Looks like Z-sustain or Vset_dn issue; pictures of the boards?

It also left shadows after the menu is on. Not sure if its the same problem.

Re: lg p's 800 fuzzy picture plasma

Vset_dn = Yrr so I'm suggesting that as a possibility.

Re: lg p's 800 fuzzy picture plasma

Y and x sustain

Re: lg p's 800 fuzzy picture plasma

Is top panel sticker saying this is a PDP50H3?

[adamp91gvm]

Re: lg p's 800 fuzzy picture plasma

Yes

[tom66]

Re: lg p's 800 fuzzy picture plasma

Great


Search 50H3.

Page 121 - Vs/Va: check these.
Page 123 - Vsc/-Vy: check these.
Page 128 - Vzbias: check it.

**USE YOUR PANEL STICKER - NOT THE ONE IN THE DOCUMENT.**

Red one end, black the other - if in doubt, see the pages I indicated.

[adamp91gvm]

Re: lg p's 800 fuzzy picture plasma

The vsc and the vy are up and down

[tom66]

Any change when adjusting them?

[adamp91gvm]

Re: lg p's 800 fuzzy picture plasma

Only in the pic slightly bit the voltage is still up and down

[tom66]

Re: lg p's 800 fuzzy picture plasma

Looks like you have a Y-sustain fault then.
