This is a fault in the vertical circuit. It can be either a bad solder connection of the vertical IC or a defective IC. If you can solder, you can fix this yourself. Open up the back and locate teh vertical IC. It willbe a small flat IC attached to a heat sink and be marked LA7841. Resolder the pins first. If that fails to resolve the problem, replace the IC. Please note that there may be capacitors in the circuit that need to be changes as well, but without the chip working, it will be difficult to determine which ones. Update this once the IC has been resoldered or replaced with the results and we'll continue if necessary.

White line in middle of screen on a cx32h60 toshiba tv


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.

This is a vertical problem that can be as simple as poor connections at the vertical IC or a defective IC. If you can solder, you should be able to fix this yourself. Realize that there are potentially dangerous high voltages present inside hte set even when unplugged. If you wish to attempt this repair, please update this and confirm your model number as DS31590 and I'll supply additional details and instructions.

There is a failure in the vertical amp section. This can be the main output IC, or any of the support components in this area.

Tv not working


this symptom, sometimes called the tube light effect, it is characterised by a bright thin horizontal line across the middle of the screen. this symptom is caused by a breakdown in the vertical deflection circuit. hence maybe the trouble maybe in the vertical oscillator, amplifier or output circuits. but if all i have said is not clear to you, better bring it to a qualified tv technician. good luck!
