Three inch shadow running down on right side of screen

My tv has a yellow tint on it it is a 60 inch hitachi.

sounds like a magnetic field near your screen

needs a convergence board repair, not too hard to fix if you are handy with a soldering iron.

get the 2 convergence chips for this model @ partsstore.com

turning off the main can be very harmful to rear projectors if you dont wait for the cooling off period, for instance when you turn off the tv from the remote, the fans inside are still on in order to dissipate the heat given out by the lamp. as a result some of the lens inside the engine may have burns-in caused by excess of heat.thus leading to shadows on the screen.

hope this helps

please rate me!

replace light tunnel = use service manual for procedure....T.

You have 2 distinct problems that should be addressed separately. Please repost the Samsung problem. I will address the Sony problem here.

If the "shadow" makes the picture seem somewhat of a 3D one, the problem is with the convergence circuit. This could be as simple as bad connections on the pins of the convergence ICs or defective ICs. If you can solder and would like to attempt the repair, update this and I'll provide more details and instructions.

Is it an LCD or DLP? The Model below suggests it is an DLP. Sounds as if you have the dreaded light tunnel collapse common to all LG DLP TV's. Inside the light engine there is a square tube made up of four mirrors. These mirrors deform and crack with the heat of the lamp. They fall down over the light aperture and cause a shadow of varying degrees. It is fixable now at a realistic price ( used to have to replace engine) as LG have made the parts available. It would take a competent tech around three hours to complete or if you are technically minded you could do it yourself. I hope this helps. Good Luck.

yes sounds like a convegence issue.

Took mine to a repair shop and they said there was an issue with the line something? circuit board. Quoted me 225 parts 450 parts+labor. Mine was a red tinted screen.
