I know this is an old thread, but I thought I'd add a little.
Short version: I had the long-standing HDMI compatibility issue between my Toshiba 62HM84 DLP TV and my Onkyo TX-SR705 receiver. I bought the updated HDMI module, installed it last weekend, and I can now run all video through my Onkyo receiver and one HDMI out to my TV.
Long version: I think I purchased the Toshiba 62HM84 DLP TV back in Nov 2004 and it's worked great (still does). Sometime in 2008, I ran into the HDMI compatibility issue when I purchased an Onkyo TX-SR705 receiver and tried to run all video into the Onkyo receiver and HDMI out to the TV. Never could get that configuration to work. The closest I could get was video with no audio, but that was it. After a lot of searching, I found this AVS thread:http://www.avsforum.com/avs-vb/showt...38276&page=256
and on page 256 I found a mention about the Onkyo/Toshiba HDMI compatibility issue and a link to this thread. I did a lot more research to find the HDMI module and finally tracked down the module at Sears Parts Direct. However, since I had already got everything working through some creative wiring with the bluray HDMI direct to TV, and the DirecTV receiver, Xbox 360, and old Xbox all component to the Onkyo receiver, then one component out to TV (plus all the optical and digital coax cables for audio; lots of extra cables), I thought it would be best just to wait until the TV was a little older before I broke it
I finally got around to buying the updated HDMI module from Sears Parts Direct in Feb 2010 (part number 23148055), but held off from attempting the upgrade until last weekend (23 Oct 2010). I figured since I was getting the new Xbox 360 250Gb with Kinect in a couple of weeks, this might be a good time to test my skills.
Skipping all the little details, I wasn't even sure how to get the old module out when I started, but there were a lot more screws to remove than I would have thought. Since I had never taken a TV apart before, I can say the "procedure" was interesting. After awhile, I figured out the input section of the TV was on a tray that could be slid out if I removed some more screws. Once I figured that out, things got a little easier. After moving a few wires and untying some others, I was able to get the old HDMI module out far enough to remove the four sets of cables (and that wasn't easy either; three of the four wires sets were "seated" down inside their sockets making it impossible to remove even with needle-nose pliers. I ended up having to slowing pry them out with a small flat-head screwdriver).
When I finally got the old module out, I compared it to the new one. From the outside, they were exactly the same except for the sticker on the side. The white rectangular sticker on the old module had "MHDM01" while the new module had a green rectangular sticker that had "MHDM01A", which I was guessing/hoping meant a later revision of the module which might solve my issue.
Once I put everything back together, I rewired my setup to run all video directly to the Onkyo receiver and only HDMI out to the TV. I took a large handful of wires that I hopefully no longer needed, set them aside, and fired everything up. I first went into the Onkyo receiver setup and set "HDMI Out > HDMI Monitor" to "Yes" and changed the HDMI inputs to what I had wired, set "HDMI Audio" to "Yes", and hoped for the best. To my great surprise, I had video and audio for the first time through HDMI out from the Onkyo to the TV.
So hopefully, next week when I get the new Xbox 360, I'll plug it into my last remaining HDMI-IN on the Onkyo and everything will work fine (the DirecTV receiver and bluray player take up the first two). I'll post back to let everyone know how it goes (well, if anyone is even reading this thread at this point).
Just want to say, without AVS Forum and all the people posting here, this wouldn't have been possible, so thanks.
