SOURCE: CS- 40503 No Power

There is no external reset, and if the set is completely dead (not even a click when the power button is pressed) then there is probably an open main fuse or defective stand-by power supply. If the main fuse is blown then there is usually a heavy short in the main power supply, and either way the set should be looked at by someone with experience in Mitsubishi sets.

Mitsubishi CS-40503 TV previously had discoloration in the corners and lines at the top of the screen. Now I have no picture at all. Is it worth trying to fix?

Mitsubishi CS-40503 shuts off while watching.


Could be any number of things, none of them easy to diagnose. Unless your a TV repairman it's probably not worth fixing. It will cost tou more in repairs than a new TV.
