Hi,
Well being an engineer i think there is a technical fault in your TV so you certainly need a mechanic. Please call the service center. They will fix your problem immediately.
I hope it will help you.
Regards!

If these lines are thin you have a picture tube problem on crt board, if they start at the top you have a vertical blinking problem.

That depends on the model.

On Toshiba this problem is typically related to hyperboard fault: Toshiba Rear Projection HDTV wavy lines

On Sony it is often a fault on digital board.

On other models it is often a fault with video chipset or in some case it can be a light engine faulty.

Ring the support phone number listed on the owner manual to get a quote on an eventual repair.

    If this is a CRT then you do not fix the problem by replacing a part. Traditional CRT TVs have many functions on same board, and on a CRT this is a vertical deflection problem, probably because a capacitor or a component on main board has blown or is malfunctioning. The job must be done by a technician.

32 INCH ZENITH PICTURE IN PICTURE ABOUT 15 YEARS OLD.PICTURE DISAPPEARED AND ONLY HAVE A THIN WHITE LINE RUNNING ACROSS THE SCREEN.THE SOUND STILL WORKS FINE. IS IT WORTHWHILE GETTING IT REPAIRED ??


When CRT TV's show only a white/bright line horizonatlly It is a failure of the flyback Transformer. Not all that costly to repair. Your old TV will probably still be working when all the latest plasmas and rear projections have been laid to rest. Fancy junk TV's dont get any better programs than those old reliable ones

Please rate my help++++Thanks for using FRIXYA

Hey there I think the problem is coming from your LCD chips not your bulb, the bulb has nothing to do with the color or skwiggly lines it just shoots out white light,your LCD chips are burnt and the problem will not stop by changing your light bulb you need to replace the OPTICAL BLOCK the skwiggly line will just get worst with time
hope this helps
