This is not a DC power supply problem. You most likely have a fault in the Vertical deflection circuit of your TV. You will need to get a qualified technician to look at this.

Hi, in Antec 300watt power supply there is 3 cables or input or current 220volt. The cables are Black, Green and white. Which one is earth, which on is live(positive) and which one is negative?


For 120 volt operation use
black for the hot, White for the natural, Green for earth ground.
For 240 volt operation use;

Black and White for the 240 volt and Green for earth ground.
Black is generally designated as the "Hot" or "positive" .
You must make sure the switch on the power supply is set for the voltage you are using. ie: 120/240

I need to find out where the 3 little plugs go that are connected to the power button theres a blue/white black/white red/white plugs comming from it going to the motherboard


Sometime these connectors from the desktop case front panel have labels indentifing what each connector/plug is for. From your description they could be a reset switch or LED indicators for hard disk or power light etc.
If the plugs are not labeled then trace the wires back to the front panel to identify what they are attached to.
When you connect the LED indicators to the motherboard and it does not light up when they suppose to, then turn the plug around 180 degrees.
The LED are polarity sensitive ie they only light up if the + and - leads are connected to the motherboard correctly.

Need to up grade Components


Almost all of the newer power supplies use the black connectors - and generally come with one or two white connectors for older hardware. The best recommendation I can give you is to open the box and make sure the power supply will fit inside your computer, and the screw holes match the ones on your old power supply. Other than that it's normally a fairly easy process to change power supplies on newer computers.

Dell Inspiron flashing amber power light, not charging


I would think the batteries need replacing. That happened to my Dell Latitude CPI. The batteries won't charge past about 3%, so I got new ones and that did the trick. If this is under a year old I would contact Dell about it, if it is under a year old they should replace the batteries.

Hope this helps.

Have T5026 emachine with boot problem


Sounds to me that theres a good chance that the windows files are corrupted. It is possable that its could be hardware, but software is free so start there.

If youve got the recovery disks then put them in and restart. Just attemp a repair of your windows. its worth a shot. you may need to go into your boot setting to boot from disks.

if you havnt got them and you havnt got warrenty them youll have to format the drive and install a fresh copy of windows, and find all the drivers from the emachines after.

1st get all the stuff off the drive that you need/want, take the drive out and connect it to another pc or use some sort of external connection.

then find a copy of windows that matches the licence sticker on the case of your pc. throw the hdd back in and boot the disk, format the drive and install windows.

youll have to get the drivers from

how to fix a power supply if the white copper is no power

Codegen 450w model :200x


Run a jumper wire between your Green wire on your 20/24 port plug that would hook to the mainboard and one of the black wires in the same plug. I would put a pushbutton or switch in between the Green and a Black on that plug. You may need to put a load on the power supply like an old hard drive or a CDROM. Plug your power supply in and you will notice the fan turning. Use your multimeter to test for different voltages on the connectors. You should get +/- 12, 5, 3 Volts.

I just went into my basement and tested this out and it works great.

Enjoy
