Mike Parker 250 MHz thread.

This is very similar to the problems you were having before you got the later version Moome card.

But regardless, the section of any of those boards that has been modified or changes made to it has nothing to do with any of the sync or timing circuits. Only the video section was modified to include the supply rails to the video circuit, so in no way could any of the things you listed be related to the video section of the boards.


What happens when you bring up the internal test pattern, are you seeing everything as it should be?


Also, those boards were the same set that was in my Marquee. They were tested on a many scan rate, that is how I check the boards in the process to make you they are stable from one scan rate to the other.


This is not the right thread for those neck boards, a thread has not been created that deals with them. they would be more of in the 250mhz range (as shown in the listing). These are dialed down a bit for better noise performance (low end - black level).


************************************************************************************************

I took it upon myself to create this own topic about these special boards.


But yes, the internal test pattern is Ok. Even made some basic convergence.

Other than that, nothing is working really.

I can update as I go along.

I took some images of my current situation.

The screen shows a white field as all black.

HTPC in the works.

Do you have another source you can connect to the Moome card? A blu-ray player, maybe? Or a different HTPC?

[thewolfman]

I will try to get hold of a blu-ray player to run 60Hz to it. But I do have a second pc that I totally forgot about.. I should dig that one up and try.

Thanks for posting this.

The images from the PC clearly show distorted text on external, but not when you bring up the internal pattern. Which means there is definitely something wrong with the source.

The difference between the source and the internal patterns is a switch only. This version mini board does not use a clamping circuit )for black reference) it gets its reference from the source. So when there is no input on the source, you will see either one of the colors full on or any combination of thum bring off. This is what had mentioned in previous threads about this "one black reference" feature. So that is normal when therris no source.

Show a picture of a convergence grid with red/green then blue/green

[thewolfman]

Sure. Hold on.

[thewolfman]

Red over green convergence works. Blue over green works. I didn't make pix because they look the same when exited. So only menus works right now. Red+Green + Green+Blue.. Blue+red.

[mp20748]

Try 1920X1080P 60hz on your HTPC.

[thewolfman]

I'll try later, to bright conditions right now.

I don't know I haven't been working on it. But I'm quite positive the moome is broken. I'm going to leave it alone until the other one get's here.

[thewolfman]

I got it in the mail today, and installed the modded moome V3 and it still looks like before, with everything white being black and so forth. So I then installed a stock VIM 02 + your modded 250MHz VNB and then it works.

So, your modded VIM 02 is the culprit, and since you made a replica of this VIM, or was it just the VNBs?, anyway, I feel it's fair to send this one back and we swap. You can't fix this board because of the cover ups so you must make a new one or we swap.

I hope you will honor the warranty and fix this for me, and also make it fit the bill with the amount I paid for this, a record high I'm sure.

[racerxnet]

Mike has been very good regarding repairs on his boards. I've had mine repaired when one failed.

MAK

[thewolfman]

I know, he fixed my modded VIM 03 so I know he can fix them. It's just that the major modded bits are incased with black cover up so he would have to make them all over to repair. That has to be a lot of work to repair also.

[greg9518lc]

MP can fix the modded board so you need to send it back that's what the warranty would
cover and if it can't be repaired you would get a new one at MP disscresion. Times wasting ship
away............

[thewolfman]

I have this spare stock VIM 02 to go along if necessary, before sending them back I need to hear from MP it's OK.

Gentlemen, to back up what Mike suggests, it is ALWAYS best practice to directly contact the vendor if you have a problem with his product or service, BEFORE you go public with it on a forum.


Wolfman, you should be communicating with Mike via PM or emails, NOT turning this into a public display on the forum.

I have full confidence that Mike will address any problem that he bears any responsibility for.

Wolfman, you, on the other hand, must exercise due diligence and ensure that the problems you are seeing are truly
problems that are not due to any issues you are having which are external to the projector.

Which is easily done. Disconnect your existing external sources, use the internal test patterns to verify basic operation,
THEN look at connecting external sources.


I can not even CONCEIVE of a way that a VIM will give you reverse video or do what is pictured, not in all three channels at once.


But Mike knows more about the operating principles of the VIM and neck cards than I ever will.
