Re: Sharp Aquos LC-46D64U stand by with new boards!
So, at this point, the problem can fall under two categories (or a combination of the two).
A) Software/firmware errors which can't be fixed/cleared/flashed via the USB firmware update (possibly due to another board's hardware failure).
B) A hardware failure.
C) Combination of A&B.
As for 'B', the only boards that haven't been replaced, are the 4 inverter boards and the t-con board. The power supply board was replaced, but didn't fix the issue, so I returned it. If it was faulty in combination with the bad main board/tuner board, then I will still need to replace the old power supply board that is in the TV. Although I don't think the power supply board is wrong (please let me know otherwise), I am willing to test it with the meter wherever necessary as I am directed to do.
I am willing to test anything on the inverters and such as well; I just need some hand holding. There was mention of testing a few components on these boards earlier, but I was weary of trying them (due to high voltage and such); I had hoped that changing out the main board would alleviate the problem.
Where should I check next?
