Crate gtx 65 guitar amp mains hum
I had the same problem on my VTX65. I noticed it would oscillate with different effects so I removed the effects module. Problem solved. Now it's dead quiet. I use a Digitech RP500 so removing the effects module was a non issue.

Hi chupetin2
If the problem is present with ONLY the speakers connected, that is no other powered devices like subs, or input/output cables, it will be a power supply problem inside the amp. If you have electronic fault finding skills, there will probably be a capacitor in a regulated rail that has failed.
If you do have a sub connected, be sure it is powered from the same mains source as the amp, or at least a GPO that is on the same phase. Different phases will induce mains hum, as will multiple earths. Try also temporarily moving the amp(whilst monitoring the hum) from where it is sitting and see if the hum is being induced into the amp by any other devices
Happy to talk to you more about this. Just ask:)

My p47 bluetooth headphone doesn't input any audio from my chromebook
There could be a few reasons why your headphones are not working with your Chromebook. Some possible solutions include:
- Make sure your headphones are fully charged and turned on.
- Check to see if your Chromebook's Bluetooth is turned on and that your headphones are paired with the device.
- Try restarting both your Chromebook and headphones.
- Make sure your Chromebook's operating system and drivers are up to date.
- Check to see if there are any known compatibility issues between your headphones and Chromebook.
- Try resetting your headphones to factory settings
- Try using different headphones with your Chromebook to see if the problem is with the headphones or the Chromebook.
If none of these solutions work, you may need to contact the manufacturer of your headphones for further assistance.
How to set time on acint27wm

I have a Fisher ca-9335 receiver/amp ..Problem is
It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be your output drivers- the MOSFETS/IC's fitted for both the channels, Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise like a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.
You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board, maybe the protect circuit by itself is shutting off due to a faulty bias , maybe a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the protect is off then check for short on the speakers.
HI, my qt6600 freeze not working i try to turnoff and hold button but still not working
You may be experiencing an issue with your QT6600 freezer. If the freezer is not working and you have tried turning it off and holding the button, there are a few things you can try to troubleshoot the problem:
- Check the power source to ensure the freezer is properly plugged in, and the outlet is functioning.
- Check the thermostat setting and ensure it is set to a low enough temperature to activate the cooling system.
- Check the condenser coils and make sure they are clean. If they are dirty, clean them with a brush or vacuum.
- Check the evaporator fan and make sure it is working correctly.
- Check the door seal and ensure it is tight and not letting in warm air.
- Check for any error codes or flashing lights on the control panel, and consult the user manual for troubleshooting instructions.
- Check the compressor, it may be overheated or not working correctly, and this could be caused by a faulty compressor or a lack of refrigerant in the system.
