TV started of with tab intermittent tab issue.
Fixed and working for a couple of days, then foggy image started to appear and after about a minute the tv picture would black out over period of 1-2 second, back light was still on. If power off and on it would repeat.
Now have the 5 flashes of red light then red light goes out situation, back light not going on now. Cooling fan is spinning. After about 1-2 minutes it repeats cycle or if power pressed again it goes into standby and then when power pressed flashing as before.
Caps all look ok with no physical issues.
Checked all the outputs to control board on CN801 and all ok (volts etc match, assuming power on/off of 3.65v ok as not stated on board). cni803 has 1 inverter of/on(4.9v), 2 ana dim(3.34v), 3 pwm dim (1.83v), 4 grd (0v), 5 det_5v (5v). Not sure if these are ok apart from grnd and 5v one.
Both fuses ok on power board.
Anyone any ideas
would be greatly appreciated before I throw in bin
