Hi there, my first thread here.
Have a SAMSUNG LA40N81BDX that behaves in the following sequence:
1. Power button is pressed
2. Clicks on like normal, blue light near samsung logo turns on, backlight flickers on
4. 5 seconds later, back light turns on while coloured vertical lines progressively fill the black screen. The lines are solid.
5. 10 seconds later, another click is heard and everything is switched off.
6. Repeats
I have deduced it to be the main board, rather than the screen/t-con board due to the fact it is switching off and having no response to the remote. Have already changed the EEPROM and already tried heating up the processors with a heat gun.
Anybody else have this sort of experience? I want to try repair the board to component level because they are expensive/hard to find.
