Re: Pioneer PDP-LX508D Won't turn on, 3 flashes from PSU

Hi,
I know is a old thread.But i have got similar issue.
The problem with the TV began after turning off the main fuse in the house.The TV switched on, but the image started to flash and turned off after 1 minute.
After turning on the TV, the blue LED lights up, but then turns off and flashes red.
TV on the front panel Flashing 2 times on red and on the PSU 3 times.
I bought new PSU but nothing change(may by is broken as well).
Any tips on how to check the power supply?
