My StyleWriter II (which I've had since new) stopped turning on about 2 years ago. I'd press the power button, and nothing would happen. Turns out the power supply was cactus...swapped in one from my busted SWII, and I was back in business. If you can't fix it, or find another SWII to scavenge one from, keep an eye out for a Canon BJ-200, they were essentially the same printer, my guess is that the PSU is probably the exact same part.
