My tv just stopped showing a picture. There is sound, but the green power light blinks. After a couple days, i turned it on and it worked again. Now it doesn't AGAIN. I checked the lamp, and it is fine. I did notice some minor "squealing" cominf from or near the lamp housing. I live in a 100 year old house with poor wiring. Could it not be drawing enough electricity?
The sqealing noise is going to be one of the cooling fans or the color wheel. The color wheel is famous for making noise. Some are louder than others. The most likely culprit is going to be your ballast. You can find them on Ebay for under 100 dollars. You can also find a spare bulb for around 85 dollars. I made it a habit to keep one on hand just in case it went out right in the middle of something.

the circut that detects the bulb has been also failing in these sets
and the conversion chip that controls the picture , and the transformers are not putting out the full power they are supposed to.
this set will need to be tested to determine the exact cause or causes
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.
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!
