Most probably power supply board is defective and causing this problem, Samsung tv has common problem with power supply board so replace this board or check its capacitors that would be leaky/ dried up.
Hope these info will help you.
Let me know if you have additional question.
Thanks.

Turn it down first... Access the menu, (could be a problem through a cable box or the television itself) and check the audio settings. Make sure you have your inputs/outputs in the correct positions!

You have capacitors in the power supply that need replaced. Not an expensive repair but you should not attempt this yourself. It can be repaired in the home.

Tries unplug,replug it back like about an hour later.The tv now,will resetting itself back to the factory setting.The tv now should work.If not the power LED light indication on the LCD screen panel flashes or take 2 or 3 mins picture to come on.The problems is the tv power supply board,that the board,where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.If tv was bought and it under a year old,call Samsung Corporation for a warrenty repair.

My 1 3/4 year old 52" LN2A750 began doing this same thing iover the past week. After isolating thew problem to the TV as opposed to the power strip, Direct TV box/remote, etc., I looked this up on the web. It became immediately clear that this is a well known capacitor issue that Samsung will fix for free. They will try to tell you that your TV is not included in this program as they did me. After indicating I was going to escalate the issue, I was able to get them to agree to fix it for free (howerver, only if it is a capacitor issue which I am prett comfortable it is). Go ahead and call them at 1-800-SAMSUNG.

Hi:
Check for faulty capacitors on the power supply on this model. They will be puffy on their tops indicating overheating or leaky. Most caps tops of the electrolytic type capacitors are flat. Look for ones near the connector coming from the PWR supply connecting to the main board.

Yes they can be replace you can open the back panel two screws and replace speakes.

This tv 100% have power supply board problems and might also have the T-CON decoders board problems too.The power supply board,that the board,where the power a/c cord plug into it.The T-CON decoders board,that the board sit wright in the middle bottom of the LCD screen panel.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.Replaced the power supply board,should get ur tv power up right away and work,no more series of clickings noises.But,if the tv still have alots colored pixels lines on the screen.The T-CON decoders board it also dead.Replaced the T-CON decoders board too.

It sounds like you did not properly reinsert the ribbon cables, also verify that you do have 12vdc feeding the T-CON board, you may have to clean the contacts on the connectors also.

there is problem with your power board fet or drive ic faulty. Check voltage some one missing. like 12v,32v,5v,24v dc. Which voltage missing only same line.

The default connection is usually HDMI 1. The possibility of the cable being defective, or the box sending a signal out need to be determined.

Set up your connections, then turn on your TV.

Try using different HDMI hookups.

Bring a different video source to get the TV to display.

See if you can bring up the TV menu to select an input to connect to.
