I have the same problem and had have to many problems with this TV. I'm going to purchase another TV and this time it is not going to be a Samsung

it's the T-con board attached to the lcd panel

Check the connection of LVDS cable, (the flat cable that connects the T'Con board to display panel) for any loose connection at it both connection ends. If you wish to get some details, http://electronicshelponline.blogspot.com/ Pull up older posts.

As you will probably know , when the TV is clicking , that means that the protection circuit is on because a fault ad been detected.

If you already replaced the PSU and the control buttons, then grab a service manual and follow troubleshooting diagrams to test digital controller board (main board) and inverter board.

The manual can be ordered from Partstore or Vance Baldwin.

Possibly a bad HDMI cable connection. Remove cable, then reconnect, with the plugs firmly in the jacks. If that doesn't work, then borrow an HDMI cable from a friend and see if that fixes the problem.

You either have a main board or t-con problem. What color is the screen? blue? white?

This may be a problem with the flex tab bond. See video that explains this issue and how to fix

On the remote or on the TV? You can tell if a remote is working by pointing it towards a digital camera (like on your phone) and pressing a button. If you see the IR sender flashing then it's working.

What type of cable? Component and composite video cables can be tightened up by lightly squeezing the outer metal ring with a pliers. I've acheived the same success with an hdmi cable but it is slightly trickier. Creating a slight indentation will increase the drag when you press it in and should help hold it in place. Otherwise, add velcro somewhere on the cord and on the tv to help hold the cable in position. Good Luck,

You need a tube.

negative picture is a fault with the screen driver it may not be connecting properly and a cleaning of the board may be all it needs. failing this it may need a new or replacement screen driver. the driver is located on the back of the screen. on top of the board there are clip connectors. take board off and with a ruff cloth clean the copper end to the screen, brush off the dust of the rest of the tv and boards and in the gaps in the screen controller board. then put back together and see if it has sorted it. if not it will need replacing.

There is a bad capacitor on the circuit board which is quite common. The IC"s usually need to be replaced. The convergance is off due to these faulty capacitors.

Sounds like you blew a capacitor on your power supply board. Common problem that is addressed elsewhere on this site. I had the same problem on my Samsung LNT4672F, and replaced the blown or bulging capacitors with better ones. That was about 4 years ago. I now am having other issues with the TV, vertical multicolored bars across the screen, and am seeking resolution (pun intended).

There are 2 hinged black retainers. Gently pry them up and the ribbons slide away from the board.

More than likely it is the T-CON board that went bad in your television set. Fairly easy to replace yourself you can buy online on ebay. Search T.V. model # followed by T-CON and one should be available. There are many youtube videos on how to replace step by step. GOODLUCK!

The problem sounds related with its energy recovery circuit. Check this link for more details about these kind of fault.

Check and replace damaged component/s in the HDMI section circuit. The maim board might need replacement.

It sounds that one or two of its back-light CCFL lamp/s has burned out. Check it.
