I talked to Panasonic Concierge and they told me this is a well known issue, and has to do with the rear HDMI ports and an incompatibility issue.
Turns out i need a "GE - 22703 - ULTRA PROGRADE™ HDMI™ EXTENSION ADAPTER" in order to use the back HDMI ports.
To me this has nothing to do with incompatibility, but more so with the signal not being boosted strong enough for the Pany TV to use it.
She said different software is used on the front board.???????
Very strange, but if it fixes the problem, so be it.
Anyone know were i could get this thing in London, Ontario?
Any help would be appreciated,
*Update 1: I just thought of something important. My Bell ExpressVue 9242 PVR comes with a cable that has a DVI connector at one end, then you use the adapter to make it full HDMI. I wonder if this might be the issue and if anyone else has tried changing the cable for a true HDMI cable.
*Update 2: Im wondering now if maybe the issue is this DVI to HDMI connector from the PVR to the back HDMI 1 connection, because after reading about boosters theres a warning that they cannot use the 5V HDMI voltage if used with a DVI to HDMI connector (this is to supply the power to the booster). Im now wondering if Panasonic cheaped out based on the 5 Volts supplied by the PVR. This would make sense in my case, because i cannot see why the front HDMI works but the 2 in the rear dont, or intermitently. This would make sense based on what they are saying at Panasonic about the equalizer/buffer thing?
This info comes from the service manuals...but dont quote me on that:
10 blinks Sub 5v SOS / Main 3v SOS DG Board
DTV 9v SOS / Tuner Power SOS
After seeing this, i realized that it would not get the 5 Volts from the PVR because of the DVI passtrough issue.
For some strange reason this does not happen on the front HDMI 3 port. After some thinking, i remembered seeing this port labeled as GAME PORT. Most gaming units would not supply the 5 Volts needed, and thus they must have set it up to eat more of the 5 Volt line from the Panasonics power supply.
Basically i think they are using the 5 Volts supplied by your HDMI capable devices you hook up on the rear ports, which is why they recomend the booster.
Buffer usually implies amplifier.
My problem is not using a PC Graphics card, but rather a PVR with a HDMI to DVI to HDMI cable, effectively killing the 5 Volts supply through the HDMI cable to the rear of the TV. I think that the people using PC's can solve their problems with this "GE - 22703 - ULTRA PROGRADE™ HDMI™ EXTENSION ADAPTER"
Yes i realize this is so you can use longer HDMI cables, hence the boost in signal strentgh but it also amplifies the signal, HDMI does not like long cable lenghts like SVIDEO cables.
