check if the back lamps are still on when you lose image, all you have to do is get close to the screen and make is totally black and if is not that means you have a back light working, but if the back light is gone you may have a defective panel.
talked to samsung TA about the same problem I had and the recommend to replace the power supply first to confirm a defective panel because a panel is quite expensive
Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.
The power supply is defective on your LCD and will need to b e replace or repair to the component level.
Service parts seem to be a bit hard to locate now a days.

Problem: Samsung LTM1755B with only a blinking yellow LED when you try to turn it
Solution: I just had one of these come in. I opened it up, and found
the U501 capacitor a little suspicious looking, in that it had a
deformed top. It was a 470uF 16V electrolytic 105degC 10mm x 12mm. I
replaced it with a very good quality 1000uF 16V electrolytic 105degC
10mm x 16mm Nichicon UHN1C102MPD. After that repair, when I tried to
turn it on, the LED was yellow for a second, then green, then I got a
picture, and it appeared to work great. I then asked the owner a week
later how it was working, and they said it was working just like new!
