Question about Televison & Video
It does sounds lkie the symptom of bad T-CON board, you can try cooling it with electronic freeze spray for troubleshotting, more likely to have bad IC, most repair I do is due to shorted out DC filter caps such as the one in INSIGNIA/DYNES NS-LCD37HD (backlight is on but no picture due to bad T-CON board):
I spent many hours to locate the shorted out surface mounted caps it was time consuming becuase they are in parallel, but Iwas able to find it since I do not want to spend $80 for a used board and I have nothing to lose.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:
