Fujitsu 63" PlasmaVision W HELP PLEASE

[MaCJaX]

Hello all,

I have 2 63" Fujitsu Plasma displays model P63XHA30WS. Both have similar issues. One of them will work perfectly for a few days or so then will display blue vertical pin-strip lines about 1 1/2" apart and about 1/8" thick. They will come and go depending on the image displayed and will last anywhere from 20 minutes to the rest of the day. They do not go away after a power down and might come still be there the next day.

The other plasma has the same blue line but only one half way down the screen and it's there all the time.

I was thinking the the first one has a bad capactior which seems to discharge after time causing the lines and then recharging, causing the lines to disapear. Do you guys think I need a new power supply board ? Any ideas would be greatly appreciated !! Thanks !!!
