Question about Samsung LN-T4042H 40 in. LCD HDTV
Where can i find replacement bulbs for lcd tv's?this is for my 40'' samsung ln-t4042h. when i plug in the tv, the tv turns on and then goes blank but if i hit menu and get a light bulb and put next to the screen, you can bearly see the image.

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.

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.
