Hi,
Does anyone have the schematics for the Tandy 1400HD internal PSU?
I only find information about the 1400LT PSU, but that one's very different.
It would be nice to know more information about the test points on the PSU.
When I got this, the 3A fuse on the PSU was burnt through, so I guess the previous owner used the wrong adapter on it.
I have already replaces some caps that leaked.
At this moment, it get only very low voltages instead of the 12v and 5v. My screen turns on but does not display anything (only blue backlight) and I can enable the caps/num/scroll lock lights by pressing the keys. When I press the F1 key, the light from the HDD starts blinking, but I hear no HDD noises. I hear no beeps, the floppy drive does nothing.
Any help is welcome. Thanks.
