Hi, This TV has corrupted firmware, first the TV would power up show a blue-ish static screen, some weird lines, sometimes the menu showed up all weird, and power down, locking up and accepting no more commands.
Unplugged main and did the AUTO_GEN test, it displayed the patterns and worked fine, of course then the problem is with the main.
Then I heated up IC802 and IC803 at the mainboard, since I don't have freeze spray at the moment, now it looks less corrupted but still shuts down in 10 seconds or less, I tried to do a service menu reset quickly before the shutdown, but it didn't change, also no idea if it actually worked.
What I'm doubting here is which Flash chip should I replace, IC802 apparently contains some sort of BIOS within, and IC803 is the software of the TV, all that is sold around here for replacement is IC802, I can't find the flash dump of IC802 also.
IC802 = ATMEL 24C64AN SU27
IC803 = I can't read the label.
The pictures are of front and back of the mainboard, and IC802/803 on the zoomed photo, the yellowed dark spots are flux, there was some minor oxidation that i got rid off.
