Re: LG 47LE5300 Turns on but no picture, no sound
I checked the voltages.
The only voltage that I have is 3.3 V Standby. I do not have other voltages like 12 and 20 VDC.
Seems no command is coming from processor to start the system.
Any suggestions?

Thanks a lot for reply.
Here are the pictures of TV and black connector pin voltages.
When you say: "PS-ON, BL-ON" what does it mean?
PS-ON=Power Supply On?
BL-ON=?...Leave a comment:

LG 47LE5300 Turns on but no picture, no sound
Hi,
My LG 47LE5300 Turns on but no picture, no sound.
I am looking for PSU (YP47LPBD) schematic diagram as I think high voltage Mosfets are not working.
They are ice cold which tells me they are not working. Maybe the problem is the High-voltage resonant controller is not functioning.
Thanks in advance... -
Re: LG 42LE5400 Backlighting & power supply
Does anybody have diagram of YP47LPBD LCD TV Power Supply.
My 47" LED TV powers up with no picture or sound and I need to diagnose the PS.
Thanks in advanceLeave a comment:
