2 Answers

Sanyo 24 in flat screen model DS24425 Screen slowly goes fussy and slowly goes black , a slight tap on the rear left side brings the picture back to good screen,for a few minutes or a couple of hours no set pattern of time. When one turns the set on again some times come on clear other times very dul or black, slight tap and good screen. Sounds /act like a bad solder connection but which one do you have a wiring diagram or know where to get one? Thank you

    while moving the TV ,I lifted the front right hand corner and got a good picture... so I put some folded up cardboard, under the front right hand corner and this worked for about a year. Will have to take it apart and seeif I can find the bad connection,suspect it is near the rear left where the external connections are entering the unit.

Hello
Your flat panel TVs picture tube base board has soldering loose contact with it. Just unplug your TV from AC mains socket, and open it. Pull out the picture tube base card from the picture tube neck. Pull it out straight, no shake must be there, as it will damage its connecting pins.
Normally, loose sodering are very difficult to loacate, as they will be quite micrscopic in size. Just resolder all the suspected loose sodering point on that board, by applying a little more solder. This will solve your TVs problem. OK.

My Sanyo DS24425 tv is showing red retrace lines across the screen. The picture sometimes fades out and is replaced by these red lines. Can the tv be fixed?


yes it can be fixed. it needs replacement of a component that heats up and often due to heat it loses solid welded connection, if welded properly it returns back to normal, if not it needs replacement with substitute or comparable capacitor item removed Id codes on it

You have a bad connection to the panel or bad caps on the boards. Not something for the DIY'er. High voltages in plasma sets.

My Sanyo DS24425 24 inch screen moves slightly to the left and stays there. its very frustrating because i play games on that tellie and cant see part. it's not parted halfway though. its like one a couple...


The problem can be corrected by only qualified technician. There is what is called the service man's menu which can only be accessed by a partciular code in service manual for that particular TV. Your local service technician should be able to locate the the manual and then perform what is caller a horizontal centering adjustment. In today's tv's there are no alalog controls for easy adjustment, it all done with eprom ic which allows the manufacturer to use the same chasis for many different picture tube sizes. If you could get manual. and have basic computer skills , you could probably do it yourself. You might try ordering the maual from Tritrinics/Cititrinix 1-800-638-3328. Scrivitron

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.
