I've repaired about 10 type Bose AWRC3x (the radio/cd model with lift up lid and top controls). If the cd won't play or skips, try cleaning the lens VERY carefully with a cotton bud with some isopropyl alcohol. Let it dry then try again. This will help in about 1/3 of cases.

After that, a new laser unit is needed. They cost around 15 pounds,30 dollars, (Type SFP100s with 13 pin connector made by Sanyo). You need to have some electronics experience to take the case to bits to get the laser deck out, change the cd laser and reassemble. Basically, DISCONNECT THE POWER! Remove the 3 screws on top, turn over and carefully prise the front of the base away from the top cover with a table knife or similar. Lift off the top cover - be careful with the lid ribbon! The deck can be disconnected from its ribbon cable and wired connector very carefully. Take the deck to bits and fit the new laser head (take photos if you think it will help). Remember to unsolder the shorting 'blob' of solder which protects the new laser from static till its fitted.

On the bright side, there is no tracking etc to set up, that's all automatic so usually they work like new with a new laser fitted. I have to say this is the weakest feature on the Bose CD radio, the actual electronics rarely gives trouble.

Hope this helps Steve O'Donnell

Same problem here but I could not find the Q401...do you know where I can find a schematic that could help me locate it?

SOURCE: My 10 year old Bose wave radio quit working.

There's a line fuse inside the radio, mounted on a PC board. CAUTION: disconnect the set from power before opening the case or poking around inside. The fuse could be bad, but these sets are notorious for losing the power transformer. If the fuse is ok then you are looking at a $100 repair fee from Bose. You might want to check out the new HD radios -- better sound, MUCH lower price.

I repaired mine recently. Check transistor Q4 for an e-b short. The replacement costs less than $1.

Amplifier chip/circuit is kaput. Unless you are familiar in fixing electronic equipments better to give it for repairs................sodeep
PS. Buying a new one will not be cost effetive unless you need a change!
