Re: Dell E172fpb

Hi everybody..
Short description: I replaced 9024 & 5707 but after 2 minutes they burn again (one 9024).. I decided that one working ccfl will be enough.. My plan is to desolder failed 9024 - this will disconnect faulty circuit for second ccfl.. Whats happened: LCD working fine but backlight is getting off after 2 seconds.. I think i need to put feedback1 (IC751) from working circuit to disconnected circuit feedback2 to cheat IC751..

What you think?anybody
