It sound to me like a defective light engine. If so this is a very expensive repair if you set not under warranty or a service contract. This could have been damaged by a power surge.

SOURCE: Horizontal Lines On Screen

horizontal lines = horizontal sync off . mitsbishi always seemed to have this problem .. on the older sets I would take the back off and inside deep on the board i would adjust a pot and sync it right .... and never had a recall, maybe your newer model has this too .. this little control,

but its a horizontal sync problem.

if no change the horizontal processing ic.

SOURCE: Sony KF50WE610 Vertical Blue Lines Across Screen

the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.
good luck!

Why my 42" sanyo DP42841 HDTV LCD SCREEN GOES BLACK ON THE LEFT SIDE?


That sounds like a faulty LCD panel tab. The only true fix is to replace the screen. This usually isn't cost effective.

Sanyo lcd tv picture has stopped working


Could be several things going on but the unit will need to be diagnosed to be sure. I would start with checking the t-con/LCD panel ribbon connections. Outside of that could be a defective t-con or LCD panel.

Our Toshiba Regza LCD TV has developed a thin white vertical line down one side and a green horizontal line across the middle. The bottom half of the TV screen then comes and goes in muted and faded...


Hello,

All Plasma and LCD TV have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times resetting the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken . Good luck in solving the problem....

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.
