Yeah thought the tube originally so i swapped parts between another machine.
I didn't explain very well in my previous post.
Swapped the monitor assembly to another machine and the fault followed. Then swapped the crt/neckboards between monitor assemblies and it followed the crt/neckboard.
Makvision c2929 crt board issue
I've got a Makvision c2929 monitor that seems to have no blue/red and is overdriving the Green.
I've managed to swap the crt neckboard between machines to establish the fault is somewhere on this board but am struggling to find a cause.
Tried changing the lM...
I've got a Taito Power Supply from an old Space Invaders. Ove of the L shaped boards.
The Number on the power supply is AA017741
I have a couple of resisters I need to replace but the colour markings have burnt away.
Is anyone able to help me identify them or supply a circut schematic...
