Tv makes clicking noise but won't turn on

The clicking suggests a power supply issue, a old trick I use in cases like this is a hairdryer, Try to heat (don't melt things) different boards carefully until you get a dramatic reaction, considering the brand which I do not like much less endorse, what is there to lose.

If you pinpoint the issue to one board try to locate that board.

bad capacitor

The tv power supply board it got short and already dead some how,tv have clicking noises mean ur tv power supply board are not stable and not regulating high voltages to the rest of the tv other boards.The tv power supply board that the board where the a/c power cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish tv power supply board for the replacement.

The power supply board has failed, VERY common problem. You can call 1-800-samsung for the nearest service center.

Have the Power supply repaired ASAP!

Return the production without any further delay.

The problem is in power supply (SMPS)

It is very possible that the power supply may have gone out. Which unfortunately is common on many newer tv's and other appliances. You can use a multi-tester or voltage tester to see if there is any power coming out of the power supply.

I had the same problem. I work for a mother board manufacturer w/offices in New Jersey and brought mine into our engineering lab after Samsung told me tough luck. Anyway, one of my engineers fixed it in 10 minutes. Essentially, he replaced the 1000uF capacitors on the power supply board with 2 cent capacitors instead of the 1 cent capacitors that had blown out on the CHEAP SAMSUNG POWER SUPPLY BOARD. You can tell the caps are blown via visual inspection. The top of the cap should be perfectly flat and a blown cap will be convex on top. Unfortunately, there are also 2500 uF caps by the same cheap manufacturer on the board as well and we don't stock that value for our products. According to my engineer, those will most likely blow next since he replaced the others with better caps, but I'm getting samples of those and will replace them shortly. After that this piece of junk should last me at least another 2 yrs! It's been working for about 3 weeks now w/no problems. Hope this helps.

I had the same problem when I accidently hit the remote. If you are hooked up to cable make sure INPUT is on the correct setting -- AV, S-Video, YPbPr1, YPbPr2, VGA, HDMI1, HDMI2, ATV & DTV (see button on TV or remote). Hope this solves your problem.
