Samsung LE32S71B TV Led continuously keeps blinking.

Nederlands antwoorden mag ook, maar ik wou het veralgemenen en schreef het in het engels.

Hello everyone, I recently got a TV from a friend wich he wanted to throw away because it had a malfunction.

Because I'm not really one of the "throw it away" type of men, I decided to try and give it a second life. Now I've ran into a problem, I noticed that the Red Power Light continuously keeps blinking, I've started reading about it alot and I noticed people talk about broken capacitors, I opened the backside of the TV and went to take a close look to each individual capacitors on the first sight there is nothing wrong with them I don't see any damaged capacitors nor blown up/leakening. Any suggestions what it might be?

Could still be a capacitor do you have an ESR meter or capacitance setting on a multi meter? Also when the red power led starts blinking does it follow a pattern?

Hello, I don't have those sorry. And not really a pattern, Just on off on off on off never stops its like a second on and then goes a second off again.

If you have no way of testing the caps then you're very limited in what you can achieve. You could take a shot and replace the power board and hope that works, You could invest in both of those things that I said mentioned and a soldering iron then learn how to fix things like this. Then you could do tv repair as a hobby for friends/family or to make some extra money on the side.

I’m going to see if someone around me has a multimeter I can lend for a short period, then check the capacitors, if the problem is not in the capacitors any idea what else I need to check?

による

Yes, You will need to check you are getting the right volts for standby etc

@herblore this could be a multitude of things. the constant blinking (no pattern) is indicative of an error with the power management system. The quickest way to test is by disconnecting the main board from the power supply board, plug in the power supply board, after that you should see some lights in the screw holes if the power supply is good. If you do not, then you can either move on to the mainboard. Worst case scenario would be a bad panel, which can also cause this error. Not quite sure if the images you posted were originally that small but whatever happened, I cannot make out much. Try to post some more at a higher resolution. Let us know if you have access to a multimeter so you can measure some things. Of course, a bad capacitor is always a possibility as well:-)

1. Check the various cable connections first.

- Check to see if there is a burnt or damaged cable.

- Check to see if there is a disconnected cable connection or a connection is too loose.

- Check to see if the cables are connected according to the connection diagram.

2. Check the power input to the Main Board.

3. Check the voltage in and out between the SMPS Main Board and the Main LVDS Boards.

Hello and thanks for the respond, I’ll test it tomorrow and send an update, so I just unplug all the cables going to the (green) main board? And then look if there are lights on the power board? Is that right? And I will try to see if I can lend a multimeter somewhere. Sorry for the small pictures I took them with my cellphone that might be the reason of the size. No damages or burn signs on any cable, already unplugged all the cables and put them in again so no lose cable. Option 3 I can only check with a multimeter right?

による

@herblore not lights on your power board but on the back of the panel. #3 is correct.

による

What panel? Sorry haha I’m kinda new with flatscreens.

による

The back of your screen. A lot of times you can see the backlight coming on through little holes on the back of it.

による

Okay thank you for the respond, I will try that. So I just disconnected al the cables going to the main board?
