Looking at Sanyo production, the only one seems to be the VP201 (pin compatible 240Mhz BW). There is probably some caps updates around.

Last, mike talk about some "noise" in LVPS, may be something around it.

Mike, am I right ?

No, that's way too simple of a fix. Don't forget that even Sony Service had a problem with this streaking. They thought it was the CRT's. And I'm sure they changed out everything that you mentioned. To include better video IC's that they also have in their parts bin. Plus I don't believe the VP201 is physically or electrically compatible to the chip that's in there.

I too would be interested in this 1292 fix. So let's not take months for this to reach fruition. OK? In other words stop taking on new projects! :) Me first please. :)

Yes, I've stopped taking on new projects. I had to, I have too many things on my plate. I'm now funtioning on a priority basic. And for now. it's the MP-5. And once I'm able to get that project completed, then we'll move on to the 1292.

However, by no means will it be months. More like a week or so...

Awesome! :)
post #65 of 470
Any news Mike ? :)
I was supposed to bring parts of my 1292 to laric so that he can fix it, but I can only do it in 3 weeks, so I was hoping to get the mod by then... would this be possible ? ;)
post #66 of 470
Mike is busy with the mp-5 right which i would assume is his #1 priority, we will get our streaking fix

Time for a bump...

Mike:

How's the 1292 project coming?

Other than a frame for my Torus, it's the last thing I need to get done for my HT..

Really would be great to be able to say "I'm Done" assuming that is even possible..

:D

Mike,

Will we be able to do the mods with the projectors mounted?

I know you are busy with the MP-5s, hope its all working out.

Give me time to catch up on some things, and we'll get right back on track with this.

Well, if you are asking us for time to catch up on other things, I think the answer will be a resounding no! ;)

OK Mike. How's about giving us a date for the presentation of the 1292 fix? There are so many people waiting for this fix its got to the point of being a cruel torture.
post #75 of 470
Slow torture for sure .

post #76 of 470
No, slow & cruel torture... :D

Here is a point no one can argue with !!! :D
post #79 of 470
I'm still on board guys... I just need a little more time to finish up on a couple of other projects first.. ;)
post #80 of 470
Do you find him sadistic ? ;)
post #81 of 470
Mike, maybe you could already give us a few hints about what you changed on the 1292 ?
post #82 of 470
Luckily I am on vacation for the summer on the west coast while the projector hangs quietly in its room on east coast.... but still some details would be nice.

Mike Parker posted the following comment in the MP-5 thread:

David,
I plan to get back on the 1292 very soon, but I have so many other things to do first. I'm needing to mod the DX because it'll be used with 3 of the MP-5's that I'm sending out. I want to look at the final stage, to see if there would be a problem with its component out connected to the MP-5.

The 1292 is only one of the things that I have not be able to get back to. MY health is back, and my legal situation is finally in the stage of wrap up. So with all my major headaches behind me, I'm gearing to move forward. I know there's a lot of people waiting on my return to the 1292, but it's not been the only thing that I've had on hold.

Call me heretic, but is MP being compensated for his time and expertise? I can understand sharing in a passion, even releasing to the public domain in a community like this, but the expertise shared by MP (and tse, and others) just blows my mind.
Through legal and health battles (alluded to in greater detail elsewhere) all I see is a never ending chorus of "MP, when will you finish my pet project????"


Shame! For shame! You should all be ashamed of yourselves as I would be if I owned a projector cool enough to garner MPs attention, when mine would be a voice in the chorus and I'd be singing loudly "Mike, when are you going to do _my_ stuff!?!?!?" :D


Joking aside, I sincerely hope MP, tse, Curt Palme, et al are provided good livings given their contributions to this community.

yep.. I still have Mike's 1292 neck boards in my posession...it would be a shame to send them out without this fix.
post #86 of 470
I'm anxiously waiting for this mod, and I'm definitely willing to ship and pay appropriately to get my pj upgraded, as I'm sure many of the 1292 owners are... if they are gonna diy it, they should still be willing to pony up some bucks for the service...
post #87 of 470
This mod sounds like its going to be great. I adjusted the astig and flare on my 1292q for the first time. You could really see the streaking on the sides of the dots. I bet it adds a lot of clarity to the image once the streaking is eliminated.
post #88 of 470
Should do the same for a Barco 808 :) (keeping the dream alive)

Actually, I don't think it is on the neck boards..and as i begin to go through the whole logic of figuring it out... I realize it is already covered ground...and that I agreed to leave it alone if Mike was going to pursue it as a 'fix' involving recompensense. So I left the speculation 'off' the forum.

The fact that the Sony engineers seem to not have been able to figure this out..jsut boggles my mind. Or, conversely.. it could be 'planned obselesence', that was a happenstance kind of thing. The problem appears. and is conveniently left without an answer. A legitimate problem rearing it's head, that somehow, does not get fixed. Like Corvairs, for example :D Ok. Bad comparison.

I mean, hell, given some grunt work and time, I think I could have managed to figure it out. And I'm pretty damned far from being an engineer.

Ken,

I know you just got my shipping address, but don't send those boards back just yet. Mike should be back at the 1292 within the next week or so and I'm 100% sure that he'll share a little info with you so you can apply it to my PJ. He knows that this project is definitely one that you want cleared from your plate so you can move on to newer challenging obstacles rather than having to rehatch what you've already accomplished years ago.

So, hang tight! It won't be much longer and you'll finally be able to wash your hands of my pestering a$$!!!

Thanks!

Mike Hines
