Thanks, they both look identical except for the Rev #'s, so I guess I will try it out.Did both power supplies come out of either a TCD652160 or a TCD658000?
If so, they are interchangeable. Even if they're 2 different brands.
But if one came out of the original Series 3, the TCD648250, the one with the clock display, you'll have to know how to remove the gray wire from the motherboard plug and insulate the end because the 652 (HD) and 658 (HD XL) do not use that 7.5V line and we don't know what it might short to.
Power supplies from a Series 1, 2, 4, or 5 won't fit and won't have the right connectors.
