RCA Plazma TV.
RCA Plazma, under warranty, Model # P42WED33, unit has vertical bars
running down the right hand side of the screen, about 1/3 of the screen has lines that can be seen only on dark scenes, & they are in threes, & some by themselves. Also, some tiny noise specs throughout the pix on analog tuner, as qwell as some slight burn-in. This is practically brand new. First one I have seen. Are parts even available for these? I read that LCD, & some other units, have no parts, just replacement. Has anyone worked on this nuit? Thanks, Dani. |

Screen burn is permanent, the bars are likely bad drivers bonded to the panel which also means the set is not economical to repair if that's the issue. |

Plasma screen burn
I have had some success minimizing mild cases of screen burn-in on Plasma screens by displaying a 100% APL white screen from my video signal generator for several hours.... after two or three sessions the screen burn-in may all but disappear in some cases..... I agree with James Sweet though.... screen burn is permanent in all but very mild cases.
