Another out of interest comment is that I had one of these cheap DVD
players with exactly those symptoms and replacing caps restored it to
perfect working condition despite 19 V on the 12 V line, or was it the
5 V line? Chips are tough.



Years ago I had a TTL logic board in a video game that would only run if the
5V supply was cranked up to around 7.5V. Ran it like that for years, never
did find the marginal part(s).
