LG42LG7000 Starting Problems please help

[chrisantony]

Hi

I am new around here with a little tv knowledge but not a guru...Please be kind and not too much technical chat please

I have an lg42lg7000 that has a fault when starting, it boots up, backlights illuminate then it runs through a cycle like one of the inverter transformers is down..backlights light up for 10 seconds go off for 2 seconds then on again, everything else is then redundant, you have to pull the power cable from the back of the set the power button on remote and front panel does not do anything.

I just have a backlight flashing lg at present

Any help with his one would be appreciated
