White horizontal lines on top of screen


Replace all the electrolytic capacitors in the vertical output section circuit. There will be 5 or 6 of them. Replace the at one time. The fault you see is technically called " vertical retrace lies".

On my RCA truflat tv there are solid white horizontal lines going across the top 5 inches of the screen? Do i need to get it repaired or is it a simple problem?


Hello
Your TVs vertical output section has the trouble. Electrolytic capacitors in that section, 8 numbers the most, should be replaced with new capacitors. Iit won't cost more. OK.

You have a vertical output circuit problem. This was common for Philips' sets. Have a repair shop check it out. Should not be too expensive to repair.

White lines accross top of screen on our 27 inch Toshiba,


lcd or plasma.
are the lines solid or blurred. do they have sharp edges.
You may have a memory problem with the display which can only be repaired by factory trained technicians, or a brave soul willing to find parts on ebay.

Look for bad capacitors in the vertical deflection amp, and in the pin amp sections. This is common on most of these types of TV sets.

The caps tend to go high in ESR with age. It is best to use an ESR meter to find the bad caps. It will be a lot faster than workign out waveforms with a scope.

Wikipedia explanation about capacitor ESR:

It sounds like a vertical deflection problem. You mentioned you had a white HORIZONTAL LINE in the middle of the screen. If this line runs from left to right across the screen it's in Verticla deflection. If it runs from top to bottom, it's in Horizontal deflection. I am assuming the problem is a Vertical deflaecion problem. The repairs necessary are most likley to replace the vertical capacitors or the verticla deflection chip.
Good Luck

sound like you have 1 or a couple of leaky/bad capacitors in the tv's vertical circuit, typically, there sould be 5 to 10 caps. in all, but you just need 1 bad one to cause your problem. good luck.
