You need to replace the color crystal (frquency is 3.579545 mhz) problem is I do not know which one it is... sorry. If you have the schematics for the TV it should be easy to locate but... you don't. See if the crystals in your TV are marked with a frequency. If not, try replacing one at a time... if the problem goes away your all set, if it does not or gets worse put the old crystal back and try it in the next. Do this at your own risk and watch out for that large red wire going to the picture tube!! Even when the TV is unplugged it can kill you!

No picture only sound.


Engineers are right, you need a new LED panel., or the component that supplies the light to the screen.

Can't on and off tv


Hello Carl, check first for:
  1. AC mains voltage.
  2. Open Main line.
  3. Open TV cord.
Then we go to the TV itself,
  1. check for power switch does they feel spongy, sluggish or not operating properly.
  2. If you use a remote, check for batteries.
This is now TV power supply problem. need to open the back panel. Caution this should be done by a tech person.
  1. check the ac line from mains to power supply board.
  2. check for open fuse.
  3. check for output voltage on the main board.
If you see bulging capacitors, check for power regulator. This part of the service requires a technical person. as this point the logical next thing to do if the trouble was not found, replace the entire power board. Replacing the power board is costly. Hope you decide what is reasonable. Replace board plus labor and effort, and a possibility that the TV may not work due to poor analysis. OR call your dealer for service.

I have the Daewoo Plasma Digital Dream model dp-42sm and it had power but no picture and my dads tv expert friend looked at it said the ysus board was out. I got the part on ebay for 125 dollars with 12 dollar shipping and put it in myself very simple and the problem is fixed. Is this the same issue your having?

Broken TV


Replace the y-main board and the upper and lower buffer boards. 300.00 from Sanyo. Install them your self or get someone technically minded to do it for you. It worked for me. It's been 6 months and the t.v. is still going strong.

Power green lite wont stay on but 4-5 seconds


Have same problem. This is an e-mail sent to Daewoo. We purchased a DSJ-4710CRA/5510CRA TV about two years ago from BJ'S wholesale club. TV has been fine until about a month ago. Turned TV on and it shut down after a minute.Called local TV repair people and they came out . First call they suspected the High Voltage generator. That trip was $102.55.They ordered the part from Daewoo. Part came in and was installed. TV still did not work. That call was $115.56. They took unit to their shop for further testing. Found the Deflection board was bad. Call Daewoo to order and was told part is not available. Tried a board rebuilder and no luck. This TV was built in 2004 and purchased in 2006. How am I to justify any more purchases from Daewoo that can't be repaired after two years of use. I work for a large copier manufacturer that if you purchased a copier that had to be replaced after two years I would probably never see you as a cutomer again. I'm attaching the service tickets for credibility. I would appreciate any help with this matter. Will follow up if I hear anything about this problem.

NO PICTURE


there is a broken conductor strip or broken solder joint on the circuit board near the power input jack. do this: 1.) disconnect tv and open panel to expose circuit board. 2.) using a flashlight and magnifying glass, look carefully for this broken solder strip or solder joint. Flex board slightly if necessary to aid in finding the break. 3.) repair it using solder iron and flux solder and scratch copper conductor slightly to aid in "wetting" the solder fix.
