Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

SOURCE: SP-R4232 does not turn on, makes clicking noise

Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. Or, something simple like a blown fuse inside the TV. The most common board to go bad is the Backlight Inverter Board. It what supplies power to the screen. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:

1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.

SOURCE: Samsung ln-t4671f clicking - and won't power up

This is common problem of the 46" LCD. The power supply board has caps defective. You can open the case, look for the power supply. Normally, you will see the two small caps pop up. Replaced those caps, the TV may work again. If it does not work, those FET transistor in the board have been damage. You have to replace the whole board. The board cost $150 or so. You can order direc from SS. Go www.samsung.com//us then look for Support icon. Good luck
PS: Circuitcity still sell stuff by website, you can go there and found complain.

SOURCE: samsung lnt4042hx/xaa 40in lcd tv wont turn on

I concur with Lightnbaby.... had same problem... my TV LNT4042HX/XAA took 10 min to start sometimes... the capacitors on the power supply board had bubbles on top 4 of them all 10/1000Uf. Samsung wanted to charge $220+ to have a guy come out and fix. J&J parts (samsung vendor) wanted $108 for a new board. I replaced the 4 capacitors for $4.68 and the TV works fine now!!!!!

My samsung flat screen makes loud noise and wont turn on


sounds like a power supply board problem. Be careful. I would up plug it from the wall socket.. the sound u hear MIGHT be something on the circuit board heating up and about to POP. The power supply boards are not hard to replace. just make sure it is unplugged and be careful they can carry a charge even unplugged. Caps etc can Zap u.. as I tell every one , take picture of the insides of TV and the power supply board and a close up of all the numbers that is on the power supply. order the exact same part.. do not remove the bad board till u have the new one ready to go in.. good idea is use a grounding strap. the only cost a couple dollars or so.

Samsung Tantus Model 553W HDTV1080i, when you turn the tv it just has a black screen and makes a clicking noise like it is turning on and off


Samsung has had a issue with several models, with power supply going out. The clicking noise is what lets you know it is the power supply, it is teying to cut on but has not power from the board so it cuts off. I would call Samsung and see if your model happens to be listed as the models they are covering the power supply for, your exact model number is HCM553WX. If that model is not on the list of covered models, you can ask Samsung what to do, because parts for your tv are no longer available. Hope this helps. You can reach Samsung at 1-800-726-7864

Clicking noises before TV turns on.


The clicking noise is coming from the power supply relay. Is makes this sound when the TV is usually turned on or off but has become faulty. It will only get worse over time usually until the TV will no longer turn on anymore. You need to replace the power supply in order to fix the TV.

the clicking sound is the result of a faulty power supply, some capacitors(blown heads) on the power supply for the output voltage rail of the mains board need to be replaced.

I suggest you enter the Philips model number to search for solutions already posted; unfortunately, Philips comes up too often; they were once a great manufacturer.
