This may not really be a solution to your problem, but here it goes. If you are not sitting a particular distance from your tv you will experience slight pixelation. I have this tv myself and I think it looks great. Now when I am sitting up close on a station that is broadcasting in 720p(which is pretty much every HD station) It looks only pretty good...I sit back and it is fantastic. The good rule of thumb is take the number or inches your TV is in yours and my case 40, divide by 10 and then multiply by 2...and that is the number of feet you should be for optimal viewing distance. So 8 feet, you would be surprised to see how sitting this magic number away makes a difference.

SOURCE: Inverter

Verify that the INVERTER is working correctly and outputing the correct voltages.
If that is the case you should look at the CCFT (Cold Cathode Fluorescent Lamp) what are pencil thin fluorescent lights around the LCD panel. They claim these will last 50 - 60 K hours but they are still lights.

Check the fuses on the T-CON board and also verify that it does have 12vdc feeding it. If you look at your screen in darkened room you will probably see slight glow on the front of the screen.

When I try to turn on my Samsung LN-T4042H LCD HDTV it is now constantly clicking in a continuous loop and will not immediately turn on. It started out small- a few clicks yesterday morning. Today it...


There is a problem with the power supply in your TV. The regulator switch is causing teh clicking sound you hear. In order to fix it, you will need to replace the power supply. This is done by taking off the back cover of the TV, locating the power supply which is usually a yellow board that will have many high voltage capicators on it and replacing it with a new one.

Clicks on and off several times before staying on


The power supply will sense if the set is 'drawing' too much current and switch itself off. This could be the case here. The power supply board may eventually go completely bad.

Samsung tv in permanent standby


This sounds like it will be a power supply problem or a control problem. Both of them will need a PCB replacement. You will need to take it to a repair shop.
