Question about Televison & Video

Have Westinghouse 32"LCD TV. When its very hot and humid after being on for approximately 30 minutes black, heavy vertical wavey lines appear on the screen. Sometimers I can make the lines disappear by cycling the set off and on, but the lines come back. The lines do go away after the A/C cools off the room

I have three black vertical lines on my TV screen


You can try a hard reset: Unplug TV from AC mains and remove all cables from TV. Wait about 30 minutes and replug to AC power and redo the cabling. Switch on the TV and see if it works..


Good luck...

Vertical lines appear on the screen.


It appears like there is a bad capacitor in the horizontal circuit. Try to put a fan near the ventilation trap, just for a test.
the part cost almost nothing but having someone to your house is expensive.
Your decision.

Sony KF50WE610 Vertical Blue Lines Across Screen


the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.
good luck!

Wavey lines


Sounds like your set has dried caps in the Power Supply, take it to a decent tech, its not something you should try to do yourself as dangerous voltages can still be present evn if the set is unplugged.

White vertical lines in Zenith lcd projection tv


Get price of a LCD drive board first, then call a shop to see how much they would charge to replace it. If you have already researched the price you can get a better deal. But I really wouldn't try to replace this yourself. It takes major disassembly and alot of training just to get this model taken apart and put back together. Good luck, Russmann.

Long warm up time


you have a bad capacitor in the deflection circuit.You will need some diagnosing and testing to find which one. An ESR meter will make short work of that but they are expensive meters.
