300mA is marginal. On CD start unit draws a little over 400mA for about 1/2 second. At moderate CD audio levels the unit draws right at 300 and at full volume 400mA.
Be certain of the polarity and voltage . On the unit I have the wire with the white stripe is negative. If you are using a non-regulated supply, the voltage could be higher than rated. I am using a 9.5 volt non-regulated supply and after input filtering I have 11.5 volts across the input cap, that is rated @16VDC
A non-regulated 12VDC supply will probably exceed this 16VDC
rating.

I have a Behringer xenyx 802 audio mixer and have lost the power supply. I tried to buy a replacement, but cannot find any in stock. I'm very resourceful and thought I'd make one. The spec sheet calls for...


No, you can't just jump the pins together. The power supply in the mixer needs two separate 18-volt AC inputs because it makes two supply voltages, +15 and -15 volts.

The external supply is just a potted 36-volt transformer with a center-tapped secondary. I bought an open-box Behringer (not your model, but similar) that was missing its supply, and found this transformer which works fine. (I actually did find a couple of sources for a replacement Behringer supply, but it cost more than I paid for the mixer!) Just connect the three output leads to the appropriate places on the mixer's PC board. In mine, I removed the original input connector and soldered a pigtail with a 3-pin connector from Radio Shack to the PC lands, then attached the matching plug to the transformer leads. You'll also need to provide an enclosure of some kind to prevent contact with the line voltage input to the transformer and to protect the thing if you carry it around.

I need a schematic plan for this unit. Where can I find one?


You are extremely unlikely to find a schematic for this. Why do you need one? Your best bet is to just replace the power supply. The replacement cost is very low.

Best of luck, Jim

Check your current rating on the OEM power supply.. I think your power supply needs 2 amps at 6 Volts. The cheap ones at radio shack are usually only 2 ma.

Need to find replacement padapter no. JoD-41U-02 for pro-2018. Can't locate one. Do you know where I can buy one.


The exact replacement power adapter for your scanner is out of production. Power requirement for the PRO-2018 is 12 volts with a minimum of 300 mA. Radio Shack has a universal power supply that will work, or you can pick one up on eBay for under $20, including shipment. You can also pick up a voltage-specific power adapter on eBay or elsewhere, but you may have to change the DC plug to match your scanner.

My HP photosmart 2710 will not turn on. There is 31 volts going into it??


Option 1

If you have a blinking light try changing cart.

Option 2

If the unit is blackout change the power supply. Here are the specs

Power specifications

* Power consumption: 75 W maximum
* Input voltage: AC 100 to 240 volts - 2 A 50-60Hz, grounded
* Output voltage: DC 31 volts === 2420 mA

I unplugged it and now it wont turn on after I plugged it back in to the wall outlet


The exact same thing happened to mine several days ago. I opened mine up, noted that two of the capacitors on the power supply are a bit puffed up, and tested the power supply's 12V and 5V outputs. The 12 Volt output is fine, but the 5 Volt output is only putting out 2 Volts. In short, all of the capacitors on the power supply are made by the same company (Jenpo) and apparently these capacitors were made using the stolen but incomplete formula for manufacturing capacitors much more cheaply. That "capacitor scandal" has cost electronics manufacturers millions. In any event, this would explain why Walmart blew out these Cyberhome CH-DVD 300 players for such a cheap price. Obviously all of the capacitors on the power supply will eventually fail. I have already experienced similar capacitor related problems with a few computer motherboards and other electronics equipment which I bought in the early to mid 2000's. I am contacting Cyberhome to see if they will send me a replacement power supply to go in my CH-DVD 300.

Usb problems


Due to current (amperage) limits of batteries, most laptops have VERY small current caps on USB ports. Some desktops can have 1-2 amps per USB port, but laptops are often limited to 300 to 500 milliamps. This is sufficient for most memory sticks/pen drives, but many USB devices need much more power than that. For example, external USB-HDD cases for 2.5 inch hard drives will need 100-200 mA ABOVE the rating of the HDD, which is usually 500-750 mA. Few laptops can provide that much current, or will initially provide enough to spin up, but get errors or fail to mount due to lack of power. If your USB device has a secondary power jack, use it with a 5 volt AC power supply with the correct jack polarity and current rating. You can also try a "double harness" USB cable, which plugs into the laptop with TWO USB jacks, and into the USB HDD case with one (the third) jack. This allows TWO USB ports to "double" the available current for the USB device. Best to get the specs on your laptop, see what your USB current limits are, before doing this. If each port is limited to 300 mA and your HDD is 500 mA, you will be OK, but if the HDD is 750 mA, the total of 600 mA is not going to spin up the drive.
