picture in TR display was distorted, problem was in the cards of the psu
TR did not respong when turning on knobs, if it did respond some other parameter was also affected, problem was dust in a channel slot
automation did not work on some channels, problem was bent legs on IC´s in the computer, we went through every chip (How that happened only former owner knows
Cut lamps flickered shortly, sometimes the console switched off all cut status made on the console completely, it was better when console was warm, problem was a leg was off on a J112 in one of the cards, the one to the right from behind
Problem that is not solved yet, display in console and external display starts working after 10 min
Reel floppy is not responding sometimes when console is not heated up
