I got a used Samsung UN65HU9000 and thought I could fix it. I used compressed air to clean the ribbon cable connectors from any dust. However, the problem still persists. The screen shows a green screen on startup and seems to replace the black color. Also, I do get an error warning stating that it's cooling fan doesn't seem to be working since the TV is heating up. I have the one connect box, but no stand.
I tried to clean the connectors of the ribbon cables with isopropyl alcohol and it didn't work.
Can anyone explain to me the proper procedure to fixing this? Thank you.
Probably not full boards but other parts yes. Normally TV repair is a wasted time unless you are actually doing it as a job and have a bunch of knowledge of each set, as well as have spare parts to try. There are plenty of times when people replace boards, screens, and the issue still remains.
