My Sharp lc-60p6070u shuts off when on HDMI1 or HDMI3.  HDMI 2 seems to work okay for now.   I've had problems with the power supply board on this tv in the past so I replaced that without too much diag but I'm having the exact same issue after.  Are there any components that would be notoriously suspect ?  I'm fully capable of diagnosing,  but any help is warmly welcomed.  🙂 
Thanks
