I have a grey discolored horizontal rectangle on the screen the tv is only 18 months old. Can anyone give me a suggetion?

Your panel is bad.

Hello
The screen voltage to screen grid of the CRT is above than normal. Try to adjust it by adusting screen pot meter, can be located on its LOT.

probabally a dust spot on the mirror or the lcd mini panels inside the optical engine.
must be dissembeled to clean.
not for the faint of heart.

I was just watching TV and all of a sudden the screen minimized down to a single green line spanning across the screen horizontally. The label in the back says it was made in 1996 so it is an old tv. Can anyone help?

Hi

maybe your horizontal yoke is defective..

Thanks!

This should be repairable. It may be the LVDS Cable or the Main board problem. The only other problem is the T-Con Board.

Replaced vertical IC ( la78041 ??>.. Or La78040 ). Look for born resistor beside IC. Replaced capacitor 100uf 35V too!!! Good luck !!

This is Sony's way of telling you that there is a short in you set.Probably the horizontal deflection circuit.(Horizontal output transistor shorted??). Also any other short. You need to take it to a techincian and have it checked out. It would be wise to get an estimate! Stargazer

yOU ARE HAVING A PROBLEM IN HORIZONTAL CIRCUIT OR IN YOUR POWER SUPPLY kindlyu take your T.V tO A QUALIFIED TECH to repair it.ypur problem could be a faulty capacitor ,flyback or horizontal output transistor.

adjust your screen at the back of tv flyback down you see the fucos and screen adjust the sreen ok
