How reset tv?

Re: lg 26LC2R lcd tv backlight turns off

I think you're right.
Since yesterday was presented a problem: no sound!
Thank you if you can give me some suggestions .
I measured the values on the psu and they are ok except on P201:

Pin 2 (ON) is 2,80v
Pin 13 (3,4v On) is 2,07v

I have doubts about these
Pin 5 IC is 4,67v
Pin 10 is 3,30v... ok?


Thanks for the tips

Ok, thanks.
Is this bypass?

But, why IC OZ9936 protects inverter?
This can cause more serious damage to the inverter and the lamps?Re: lg 26LC2R lcd tv backlight turns...and the lamps?Re: lg 26LC2R lcd tv backlight turns

Re: lg 26LC2R lcd tv backlight turns off

Sorry for my bad English.
I have the same problem.
I work out like this:
I turn on tv in AV4 (or AV1, 2 or 3 it is important that nothing is connected);
If you're on TV or HDMI, change the input quickly before it turns off the backlight;
I look 1/2 minutes and step into AV1 (where I connected the decoder) and the tv works fine!
Perhaps it is a protection on the TCON or main board.

I want to ask two questions:
How many volts on the PSU: EL5 EL6 EL11 EL12 EL13 EL35 EL36 EL40?...
