Question about HP w1907 LCD Monitor
My HP w1907 monitor will randomly go to sleep and a message will come up "monitor going to sleep" and will shut off and jiggling the mouse or hitting the keyboard will not make it wake up, the only way to wake it up is restarting my computer manually by pressing the power button. this happens every 30 mins - 1 hour that I have my computer on.
ONE OF THIS SMALL INTEGRATED CIRCUIT FEED THE LAMP WITH 15 VOLTS AT 40 000 HZ ONE OF THESE IC'S IS FAILING SO YOU NEED TO BUY THE IC AP9971GD -TO REPLACE,pLEASE CHECK IF THE BOARD AROUND ONE OF THESE IC'S IS BURNT OR BROWN AROUND IT TO KNOW THE FAILING IC. THE DESCRIPTION OF THIS IC IS N-CHANNEL ENHANCEMENT MODE POWER MOSFET - Advanced Power Electronics Corp .OTHER SOLUTION SHOULD BE A SMALL LEAK INSIDE OF ONE OF THE INVERTERS. BUT IN THIS CASE YOU NEED TO REPLACE WITH THE SAME COMPONENT. BECAUSE THE IMPEDANCE MUST BE THE SAME FOR THE OUTPUT HIGH VOLTAGE CIRCUIT.tHANK YOU AND GOOD LUCK:http://www.alldatasheet.com/datasheet-pdf/pdf/248903/A-POWER/AP9971GD.html

Check your owners manual for the power saving controls. In this section this should explain how to stop the monitor from going to sleep, or at least allow you to to set the timing for it. If this does not work visit the HP website and search the common problems for your model of monitor. search for this problem and the solution.If all this fails, seek help from HP technical service. Hope this helps.
