What should i do,model number below has vertical lines on half of the screen, any suggestions?

If they are blurry lines, likely you have a problem with heat damaging the diffuser plate behind the LCD. Unfortunately, there is no fix to this other than to replace the screen, which is as much as the same TV used. It's usually caused from the vents in the back of the tv getting clogged with dust/debris/smoke and the power inverter overheats. It causes the screen to develop a line on one side of the screen, then it starts to look like the screen was washed with something and you get black streaks running from the top which usually is accompanied by a darkened blurry "cloud".

How to fix Toshiba Regza LCD TV when half the screen with vertical streaks?

hi this fault sounds like a bad tab/ribbon fault, at top of the tv are ribbons connector to the screen, when one is faulty the heat makes them flex causing this fault, you can bond the ribbon down with a bit of rubber to stop it flexing, but this not a permanent repair as it is a screen fault. hope it helps

My son wiped a baby wipe across my LCD tv and now there is a purple streak across the tv I have tried wiping it with a wet soft cloth but it didnt do anything any suggestions?

Did the baby wipe contain alcohol? because LCD screens are sensitive to harsh chemicals. they have layers so this possibly damaged them.
so i think you can save it if you go to a tv repair man or get a new.

My son took a baby wipe to the LCD tv screen and now there is a purple streak I tried a damp soft cloth but that didn't work any suggestions how to clean the baby wipe off?

Try a 50/50 solution of water/rubbing alcohol and a micofiber cloth. DO NOT SPRAY THE SOLUTION ON THE SCREEN ITSELF but on the cloth then wipe down the screen. I hope the screen isn't damaged !!!

Some one sprayed something on my flat screen tv and now it has streaks

It could possibly be stained and cleaning will not help. Please run out to the electronics store and purchase an LCD cleaner or LCD cleaner wipes. Hope you can still fix this. Thanks for asking and show all hands of support!

I have only had this tv for 2 years. Sony Bravia 32". Black streak going through top of screen & light streaks going vertically down the screen. Also happening on the same day this happened. ...

sound like inverter is going bad.

if you got streaks might have gotten hit by something.

also power supply might be going bad. if you have not clean it of dust, overheating could be the culprit.

good luck
