TV Sharp LC-49CFE6242E - not working - 2

[betmen]

I wrote a topic earlier for this TV...https://www.badcaps.net/forum/troubl...2e-not-working
I managed to fix the power supply but there are still some faults. The sound works a little and then doesn't work a little and the tv doesn't respond to the remote control at all (I've tried several remotes).
I suspect the motherboard...is there anything that can be fixed or does it need to be replaced?

Do you have a programmer that supports NAND Flash, if so, then read the dump of this NAND and post it here, I will check it and clear it of bit errors...
