Sony KV-27S42 Black screen and blinking standby light

[grossbard]

I removed the data line from the tuner by removing the series 100 ohm resistor and the TV is still showing a black screen (with retrace lines if I turn G2 up enough) with a constantly flashing standby light.

I am getting around 5v on the jungle IC data pin, and 9v on both VCC pins. Not really sure what else to try without a scope. I've gone over the board several times tracing out circuits and looking for cracks, cold joints etc. I think i'm going to order a replacement jungle IC and try that next...
