Compaq MV 540 (old dog monitors) DEAD 100% DEAD.
OSD dead too. it seems.
built in year 2000, its 17 years old, and you fix things that old
why> why do that, used LCD can be had for 20 bucks.
why slave over any relic CRT like this,,, for a musiem??
using the VGA cable
the monitor will go to sleep, lacking any PC sync lines Vert/horz
by design per VESA rules on that !
step one , use a PC.
set the PC up to do the max resolution on the CRT
some PC cant do that, (new PC)
im reading your users guide now, 1sec, google , hit.
first force the PC to 1024x768 resolution and 60 vert. refresh max.
now the CRT can work an not any of above number higher .
see? use working monitor to do that FIRST.
now plug in the vga,cable last. on the monitor under test.
power led means
green = power ok
amber or yellow are sleep or standby.
so that means, there is no sync.
or if the OSD works (does it>) turn the silly sleep timer off in the monitor. via OSD .
the operators guide, tells you to go to PC safe mode.
this mode sets reso real low. 800x600 and all monitors work there.
no sleep timer inside monitor i can find.,
lots of ways for any CRT to fail even the CRT itself
(loss of sweep)
loss of cathode video drive
the VGA card inside, can fail. killing dead all cathod drive.
the power supplies or regs inside can fail.
the HV can fail. 10,000 volts (dont touch it if long life is good)
some survive, or fly back hit head on wall and crush skull,
seen it and done it so,,, there you go.(ripped gash in arm once)
the 2nd anode is very high voltage, avoid it, and win,.
respect it.
it could be th epower supply and it could be the monitor.
power ON button should not flash orange regardless what you do. it should stay green. then orange. not orange to green to orange.
try the monitor on another PC if you can fine one.
the other thing is are the 2 monitor similar (CRT to CRT and LCD to LCD), you can't mix the the two, they will work but need different video driver to function correctly.

my compaq crt monitor not showing color. its shows only blue, green colors . u please tell me. what is the problem in.how to solve it.
is the monitor fault or any other.
SOURCE: compaq mv540 monitor does not come on when i turn
in a technical language you can say its a display problem. the monitor is fine.its actually the problem inside the pc.either some connections are loose or the ram memory needs to be cleaned or some part is gone faulty which needs to be checked.if any of this happens the display wont come.check all the above possibilities to reach the cause and solve the problem. please do rate the solution,thanks.

have you tried going to menu and setting back to factory defaults? also, disconnect power cable and leave unplugged for 1 minute. Plug back in then see if problem is still there. Otherwise, something is wrong with the monitor that will need serviced or exchanged.

As far as the cd drive goes, get that replaced cause with the door closing and shuttin on its on, it could broken pieces of debris in there thats causing it to do that or the board inside of the cd drive is broken so either way replacing that would solve that issue.
As far as the USB ports are concerned, try hooking up other USB devices such as a USB keyboard, USB Mouse, flashdrive. Try other things to see if you get the same thing, if you do then that means the motherboard is bad cause all of those ports connect to the motherboard.
As an alternative solution to try, if you don't have anything important to save off of the hard drive, you can restore your computer back to factory defaults and then try the usb ports again and if they still dont' work then you know for sure the motherboard is bad. At that point you can replace the motherboard or find a USB card that plugs into one of the PCI slots. That would give you other usb ports to try.

Power Window System Controls
The power window system will operate anytime the Retained Accessory Power (RAP) system is active or when the ignition switch is in the ACCY or ON position.
The driver master control switches are integrated into the DDS. When a power window switch is activated in the up or down positions the DDS supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the DDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist and during window motor operation the DDS continues to monitor the motor current to verify proper window motor operation.
The DDS controls the passenger window by a serial message to the PDS. When a power window switch is activated in the up or down positions the PDS supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the PDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist, and during window motor operation the PDS continues to monitor the motor current to verify proper window motor operation. (Scan tool support is available for this system
Check this circuit breaker
RETAINED ACCSRY PRW BRKR 30 amp. located in the left instrument panel fuse box . if the breaker is good check power B+ at the drivers door switch . connector 1 terminal b yellow wire . Sometimes the wires inside the rubber boot coming from body to door break .
