Toshiba satellite P855 won't boot. Start button led illuminates four flashes, then shuts down.
No display, no other leds illuminated. No sound.
Power supply indicates 19.5 volts DC.

Most likely a dead motherboard, can't seem to find any modern info about the Toshiba blink codes, just something from almost 10 years ago https://www.technibble.com/forums/threads/diagnostic-blink-codes-for-toshiba-notebooks.19067/
