Re: LG RT-42P245V-Band of pink

The PDP (plasma) panel has gone bad and need to be replaced. This is not a user serviceable part and cost about 1/3 of buying a new unit plus the cost of labor for a two-man job. I would hope that this unit was purchased less than 1 year as warranty for parts and labor is 1 year. If not I do hope you purchased an extended warranty or paid it with a MasterCard (some MC card provider extends the warranty by another year). Cost of repair for flat screen TVs are high so it really a wise investment to purchase extended warranty. Fixya offers extended warranty on your future electronics purchase. Hope this helps.

Black vertical band on tv screen

Actually I am not sure about this one, but I like to suggest to leave the unit running for at least 24 hours and see what happens. Going by the amount of time it has not being used it is hard to tell what actually occurs, the advice is to leave it on standby for any period of time. See what happens anyway, you can't do anymore damage than you already got can you? Else, keep switching it on and off, it may clear it that way. If you are able get a update on-line, re-program you tv it worked for my Samsung 39 inch. Good Luck

Hi have a samsung 42 inch plasma, all of a sudden it has a band 20cm wide of dotted lines going across the whole screen, some channels or when playstation in use the band gets wider, does not seem to...

if the band is horizontal your tv has bad y-buffer board. Usually there are 2 buffer boards- top and bottom. if the problem is in the top half of the screen replace the top board, otherwise replace bottom board.
but better to replace both a the same time.

if the tv has a vertical lines from top to bottom it may have bad plasma panel and can be considered as not economical to repair.

How do I correct pink and green bands accross HP-R4252 Plasma TV

First of all try, changing the input device to some other and see whether you see the same problem. Then connect your present input to a different TV and see. If you feel the input is ok, and it is a problem in the display, this is a case to be handled by a qualified service technician.

Panasonic TC-P42S2 .. Transparent 2 inch wide vertical discoloration on panasonic 42 inch plasma, very left of the screen.

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.

Im pretty sure its not the television. You are getting interference from either through your cable box or your electric in the house. Possible bad dimmer switch.
