I've got a Chinese OEM 50" PDP with Samsung panel and components. The TV brand is Vivo (purchased from the former Australian electronics retailer Dick Smith Electronics)

It failed to turn on a month back and I found a shorted power FET on the DC15V power supply line, ordered and replaced it. I highlighted the FET in the photo.

Now the PSU starts (PS_ON signal goes active low and stays low), the switched secondary voltages come up, look like they hit protection and then the voltages slowly drop as the secondary filter caps discharge. The PDP momentarily flashes...
