Does anyone have this problem with their 790cc? Has anyone else noticed this with their adapter?

They all do it. It's the transformer hum, and it isn't indicative of a problem. Braun should have addressed this design flaw prior to releasing the electronics in this configuration. They should have switched to a different transformer, or at the very least reconfigured the charging circuit. That high-frequency noise drives me crazy, but I have learned to live with it. What really makes me angry is that the "LOCK" button for the shaving head is a piss-poor design, and the pin that locks the cam has broken on me. I am not jumping through hoops with Braun service, so I'll rig an alternate pin. For this kind of money, I expected the same Braun quality I have come to appreciate over the last 20 years.

I have the same problem, have had the unit for about a year and this began happening rather abruptly. I purchased the Connector suggested in another answer but it did not fix the problem.

no problem from getgo all 3 speeds w/ the one I got a couple yrs ago. If u r mechanically inclined check all connections. My speed control switch on low has been finicky a yr ago - no problem since. The medium & high positions really move air. Other choice is return f/ swap. Sorry to hear of this bummer & frustration.

Not sure why this happens. I have not had the issue at all. Maybe a cable winding issue with the specific cable in your set.

I had the same issue but I had to adjust the external air baffle and now it works great. The external air baffle is right under the regulator.

I didn't have this issue with this product but I have had this issue in my home with another adapter. I had to call the company that I use as my internet provider and have them turn off the hot spot in my home. The hot spot signals were conflicting with my Wifi signal causing the computer to have an unsteady signal.

I got the same error when I tried using an ac adapter that was too small. I purchased the tenergy 12v adapter and it worked perfectly. I hope this helps.

Could be a number of things. You could have damaged the adaptor port with the different plug causing a bad connection. Blown a circuit or fuse. If the power adaptor you used was a lower voltage, you may have done nothing, a higher voltage may have damaged the electronics. A volt meter to check the adaptor voltage and to check the circuit would be a good place to start. Check to make sure you didn't damage the port and try the correct adaptor again. Good luck.

I don`t know what is wrong... my starts in 390. Are you using the right voltage?

Thought of something else. Make sure your power adapter is set to the correct polarity + -, mine is set at +

Nope had same problem once went to aaa wave.com and ordered a 3000 rpm fan shaved the little plastic off new fan plug and it will work back perfectly. I would just switch one intake to exhaust and have front open using a small fan blowing in there until repaired

I successfully installed this adapter in a Dell Optiplex 7010 SFF, don't have a 790 to check unfortunately.

Nope. My BRX2400.1D have been working just fine. Sorry to hear you're going through this. Probably just a bad apple out of the batch

...whoever you bought it from...may not respond favorably. Why not try jiggling the connector from the motor to the board? It's what I did when I got the same prob. Loose connection...

I do not have that problem at all. However, heat is a major factor for all amps. Are you mounting it where it gets more heat than air? What kind of bike and and where is it mounted. I have a harley heritage and mounted mine right under the headlight. stays cool and never cuts out. good luck.Also.. it might be that yours is defective. exchange it and try again. Amazon is pretty good about swapping things out.
