Rhodes 660 Dead Keys and Dead (Dying) Pixels on the LCD
Hello fellow Redditors,
See relevant photos here. I have recently acquired a (Roland) Rhodes 660 off Facebook marketplace without a power adapter. Upon cleaning it up--due to a previous keyboard case or yore exploding--I made sure that there was no missing spings to prevent a catastrophic short when powering on.
Upon power on, I noticed a some things; (1) The LCD has some pixels that are more than others and; (2) None of my keys make any sound when pressed, with the exception of C2, E2, C3, and E3. They only produce a sound when pressed together, like C2 and E2.
Other things I noticed was that the red glue is oozing out of a few keys from the weights. I have yet to disassemble the key mechanism to check under the black keys for additional glue. As of late, it is not enough glue to be a concern until I disassemble further. Also, my aftertouch ribbon cable seems to have some damage.
Another thing to note is that I am powering this Rhodes 660 with a 9V AC adapter that came with my Roland TD-15 drum module, but should be an adequate spec for this keyboard.
Anyway, what I want to know is that if anyone has experienced working with keyboards from this era, specifically my Rhodes and its sibling--the Roland U-20--please tell me how to get it working. What should I check? Also, advice on getting this keys off would be awesome. Thanks!
