Do you still have the Nokia? Did you ever take the cover off to inspect for bad caps? Bad caps didn't just happen to early 00s PCs - they hit almost everything. Lots of electronics, TVs, STBs, converters, wall warts, etc. from the period can be resurrected by a peanut sized investment in a few caps and some soldering time.
