heres a new one on me i have in an lg427000, it wont switch off by the soft touch power.
when on and you press the power to turn off , the red led will glow on and off then the backlight flashes on and after a few more red led flashes it will come back on....
sorry im not very good at explaining thing but basicly the tv wont turn off.
any help would be apreciated

this is what i have found, after checking all voltages , they are all fine.
however if i turn the backlight down to about 85 the tv turns off.
i noticed when i unplugged the antenna or it was on av without signal it would shut down, so i turned the backlight down on each input and its working.
this isnt a fix, im thinking a faulty inverter, but then it could be the mainboard which supplies the signal to dim, or the psu ?
any ideas would be great, cheers
