Bought HDMI 1.4 - still Black Screen with HDMI3/DVI input. No change in the problem.
I have HL67A750 + Laptop PC + Panasonic DMP-BDT350 3D-BD + Cable HD-STB + DVD
Problem: Black screen via HDMI3/DVI & HDMI1.4 cable
, when source is PC or 3D-BD; however, HDMI's 1&2 are good, with PC & 3D-BD. HDMI3 presents HD-STB & DVD video great. I have tested the HDMI cable, it is OK. I have tried 1080p and other outputs from PC & 3D-BD with & without 3D.
I have run out of troubleshooting ideas! Why do HDMI 1&2 have good video pass through but black from HDMI3? Here is a strange wrinkle - using HDMI3 input with 3D-BD + after disconnection/reconnection of power cord, I get an instant flash/splash of the BluRay video icon!
I have the full 3D kit; however, I cannot use it without HDMI3 input! I have gray 3D choice when driving from 3D-BR with 3D demo disk playing [with black screen - see above]
Is the TV's HDMI3 broken? Is there a setup setting that could be wrong?
