Re: Panasonic TH-42PZ77U blue clouding on white screen

Just a follow up. After a few heat cycles blue clouding is back. I may experiment a little more as I wait for a good sale on another TV. My knowledge of plasma troubleshooting is very limited. I did look up hours on set. 29000+.

Thanks for the reply. Yes, one mistake with the solder iron had put me in days of confusion. The SOS System Shutdown saved me from damaging the D board.

Re: Panasonic TH-42PZ77U blue clouding on white screen

I'm baack; After multiple days of trying to figure out why changing out the larger 56uf and 68uf capacitors on the D and DG boards would cause a SOS code I found the problem. A minuscule drop of solder welded itself between 2 terminals on the FL304 feedback capacitor on the D board. I decided to change the caps on the D board, with nothing to loose, because unplugging the DG board made no difference to picture quality. Changed out the DG board as well because I had it out. As of now the bluing is gone so I've made adjustments...

Thanks, I'll try the service menu first so I don't have to remove a pile of screws to get the cover off again. I did check the VSUS voltage on the board a few days ago and it matched the ratings on the sticker label so I left it as is.
I did read this sticky on plasma's but it didn't seem to list my issue. [url]https://www.badcaps.net/forum/showthread.php?t=18542&[/url]Re: Panasonic TH-42PZ77U blue cloudi...pile of screws

Re: Panasonic TH-42PZ77U blue clouding on white screen

Went to test screen mode. White screen shows blueing in center....

Hi, I just started having an issue with my plasma. If watching say a hockey game with white ice I get floating blue tinting on the white. I also noticed on peoples faces there are grey patches over their skin tones. I can also see the front panel grid board outlines in the patch areas. I'm wondering if it's the D board as the issue is more pronounced in the center of panel but covers the whole screen depending on scene.
The pictures attached don't really show the intensity of what I see.

Thanks...
