Old “AT” PSUs usually don’t need anything to trigger them ‘on’, but they might need some load balancing across the various taps. Usually done (quik-n-dirty method) by whacking on a bank of ceramics which dissipate 100-odd watts or so.
But the main problem is voltage… most of them supply only about 11.5V under load. Chargers like a clean 12V+, preferably 13.8V.

I’ve got a tv to fix, and just worry that the capacitor might still be charged…
Heh… leave them off for 30mins and all the caps should be pretty drained, even the flyback ones.
Unless its a simple job like dry joints or an dessicated capacitors, old TVs are hard to fix. Can’t get parts, can’t get schematics…:evil:
