Expanded screen


If it only does it via the coax or cable fitting it may not be the set.

Does it do the same thing when playing a DVD etc?

If problem is on all inputs it is a deflection problem in the set which for whatever reason has over scanned the picture to tall---it suggests a problem in the Vertical deflection circuit of the set (top to bottom is vertical deflection).

Only have one horozontal line across mid screen


Horizontal line shows problem in Vertical Deflection area of TV, please check Vertical Output IC and its voltage supply. You didn't mention model and brand name so I gave you general information for that problem.

My tv is all blackexcept a wihite line through it and no sound


If the line is going across the TV the vertical deflection circuit needs repair. If its going from top to bottom the horizontal circuits are needing repair. Please post your model number and I will be better equiped to let you know which part is likely at fault.

You have incomplete vertical deflection at bottom of screen. Replace C155(2.2uf@16v) on video/deflection assy. Use part number ACH1131

If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. This should not be an expensive job at most repair shops. Could be something as simple as cracked, cold, defective solder joints around and near the vertical output chip, could be a faulty chip and other components in and around the vertical deflection circuitry, or a faulty vertical drive signal from the jungle circuits, or worst case a faulty deflection yoke. Take your television to a shop right away for a proper and safe repair. Do not keep the television looking at the red horizontal line.... you can easily damage or burn the CRT phosphors. Good luck
