First step would be to call Hitachi Customer Relations @ 800-654-7013.
Ask to speak to someone in Engineering regarding their recent solution to the F59's HDMI issues (invoving the instal of a new signal block assembly). They should either transfer you or at least get some contact info for Engineering to get back to you.
Should not be an issue if your set is out of warranty (most of ours are now), as it seems Hitachi will be picking up the tab on these (as they should).
Generally, Hit will farm the job out to your local Hit tech as warranty work. May send the new part to tech or directly to you. Mine was FedEx'ed overnight to me, mainly 'cause they really
wanted to test the fix out in the wild. Mine & pinkfloyd1973's are the only 2 sets here that have had the mod done, I believe. And perhaps among the potentially small handful nationally - maybe we are it so far??(edit: To vstream....I know your local Hit tech is not "up to snuff" in your opinion. I hear ya. But, you are in the SF Bay Area, if I recall.....see if Hit will allow Mr Bob to do yours. They have authorized warranty level work for Bob/Image Perfection in the past. He's local, so I don't see why not. And hey...maybe you might spring for a little calibration work at the same time
And to Bob, I assume as always that it's OK to pimp you out here for such things! ).
For those not familiar, the part getting swapped out is the large board that houses all your inputs/outputs. The DCU is a small chrome "box" attached to the main board, with ventilated sides (looks like a cheese grater), containing the various memory circuits inside. Attached to main board via 4 solder joints - swapping DCUs is far less time consuming than a full DCAM re-do from uncorrected state (original Hitachi gameplan, part came with all service menu sections dealing with conv redo w/ screen jig). The actual mod that Hit performed was not part of the DCU, but in fact another part/chip nearby that in some way governs HDMI output. As often guessed around here, the shifting was a "handshake" issue.
Should you get a repair set up, make sure beforehand that all your user & SM "tweaks" are written down. They will revert back to OOB levels after the board swap, but changing back to written altered values takes little time. As long as the tech takes your existing set's DCU off of it's signal block and installs it on the new block, all your conv/geo/oscan settings will remain intact (but will need some DCAM level touchup work).
The old HDMI fix/software mod I posted WAY back in the Tweaks thread (and shift thread, too)has it's data remain, although your set's software will change to V020---white text, not magenta anymore.
The engineer I dealt with directly was named Oscar. Have his phone/ext#, but not with me @ the moment (plus, I'm not sure he wants to get flooded with calls all by himself!)
