Aww no 
Why not contact Vishay in the UK and ask if they can quote you for fixing it???

Looks like you might need a new keyboard boss, whats with all the cApitAls?
Paul put 12v through his keyboard
Lol - no, just a spooky cut and paste 
Wow, you're not having a lot of luck are you!
No lol I'm £610 in on faulty DMDs so far. I have another coming Friday so third time lucky.
Here's a pic from when I had my first LED one working for a few hours until I blew it up
Vishay customer service, nice story 
Well, I took a punt a few weeks back and bought the 2 non-working displays from tyke. 5v Vishay LED and 12v Vishay Plasma. Tried out the 5v one and nearly burnt myself on a couple of the ICs after about 2 seconds. That one is all surface mount stuff and I can't do that. I'm guessing the display got (considerably more) than 5v at some point. The 12v was just completely dead.
I dropped an email to Vishay, asking for the detailed schematics as you can't download them from their website. Was told that they were not available to customers. So I asked if they can be repaired. They said I would need to cover shipping to the US for them to be inspected, then they would examine the displays and let me know if they were repairable and if so how much. I'd then need to cover that plus return shipping. That was rapidly getting to the point where it wasn't worth the chance or the cost, so I mentioned it seemed a shame to throw away what are potentially good displays. They passed the email on to an engineer who took pity on me and sent me the schematics of the plasma display, along with some notes and ideas of things to check (I have a meter and an o'scope). We were able to determine that the 5v display was basically fried, but that the 12v display was working from an electronics point of view and the problem was with the glass. In a further email I mentioned the serial numbers on the displays, at which point he said that the plasma display was still covered by the warranty as it was built last April. The 5v one might have been covered date-wise, but he didn't consider the kind of damage to be their responsibility.
So, to cut the rest of the story short, Vishay arranged collection of the plasma display from me here in the UK, had it shipped to the US, repaired and sent back all at their cost. Great customer service, although it took more paperwork than I ever dreamed possible.
So for £90 plus a couple of hours poking around with a scope and some emails to/from Vishay I've got a nice working 12v plasma DMD. This is going to go in my F14 project. I wanted a plasma display in there, but don't have all the right voltages for a normal one, so settled for PinLED some time ago. Now I can stick with plasma. Yay!
Thanks Tyke !

Thanks Tyke !
Great to hear a story with a good result.
Please pardon my ignorance but will this work with Popeye or Checkpoint? Thanks for your time.
It wouldn't work with Checkpoint as it's a different size. Not sure about Popeye
I see. Thank you. I should probably stick to something straightforward. Anything for an easy life! Having said that, suggestions on how to provide alternate power are welcome!
