    I cannot get the player to turn on. I plug up the adapter to the cigarette lighter as provided in the package and hook the DC in for both units, turn the units on, but NO POWER. Any suggestions????

If you are not using the car power adapter that came with your PDV-768 for the 2nd screen, you are likely running into the possibility of "reversed polarity" with the power adapter you are attempting to use. This can & often will cause a problem with your unit.

I was also looking for the manual. So came across this site. I have just connected a 12V 1A DC charger to the 12V DC input socket. Seems to be working fine. Both green lights are on - I seem to remember that when only the right-hand green light is on, the unit is fully charged. If I find my manual, will correct if needed.

How to make 12v DC power supply to power my winch

use a 12v car battery and a small battery charger... a winch draws alot of amps when in use... so you need the battery to supply the amperage ... 12v power supplies are low amperage output supplies... so will not work (inexpensively).

Connecting speakers to a pc

The 12v dc power supply is for the speakers. There should be a spot for it on them. All modern PCs use power speakers, since the sound cards have no amplifier.

I have a black & decker pivot plus that will not charge. How do I know if I need a battery or if I need a charger?

Batteries are only good for about a year, if they are older than that, take them back to the store and see if they are guaranteed at all, (all Ryobi tools and batteries have a date code on them, and they are all guaranteed for 2 years, a little plug for Ryobi,) that is all I buy now days, they work great. So, to check your charger, you will need a volt meter set on 12 or 20 v dc, and see if the charger is putting out, if not, then, the cost of a new ryobi might be the same as the fix for the black and decker. That is if you use the thing, we use our cordless tools every day and charge them every night, hope this helps.

Cannot find the charger for my vectorlite 1.5

Hi sast.
I found this on amazon: HQRP AC Adapter Charger for Black Decker VEC119SH TYPE 1 VEC120 TYPE 1... It says that fits, but anyway contact the seller and ask.
Hope this was helpful.

Start up light flashes once and it won't power on

Most probable cause is the power supply. Look at the back of the computer, check the voltage settings located near the power cord. This will be the small red tab indicating two different settings, If your in the US it should be set to 115. Also, the power supply should run the internal fan when it is turned on.

To test the power supply try this:

Open your computer case and locate the gray box that is the power supply unit. Trace the wires from the power supply to the boards and devices and disconnect all the cables by unplugging them.

Find the big connector plugged on the the motherboard, make sure it is disconnected and short the two pins: (GREEN & BLACK) Short green pin (14) to GND (any black) to switch power supply ON, disconnect green from GND to switch OFF.

This will switch the power supply, you should hear or see the fan in the power supply spin. If you do not see the fan spinning, and your sure you have shorted the correct wires, you have a faulty power supply. If you see the fan spinning, you can now test the voltage coming out of the power supply.

Place a volt meter on the following colors to test voltage:

The color code for the wires is: Red = +5V, Black = Ground (0V), White = -5V, Yellow = +12V, Blue = -12V, Orange = +3.3V, Purple = +5V Standby (not used), Gray = power is on (output), and Green = Turn DC on (input).

Power coverter to scanner failure.which unit should i buy? present one 240v 50/60hz.0.4A. output 12v.dc.i.25A

I just found my Canon 5000F scanner to have a power supply outputting 3V DC instead of 12V DC. I replaced it with a 12V DC Power Supply from Tandy rated at 1.5 amps. I had the scans getting darker by the day and sometimes completely black. Now I have great scans again. Just test the voltage at the plug that supplies the scanner for a healthy 12V DC with a multimeter.
