Re: Compaq Monitor

Sounds like a short somewhere inside of it. Check the resistance across the 2 post on the power cord with a multimeter. If this reads an extremely low resistance, then I recommend taking it to someone in electronics repair. Or getting a new monitor. You could also check to see if there are any blown capacitors. These look like little trash cans and if any are open at the top or look like they are leaking some type of liquid, they will need to be replaced.

Why is my refurbished Compaq WNG monitor going off?

From the description the problem is in the power supply board, there are probably one or more bad capacitors that have opened, sometimes they bulge at the top making it easier to spot. If you hire a shop to repair this they will charge, and on top of that the monitor is at least 5 years old before you got it, I would replace the monitor.

A menu keeps flashing on my monitor so fast I can not read it and it will not stop. Black box with grey edge. Compaq 5017M monitor

mrsrobins849, if monitor manufacturing date (on rear of unit) is anywhere close to 2003-2004 then trade unit for new wide screen only if problem of flashing "menu" goes away when you connect a borrowed substitute monitor to your pc. Will your monitor "act" same when connected to "known-good" "fully-booted" pc that will display the WIN-desktop?? Most problems with "cold-cathode-fluorescent-lamp" "back-lit" lcd monitors can be attributed to their internal or external "switch-mode-power-supply" DC voltages degrading over time with use.

Compaq 21'' monitor power supply led is not working

Flickers until all monitor area turns gray - just like tv without signal

Sounds to me like bad caps on the power board or main board.

The monitor is faulty for sure. Bring it back to the shop and tell them the problem is still happening and ask them to leave it on connected to a computer overnight since it takes a while to happen. They should see it happen and then troubleshoot it further.

Your HP notebook PC probably has a VGA (aka HD-15) connector. Check page 16 of this PDF to make sure - connector #2 is the VGA connector.

Your Compaq monitor also has a VGA HD-15 connector, so it should plug directly into your laptop's port after unplugging it from the other PC.

You will still need to plug the Compaq monitor's power cable into a wall outlet for power.

If you are going to share this monitor between your notebook and the other PC, you may want to consider purchasing a Keyboard-Video-Mouse switch (known as a "KVM switch") - there are many different models - you will need one with VGA, and whether you need USB or PS/2 keyboard/mouse connections depends on what your other PC's keyboard and mouse are.

Compaq FP 5315 monitor-Replacement of Power board

There are also 5 or 6 bad Capacitors on on top but as far as i know the only way to fix these power boards is to replace the componets themselves as you can not buy a power board.

Compaq FP 5315 Monitor Disassembly

This is how I did it.

1- Remove the four screws in the back of the monitor. Two are in the bottom corners and two more near the bottom center ( these hold the stand in place).
2- Remove the stand.
3-The case back is held on by the four screws and a number of plastic pressure clips. After removing the screws: using a fairly wide flat bladed screw driver; insert the blade in either of the two slots on the bottom edge of the case and twist with medium force. This begins the seperation of the back from the rest of the monitor. As the crack widens, begin moving the blade of the screw driver along the widening crack (around the case edge) and twisting gently. This releases each pressure clip in turn. Separate the case back from the rest of the monitor.

I did this this way with my monitor. It works.
Good luck.

Monitor keeps turning on and off

OK All these Compaq's have a Power Supply problem, or a Horizontal Voltage problem.. meaning they are on the way out. The SMPSU's in these units often fail along with the Horizontal Drive Circuitry. I think it is time for a new one? Repair of such a unit would barely be "Ecconomical" IMHO.
