Question about Daewoo DTQ-27S3FC 27" TV

1 Answer

Will not turn on

TV was working fine.  I turned it off, left for half and hour, came back and turned it on.  It made a slight clicking noise inside twice and that was that.  I've unplugged it-let it sit-replugged it in, but nothing.  Is this another land-fill item or could it be fixed?

I have a RCA L32HD31YX12 TV. The TV works fine for a half hour and then the screen flickers and goes black. The sound continues. If I turn the set off for a half hour, it works again for another half

You have answered your own question, someone needs to open it and find a loose plug or broken solder connection--if it reacts to being tapped on that is the issue- a physical problem inside.

Tv started making a fizzing noise and now it is clicking as well with a slight movement of the screen during the click noises, goes up and down in volume now for a few days

is the fizzing noise when the screen is really bright? if so the scan coils on the tube have come loose and need glueing down with nail varnish i know it sounds strange but it really works

if the fizzing is coming from the tv then you have whats called dry joints

and this will need to be resoldered or the tv will shut down if you can do this yourself then the best way to find them is to remove the back and turn the tv on its side turn on the tv and turn off the light you will be able to see the dry joints sparking on the baord

hope this helps

TV won't turn on at all. It doesn't click at all to turn on and we checked the power cord, the plug, and the outlet. All seem to be fine. It worked just fine the night before and even if the tube went...


You are correct, the switch would still click even if something major had failed inside the TV. There is a small microswitch inside the TV directly behind the on/off button. The microswitch can break or get stuck and there is usually no way of fixing it without taking the back off the TV. You could try repeatedly pressing the on/off switch rapidly as this can (very) occasionally unstick it, but it's probably broken.

This isn't generally a user replaceable part as the actual switch is soldered to the PCB. I would take it to a TV repair shop, but if you are planning to remove the back of the TV, make sure it's unplugged and don't open it until the power has been off for at least half an hour as you can still get a considerable residual current shock!

Hope this helps.

TV has started to make a really loud humming noise, then sounds like a siren noise after you turn it off and now it has started to turn off by itself. Thinking maybe a fan? Worried it may cost more to have...

It could be 1 of 2 fans (fans are around $30.00 each) or more likely it is the color wheel beginning to fail. Color wheel will cost around $180.00-200.00, plus labor. I would recommend calling 1-800-samsung to find the nearest service center. Part should take an hour to an hour and a half to complete repair.

Continuous click noise like its trying to turn on but will not.

I have done some research and found a notorious cap and diode problem with this set. The two 4700uf caps (C14113 and C14115) on the DM1 power board (the board to the left of the sat. box when you look at the set from the back) are under rated and will eventually fail. When these caps fail they tend to take out diode CR14105. This may be your problem. If it is, you can replace the caps with 4700uf 25V 105c and the same as original diode.

My tv will not turn on

I took my TV apart and solved the problem on my own. For those of you that have basic electrical skills and can solder it is an easy fix that only takes about one hour. I removed the rear cover and pulled the left side board which houses the flyback transformer, easily identifiable by the big orande wire coming off of the top. If one looks carfully the soulder connection will probably be broken or loose which can be caused by movement or heat. I resoldered all of the connections for the transformer about 12 and the grounding wire to the left, a single black wire that plugs into the board. Once this was done I put ti all back together again and no problems since!

No picture, only sharp, squeaky noise

I'm having the same exact problem with mine! I'm looking for a solution also. I opened up the back of the TV and blew out the dust. Then I checked all connections. I put it back together and plugged it in. Now it doesn't make the high-pitched squeeking sound, but I still don't get a picture. My guess is the picture bulb is burnt out. I'm trying to find one online and am planning to fix it myself - wish me luck!
