Thanks for the offer but I was concerned if it was cost effective to send it out for repair.

I got lucky and found the exact same Noritake display on ebay and picked it up for $12.99!!

All is working beatifully now.

BTW, I found the problem with the old VFD. The vacuum tip was broken. I wasn't ...

Following your request I measured the voltages of each side of the crystal.
Facing the controller board with the power connector to the bottom left and the DB9 pin to the bottom right: The left side of the crystal measures 2.342V. The right side measures 2.144V. As I measure the regulator once more ...

No lights.

I used a 5v @2A power adapter to make sure I had more than enough current available.
I was able to make a reliable connection to the white connector. No lights. I also ran the 5V source on each of the 4 corners of the display (each group of 3 pins) while keeping the ground connected to ...

Yes, I know the flux is not a problem.

I applied 12V @ 1A. Nothing. I also tried it in a test bench pc I have (with the proper wiring of course).
How much current do it need? I didn't think it required that much more. I don't recall having power issues in the past.
Any other tips? I appreciate ...

Good Idea. Here it is. Please excuse my camera's poor image quality.
Note: The Diode and the Voltage regulator are not showing burnt marks. Thats just flux that was never removed from the factory.

I believe I purchased the wide voltage. To be safe, I applied 5v with no luck. I then use a Radio Shack, variable voltage power adapter and and tried 6v, 7.5v, and 9v (300mA).

My VFD has no marking of any kind confirming the wide voltage. Is there a way I can tell? Because I am almost sure I bought ...

Nope. Nothing at all.

Note: the serial cable works find on my other lcds. But they aren't from MO.

No Welcome screen? Wait a minute. I could swear there was. Maybe the Cajun mp3 player script did it? Hmm. I'll give it a shot.

I'll let you know.

Hello all.

A few years back I picked up a VK202-25 and the matching mounting bracket with keypad for your typical car mp3 project.

After I retired the unit, I left it for later use. Now that I want to utilize it again, the unit no longer powers up. I mean that I do not see the Matrix Orbital text ...
