Lost my 'off' ' button on my Proton 320 clock radio!

What is wrong with it.

when you set the alarm it is activating by itself ...see that you have the button that will set it to go to radio or buzzing noise..and in the back it has a knob for a separate volume on the alarm I think this is what you have lower and the alarm is not heard even if it kicks in ..
let me know if that is the issue or I should see further ..

Unfortunately, Proton discontinued these a very long time ago. There is not very much information available about them. The cause for the radio malfunction could be a number of things. One possibility is the switches. There is a foam gasket around the switches that degrades over time. If pieces of it get stuck inside the on switch, or lock the off switch, it would prevent the radio from working. You could try taking it apart and use a can of compressed air to clean out the switches. I had a problem with the radio turning on all by itself and the compressed air cleaning solved it.

It sounds like the tuner is out of alignment. A number of things can cause this kind of problem. However, a realignment is a very costly proposition, especially when considering the used value of the Proton 320. If you really like this radio, you might want to try buying a used example off of eBay. They come up very frequently. Only... be selective. Don't pick anything from a seller without a lot of good feedback. And don't overpay ($50 tops).

The tuning module within the radio is getween the base circuit card and the display. A shot of tuner cleaner into one of the ports will usually bring back the FM performace (I just got done diong my own). Also, it goes without saying that you need to make sure your radio still has its antenna wire and that the vacuum didn't eat it. If this is beyond your skill level, find a computer geek (there are few radio geeks any more). Commercial repair would cost more than the value of the radio.

check power switch if not block and i good position. and also monitor by multitester if the continuity of that switch cut in off position.

The bulb is a small electronics bulb on the left side of the lexan display cover and it is covered with an insulated foil tape. Measure the voltage on the bulb with a voltmeter and go buy a replacement from any electronics supply place or radio shack.

The battery is located on the display circuit board at the front of the unit. It's a bit of a pain to get to.

You'll need to open the case, unplugging the wiring harness plugs so you can take the two halves apart. Next, remove the strip of circuit board at the top where the snooze/alarm and other top button switches are. Then you will be able to get to all of the screws holding the display circuit board to the front of the case. The battery is soldered to the board. I'm not sure what type or voltage it is, but it's probably a single-cell NiCd at 1.2v. I think the best replacement would be a supercapacitor but I need to figure out exactly what the battery is first.

It's a great radio that's worth fixing. If anyone can tell us what the battery is, please post! Mine says "860" on it.
