Question about Samsung Televison & Video
46 inch samsung tv where backlight is glowing
If the backlight is glowing then there is no problem with backlight. Check the high voltage circuit first where the 120 volts AC enters the TV. Then first the transformer, check the DC voltage on the capacitor - should be at least 390 volts. If not, replace it. The one is 100 uf rated450 volts. When I check my high voltage it was only 380 volts. So, I used two capacitors in parallel 150 uf and 220 uf (both rated at 400 volts, and that fixed the problem.

Some TV's don't have a VGA input. S-Video cable is more common. Look on the back of your computer an see if you have an S-Video jack. If you have a TV compatible output on your computer, such as an S-video jack, just take an S-video cable and connect it to your computer and your TV. If you do not, then attach your VGA end of your adapter to your computer and use the RCA, S-video or Component Video cable to attach to your TV. After you've made all the connections, make sure you are on the correct TV video input. Press the input button on your TV or remote until you see your computer's signal.

If you are seeing light then the back light is working. Can you get a menu?Do any of the other video inputs work? If no video but has backlight and no men or any on screen display replace main board.

I just fixed this very same problem. It is the capacitors are the problem. However, I think that if you have some minimal skills with soldering, you can fix this yourself. You just need to take out the system board, then the power supply parts are on the top right. The bad capacitor(s) will be bulging at the top and possibly have some brown stuff coming out. The ones that go bad are 1000microfarad, 10V, however you can replace them with higher voltage. I got 35V caps from radio shack for 1.59 each. You just need to solder out the bad ones and then put the new ones in and solder. Remember that the negative end goes on the side with the bold black part of the circle on the system board. Then just cut off the extra ends of the capacitors. If you are capable of doing this yourself, you will spend at most 6 dollars instead of however much a technician costs.
