So here's how today played out. My current contact at Sony is being very helpful. He actually called me first today to begin today's tasks. We tried Sony semiconductor division but couldn't get anyone that knew anything. I actually found a Sony Semiconductor Quality and Reliability handbook that I will post at a later date. Kinda funny but a useful tool for the current problem.

So here's where its at. My contact wants me to draft an email of the current problem, the part that is needed and frustration of lack of support. I will email it to him and he will be forwarding it to someone in Japan. Apparently the person in Japan is someone important because he was going to give me the direct email but then his boss told him no way. I will draft the email over the weekend and edit it as I think of more to say. I will post the final draft but not until we have a response from Japan.

However, if this process still doesn't yield results, I'm trying to get names and emails or numbers of the higher up's so we can all group together and cause mass hysteria. I will also be referencing the frustration of many other current and future Sony customers and of the conversations on various forums concerning this unavailable ic. Also that this 1 part, currently causing over a half million dollars worth of equipment to be completely inoperable and the many people hearing of this issue, may cause Sony millions of dollars in loss of revenue by those not wanting to purchase Sony devices for lack of parts availability.

If need be, I may direct them at Sony to this thread, so voice your opinion if you wish.

I will give this task my all but this will be my last attempt to solve this problem. So its do or die........

i was wondering why there were two sta lines, its clear from the block diagram, thanks john

I just got the answer from my Japanese friend :

Hi John,

I spoke to xxxxx-san in this morning.
The situation of G90 problem is very bad.
Sony announced discontinuity of G90 in 1999 so SONY does not have any obligation to keep any maintenance parts after 2006. Also Sony will abandon all parts of G90 by the end of March 2009.

What I can do for you is to ask xxxxx-san to get data sheet of IC421.

sorry for bad news.

Crying or Very sad

This leave us with the datasheet of the CXD305-127R, maybe Rolling Eyes

I'll let you know.

John

if it is a pld with a custom mask the program data would be very helpful, maybe a binary file or equivalent

So unlike the AmPro 3600/4600, Barco 1208/1209, Electrohome 8500/9500, the parts in the G70 and G90 are not the same? This part is NOT to be found anywhere but a G90? Too bad cause there seems to be plenty of G70's to scab parts from. Oh well, I still like my 4600HD and damn glad I stuck with it. Thumbs Up

When someone eventually gets the doc for this chip, just use it to build a daughter board to do what the chip did. Surely there is someone here smart enough to do that.

well, there is one last option, we'll have to build one! Hmm.. where did i put that erector set anyway ??

If a class action lawsuit worked for all those people with Sony digital cameras that the CCD failed in, would not the same action apply here?

Seemed like that lawsuit had global repercussions for Sony, they even had to fix my camera in little old New Zealand after that.

From the posts it sounds like there are a few experts on the workings of these machines that may be able to answer a couple of technical questions. I am putting a concept together to allow the duplication of the controller chip and require some basic information regarding the working parameters of the system. I don’t have a set of schematics for the machine to reference but only the snippets in the post.

First, what is the speed of the CPU clock?

Second, are the values of the analog output signals static? I.E. Values set during calibration procedures. Another way of putting it; if the projector is in an operating state, probing each analog output on the DAC’s, would you see a DC voltage or a waveform. Is it the same for all DAC’s or are there two groups, one static and one dynamic?

Any luck getting the technical data sheet/specs for the IC431 chip? With the expertise on this site it sounds like we could either find a suitable off the shelf alternative, build a chip to order (easier if the original manufacturer could be located) or design a motherboard to duplicate its functions.

That's pretty sad such a new PJ has Part problems. I could of picked up a G70 locally in my area cheap, does that use the same dreaded chip?

My antiquanted beast in my avatar I have spare parts machines for since obsolete.

I had regrets on not getting High Performance G70 Sony until now.

Sony in their infinite wisdom can't churn out a cuple hundred extra chips for the useful life of these PJs? They would only make money selling these?

Thumbs Down

I have 10 of those chips, you can have them free if you want....
