Question about Sanyo DS20425 20" TV
I can press the power button three times and the TV comes on and
quickly turns off. If I unplug the TV for 5-10 seconds, I can then turn
it on three times as above. This is repeatable.
The manual's "Helpful Hints" states -
1. Problem: TV turns off automatically
2. Check these conditions: Check signal (Cable/Ant.) connections; Power surge feature
3. Try these solutions: Press POWER key; The sleep button may have been set; Unplug TV momentarily
Please note that is a Sanyo DS20424, not a DS20425.

the problem is we have no cable-none at all. The tv is used only for playing DVD's. solution check dvd to tv wire or socket if it is ok then play dvd in another tv if it works fine then problem in tv. for that check tv tuner & its circuit for loose. check tuner itself

Ok, cable connected is good. Can you move tv to another connection or run another cable from a working source. Maybe go into setup of tv and check input.

Solution to the won't turn on or turns on and turns off in 3 seconds thing...as my Ds24425 did.
First thing is very important...unplug the TV and let it set for 24 hours before you proceed.
The voltages inside a TV are EXTREMELY HIGH and LETHAL....so proceed with caution!
Place the set face down on a towel on a table and remove the back cover....hex screws around the perimeter and 1 phillips screw near the inputs.
The main board will slide up and out. unplug the degausing coil "white plug with two wires" and the speakers connector. This will make it easier to turn the board and take a look.
What I found with mine was a bad electrolytic capacitor. You can identify I bad cap "capacitor" by examining the tops of each one for bulging or signs of overheating "melted or bubbled plastic covering." The cap in question was C626 with a value of 1000uf, 16volt. I replaced with a 1000uf, 35volt and it works perfectly. The cap is located about center of the board. Carefully unsolder the cap and remove, make sure to install the new cap with the proper polarity...the board is marked with a dot indicating the negative lead of the cap.
Be sure to reattach the white plug and speakers connector and slide the board back into the plastic grooves. Then replace the back cover and test. Good luck! ...Daddio
