Question about Audio Players & Recorders
My new Bose Wave III is losing time on the clock. The display will read "Please Wait" as if it was powered back on, and then loses time on the clock.This happens several times a day while plugged on, but not when playing the radio. I have checked the chord connection and outlet connection, unplugged and replugged and lastly a reset to factory settings. Nothing helped.

Actually the problem was caused by a bad 470uf cap, that was used to filter the powersupply for all the analog amps. Replaced the cap the unit works like new.

SOURCE: Bose wave radio won't turn on
Unfortunately Bose will not release their schematics or parts lists, effectively giving them a monpoly on repair of these units. Their web site, www.bose.com, offers to repair most Wave radios for $100 or to provide a $200 allowance towards purchase of a new Wave. Before you spend the big bucks on theis trouble-prone product though, you might want to check out the new HD radios -- better sound and MUCH lower prices than Bose.

There is a fuse you can check. Also a rectifier bridge, a 3 terminal regulator IC (18V in, and 10V out) as well as a small transistor Q1 which often shorts. Easy and cheap fixes, or I would offer to buy your non-working model Bose if you decide to sell it.

open unit up and check A/C FUSE located near where the A/C plug/wire is connected to radio!
If fuse is bad it will measure an OPEN ]---- ----[
a GOOD FUSE will measure a SHORT ]-----------[

I have the exact same AWR1-1W model for repair last week. I am assuming you have a meter and you also have soldering skills here.
You might want to check the Q4 transistor (2SC3792) for a short on the two outide pins. With the power disconnected, measure with a multimeter the resistance between the two outside pins of the Q4 transistor. If you measure anything between 0-3 ohms it is shorted. Replace this part with a similar part or you could replace it with the new Bose recommended part - 2SD438F-MP-E but it is very hard to obtain. I have used an 2SC2655 instead and had no problems so far with the radio. This radio also came in totally dead with no display nor the radio working.
