it was pretty easy to do--- the hardest part was cleaning off the old goo---i used a sharp putty knife and laquer thinner. the instructions were real good.
I had to replace 3 of the ribbon wire connectors because previous attempts at repair screwed them up or broke them so with that extra soldering it took me about 2 hours--- [i suppose i could have been faster. ]
then i did the 4x memory expansion while i was at it---- (i had the memory chips waiting for this moment.
One of the issues I have remaining is the integrity of the ribbon wire connectors on mine is questionable. With such a nice panel now I want to get everything sort of perfect really. Any good suggestions for locating replacement connectors that are a match for the 4 in the Chroma Polaris?
Now I wonder if I should be looking at memory chip or other changes while I'm having at it.
My last remaining issues are that while I had gotten a replacement LED for one that wasn't lighting up, it turns out that the LED was fine and the problem lies elsewhere in the Chroma Polaris. Really a shame since before I had left to do some touring this was working 100%. Just sitting there over time some things have failed. Boo.
So the LED in the Sweep area doesn't light, but the controls seem to work. The membrane switch functions and the slider seems to work.
One other snag, the assignable control isn't working. All of the switches and LEDs work, but the slider no longer has any affect.
So, more repair in my future. First, getting new ribbon wire connectors and then tackling things one issue at a time. (I'd like to see what I can do without sending this to a repair shop.
