Hi have a 42" LG TV model numbe 42LG7000
When I go to turn it on the power light flashes red but then doesn't turn on. Took the back off and got rid of all the dust in there. Looked at it from the back whilst trying to turn it on and the back lift comes on for 2 seconds then dimms. I've tried unplugging it for half hour still doesn't help. Please someone help me its driving me mad!
As this is an older thread I dont mind having a shot - it seems people more knowledgable about this are not in this week.
My guess is - and its only a guess - is that it cannot see an input. Is it connected to a computer, DVD or anything like that? Perhaps the input settings are wrong - or it might be out of tune. Do you get a display when you press the [Menu] button on the remote?
