Question about LG RU-44SZ61D 44" TV
I've had this set for about 3 years. Once in a little, over the past year, I would hit the power button and it would take a little while, longer than usually for the screen to appear. Sometimes it would try for a while and shut off. I unplugged the tv and pushed power and it would start. The other morning I turned on the tv and it started as normal but the screen was darker, and stayed that way for a bit. I turned it off then back on again and it started and was fine. I walked away for a minute and came back to a blank screen but with sound. Then it immediately shut off. I tried for hours to start it up again, but it just keep in stand-by mode for a minute then shut down. There is only the one power supply light on, it's flashing when trying to start. The light indicator is off, but if I recall, had always been on. Also when it's trying to start up, there's a wierd screeching sound for a second and seems to occur twice while starting up.
Please help. I don't want to call a service man out and spend another $500 to repair it. I've read it could be the lamp.
Most likely you can have 1 or 2 problems.
1! the light is busted and you will have to replace that. You might also need to check your cooler fan bearing as you indicate it makes noise.
