Re: I think my plasma has bad caps

I changed the D-Board and problem solved. Thanks to all with the diagnostic help and recommendations.

Re: I think my plasma has bad caps

I had been in the service menu but didnt realize or have documentation to the test patterns. I ran through them all and NTF (no trouble found) as all test signals displayed properly. That is good - the tv isnt in too bad of shape but not helpful in diagnosing the issue.

Giving further thought to the D-Board diagram which you provided, where one micro controls one half of the display and the other micro controls the other half does give further credibility to the D-Board as the faulty board.

Re: I think my plasma has bad caps

I did get into the service mode today and was going to try the mirror functions (horizontal and vertical) to see if the lines moved to the other locations of the TV. Something very interesting happened, when the service menu came on the screen (it just so happened to be in the same quadrant of the screen but not overlapping location) the red, blue, & green lines disappeared. It seemed like the picture was lower resolution while the service menu was displayed but no lines. I flipped it back and forth via the mirror function and the display looked...

Has anyone seen a failure like the attached? My Panasonic Plasma TC-P65VT25 started to exhibit this behavior this week. Turn the TV on and the display looks fine. After about 15 mins, these red, blue, and green lines start to appear a few mm high and then grow to about 2.5 inches and remain that way until the tv is shut down and cools off. The lines are always at the same location: bottom of the top left quadrant of the tv.

Some folks have said look at the A board while others have suggested the SS board (X systain board). The problem does seem to have some analog (capacitor) logic...
