Dwanlesso6, Please tell me brand of monitor and if it is LCD/FPD and size 15,17 19 etc. If it is an LCD then it is possible that the DC power supply and or inverter board has failed. Here is short PS101 lesson. All electronic things (Stereo, printer, radio, computer, TV,) all require DC voltage. You get AC Voltage from outlet on wall. the two don't mix. ever!! All the above mentioned things have AC to DC power conversion circuits. They are called power supplys. Only your's and everybody's LCD monitor has two. One makes DC for the monitor logic/digital kinds of stuff, 5.0volts and also makes a
\015\012second and higher voltage ( 12v or 15v or 24v) to send to the other power supply which is called an inverter power supply. The inverter PS changes DC into a higher frequency Square Wave AC voltage to power up the Fluorescent Tubes that make your display "bright white" !! Do you own any of those new style light bulbs. You know... the ones that look like small coiled fluorescent tubes and screw into the same socket that previously held the old filiament type of light bulb. Well your dealing with the same technology in your monitor. Just for kicks, you can go to www lcd-monitor-repair. com. Don't pay any attention to the 'advertisement' !!!! just look at the pics of what is inside an LCD/FPD.
\015\012The advert just wants you to buy books on LCD/FPD repair.. The best advice I can tell you is try to locate some repair shop that specializes in FPD troubleshooting&repair. Hell, I too am waiting for this 19in GatewayFPD to die. Hope is later.. not sooner, or I'll be in same boat w/LCD/FPD for anchor. Good luck.
