dim the lights in the room, turn on the set and shine a bright flashlight on the screen. Do you see a faint picture?

I would suspect faulty power supply capacitors, check for any with bulging tops.

Hello,

The problem is that there is a burnt or bad capacitor on the power supply board of the television, it is not longer responding, while it tries to respond is when you get the clicking sound, therefore it is not going to power on until the bad capacitor is replaced.

Run a check on the power supply board, you will definitely see the bad capacitor, have it replaced and the television will turn on after reassembling the television back together.

There are so many reasons for this fault. From main power supply regulator up to display panel should be checked. This is a very skilled work, that a user can't do it. Contact any experienced service technician.

It is a fatal case as the screen which is called a panel unit is more than the set cost new, sorry but it is the end for this set.

Hi,As you mentioned your tv have problem with the T con board. Normally in an lcd tv he t con board drives the millions pixels in the lcd panel in rows and columns. if any of the driver or a group of driver for rows and columns is fulty then the respected row or column will be missing in the picture. This problem can occur under two circumstances fist is if there is any loose contact in the connections of the board. if so remove all the connection to the t con board and then reconnect it. There are total six connections in the t con board. Of which five will got the lcd panel and one will go to the mother board.if there is any loose contact removing and refining the connections will solve the problem. If not then you have to replace the T con boar. Normally you can find the t con board in the bottom centre or top centre of the lcd Covers with metal cover or aluminium foil. I have added the picture of the t con board for your tv. I you need any more assistance feel free to contact me through fixya.Ajin

You may have the capacitor in power supply defect. IF you want to repair your self.. look on the power board for swollen capacitors. OR contact Samsung consumer relations and most likely you will get an authorization to repair set at no cost. JUST describe the problem as the set wont play until it heats up and they will contact your local service center. This problem is well known in the service industry.

Hmm, this sounds like exactly what I have, richard. I have replaced the t-conn to no success.....have you discovered anything new?

This tv has not gotton hit by any object or someone.Than it not the LCD panel screen problems.This cause it the T-CON decoding board is dead,that sit wright in the middle bottom of the LCD screen panel.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish T-CON decoders board for the replacement.

Hopefully a cable came loose and just needs to be "reseated" or connected. Try checking all cables you had to mess with when the caps were replaced, and reseat (unplug and replug) anything easily accessable. Reseating cables can fix issues a lot of times on cables that have lots of connections. Be very careful you don't break anything, some cables with clips can break if you don't unplug correctly. Ribbon type cables can get plugged in crooked or the little strips of metal can peel back when you plug them in. A trick on ribbon cables is to mark them with a marker right down the connector before you ever unplug them, that way you can see that you plugged it in all the way and are not crooked. Let me know if I can be of further assistance.

no. .. it's needs to be in a well ventilated area otherwise it will be an early grave for it
