Why will my Joey not Turn on?
Why will my Joey not Turn on?
Check the power cord Make sure the power cord of the DISH receiver is plugged into the wall outlet (typically has a red tag). For a Joey, make sure the power cord on the back of the Joey is connected tightly as well.
What happens when a Sony amplifier is on standby?
When the amplifier is on standby, this circuitry is always providing power so that you can switch the unit ON with your remote control. On many Sony amplifiers, the standby voltage is 5.6 V. It provides power to a small microcontroller chip on the front panel. It also powers the infrared module.
What to do if your Sony receiver has no power?
If you do not know what you are doing, it is extremely dangerous to remove the cover and check inside the unit. There are lethal voltages present. It is better to take it to a reputable, professional electronics repair centre and ask for a repair quote. Was this answer helpful?
What should I do if my Sony amplifier wont start?
This article is for times when you are absolutely sure that there is no fault in the audio power output stage, and the problem is elsewhere. The Sony STR-DE375, STR-DE475, and some STR-DEXXX range of amplifiers tend to have a standby board that is often the focus when I am starting my diagnostics.
What causes the Sony receiver to go low?
As you can see, there are also a pair of clear glass signal diodes that provide partial rectification. The current from this is used by the AC detect chip NMJ2103 which checks for abnormal power. The detection of abnormal power results in pin 8 of the chip going low close to zero volts.

What should the voltage be on a Sony stereo?
Make sure that your device is set to the correct voltage for your area. Some devices have a 110 to 220 voltage switch where the default setting is 220V. Verify that this switch is set to 110V. Press and hold the POWER button, and unplug it from the wall outlet at the same time.
