It sounds that there is a loose contact to some connection wires, the flat wires that comes in, and go out the T'Con board. Re-seat all the flat cables and check. http://electronicshelponline.blogspot.com/ Check this link too. It has screen shots to different faulty displays. Pull up older posts and compare with these images to your TVs screen, and make confirm. Remember, vertical lines can be due to a faulty LCD display screen too.
Vertical lines on your LCD usually tells you that your screen is failing. You can do a quick verfication by plugging in an external monitor - and if the external monitor looks normal, then that ought to confirm it.
Once you have vertical lines on your screen, there's no way to get rid of them - it's pretty terminal unless you're into repairing microelectronics. For replacement screens, eBay would probably be your best bet.
hi there, you do have a vertical problem, its a resistor with 100k ohms or up at vertical section, next is some capacitor with 100microfarad. try test some parts at vertical section. ty
I've had the same problem. A temporary fix that I have found is to turn up the contrast all the way (press [2nd] then hold down the up arrow) until the screen becomes mostly black. Then turn the contrast back down (press [2nd] then hold down the down arrow) until it is at a normal level. If you can get rid of all the white lines when you turn up the contrast the screen will be back to normal. Unfortunately this does not permanently fix the problem because I cannot get rid of all the lines and it seems to be getting progressively worse each time it start up the calculator.
