(1/5) > >>

mali67:
I have an ONN 42" unsure of the model but has the vestel 17pw20 psu.
all voltages seem correct,
problem is when first turned on picture with stay on for upto 5 seconds then go off i still have sound
there are 2 15bf 630v caps that look ok but suspect they could be part of the problem, i dont have any of these to try is thee an equivelent i could try ? could it be something else ?
cheers

sparky:

mali67:
no the backlights go off
ive tried another inverter

Turnip:
Hi Mali67,

Would always change those 15nf/630v caps supplying the 24v line feeding inverter - heaps on Ebay. They don't always bulge but are the first things to check - replace anyway, they're cheap - Chris.

cheers chris i looked on the bay but couldnt find any 630v ones, cheers robbie
