think something is wrong there.
IC561 has pin 1, 10, and 19 shorted to ground but IC562 only has pin 10 shorted to ground. Once again same IC's just different locations, so I think something is going on there as well.
If I am correct in assuming these IC's are supposed to have the same readings, then which ones of these are good and which ones are bad? I checked my SS board TNPA4774AG and it has the same 2 IC's only this board only has one of each and both of them are registering the same shorts as the ones on the SC with shorts. So does that mean the IC's on my SS board are bad as well or that the IC's on my SC board that do not have the shorts are burnt and not having proper connection?
Any help would help. I did not get the part numbers of the IC's but if needed I can get that for you guys.
Also pictures are not posting for some reason, I will try again in a bit.
