Question about Sanyo DS31590 31" TV
Chances are real good that your picture is showing its age. There are three color beams in the neck of the picture tube. When these electrodes are operating correctly the will produce an arc, that will produce the proper voltage for color correction. Much like the spark plugs in your car. When you have a fouled spark plug, you replace it. In the case of a TV, replacing the tube is the best way to correct the picture you are looking for. It would be to costly to do this of course. Another option is to rejuvenate the picture tube. Once again, rejuvenating the picture is last resort. Customers must be warned that rejuvenating may work or even in some cases destroy the picture tube. I want to remind you as well, the symptoms you describe will over work the main board as well. This TV is not feasible for repair. Thanks for asking and show a few hands of support!
