I think the color also feels a bit washed-up but I'm not sure, I have stopped using it because I'm too afraid to cause more damage.

Can someone help me if this is a screen, t-con or main board issue? TIA

Edited: adding images

PS: the photo of tcon is rotated 180'

My MI 4A TV is neither starting from the remote nor from the power button of the TV. The red light always keeps on burning in the TV, which used to turn off after starting the TV, but now it does not turn off.

My tv has no water or physical damage, was barely used, and one day out of nowhere, it started showing lines, which got worse over time, i cleaned the board and ribbons and stuff, nothing happened, even checked the tcon voltages, they seem to be in range! but to add to this, there were dead and alive cockroaches inside, also there was a lot of their $@$* on the board. which i brushed away using pcb alcohol.

so fast forward to yesterday, after a month or two, i opened up my tv, and when i simply removed the two ribbon cables, and put them back again, turned on the tv, it started and had glitches for every 5-10-20 seconds, back then, at its worse, it would glitch every second, and not even for once it would let a normal screen show.

it also occasionally turns black glowing screen, while OS still running sound coming, but it again came back automatically.

Yes, it also shows completely normal pictures too. but in between, shows these glitches too.

Would it help to know, that these were the voltage readings on the Tcon board.

VGL = -5v

HVDD - 7.9v

VDD - 16.2v

VCOM - 6.17v

VGH - 28V

Can anyone point me in the right direction? i am just a noob, who got a multimeter and normal stuff. can anyone read these symptoms and predict where the problem could be coming from? if you want to instruct me to check exactly what with my voltmeter and where.

if you will tell me, i will follow your instructions and comeback with my findings.
