Re: Panasonic TH-50PZ77U - vertical lines

If this should not do the trick, what is best way to diagnose which component is at fault? Could the TV's internal self-test yield an answer or will I need to call a service tech? Apologies if you have addressed this elsewhere on forum but I could not find another Panasonic post with 1/2 vertical line issue such as this. I intend to tackle this over the wknd and want to be properly prepared and informed. Feel free to direct to similar thread so I do not take up too much of your time. Thanks again!

Re: Panasonic TH-50PZ77U - vertical lines

Tom66 - would I remove/reconnect the ribbon connectors to see if that fixes the issue?

We recently began to see vertical lines - approx 2 inches wide - that only appear on the upper half of the screen in the right hand corner. Initially there was only 1 line, now there is the beginning of a 2nd one. Both appear to possibly be in the same quadrant - C1 Buffer - but 2nd one could be in the C2 Buffer area I cannot be certain.

These lines are visible on all inputs Cable, DVR, Roku but they are not always present. They can be visible at initial start-up (or not) then dissappear after awhile, then come back intermittantly. For example, last night we watched a cable movie...

Re: New Members - please post your introductions here

Like many on this thread, I found my way here via a google search on plasma TV issues. I am a DIY fix-it yorself kind of guy with a background in Mech Engg so with a bit of info and insight, I always think I can fix things and sometimes I am actually right! Hopefully this is one of those times...
