I can sell single displays for the Pinitech UNO / TRADITIONAL models. Contact me via PM/email if interested.

Generally plasma displays wear out from use or over-voltage. In the box, they should last a while!

RETROFIT Kits are something I'm only doing on-demand at this point & I'm only selling those as a set (converts 5x plasma displays).

I'd highly recommend the Pinitech UNO DIY Kits in ORANGE however. It's not much more $$ per display & you gain many features over the RETROFIT kits.. adjustable brightness, light block foam, custom digits that look awesome. Incredible value for what the displays achieve.

Sorry, I won't be offering custom digits with the RETROFIT kits. They were spec'd a certain way with the design and materials & I have no plans to revisit the design or "update" them with features of the new displays I'm offering. The costs would go up and as-such the price would have go to up, putting them even closer to the full kit pricing.. when the full kits offer a number of additional benefits.

If you're trying to get out the cheapest way possible, it seems you'll have to find some used plasma displays for replacements or possibly buy a full LED display kit for one machine, and then have the extra plasmas to put in other machines. For LED sets, there are a ton of options these days, but if you're looking for something that will look "stock" when installed in a line-up, or that has the ability to work in the same game with plasmas and blend well, then the new custom digits I've done on the Pinitech UNO / TRADITIONAL displays would be the ticket. You don't have to upgrade EVERY game.. you just upgrade one or two, so you can gain the plasma displays that are freed up for your other games.

Also wanted to mention, for you or anyone else..

Through 2019 I'm offering a low-hassle way to try out a single Pinitech UNO / TRADITIONAL display in orange color (assembled only), so people can see how it blends with the original plasma displays. If you buy a single orange display and for whatever reason don't like it, you can return it, no questions asked, for a refund minus any shipping costs within 14 days of receiving the order. Plus, I invite feedback either way on the Pinside thread below.

A single display ships fairly cheap First Class Mail. Total cost (both ways) is about $8 total shipping if you do want to return it. That said, I don't really expect to have many people not be impressed by what they see in-person, which is why I'm making this offer

As you've found, the original plasma display single sided boards don't put up with a lot of heat on the pads. Seems some pads would lift no matter how careful you were, just from age. When I created the RETROFIT kits I expected half the people to adopt the "parallel resistor" method, which IMO cuts down time significantly and also limits the chance of lifting pads because you're only really fully replacing the driver transistors. Not many people adopted that method though.

You're welcome!
