Question about Televison & Video

1 Answer

Samsung tv keeps switching off as soon as it's switched on what should I be looking for to fix it?

I've taken the back of the tv off and had a look at all of the capacitors and none of them are bulging or leaking, is there anything else I can take a look at myself? What should I be looking for? Don't want to pay for a technician if I can fix it myself. Any help is much appreciated.

The tricky part is that a bad capacitor doesn't always have a bulged top. sometimes they look perfectly normal. I would suspect a fault with either the power supply or main board. You don't have to pay to have a technician fix it, but pay a technician to properly diagnose the set. Once you have a proper diagnosis, you can then buy the part and install it yourself and save money.

This is just a shot in the dark but it's possible that your power supply uses a full wave rectifying bridge made up of 4 diodes to convert the AC to DC. Check these diodes out to make sure they're not shorts or opens. You can use an ohm meter. They should look like a low resistance from their anode which is the + terminal to their cathode which is the - terminal and a high resistance the other way around. If your power supply has a little starter relay in it you can also check to see if the relay coil has been blown. It should look like a low value resistor. Unsolder and replace anything that doesn't pass these tests.

In almost all cases where the set is taking a long time to turn on and then turning off it will be the Power Supply board that will have bulging capacitors, usually three to five. Look on the upper right side of the Power Supply and look for any blown caps. You can replace these caps and you will be fine. Now the other cause can be the Power Switch is shorting out. You can disconnect the the Power Switch but not the IR sensor and then turn ON the set with your TV remote and see if this stops the problem. If you are not skilled in component level repair on the Power Supply board then buy a new Power Supply board and install it.

You either have a bad Power Supply board or the front Power Switch is shorting out. Have a tech check out.

power supply board is dead, if you know basic electronics' and soldering you can handle it ? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.

Good luck in solving the problem.....

My LCD TV Series 530 keeps on blinking and would not turn on. why does it keep doing that?

I've experienced similar issues with a 42" Samsung LCD TV. From what I've read online, I believe it could be a problem in the circuitry of the power supply. Apparently, Samsung used under rated capacitors in the power supply and the result is a turn on delay or blinking on and off. If this is the case, then the capacitors would need to be replaced to fix the issue.
