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 off!

A lot of these sets have a problem where a "filter cap" on the board in the power supply opens---Usually location is "C925 or C926" and it will be a 1000 mfd @ 25 or 35 volts.

Let me know if you can locate it--if so---unsolder the two leads (one marked with a plus and the other with a minus--positive and negative) and replace it----$4.00 part.

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.

Very dark picture on TV

Try restoring all factory settings. On your remote, press the reset button twice. If that doesn't correct it, then you'll probably need a repair technician. For more info, consult your owners manual, which is also available at

Sanyo T.V.

take the back off the tv and where the power cord hooks into the tv check the fuse there on the board if this isnt blown then you are probably looking at a power supply problem look at the board for anything that looks black and burnt or dark brown spots on the board. this will tell you where the problem is if it has any. but it just might be the fuse.
