Re: HP L1740 Lcd inverter/power board
All,
Strange problem with the my first inverter/power supply board. I re-capped it and installed into the monitor. Upon power up the Windows 7 logon screen shows for only about 10 seconds (green power led stays light constantly) and then goes out. I have a bright light on my desk and I can see the windows logon screen still. This is the same problem with this monitor and it's original inverter/power supply board. I removed this board and found only one blown cap. I took a another capacitor (same kind capxon) from another power supply board and then reinstalled the original board.
Turned it one and it does that same thing as the newly recapped power supply board.
Windows displays for about 10 seconds and goes out (the green power led is still lit).
I have reading other posts about other monitors, could this be a problem with the CCFL's??? Still new to troubleshooting these monitors. Thanks for all your help so far.
George
