I check i feel the problem with p board as i do not get +12v dtv and 17v supply.only stdby 5v and 3.3v available. But hear the relays click momentarily and see primary dc hot there to the main transformer but secondry voltages absent. I noticed that ssc9512 has vcc but reg pin 9 absent.so gate voltage absent to main dc-dc transformer.anyone know about this thanks for the help
Below I attach a diagram of the power supply from ? Panasonic LED_backlight wer.40 "(New Zeland ver.) On IC150: SSC9512.
A little reconfigured than in the org. PSU from link to ch.KM07, where IC is showing on the p.69 as IC7301.
Thankyou for the help i had the set repaired today there was no main supply to the A board the problem was with the P board r7305 1megohm which go to ssc9512 there are 3resistor in series Going to pin 1.(ac in detect)
