I realize this is a long shot but I figured I would ask. 

The display on my VG-8 has bit the dust.  It has gotten so dry that it cracked and most of the traces are broken.  Can't read anything really.  I have done a bunch of research on how to replace the heat seal connector but am getting nowhere.   Why Optrex chose to use this type of connector on the X axis instead of a zebra connector, like on the Y axis, is beyond me.  These displays would last forever if they had done that. 

I realize I could look for a complete VG-8 to replace this one but I have done so much work to restore this one and get it updated that I would really like to get it going again.  Such a shame to render the whole thing useless just because of a 1" paper connector.

If anyone has a dead VG-8 with a good display or a spare display they would be willing to sell, please send me a message.  Thanks

Thanks for the reply, Elantric.

I've read, re-read and re-re-read that thread ad-nauseam, lots of great info.  It seems like anything short of a Delorean and a trip back to 2015-2018 leaves basically no repair/replacement options in 2023 unless I'm missing something.

Still holding out hope that I'll track one down at some point.

Thanks for the heads up. 

I'll keep an eye out.

Just to give hope : In Italy last year I was able to have the PCB of a GK2A from a Roland Foresta Shop (usually very high ranked resellers very close to Roland Europe) and 3 years before I was able to get a GK2A holder! So do not lose hope. Roland themselves have in store somewhere a lot of out of production stuff!  8)
