Lucky you are! Does anyone need my dead P1 motherboard?

No, there's no backlit LCD on LK-280. Only keys Casio staff, check this link out - it says "Large, Backlit LCD"

Well, here's the end of my story. Received XW-P1 mainboard, soldered it and it works It cost me extra $140 (PCB + shipping to USA + shipping to Ukraine). Nice price for firmware upgrading.

If your keyboard is not under warranty, you can unscrew it and push one of sockets properly. I had this in THREE (!) LK-280s.

Got reply from Casio support (Russia): "we know the problem and you'll be notified when we have official Casio reply".

And what should WE do? WE - who updated the Firmware and got nice bricked device? I'm not alone here - at least 3 owners have the same issue. Silent Casio is not a good solution. They want to have great sales and market share with new P1&G1 products, that's fine, I understand theit business goals and aiming. From another side, potential buyers should know how Casio treats customers if firmware suddenly kills their toys

I've PM-ed Mike Martin is he hasn't replied yet. Maybe to busy these days. But we (all who suffered from firmware update) are waiting for Casio solution. Customer-oriented.

Don't you know, why Casio doesn't use braded insulated wires?

Maybe it worth to change "Windows Users: Check to make sure "XW-P1-Updater.exe" are present in the folder to Windows Users: Check to make sure "XW-P1-Updater.exe" and two bin-files are present in the folder.

It's just a retail price for XW-P1 MainBoard. I've bought used synth off e-bay, our Ukrainian Casio service mentioned "even with full warranty your case is out of it".

Well. here's the reply from Casio-parts: The main board is a part number 91087181259. Your cost is $117.50 plus S&H. We will need to order the part(s) from Casio. It usually takes 2 to 3 weeks for us to receive parts from Casio. I'm not in hurry to order this MainBoard, maybe Santa-serviceman can help, who knows

I was doing all steps according to this manual. And had all mentioned till step 7. PC program quit, Keyboard rebooted and... clear screen. Our Ukrainian Casio service told me nice facts: I'm not alone with XW-P1 and "bricked after updating" (they have 3 or more visitors with the same issue). And the only thing they can offer is to replace MainBoard (costs more than half of Keyboard price). Now I'm looking for a new MainBoard in USA or other Casio services

There's nothing to replace easily. Here's main board (I think) because it has chip and 3 memory chips (I think it's a static RAM chip and 2 dynamic RAM chips). All soldered and the only thing smart user can do is to replace (by soldering) the whole board. But it's the worst case. I'll call local Casio service tomorrow to investigate what they can do and what money I've lost because of nice and save flashing process

Jokeyman123, I had absolutely the same yesterday. WinXP on my Note, some kind of "mailware virus" (as it was investigated today) and now my XW is dead. Clear LCD, power on + write&edit does nothing And I don't have warranty as well. Cool things. After switching power on and in 1 minute later (see pics).
