I concur with the solution route indicated by Louie Role above. I have a similar problem with our H/K Play & Go Wireless.
The problem in our case could be isolated to simply a bad power connection at the back of the unit, which connects to the 18 Volt high current DC source.
All kinds of strange problems occurred such as not being found at all as a BT unit, faulty connections, also that it may work at low volume but you get dropouts at higher volume settings. It appeared as if the unit has "power" (power button was white) but not enough amps to drive it fully or even to establish BT connection sometimes - requires quite a lot of current this little monster :)
Our temporary fix this evening is to just make sure the connector has some physical drag to the side to ensure sufficiently low contact resistance. This fixed the problem 100% so I'm sure this is the problem. Also tested it with a car battery and an 12 => 18v converter and it worked just fine, here the power connector was slightly narrower than in the original power source.
I'll fix this tomorrow by disassembling the unit and replace/adjust or re-solder the power terminals at the power connector. Not sure just cleaning the contacts will work since the connector feels a bit wobbly and this is not ok for this application - needs a really solid contact to deliver the required current to this powerful little music machine! Fantastic value I must say, we love this unit still after so many years so very happy to be able to bring it to life again!

Hi and welcome to FixYa,
Appreciate the direct "Ask Me".
Initially, pls try cleaning the battery terminals. In some instances, it may be necessary to scrape them to remove corrosion. Still there are times they may have to be bent or stretched to ensure that they provide more pressure to the batteries. Alternately, pls try to confirm that the AC adapter is working by checking for the presence of voltage on the plug/connector with the use of a voltmeter.
Should the above not address your concern, then it is most likely that the problem is internal electronics and the unit is simply going into protective mode. You then have a choice of performing a DIY (do-it-yourself) or seeking the services of a qualified professional.
Good luck and Thank you for using FixYa. Happy Holidays.
