The sound is not working even though I unplugged my headphones.

Try plugging in and unplugging headphone to the headphone jack. This model has an intermittent problem with the headphone jack that makes the receiver think there are headphones plugged in even when there isn't. Inserting and removing a plug sometimes clears this.

If you don't plan on using the headphones - take the cover off and there may be a cable to the headphone jack board that can be unplugged. This will disable the headphone jack from sending a bad signal to the micro. If you want to be able to use the headphone, then the jack is going to have to be replaced.

This is the normal way for this laptop ..leave it always with the headphones on selected in that list ..cause if the main speakers don't work well there is no point in using them ..This way you will run whatever yo will plug in ..speakers or headphones..The only setting difference in headphones and stereo out ..is that for headphones will but the speakers of the laptop when plugged in ..This way it will even help you if the speakers are making weird noises cause they are damaged ..

Hi depending on the design some receivers , when you plug in headphones, speaker sound is disconnected by the headphone socket so it could be faulty, or there may be a separate switch to switch of the speakers, (while using headphones) if so that switch could be suspect. I dont think the amplifier part of the receiver is at fault as you say you can hear sound at the headphones. It is not impossible though that a fuse has blown inside the amp, If you unplug from mains and look inside you may spot a blown fuse , (only replace with one of the same rating).
Hope this helps

This worked for me (this solution was posted on another thread). Unplug the base and take out the headset batteries. Wait 30 seconds. Reconnect. Turn on head set. I could hear immediately!

psp sound your headphones problem

sounds like your headphone jack might be out unless the sound is comming out from the headphone jack when plugged into the pc

I had the same problem... but I knew that my 2 yr old had been playing with the headphone jack on the BC-150. Evidently, the system thought that headphones were still plugged in to the port on the front right of the unit, even though none were present. The solution that worked for me was to take some headphones, plug them COMPLETELY into the system (another set of headphones would not insert all the way, so I found a new set and used those to completely insert into the headphone port) while playing a CD and listen for a few seconds and then simply unplug them. Viola! Sound came back. Hope this helps.

Try plugging back the headphones and unplug them agai, but

pull them slowly.

Replace the NiMh batteries. They might be bad. Could happen during power surges as you indicated you had. Let them charge up fully 14-18 hours as the book suggests.
