Power surge blew fuse - cut off all power - radio clock turned on when i jumped the fuse - did not check radio yet - need to determine correct replacement fuse - and where to buy it - the board shows a diagram indicating correct placement of fuse with the following specs "75A 250V " .
I have the same problem. To get to the circuit board remove all the screws from the bottom of the Wave radio. At least that is what we did, but ours is a really old model. There are two screws if you are looking from the back to the front on the front right corner that secures the bottom to the interior chassis THROUGH the circuit board. Careful! if you unplug all the gang connectors and those two screws are out it will come apart. My question is Where is this blown fuse located on the circuit board? I have two glass fuses in fuse holders that are ok.

I have had several different makes of clock radios and all said that it was battery back up for power failure
none worked and all settings had to be redone
power surges do not trip breakers as they are in effect a fuse to prevent damage to the wiring in a dead short situation or when a unit fails
even surge protectors will still pass power after a surge but will no longer protect against another surge
If you're lucky, you blew a fuse. If you're not, you blew a transformer. Either way, it will need to go to a service center. However, ask for an estimate as it may be cheaper to just replace it than fix it.
Check your car's owner manual to learn the location of fuse box. Locate the fuse in the fuse box that powers the radio. Check it and / or replace it with the size recommended in the manual (the clock is probably powered from the same fuse).
Since your radio appears to be an after-market type, it is difficult to know how it was wired / connected. Most installers prefer to use a "wiring harness kit" between the radio wiring and the car's wiring; as no cutting of the car's wiring is required and the radio can be wired to the harness kit at a desk or table instead of having to do it in the car. Regardless of how wired, the fuse in the car's fuse box may not be blown or open - there is probably a fuse (or two) on the power wires for the radio as well. Many radios need a switched power source (so the radio shuts off when the key is off / removed) and an unswiched power source (to maintain the station presets and clock when power is off). Check and make sure both fuses are good - replace as needed.
If still unable to get the radio / dash clock to work, you will probablyu need to carefully trace the wires and connections to make sure all are proper and tight. If you do not know if they are in the right place after tracing them out - you'll need to bring the car to a shop and have it done professionally.
There is a good chance that this radio got a power surge which may have been caused by the power going out and then when it comes back on, there is a surge. In some cases, a "brown out" does more damage than a surge.
For example, if a telephone pole fell over and the power lines were arcing in your neighborhood, your lights may flicker for several minutes. This can damage many electronic items in your home.
If this clock has a battery backup, try removing the battery and replace it.
If there is no response, you may want to take it to an independent electronics repair person and have him check the power circuit.
Chances are that the circuit board behind the ac power cord will be damaged.
Hi. Often following a power outage there is a power surge when the power is restored. If you do not have your Bose protected by plugging it into a surge protector, an internal fuse will blow to protect the rest of the radio. Once that fuse is replaced you will be back up and running. J.
Yes - although Bose doesn't really publicize the fact, there is an internal line fuse in each Wave. Location varies by model and date of manufacture, but the fuse is easy to spot once you open the radio case.
Is the unit under warranty? If not problably a fuse. take unit a part. main power pcb located on left side towars rear. remove scews holding it and have a look there. these are typically pico fuses labeled f1...f2 etc. Check for continuity with a meter if blown it will say OL if ok should read 0. Fuses and are available at your local electronic store.
The fix may be as simple as replacing a fuse. Location varies by model, but each has an internal fuse on one of its circuit boards. SAFETY NOTE: It may seem obvious, but be sure to disconnect power from the set before you open the case.
If the fuse is not the problem, you will need to seek professional repair. Unfortunately, Bose does not release their parts lists or schematics, effectively
creating a monopoly for parts and repairs. In fact, their web site
says that the Bose factory is the only option for service or repair.
They used to list a flat rate repair charge on the web site, but
removed it - probably because it scared too many people. Their
troubleshooting guide (below) might help, but it's very simplistic.
Before you invest in expensive factory repair on one of these trouble
prone sets, you might want to investigate the new HD radios -- better
sound at a MUCH lower price.
