I am going to be operating on a few YA boards over the next weeks. If anyone has any ideas on reading these chips, let me know what I need to try.
I have three YA parts boards here. One is perfect, on has a bad IC, and the other has a good IC with non related issues.
I could experiment with trying to read the bad IC and when I have something working on that I could move onto a good IC.

I'll look over the diagrams later and give you my opinion... 
What brand/model programmer do you have?
Its probably going to involve soldering a bunch of small wires to a bunch of pins on the ic. I'd be interested to see if the chip will spit out any info......

Craig,
Do you have my YA board from Terry or does he still have it? My G90 that had been displaying every symptom of having a bad YA board will be arriving at Cliff's on the 25th where I will pick it up at the meet. Funny thing, though. When Curt tried my YA board on four different occasions, it ran perfectly on all occasions. Curt then shipped it down to Terry and I believe he found the same situation that it ran without issues in his chassis. Who knows at this point. Let me know if there's anything from that unit you might need so we can get it to you then.
Doc

I have a PocketProgrammer2.
I will probably buy a few sockets for the IC so that I can solder to that rather than the chip its self. I also want to put a socket on a YA board for chip swapping while experimenting.

I don't have your board Doc.

Craig. Sockets sound like a good idea. I just took 10 minutes to look some stuff over quick and i just noticed something I didn't think of before. Without going into detail just yet.......have you ever JTAG'ed anything before?

Yes I have... on WRT (Linux) based routers.

Well after glancing over the info I have, it appears as though this chip has a JTAG feature. Its going to take me some time to work this thing out as a JTAG cable will have to be made. Also I have to determine whether a programmer or a PC will be the best option. And I'm sure we may fail on the first few attempts so the bad chip will be the victim. the fact that it has this feature though is promising in itself. The only reason I can think of for it would be to access and alter the logic programming. I have JTAG'ed many, many chips and this is the only reason to do so. Of course there could be more then one layer of data and the jtag may be able to only penetrate the first layer.
Let me ask you this Craig. Even on your end this is going to take some time and trial and error just to see if anything comes of it. I would be willing to invest some of my time if youd rather just remove and send me the bad chip. but if you want to tackle this yourself then that s fine too. Let me know.

I don't have your board Doc.

Terry may have sent your's to John. Better contact Terry directly to be sure.

I am no expert on JTAG, or programming, or IC design, or circuit design. I am good at all (but not an expert), and I am really good at figuring things out when I must... and I have lots of general knowledge. I would be happy to send you a bad IC, or I will be happy to get instructions from you on things to try.
One thing though, I do have mad soldering skills and working with lots of tiny pins doesn't bother me at all. Granted, when dealing with SM stuff bad things can always happen, but I have a very high success rate.
You know what would be really cool... if we find that we can read and program the IC's through JTAG and actually revive the "dead" IC's on bad boards

Doc,
It's here. Send me your address and I'll send it to you.
Testing I did with it indicated to problems.

Watch out Mac, Sony is reading this thread. They may come after you and force you to buy all of their proprietary formats. 
Man, after reading this thread it looks like the best course of action for G90 owners is to run the pj till it breaks. Afterwards you could transfer the tubes and lenses to a burnt tubed Marquee or Barco.

Even if someone at Sony was reading this I'm sure all they are doing is sitting back and laughing..........hehehe, look at these guys trying to figure out that chip...........if they only new that we got them from Samsung and they got thousands of them and can buy them anywhere..........and to boot, they are self programming from external RAM..........hahahahhahhahaha!!!!!!!!!!!!!!!!
Hey Wang... slide that crate of CXD305-127R's over here. I want to sit my ass on it for a while and keep reading this forum....I told you we could build those G90's to fail in under 10 years and make parts that are unavailable.......
pass me another spritzer......................@*&%@*&@$@%*#&@*&^#&@$%@

Or better yet a AmPro

Yea, see....... They made such good projectors that they expanded into the tool line. They weren't making enough money on projector parts because they weren't breaking down enough so they're making tools now.

Chip sell the AmPro and use it as a down payment on an AmPro professional !
