Shadowy horizontal lines on plasma tv

"> 2005 Dell 4200HD 42" plasma tv; tiny barely noticeable moving red dots cover screen when first turned on, they disappear then perfect picture for 30 minutes to hour or more, then after warm up shadowy horizontal vibrating lines appear across the screen, they are most noticeable in dimly lit scenes and get worse the longer the tv is on. I've checked all the connections that I can access and confirmed that it's not the cable to the tv. Is this worth fixing or time to get new tv? Many thanks!!

    Dell Plasma TV are bulky, huge and old. Dell would ask you to ship to them in California and cost over @2000. Your TV will need only a few parts (not more than $200) if you know how open stuff; handle delicate parts; and work on electronics components and diagnosing.

Fixed non moving lines usually means you have a problem in the panel display or t-con. If it is in warranty get it to a factory authorized service center. If not you can try to change the t-con and see if this fixes the problem, if not then it will be the panel it's self and will be cost prohibitive to repair.

SOURCE: I have a Sanyo 46 inch flat screen hdtv purchased

I have the same problem, my television is faded black on the left side with lines on the left top side. I have had the 46 inch unit for 1 year and 7 months. I am planning to write a demand letter to Sanyo and then taking them to small claims court woth evidence that this is a common problem with their units that they know about and is not trying to remedy. Also the Attorney general in Texas should have an interest in them (Walmart and Sanyo) selling these defective proucts in the state.

Vertical lines across my entire screen


My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.
