Digital TV to the red and yellow three lines how to pick up After picking up the color is not normal pink
Hello, Americans like the Japanese fear of being dead, so the computer is only 120V. You buy power in the United States does not apply with China, easy to burn. Recommended to the domestic Apple store to buy an AC adapter, that is the white 4 square things. =============== But when the purchase may have to give you 240V, so you'd better take a look at your instructions on the cows. There is a number of vouchers.
Now gives a digital multimeter to determine the breakpoint of the wire and cable method. When the cable or cable inside the disconnection failure, due to the external insulation of the package, so that the exact location of the broken line is not easy to determine. With the digital multimeter can be easy to get this problem. Specific methods: the breakpoint of the wire (cable) one end connected to the 220V mains of the FireWire, the other end of the vacant. The digital multimeter to AC2V block, from the wire (cable) of the FireWire access side, with one hand pinch the black pen pen tip, the other hand the red pen along the wire insulation skin slowly move, then show The screen displays a voltage value of approximately 0.445V (measured by the DT890D meter). When the red pen moves to somewhere, the display shows a sudden drop in the voltage of 0.0 to 0.7 watts (about one tenth of the original voltage), about 375 px from the position forward (FireWire access) Cable) breakpoint. When using this method to check the shielded wire, if only the core is broken and the shield is not broken, this method can not be measured. Digital multimeter in addition to the voltage, current, resistors, capacitors and transistors and other basic parameters of the measurement, but also through the use of change, so that its function has been further expanded to achieve a multi-purpose purpose.
I do Lenovo brand machine, I have encountered the same problem, your computer is unable to add a graphics card with an independent power supply, the motherboard can not give the power supply to the graphics card, there is no such wire, replace the power supply is not OK , Because the motherboard is generally 20 +. OEM board is 14pin, unless you can find 20 to 14 motherboard power supply extension cord, or is not used (power is not 4PIN power supply interface)
