Since I'm new here I see a lot of activity so I hope someone out there can help me out. I have this Tandy 1400FD Model 25-3501. It powers on, floppy disk drives do its seek test, keyboard lights work, and the Built in LCD monitor backlit DOES work because it lights up a kinda dark blue and its not dimming. And that's as far as I can get. No text on display, the floppy boot disk boots into dos, I know that because the floppy drive continues to read the disk as it loads. But No text on display. I checked everything all the way down to the capacitors, power supply is getting a 11.6-11.9 Volts across the board, even under load, the contrast knob doesn't have any effect. I get 2 short beeps indicating RTC battery is low, I checked that and its more clean then anything else retro I own, but I still should see text right? I cant find anything on how to fix this.
