Question about Sony Grand WEGA KDF-42WE655 42" Rear Projection HDTV

1 Answer

Vertical green lines

I have experienced very distinct vertical green lines that go from the top of the sceen down about 2/3rds and from the right to about 2/3rds of the entire screen. I will stay that way for sometimes several days and then one time when you turn it on they are gone. Months later they will reappear for various lenghts of time. The lines will stay there no matter how many times you turn the set on or off. This will effect both programming and DVD's so I do not believe that it has anything to do with the incoming cable connection.

It sounds like th green LCD panel laminations or bonding has separated and this is causing your green lines. The optical block would have to be replaced to solve the problem.

I have green arched =lines r=going through my screen How do I fix this?


If the lines are slanted up from left to right and spaced several inches apart, you are seeing the vertical retrace line. In that case, you may want to turn down the screen voltage on the green CRT. The instructions for making this adjustment are given in the service manual.

It should take just a small tweak to hide the retrace line. If adjusting the screen voltage won't do the job, check for a leaky or improperly biased CRT driver transistor, then compare the video waveforms with one of the other CRTs to make sure the voltage at the vertical blanking interval is correct.

In the worst case, there is a problem with the CRT. This is generally accompanied by occasional arcing (bright green flash or the set shuts down with an error code flashing on the power light).

The vertical green convergence adjustment is broken


Either your convergence ic's are bad or the convergence digital module ( if your model has one ) . I would have it looked at by a service company.

I believe its the vertical output IC. Diodes would tend to blow fuses . I would replace the vertical output and see if that takes care of the problem.

Screen distortion


Is it a clean vertical line or a fuzzy vertical line? It could be as simple as a cleaning.

My tv has this lines that bend over the front top of the screen and when an object moves through the lines the image appers from the the top of where the line begins...and the tv goes black every once and...


This sounds like a vertical deflection fault. There are some components that are failing in the vertical deflection area that are starting to fail. It is very common in many of the sets that there are electrolytic capacitors in the vertical amp section that are gong out of specifications.

When you have at the top or the bottom of the screen where the vertical axis is compressed, and the picture in the compressed area looks like it is inverted and going over on itself, this is called "vertical fold-over".

An experienced TV service technician should be able to service this for you.

Picture shows only about a 2-3" blue,green,or red vertical line down the middle


If your seeing vertical line across the screen you need to check the components in the vertical stage as well as the vertical IC could be bad, or the yoke could open.
Also check if any voltage reaching the vertical stage.

Good luck.

Was this help full.
