Restoration of dark Icom M127 screen

My old Icom M127 works perfectly, but the screen has reached the point where it is very difficult to see what channel you are on.

I found a business in Florida that offers a repair service, but sending to FL from Australia isn't practical.

I then found a August 2011 post on sister forum CF, noted below:

This film makes for a poor connection and causes some of the display segments to fade. It is possible to remove them and scrape the film off with a razor blade restoring the display to like new condition. This may or may not be your problem as it could also be that the lcd itself is failing. Either way, it can be fixed although I doubt that Icom services them any more. I could fix them for you but with the low cost of radio's these days it might just be time to upgrade to a modern class D DSC unit.

I'm not clear whether the segments themselves need scraping or whether its the side connectors. Has anyone done this?

The most obvious dual channel replacement is the Icom 2730A, selling for a mere $542 here. I am happy to try a razor first, if I know just what I should shave with it.....

GME (and others) sell a multi channel VHF at a way better price.

I'll need to check my spare unit, likely a GME. Backstory as to how I ended up with a spare not needed at this point....

I see they refer to dual watch or triple watch rather than dual band. It will not have all of the Icom functionality but will likely do all I need if it has DW. I may already have a solution in boat spares!
