perhaps it'll help.
But I'd first try to see what happens via MIDI. Try to control from another keyboard, and also check if those two keys are sending MIDI commands.

Also, once you've made a (or rather two) full backup(s) of your programs and settings you can try the diagnostic mode to see what happens when operating those keys. Remember, however, that diagnostic mode will delete everything, all settings and programs on the Trinity, so it is a must to create a proper backup before going that way.

i bought a trinity with only 5 notes working. there were 5 traces with a fine scratch going through them. once i fixed the traces they all work. contact cleaner isnt a good idea imho. the cleaner wont actuall reach the contacts because they are inside a rubber housing that are somewhat sealed. so you'll just be making a mess.

opem the bottom and check the long curcuit that runs along the keybed and look for a scratch. it could be something else also but if its a scratch on a trace, you can get someone to connect them again. its real hard to do tho. but you should get a tv guy or similar to do it for a reasonable price.
