Lg Lst 4100P Power Problem
Posted 08 March 2012 - 11:08 AM
I am trying to fix a 4100 for a friend. I am a tech, but have no experience with this unit. It has no power, rectified high voltage (344V) from mains is fine, but I don't seem to be getting the power on signal from the on/off button to the base of TR2 in the p/s.
Does anyone have any experience with this unit? I have the p/s circuit diagram, but no other circuit details.

Is the power supply generating standby voltages?

I might just go the re-cap route to see.
