I just bought a panasonic TH-42PX80B plasma TV, but I don't get a full screen. I get a vertical black band on the side. Is it a mecanical problem and should I bring it back to the shop or is it something I can fix ? Many thanks,

Got a dead short if it takes the fuse instantly when plugged in and or turned on.

Price the power supply board which if replaced ought to fix the set.

Fixed mine, myself! Black 3 inch vertical band (stripe) appeared after a cros country move on our PC-T50G10. Occasionally we would see white band with multicolored pixel width stripes. Took the risk of taking off the back to see if I could see anything. Found places on sides and bottoms where plastic like 2" flat cables could be seen. Guesstimated where the band was and found that I could flip down a black cover on one end of the cable. Tried to pull it, gently. Mistake. Realized it wouldn't one out like computer hard drive cables, so I took out the screws holding the plate on the other end (it's only an inch long). That allowed me remove the cable. Took it out, cleared away dust, put t back and closed the black over. It worked! Put the screws back in, back on and... we are happy (although I do have four extra screws!). Just be gentle.

If you let me know in which location of the screen is located I can assist with the possible cause since the vertical line can be caused by different items based on where its located on the Screen such as center of screen, or far right side or midle of the right half side of the screen. Reply to this same post with where the line is located and I will assist you with it.

There is a good chance that the plasma panle may have become faulty, but another cause of this is a faulty X-SUS Printed Circuit Board or a Y-SUS Pinted Circuit Board, they are labelled which is which on the Circuit Board themselves. Replacing both of these may solve the problem. Good Luck.

take it apart and reseat connectors on bottom buffer boards if not may need to replace buffer boards on bottom of tv

chake to make sure it is hooked up right and not lose
