Hi have a 42" LG TV model. 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 it's dimming. I've tried unplugging it for half hour still doesn't help. Please someone help me its driving me mad!

Capacitors on the TV's motherboard are probably damaged. You'll need to check all of capacitors.

If you see a capacitor that is domed on the top instead of being flat you'll have to replace it with same voltage and same farad rating.

When you remove old capacitors, take a picture to be sure to replace it the same way! ;-)
