Hi all, looking for some help with my Tandy 1000HX.
I tried to power up my HX the other day, hooked to a CRT Television with a video RCA composite cable and am getting no proper picture.
There are no error beeps on start-up, unit seems to power up fine. Power light comes on and stays on. 3.5" drive light comes on and stays on Number lock and Caps lock lights respond to their button presses.
Screen, however, is black with garbled white lines. These lines could be the white Dos text scrambled or could just be interference, I can't tell.
I've tried hitting F2 when starting the Tandy to see if that will restart TV mode with no luck.
I've also tried typing MODE TV once the computer has booted with no effect either.
I made a video of the booting process for reference:

Unfortunately I have no Tandy monitor to hook it up to test and see whether or not it is only the composite output affected.
Hoping you can offer up some advice!
Thanks,
Rory Lambert​
