Hold your horses.
Have you informed CPR ?
Depending on the game, and where they are situated, you can always change the color (if that's the issue) by installing an LED that is the same colour as the insert would be. Going to the effort of knocking out the old insert, risking significant damage, just to change the color sounds drastic to me. It CAN be done, and if done carefully, it might work out ok. You would more than likely have to reclear the playfield.
Which playfield are we talking about ?
All is good Mate ....
I purchased a playfield 3rd hand knowing the issue
in the title maybe i should of said from a new old stock ?
my apologizes
I was thinking of cutting the top to minimize the breakage ...
and cut from the underside as well and then using the wifes hairdrier...
roll over insert in the wrong place
