If this tv vertical colors lines problems happen by itself,tv problems not causes by u or an object by hitting forces to the tv LCD screen panel itself.The tv board that call the T-CON board it is dead,this board sit in the bottom in the middle of the LCD screen panel.Must be replaced the T-CON board to solve tv vertical colored vertical lines.Tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish T-CON board for the replacement.If causing by u or an object by hitting forces it to the LCD screen panel itself.The tv not worth a whole tv anymore,because by replacing the tv LCD screen panel will cost the same as a new tv.
The PDP ( plasma display panel) is defect.You can look for badly soldered SMD resistors on the COF panels wich are located at the bottom of the screen.
Beware,the flatcables wich the resistors are located on are verry fragile!
If its a LCD projection TV (such as Sony Wega, Hitachi, Epson, Philips,
and some Panasonic, some Mitsubishi), and the green image is in the whole
screen or just one part as a blob or a line. Is most probably that one of your
LCD Color Filters is damaged (burned out or starting to get busted), I don’t
know if you can just replace the color filter, I believe you need to
change the whole light engine system or the optical block. There are some
places around, I found some on ebay but you should definitely try on
discountdashmerchantdotcom their price range $260.00 - $330.00
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.
I had the same thing happen to me this morning. I turned on the TV and it had colored vertical lines through the whole screen. I called Sony and they had me unplug the TV for about 15 minutes. This solved the problem. They said the boards just needed to be reset. It fixed the problem and I am happy with my Sony once again.
