SOURCE: how hard it is to replace by yourself main board Samsung LN-T4065

You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.

The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.

SOURCE: Which Replacement Power Board for LNT4665F Samsung LCD TV?

It would be a lot cheaper if you just replace the two caps that have gone bad. Just get a cheap solder pencil from the store and about an inch of solder and you are in business.
The Power Supply Board is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.

Thaks for using FIXYA, BIG IRISH.

To solve this type of problem, you need a piece of white chalk. Draw a line around the area where the set is at. Call a priest - and lay the poor thing to rest!!!! This isn't the first time Samsung has "dropped" junk onto its' customers. Their dvd players also had problems with their DSP I.C.s that would over heat and cause the video playbacks to "break up". Don't waste any more time or money on the product!!!!!

To solve this problem you have to open your tv and using a hair dryer het the are of the control panel this will evaporate the moisture at the touch panle switches . After that reassemble the same and check. The problem will be cured.

Have a samsung LN52B750 that was on during a lightning hit. It gets power but it will not turn on. You can hear it clicking and the red led power light blinks 8 times. Help


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.

Thank you for using fixya

This should be repairable. It may be the LVDS Cable or the Main board problem. The only other problem is the T-Con Board.
