Hi everybody,
The problem with this tv is that after 15 minutes of working the image goes off and the sound too;it seems the PS stops.So I'd like to see the Service Manual and most of all the diageram of the Power Supply.Thanks.

Hi,
Downloaded the Service Manual I found out that the Power Supply is missing.So, I'm still looking for that.Does anyone get an idea where to find it?
Thanks,Michael

sorry,
lg dont supply diagrams for psu, but i know them reasonably well, what is your problem, if no 5v line check bridge and r109.
good luck

Hi,
Thanks for the reply,but it's not the St-by supply that stops,it's the main supply to stop;when the TV stops working the green LED stays on,the inverter shuts down,and casually there's some noise from the loudspeakers;maybe the micom works erratically?
Some new ideas,thanks!
