Question about Hisense 50 Class 1080p LED Smart HDTV - 1920 x 1080, 120Hz, 2000000:1 Dynamic, 4x HDMI, Built-in Wi-Fi 50K610GW-RB - 50K610GW-RB
Replaced T-Con Board with a working board from another Hisense (same model), worked for 2 hours, then no picture replaced T-Con board again with new board, worked for 2 hours, then no picture
Hope the TV have problem with the either power board or the lcd panel. Try to check the power supply is its produce correct voltages mentioned on its connectors if you need help then check the video for that. if the power supply finds ok then you have problem with the lcd panel. In lcd panel there is a some ics which used as the driver of the pixels. the tcon sends data to these ics. and if any onf the ics draws more current from t con board then it can dame the t con. They are not replaceable one ,its integrated to the panel. if its faulty then you have to go for a new panel for that tv. And it would be a expensive repair.
