Hi,i found this thread after a google search.Looks like you have the exact same problem i had with my mtc900 chassis,a red screen with retrace lines.Anyway i was lucky cause i have two mtc900s,one wont power on.Either would this one till i noticed the lopt had about four cold solder joints,once i reflowed them i had power
Then i just compared transistor values on each board with my dmm and found TR33 on the neckboard didn't read the same between collector and emiter as on the other neckboard.So i replaced it,powered it up and got a black screen,no more red retrace line screen
Put a game into it and,it didn't work

After a lil head scratching i noticed the game had no sound,tested the voltage on the harness and i was missing the 5 volts output,the 5 volts has a dodgy wire,gave it a wiggle and on comes the game.I got very lucky with this,but theres no better feeling when ya can get these things running again
Thats my third chassis repair
Anyway i just thought i'd share this with you as its the same problem.Hope you get yours sorted
