The vertical sweep output is absent. Check its vertical output section circuit for the fault. Check all the solder terminals of that section, and resolder them by applying a little more solder. Take special care to the solder terminals of the vertical output IC. If these do not help you, check and replace the vertical output IC.
If there is a white line across the screen, the vertical output section of your TV is faulty. If the line is vertical at the middle of the screen, horizontal deflection yoke doesn't get sweep signal. You haven't mentioned about the full mode number of your RCA TV. Therefore I can only give you this much hint. OK.
You would need to replace the flyback on this and your looking aroung $65 parts and $85 labor to shore this problem up. We can recommend you a repair shop or you can purchase a new TV its all up to you
Middle going across the screen from left to right??
This unit is plagued with bad solder connections in the comb filter board and flatpack underneath the comb filter board. These connections can cause any odd number of problems in video display. If it is that it's not expensive - virtually no parts. If it's a single line across the screen could also be the vertical circuit involved.
My suggestion is to have it estimated at a reputable shop and take it to them rather than the more expensive pu/del charges.
If you would like go to http://www.nesda.com/locator/state_search.php and locate a servicer from there. Kinda like going to the AMA to find a doctor...
Hope this helps!
It has a problem in the vertical sweep circuit that puts a nonlinearity
in its output and you see the glitch in the normally gradual sweep as a
line. Since a hit upside the set seems to help, you should just
resolder the whole vertical circuit area (doesn't take long) and see if
that cures it. If not, start replacing the electrolytic
capacitors in that area.
Hope Ya Fix It!
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.

im pretty sure you cant fix that you probably need to buy a new one.. i know that because my somputer has a white line that runs right down that middle, not all the time but sometimes. my father looked into fixing it and he found out that you have to buy a brand new screen or tower or something like that.
never heard of so called card myself but ,is the line your talking about from top to bottom or from side to side in the middle?straight across middle is called horizional which means vertical problem so you have either bad capacitors 35uf 100v ,1uf 50v, or bad vertical output ic.
