Tv Model: XR-55X90J

I have an issue with the tv being unable to turned on and I got the 5 blinking red lights as well. Only after I removed the pins connecting the TCON board to the main board was I able to get the tv to turned on but screen is blank. When I plugged it back, the 5 blinking red lights will come back after I plugged the pin back.

Is this enough to deduce that the TCON board is faulty?
