Replace the power supply.

It sounds that the main system control memory IC is faulty. Replace it and check. This is a very cheap to buy IC. Eventhough its cost and size is small, the function of it when the set is switched ON, is great. It is a very small IC, having only 8 solder terminals. If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window
