I have a Dell Dimension E521. When I cut the power on everything comes on including the monitor, but the monitor will stay black. It does say something about power save hit any button but the screen


A solid green light means the computer is operating normally.

A solid yellow light indicates the power supply is operating normally but the computer is not processing data.

This could mean there is a problem with the CPu or another component on the motherboard.


((A blinking yellow light indicates the power supply is receiving power from the wall, but not functioning properly.
This generally means the power supply itself is bad and should be tested or replaced.))


A blinking green light means the computer is in standby mode.

You should consider visiting Dell Support and downloading the manual for your

your Dell computer. So use the LED power light codes if your Dell computer has them.

hope this helps

Vaio desktop blinking power supply


Remove the side pane to access your motherboard cables, etc. Locate the connector on your motherboard that contains the wires going from your power supply to your motherboard. It will be a large, rectangular connector with a lot of individual wires It is not a ribbon cable but should be located next to a ribbon cable connector and next to a green blinking light on your motherboard (when the power supply is plugged into the wall). Note: This green blinking light is in addition to the green blinking light on the back of the PC.

This next step is important: You have to disconnect the connector noted above from the motherboard WHILE the power suply is plugged into the wall. Wait a few seconds and plug it back in. The blinking reen light on the motherboard should now be a solid green light. The PC should now power up.

If the steps above don't work you will need to get a new power supply.

Connect power swithc and led cables to foxconn n15235


Still have your Foxconn manual? Turn to page 19. See figure FP1.
Download manual from Foxconn, click on the link provided;

System cases vary when it comes to wire colors. The most common wire colors for positive are, solid blue, light blue, solid red, solid green, light green. Negative wire colors. Each led, IDE-LED, Reset, PWR-LED and PWRBTN should share a negative colored wire. Common is the solid color white but this can vary from case to case.

Good luck!

Dell dimension 2400 blinking amber light


1. Remove All External Devices
2. Check the Computer's Power LED
3. If the power LED has not changed unplug the Power Cable From the Computer Disconnect All Hard Drive Power and Data Cables and power on the computer. If still no go.
4. Remove All PCI, PCI-E, and AGP Expansion Cards .
5. Remove All Memory From the Computer
6. Reseat the ATX and 12-Volt Connections . The ATX connector will be a 4 pin square connector connecting to the motherboard from the power supply and the 12-Volt Connection would be the biggest connector with a lot of colored wires.
7. If still no go.
8. Disconnect the Power Connection to the Chassis Fan
9. If the light still flashes then it could be a power supply or motherboard failure. Try a good know power supply first and if that does not fix the problem it is the motherboard. Also check the back of the tower for 4 lights lables ABCD or 1234.
Rate if useful.

HP won't power on at all~PSU light blinking, then solid, then off


Dead short on the machine causing the power supply to go into shutdown (Fold Back Protection)

Remove all of the connectors coming from the power supply (Label them so that you know here they go back to on the Motherboard and the DVD etc (Including the processor fan one)

Place all of them back one at a time starting with the main one if the led stays on then plug in another till you locate the short.

If the led dies when you plug in the main MB connector then you are in deep brown stuff

All you can do then is to remove the Ram and any other unpluggable device to see if that is the cause

QPS-525 usb CDRW - quit working. Pwr Supply OK.


Check to see which LED is blinking, the one on the cdrw or the one just below it showing theres power to the enclosure? If theres proper power to the enclosure the green led light below the cdrw should stay solid green. If you have a blinking led light on the cdrw itself, you may wish to disassemble the enclosure and ensure all the short wire leads to the converters pcb are still properly connected and that theres nothing loose. Make sure the IDE cable is properly seated as well as the molex power connector.

A blinking led on the cdrw may signify a problem with the drive itself, since it should not be blinking unless its being accessed by the computer. You could also try reloading the drivers for it whether youre running it on a mac or windows machine. Perhaps change the usb port youre connecting too as well. Before sending the enclosure to the trash, try another cdrom drive connected inside of it. That should be the definitive test to solve whether its the fault of the enclosure or burner itself. Hope these troubleshooting tips help.

Power Problem


usually blink code on front gives direction but first thing to do would be to determine if surrounding sustain boards are causing draw on power supply by disconnecting them one at a time from power supply. y is on left looking from back and x is on right looking from back. if led goes solid with either board disconnected check supply voltages and if come up and stay up replace that board. if no change then you would need to verify vs on command coming from logic main to power supply. should be labeled on power supply connector and should be 3 volts. if present replace power supply if not present verify if logic main board sitting underneath signal board has one solid and one blinking led on if verifying normal operation and if so replace small signal board

Flashing Green Light on Power BESTEC Power Supply


This is an easy fix so here you go nice and simple:

Problem: Your motherboard circuit has been cut.

Causes: Power disconnected during operation. Power outage or short in the surge protector.

Symptoms: Flashing green light on both motherboard and power supply. System will not power on.

Solution:

Step 1: Ensure that both the power supply and the motherboard lights are flashing green, not solid or off.
Step 2: While the power is on, disconnect the power supply from the motherboard. This connection is the largest of the connections and should be listed as the 'P1' or 'Primary' power connection.

Step 3: Wait until the green light on the motherboard stops flashing and check to ensure that the green light on the power supply is now solid. If it is not solid, disconnect the power to the power supply and wait until the light turns off completely. Then reconnect, it should be solid now.

Step 4: While the power is on, reconnect the P1 connection to the motherboard and you should now see that the light on the motherboard is solid.

Step 5: Power on your PC. The problem should not persist.

Warnings: If the power supply light remains flashing after you have restored power to it while it is disconnected from the motherboard, it may be a system failure in the power supply itself requiring replacement. Always be careful when working with an active or live power machine.

I hope this helped! Good luck!

Ok 7 red blinking led, remove the back cover of the TV. Looking at the power supply in the upper left of power supply. If everything is working fine you will see a solid green led if there is an error, you will see this light blinking also. Right below this led on the power board you will see a list of numbers 1-13 this will give u the problems that this led flashing problems are. More and likely u will have a problem with VSET or VSCAN. Which is connected to the Y-Main and Y-buffers,( the board that is too the left of the power supply if u look on the small print on this board you will see that it reads. 42HDV4 Ymain and the 2 small boards connected to it are Y buffers. To be sure that this board is bad if the TV keeps going into error protection. unplug the power supply and wait for the led to stop flashing. Disconnect the cable that plugs into Y-Main from the Power Supply. It should stay running. If u remove this board and look underneath u should be able to see where this board is getting hot. Easiest fix is to order a replacement. Y-main assembly.
