Hello everyone !
I am back with a new riddle for us to solve.
Ihave this Samsung LE32B350F1W television that a colleague brought to me to either fix it or scrap it.
This tv set will turn on "can hear the turn on sound" but the backlight will turn on for one secod and then turn off. The tv remains in the on state.
At first i thought that it could be a bad ccfl lamp so i removed the power board and with my ccfl tester i have turned on all four ccfl lamps and turns out they are all good.
The psu is this one BN44-00289A
I measured voltage across the main filter cap and i get 350V dc. That is pretty low as far as i remember. Should be around 380 or more with TV turned on right ?
So could anyone guide me what to do next ?
Could it be a bad PFC chip ? i dont have a replacement for that right now...
