THis is a problem of the invertor board.If you are technically able you need to disasseble the monitor and resolder components around the red or yellow inverter transformers.

Monitor keeps going blank - when im on internet it will suddenly go extra bright for a half second, the blank. if I switch it off using the button on the side and switch it on again, it just goes blank...

loricaney, Do some research first. Go here: I just read a comment that some guy wrote. He stated that he aquired 30 Vs17 non-working units from a high school, and that 25 of them had bad (swollen or leaky) filter capacitors. The other 5 had cracked lcd panels. maybe $6 in new capacitors will restore unit for you. Do some reading in my fixya profile and "budmrtn" and "buddymc" fixya profiles. let me know if you want to do a DIY repair after you do research and visit YOUTUBE for video clips of owners doing typical capacitor removal and installation. 12fixlouie

My hp pavilion F1703 monitor goes blank about every 30 seconds.

Thsi model has known problem with bad solder joints due to contamination, you need to remove the old solder on the four inductor leads, clean the leads eal well and resolder, see my pictures here:
Al so look to see any one of the capacitors have bulging top, they should be completely flat top.

Pavilion f1903 silver goes blank seconds after turning on.

The monitor you have has bad components on the circuit boards inside.
This is a classic problem with all LCD monitors.
I rebuild them on a daily basis so I recognize the symptoms.
I would suggest finding someone who can do component level repair on the circuit boards inside.
I also suggest not trying to repair yourself as there are many breakable components to them as well as components inside that do not like static electricity discharges.

Hp flat screen monitor

It's probably your dc power supply.

Mine would blank just 2-3 seconds after power-on.
I pulled this monitor out of the garbage - someone threw it away. I found any old 12vdc power supply I had laying around (1 from an hp scaner 1250mA, another rated at 600mA) neither could supply the current (amps) required to run the backlights, therefore backlights shutdown, monitor goes blank--monitor stilled powered on, but black.

I tried all of the disassembly, re-solder various solder joints on the LCD Inverter board and removing the heat/magnetic shield from inside the back cover of the monitor. Nothing worked.

I bought a Segate 80gb external hard disk drive that came with a 12vdc power supply, looks like a typical laptop power supply, rated at 3A (3000mA). Plugged it to the monitor, it powered up, and it works flawlessly.
