Hi!The tv does not react at all when you hit the power button?Tim
It dos not respond.When tv left unplug from Ac for fore day or more it will turn for about
an hour then will shut down and wont turn on again.Now wont turn on at all.It heppens with both power boards.Did traysustituting bck light lamps on by one ,noefect.
What did you do with the backlight lamps?Tim
Tey ae stil in tv .I used my test lamps.
What was making you think that the lamps were the issue if the set is 100% dead and not responding to the power button?Tim
I told YOY set gos on after sittin unplug from ac for 24 hr.stays on for 1~2 hr then gos of and wot turn on again.That was heppening with bed lamps on diferent sets.
OK yes but bad lamps will never stop the tv from at least trying to come on.Test the DC voltage on the wires between the control board (board with power button on it) and the main board. Press the power button, what happens? (do this test when the tv is not reacting to the power button)Tim
The rail to power button stays~3.3Vdc. gos to 0 with power button push in.
Ok then you have a bad main board here.Tim
It wont be a lamp at this point, there is no way a lamp could cause the tv to be 100% dead. They can cause it to shut off of course but not be 100% dead.Its going to be the main board, I would replace it at this point without question if I were you.Tim
