Hey guys I have an LG 52DC2D and today it started randomly turning off right after pressing power
It is a DLP and it seems like the light is attempting to come on, and tries several times, then fails with a solid red light in the temperature LED

Does this mean I need a new lamp? I don't want to buy one and then find out that something else is wrong with my tv and I should have just bought a new one sad.gif

thanks in advance for the help

I don't know off hand but does this tv have a lamp light? Usually when the temperature lights comes on, it might be over heating. Try checking the fans to see if they are spinning. Sometimes these things can get clogged causing all sorts of problems. Also pull the lamp out and look at it to see if its going bad. See if there are any deformities on it.

Is that the full model number? Tomorrow, if I remember, I'll get my login information and login to LG's website and see if I can get the service manual for it.

LG 52DC2D-UC is the full modelname

Also, I should have mentioned but I had already checked the fans before writing this. There is one fan directly in front of the lamp and one in front of some random electronics behind another panel, and both appear to be working great.

I have not taken the lamp out, but AFAIK, DLP were supposed to get dim over time, and the TV still looked great when it would turn on.
The tv, in addition to the temperature light mentioned above in my previous post, also has a lamp led that is supposed to indicate when your lamp starts going bad. This led has never flashed since the tv has stopped working, nor has it ever lit up in the 2.5 years I have owned this TV

What happened was I was playing some PS3, and looked away from the tv for a second, and noticed the TV had turned off. I thought "thats weird, hopefully the bulb didn't blow up!". But I turned the tv back on and it worked fine.
I thought that it was strange, but kept using it for quite a while after this and there were no problems.
After turning the TV off, leaving the house for several hours to go run some errands, I came back, turned the tv back on, and continued playing Uncharted 2. After about 10 minutes, the TV turned off again. This time it would not turn back on and flashed a solid temperature light
According to the user manual, the temperature led can tell you three things:

Orange LED: TV overheating, check the ports to see if they are blocked
blinking red led: Projection tv shuts down, check your cooling fan.
Red LED: The projection tv shuts down due to overheating

I dont know if you would consider the led red or blinking red because it only flashes the light for a split second. I am inclined to believe that it is the RED LED case, since it only flashes once and the fans seem to be working.

When you turn the TV on with the bulb door open, you can see something that isn't the lamp light up and "sound" like its attempting to start something up. It tries this several times, then fails with the LED mentioned above. I can probably get some video of this if it will help.

I have the user manual in PDF if you think it can help you. I haven't been able to find the service manual sad.gif

Can't remember exactly what failed, but it was about 400 to fix at the local tv repair shop. I think it might have been the color wheel. Either way, it was definitely not the lamp.

Thanks yaazz,

I just had mine repaired and it was the lamp. Cost was around $300 for the fix. Not sure what I could have done it for on my own.
