Question about Toshiba 36A40 36" TV
I have a flat screen toshiba with vertical green line, and looks like it appears only when the tv is warm.
This is generally the case when the Horizontal Yoke Coil is defective.A defective Hor. Deflection Coil bad is very very rare. 9 cases out of 10 it is a dry / bad solder.If you are versed in Solid State Electronics, I advise you to Unplug the TV and carefully open the back panel. There will be a Coil mounted on the neck of the Picture tube. It will have 4 connections and there will be 4 wires leading from it to the Main PCB. Check these connections - both on the Coil and on the Main PCB. If these are OK, then call in a qualified Technician.Nothing more you can do.
