Testimonial: "if you try to phrase "dc power board for cameras" you will get the power strip that feeds the entie camera system. what im looking for is a 1/3" motherboard that accepts 12V then power the camera inferred led and the camera board itself"

Have older rca xl 100 13 inch tv and can`t seem to get a picture with a hd cctv camera the tv wirk find if I hook it up to dish net work. the power supply is a 2 amp 12 volt system and using wire with...

Is the HD CCTV camera analog compatible? I would imagine not if it says HD in it's name. But you can try using a converter box with it because if the camera is outputting HD you need to convert it to analog which the TV can understand.

I have a desktop PC that when I turn it on it will power up and then after 6 seconds turn back off.

The first solution is right on the money, It's the video card, or many of us today forget to plug the damm thing in and the computer doesn't read and we think that there is a serious problem. If none of this helps then try troubleshooting through this PC repair guide. Hope this helps.

You press the button and it donest turn on all the time



Inside an SMPS, (Switched Mode Power Supply), are Electrolytic Capacitors.

(Radial. The bottom capacitor in the photo)

Electrolytic Capacitors slowly build up a charge, then release it all at once.
You can compare it to a large swimming pool being filled up with a garden hose, and then one wall of the pool being taken down all at once.

At the bottom, of the Radial (Style) Aluminum Electrolytic Capacitor shown in the above photo link, are two leads.
One is Positive, the other is Negative.

Touch your finger/s to the terminals on the bottom of one of these babies, and the shock can be BAD to FATAL!

If your fingers touch, and complete a circuit that one, or more capacitors are in, the shock can be BAD to FATAL!

Don't open that power supply!

Besides, a fuse goes out All At Once.
There is no work a little bit, then turn off.
It just goes Poof!
(The fusible element inside burns into two separate pieces)


"You press the power button, and it doesn't turn on all the time"

As has been suggested, I also concur that you have a bad power supply.

But you could also have a bad Power On switch, located inside that plastic Power On button.

This is an example of a Power On switch, that I have found fits a lot of computers,

I'd like you to get this switch, and install it.
From there the diagnosis will go to the Power Supply.

Also would like you to make sure the ram memory is seated tight, and the Processor fan is spinning, and looks to be spinning at the right speed.

If the fan spins a few times, and stops, then spins a few times, you know the fan has a bad bearing. Replace.

If it looks to be spinning too slowly also, you'll know it

Be sure to follow anti-static precautions before you reach inside your computer, and the computer is unplugged from power.
If you do not know what anti-static precautions are, I'll be glad to tell you. Simply state so in a Comment.
(Believe upper right of your page)

As for the Power Supply test, you need either a multimeter, or a power supply tester.

An inexpensive multimeter, that will work just fine for this application, ranges from $6 to $12. The Voltages are only 3.3 Volts, 5 Volts, and 12 Volts. (DC)
Two C cell flashlight batteries are 3 Volts. (DC)

Your computer power supply puts out three main Voltages, as stated above.
A) 3.3 Volts (3 point 3)
B) 5 Volts
C) 12 Volts

Orange insulated wires are 3.3 Volts
Red wires are 5 Volts
Yellow wires are 12 Volts

ANY Black insulated wire is a Ground wire.

This is DC Voltage.
There is a Positive, and a Negative.

The Positive (Red) probe lead of the multimeter touches a power wire. (3.3, 5, or 12)

The Negative (Black) probe lead touches ANY Ground wire. (Black)

IF, the 12 Volt power rail shows 11 to 13 Volts, the diagnosis indicates the Power Supply to be good.
(However read on)

IF the 12 Volt power rail shows 11 Volts, or less, the Power Supply is bad.

This is an example of a power supply tester,
