31'sanyo tv analog has a white horizonal line thru it


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.

An experienced tech can troubleshoot the set, and determine and service the fault.

This is most likely a scan amp, and or power supply failure. You will have to bring the set in for service.

TV NOT WORKING


I don't know if you are saying that you are not getting a screen or that you are not getting picture. If you are not getting picture but have light on screen, try autosearching, I mean tuning, if you are not getting any light on the screen your tv is dead, you should get it repaired.

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!
