Okay; first off an SMPS is any number of power supplies used for electronics. So this is a very vague question. In a computer power supply to an IBM or PowerPC based motherboard (the later is now obsolete and no longer in use for most new computers) there is no one power supply "wire". Most video cards are powered via PCI port through the motherboard power supply connection.

Some very high power high end video cards and some SLI/Bridged cards require their own power source and this is usually a 12 volt rail much like the ones used for SATA power supply.

In a monitor, each make and model can be different depending on who supplied the power supply. The internal power cords can come in different colors. Though the standards are black white blue and green and red. Most displays don't use colored cords for connecting to the main board of the display. They use a 8 or 10 pin ribbon. Most of the colored wires are linking the main inducer to the LED back light.

If we're talking about the internal workings of an SMPS (Switch Mode Power Supply) there is no "display" wire. SMPS internal wiring is all about controlling and routing power to the different rails (that is the different power connectors). Never open an SMPS case, especially if it's plugged in. Switch-mode power supplies have capacitors that can provide a rather nasty charge, and several inducers that can hold a charge well after the power supply has been unplugged. Never service an SMPS on your own, always seek a professional when attempting to fix an SMPS. Though, for the most part, fixing a burnt out power supply is a waste of time, it'd be best just to buy a new one and recycle the dead one.

The display panel appears to be your problem but i would replace the video inverter too when you replace it.Replacing just the display panel should do the trick though.

Faulty Display


It could be a bad connection in the wiring between your display and the keypad. You should get it checked out at a cell phone store especially if it's still covered under warranty.

No beep,No Display on my monitor,only CPU heatsink fan is moving


hey
there might be problem with SMPS also. I mean there is one signal comming from SMPS - Power Good
if that singal is not comming then machine shows this kind of symtoms.
To check Power Good from SMPS -
Requirements ->
a) small wire/ pin
b) Multimeter
Procedure ->
1) Disconnect all power supplies going OUT from SMPS.
2) Locate the Orange Wire , Green Wire, Blackwire
3) Now insert small pin / wire into Black + Green wire (Make them SHORT) and provide power to SMPS --> SMPS will get started.
4) Now check the Multimeter rating for Orange wire --> it should not be less / more than 3.3 - 3.6 volts. --> If it is less / more then there is problem with your SMPS and you need to get it repaired.
5) In india it will take near about 100-150 Ruppes to repair SMPS.

alternate ->
You can replace your SMPS with other working SMPS (best option will be your friends system) and check whether same symptoms occurs or not.

Other Damedge -
If SMPS is working fine then there must be problem with FEW SMDs available on your motherboard. For this repairing in INDIA it should not cost your more than 600-700/-
