Hantarex MTC900e - white screen
grantspain:
ic4 is the +12 reg
CathalDublin:
OK I re checked my voltages from the main board, see video, maybe I’m doing something really stupid but I’m getting 19.2 on the 12v and 13.9 on the -5v
Measuring from here
See video
Measuring the input on IC1(7905) reads 0 and the output reads 13.9/14
grantspain:
i read at the neck card with chassis fully connected and running
CathalDublin:
19.3 and 14 from the neck card with a game running
Can see interference on screen with game running, no colour, everything’s white
grantspain:
what is the chassis b+ reading, use one of the centre 2 pins of the deflection coil connector and frame as ground- should be around 126v
