Any electrical / LCD fix stuff type wizards out there?

So I have a piece of music equipment that has a small old LCD on it (MPC 2000xl) that has lines, dead pixels. It's a common problem with them due to the heat behind them I believe. So they don't make replacements anymore and until now the only way to replace them was to buy another from another machine that is faulty elsewhere. These were custom made for Akai so no other piece of equipment uses the same screen which is really annoying.

A retailer has recently started doing an exchange program where you send your old one and they send you a refurbed one for $250. They've said there's a way to fix them which they're obviously keeping to themselves.

Does anyone know how they're doing it? I've read some rumors about it having something to do with the foil behind it. I've looked at some vids on YouTube of people fixing old GameBoy screens by applying pressure where the cable meets the LCD. I've opened up my MPC and when I press right below the screen on the cable, it seems to show more stuff on the screen. I've tried wedging a load of electrical tape and also a ice lolly stick so where the LCD is in it's enclosure it applies pressure. It's fixed it a tiny bit but it's still not usable. I've seen some vids of people using heat guns on the area since they say the glue comes loose and you can re-melt it.

I'll happily paypal 20 quid to anyone who comes up with a solution that helps me fix the screen.
 
The LCD glass has a transparent conductive layer of ITO. This is bonded out to the circuit by a self-adhesive contact flexy. With age the bonding glue fails and you get dead lines.

My guess is that they have spares or people have re-manufactured the flexies and are cleaning up the LCD and refitting the flexy.

The question is whether you are prepared to pay whatever to get the ting fixed. You can have a play yourself, but you risk making things worse...

what he said - I used fix lots of small lcd displays on car radios. the lcd itself rarely went wrong, just the connections.
 
Like I said, I imagine it is just where the cable meets the screen. pushing on the cable at the bend makes a lot of the pixels and lines come back. This thing is tiny (200 by 30 or something). Is it worth trying to remove the cable from the LCD and then re-glue it with whatever they use in the first place?

I don't think this company are using spare parts since about 95% of the screens die in the same way. Something to do with the design where heat comes from underneath it from being on for long periods of time.
 
Do electricians fix these sorts of things or is there somewhere I could take it who might have a clue how to fix it? I imagine the ribbon cable could be replaced possibly.
