Checking the inverter board and CCFL lamp for a HP ProBook 4530s Notebook PC running Windows 7 Professional
external monitor shows the different accounts on the notebook. The user can log-in to the account and use it. Other days, the
notebook monitor works properly and everything shows up properly and user can use it without issues. I estimate something is malfunctioning with the inverter board for the LCD or the CCFL lamp on some days. There was no diagnostic tools which came with the laptop
to check those parts.
1. How can I check if the inverter board for the LCD or the CCFL lamp are working fine or not?
2. Is there a software utility I can use to check them(inverter board or CCFL lamp) before I open the LCD?
3. Can something else be causing the issue?
I notice http://www.laptoprepai
is faulty(lamp or the inverter board)
The laptop was purchased in Oct 2011.
Any suggestions would be appreciated.
