I have a white vertical line on my screen. I have a picture but white line is there in the middle of the screen. I have satellite service and they suggested getting new cable wires, any suggestions before I buy this stuff? I can see movies such as dvd's and VHS tapes on the TV without the line, line is there only when the satellite service is on.

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.
The vertical hold keeps a normal picture from rolling either up or down. You don't have a normal picture (raster) here.
The problem you are having is a vertical deflection problem. The screen is being compressed to a thin white line. It's probably a defective vertical output module or transistor. This part is not too expensive. Less likely would be a vertical deflection coil, which would be more expensive because its usually glued to the picture tube and harder to replace.
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.

have a Mitsubishi TV 1993. Model CS-35301. The problem is that there is a white line that is running through a blank screen. The sound is fine just no picture. Have you heard of "Vertical Collapse?"
I would love to save the TV.
nothing to worry just minimise brightness to avoid screen burn.
means one bright hor.line in the middle of screen.
this problem can be solved
1 check vertical yoke connector or wire loose
2 check supply to vertical section which normally comes from EHT transformer
check components in vertical section or print loose
If you have a picture but the top is folded over, your vertical IC is probably good and you need to replace the pump-up capacitor next to the IC. When the pump-up cap (typically a 47 or 100uF 35V cap) is open then the picture will have white lines and foldover at the top. The typical vertical output IC is the LA7838, but I am not familiar with exactly which output IC your set uses.
The verticle output iC or the b+ feed is going bad. To fix it your gonna need a multimeter and experience working with tv. Now to its worth??? do you like the set? Does it have all the fetures and fuctions that you liokeand how good is the picture? It shount cost ya more the 125 to 150 for this repair. Good Luck
sounds like you have a vertical sweep problem. Where the fault lies cpuld be the vertical output IC the verticle b+ feed, could be the capacitors in the vertical circuit?? Your gonna need to troubleshoot thr vrtical circuit if your not a tech thin my advise is to take the set to a pro for sn est. Good Luck
