Can I see a picture?

Re: NEC Px42VM3A lost all display

if you lookup towards PH and PD connectors in slot L10 these are what I see

Re: NEC Px42VM3A lost all display

They are inductors not fuses, should test shorted.

What about that white ceramic resistor, how does it test & what does it say? Hard to see with focus, remember I do not have this board in front of me.

I have only worked on a 50" NEC chassis and it was reasonably modern, PSU made by Hitachi, main board by NEC & rest of plasma screen made by Pioneer (ex-NEC manufacturing.)

G5W 47 OHM J micro 1DT

Re: NEC Px42VM3A lost all display

Does it test at 47 ohm or nearabouts.

Re: NEC Px42VM3A lost all display

46.8 ohms

Re: NEC Px42VM3A lost all display

I am greatful for the help. I know it is difficult when you don't have the PSU in front of you.

Re: NEC Px42VM3A lost all display

the 4 white resistors that show G5W 4.7 ohm Micro 1DT are reading only 3.6
these are up by the 1500uf 200V cap
