Having problems with your HP f2105 21" LCD Monitor ?

Monitor's backlight inverter shuts down.

\015 After a minute or so the inverter shut's down, so no light, and no picture.Turn off and on the monitor brings the inverter back to work for a minute or so.I turned the small potentiometer on the inverterboard, there seems to be a little influence on the time.Seems that there is a component overloading protection misadjusted or so.Does anyone have a schematic on this board, or an idea how to save 90 bugs to buy a new inverter?Many thanks.Marc \015

Hi,

Initially, visually inspect for any leaked or bulging capacitors. The problem may be heat related. In the absence of a schematic diagram, you may have to wing it. To verify if it is heat related is to have a can of compressed air or "instant freeze". Soon as the unit shuts down, spray suspected area. If unit resumes operation, you have pinpointed the area to start component check. If it is a major problem, the unit will not even start up. But since it works except shuts down, then again as initially posted heat related.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
