How to repair my Samsung TV? When the TV is turned on it powers on and off non stop until unplugged.

Model: ln52a650a1fxza (6 years old) * 3 years ago tv turned off and on. Samsung sent repair man to replaced capacitors. TV worked fine for 1 year * When we watched high definition movies or channels the TV would make a loud sign and turn off. We watched non HD channels for 6 months. * 3 months ago TV made load noise and shut down. Starting turning off and on by itself. Bought new power board. TV worked for 1 month but still could not play HD channels. Capacitors look good. * Yesterday I asked my wife if the TV was working fine. That day made a loud noise and turned off (sounded like a siren). When you now turn it on TV cycles on and off. Must unplug. * Capacitors look good (not blown). Do I replace the mother board, TConn Board, Whats the easy way to diagnose.

Hi, the motherboard could have been affected. Since you have ever replaced the power supply, its better you get a new motherboard.

This sounds similar to a known problem with bad capacitors in some Samsung TVs. Even though the TV is out of warranty, Samsung extend the repair period for affected TVs. Get your TV model and serial number off the back and then call Samsung at: 1-800-Samsung (1-800-726-7864).

Explain the problem and let them know that you have heard about similar problems and heard they were being repaired out of warranty. In my case, they sent a tech out and did the repair for free.

If for some reason they will not do it, the repair is quite simple for someone who can solder and you can find details here: http://www.thebuzzmedia.com/samsung-tv-capacitor-clicking-issue-and-free-repair/

Samsung TV...Turn on tv, it operates for maybe a minute, then shuts itself off and has a consistant clicking pattern, like a relay switch. Sometimes turns itself back on


Not knowing the specific model for your Samsung TV and how old it is, I can only offer this possibility because I've encountered what sounds like the same problem. Certain models of Samsung HDTVs around 3-4 years back have a design problem with their power supplies - they put in the wrong size capacitors (aka "Caps"). After a few years, the capacitors fail, and the power supply also fails. I think it's possible to replace individual capacitors, but most likely you will have to replace the power supply. Unfortunately if it's out of warranty, it will cost several hundred dollars, especially for a home / onsite visit. There is a visible symptom - from 2-6 capacitors on the power supply board will bulge out, as shown in this pic:digizen.jpg
You might try calling Samsung customer service and tell them you are aware of problems with their power supply design, and try to get them to repair the TV for free, especially if you are just out of warranty.

Call Samung customer service, they are doing this repair for free. I had the same problem at 11 months, they replaced the power supply board under warranty. At 2 years I had the exact same problem again and this time they replaced 2 - 50 cent capacitors on the power supply board. It took the repair man less than an hour and he had the replacement capacitors on hand. The original board and the replacement board they gave me had capacitors that were faulty. Hopefully these new capacitors will last. I have to say that I was thinking (no more samsung products for me) but I got excellent customer service and they admit that they had a faulty product and they accepted responsibility.

It won't turn on


I replaced 3 capacitors and fixed this problem. They were 1-10v 1000uF and 2- 10v 3300uF electrolitic board mount capacitors. Easy to spot on the power board, the tops were bulged up. $5.54 later it works perfectly now.

3 year old Samsung 40 inch LCD TV will not turn on


The problem is 4 capacitors on the power supply board. Just had mine done under warranty. They (Sears) replaced the whole power board but you can get larger capacitors and just replace those for alot cheaper if not under warranty.

not really advisable, it is more likely a failing fan bearing. This is an area of High tension and not for amateur DIY's to play around. Capacitors hold 22,000 volts, touch 1 and you are toast ( set does not even have to be on) Have a repair man call rather than the coroner
