Sony KD-70X8500B 9 red blinks Another answer led me to believe it might be a tuner board? Tv won't turn on to check...

I have the same problem on a KD-70X8500B This model has a seprate tuner board. I removed the tuner board and powered on still get same problem. Can sony run without the tuner board if there seprate from the logic board? I wish there was a list of things to check if you get the 9 blinks? It says what the possible issues could be, power board? Anyone know the answers above ?
