Sanyo 31'' Standard Def CRT TV


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.

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.

Sanyo ds31590 picture's very dark and red


sounds to me that your picture tube needs rejuvenated.
You will need to get it done by a tech.
mechanical doesn't mean a thing when it comes to electronics.
Mechanics when working on electronics, end up costing more damage when you end up taking it to a tech.

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!
