Hi all I have this 25" I-INC that i replaced the CCFL lights and then it worked for like 3 months then 2sec to black.
I found that one of the driver smd mosfets were shorted and i replaced it.
now the pled well stay on and backlight go out and i get a humming or buzzing when there is no backlights are on. but for the short time the back lights go on the buzzing goes away then comes back when back lights go out.
sounds like its coming from smps you know the big yellow one. when i look at some of the outputs on my scope i see that some have solid line (dc) and some ac and dc thats what it looks like anyways and i had my scope on dc settings. i well get photos soon.
thank you for any and all replys
