Viore pdp42v18ha

[ta630]

Okay people I have been through tom66 troubleshooting for plasma tv
Will post a picture if needed but I have no voltage on the vs side of the power supply
My question is I have a picture that is viewable at night but very dim in the day
I had to turn the brightness down to even view the picture
Would a bad power supply cause this
Viore pdp42v18ha
I belive its a lg power supply
Thanks for the help

1st you will need to verify your SMPS voltages to the sticker in found on the inside of the panel.

I suspect this is a bad X/Z board as the picture looks very washed out and faded.

vs voltage was a touch low at 185
now set as per sticker at 186
vd voltage spot on at 60
5v is showing 4 volts
The reason for not showing any voltage last night
Replace batteries in multimeter
Thanks Steve
