Question about HP Pavilion F1903 19" Flat Panel LCD Monitor

1 Answer

Going to Sleep

The power supply to our PC (eMachine) recently died (our outside powerline was hit by lightning - which also blew the PC surge protector). We replaced the PC power supply (ourselves) and now the (F1903) monitor states "Going to Sleep" and goes into a power saver mode (solid amber light) almost immediately upon being turned on. If I'm fast enough, when it first comes on I can hit the Menu button on the monitor and see the menu, but it quickly goes back to "Going to Sleep" again.

We've tried unplugging (power) and re-plugging. We've connected the montior into a laptop and gotten same results. We've replaced the monitor cable and gotten a "Check Video Cable" message. After plugging the monitor into another computer (laptop) we've got the same message.

The monitor is out of the warranty period.


The monitor keeps saying going to sleep, no other option is offered.
I have unplugged everything and switched everything on and off and it still says monitor going to sleep

Due to the power surge, it is highly possible that the monitor was given a boot by your computer on it's way out.

This will short out a very small transistor inside the monitor on the video board and in turn, then monitor cannot see that there is a signal so goes to sleep.

If you get brave enough to venture inside the screen, then check near the cable input. The transistors are only around 3mm and have 3 legs (two one side and one in the middle on the other).

If you find anything like that burnt (get a magnifying glass) then replacing the board is the easiest option. Just don't be tempted to wipe the board before you look at everything very closely, you may wipe away the tiny bit of evidence you are looking for.

Hope it helps =)

Monitor going to sleep


juanmgerman0, Connect SDM-X82 to known-good pc that has all sleep mode, power-save mode disabled. (turned-off) If unit still goes to black screen mode, then look at the "date of Manufacture" on rear of unit and let me know if you see "2002 -2004" as the year produced. Retrevo lists unit as "time to retire". Power supply may be going into shut-down mode having detected a problem with itself or the CCFL inverter circuit. 12fixlouie

Try it on another PC, but more likely to be the problem in the power supply. Please post back when you try it on another PC.

Screen bleeds into white after coming out of sleep mode. Turn on an off a couple of times and screen is fine. Is it my video card or is my monitor dying?mag FP-2226AFW 22"


guest, FP2226AFW may have internal "switch-mode-power-supply" problem. Swollen electrolytic filter capacitors or "thermally fractured" component leads to printed circuit board solder joints that will need to be "reflowed" to restore unit to normal operation. Prove that problem is monitor by swapping-in a known-good monitor to your pc first!!! If pc is ok, then 2226AFW unit will need "tear-down" and Inspection" of it's "switch-mode-power-supply/cold-cathode-fluorescent-lamp INVERTER power supply printed circuit board. Do some reading in my fixya profile and those of other CCFL back-lit lcd monitor tech's and you may just find a solution. All CCFL back-lit lcd monitors of the same basic design and functional operation. 12fixlouie

Monitor just went off. no power light. changed fuse but monitor is completely dead


possibly a power surge killed the main board in the LCD. if the fuse was blown i would suspect a power surge. you could replace the circuit board. either that died or the power supply died- depending on if it has internal or external power supply that might be blown as well.

i would take it to a professional LCD/ LAPTOP repair person. they should be-able to test it and let you know what needs to be replaced

Replaced my power supply, now keyboard and monitor wont work.


Believe it or not, if you have a floppy drive in your computer, try unplugging it and disconnecting the data ribbon. Many times, damaged floppy drives can short out motherboard functions and even prevent computers from powering up. If that doesn't fix it, then get a usb keyboard and mouse set (wireless would be fine) or borrow some, and see if they work. If they do, then the power outage damaged the PS2 ports.
