Well, I discovered my lifetimed Series 3 has a couple of domed caps on the power supply, so I'm looking to replace it - the power supply, that is.
This is the TCD648250B model, the OLED, and the part number for the power supply is apparently SPWR-00008-000
I am aware that I could replace the caps myself, but I can't solder with reliable enough quality to risk this - thanks, lousy fine motor skills (not).
I could seek a local electronics shop, but quite frankly most of the small electronics repair places in my area that I've found (for other electronics repairs) charge $100 minimum to touch anything, usually with some type of "bench fee" before they will even speculate whether they can do the work.
This leads me to think of hiring someone online to do the repair, but that introduces the possibility of shipping damage, and before I go that route, I thought I would see if anyone might have a spare power supply that they'd be willing to sell.
