Good afternoon friends, I have LED that came to my hands with the problem that it was in standby and not turned on either with the control or with the manual control, I found that the plate instead of generating 12v only had 6.75v stable as I do not count with the diagram I set out to check damaged voltages and components just change a zener diode and review many welds and now instead 6.75v I have 5v also stable, in ps on I have -2.45v change filters and check the mosfet but nothing anyone Could you give a little hand? on the board is power supply; 34011174
