Panasonic TX-P50GT30B screen problems

[marekk]

Hi,

After repair of the SC board I noticed very thin part of the screen at the top which shows blue sparkles. the area where this sparkles does appear is around 10 pixel lines tick and runs through most of the screen length. On top of that there is quite significant screen burn on the right side of the screen.
Is that repairable?
I would really appreciate any advice with this problem.

Best regards
Mark

Ok, blue sparkles I have solved partialy by dropping the VSUS to 209V, I hope it's not too low, stil this part of the screen is sligtly brighter than rest.

what's vsus set to in serv menu, hi or lo? from memory 204V lo, 209 hi. I think we've seen this before, generally the Vsus is factory set and sealed at the P board and then the A board controls it from there

VSUS in service mode is LOW, I couldn't even change it to HIGH

you can, just need to read the service manual procedure on how to do it.
