Re: Sony XBR75X850C won't power on, no LEDs

I think im having the same problem, i got sony xbr65x900c.
It just turned off and no pictures was showing but you can hear the sound.
Then this killer 4 red light blinking comes up, i replaced the TCON board with the exact part number from ebay unfortunately the same issue happens.

Im frustrated coz i only got my tv for a year, any suggestion is greatly appreciated.

I tried to unplug all devices connected to the tv ie; Media Box, HDMI's, Home Theater, LAN cable waited for 5 minutes before turning...
