Question about Sanyo DS24425 24" TV

2 Answers

Sanyo 24" flat DS24425 suddenly turned off, won't turn on. Pressing the power button either results in no response or it turns on for a second, then turns off again. No picture. Already tried playing with cord connections and unplugging cord temporarily. Unplugging results in TV coming on for a second. After a few times of that, there is no response with the power button. What is shot? Thanks.

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

Sanyo DS24425 Intermittent Discoloration


It seems like this problem would have to be with the picture tube itself, although I have never run into this symptom in over 30 years of servicing TV's. If the CRT is still in warranty I would get it checked out. Otherwise it probably not be worth repairing. If you end up replacing the set, check out the Toshiba 24" model. I have had good luck with that model in the past.
