Question about Dell E172FP 17" LCD Flat Panel Monitor
I know that i need to replace the transistors(All 4 C507) .Where do I buy them? Do I need also the inverter transformers and the FET which drives the transistors.
Monitor quit working shut off while using ,Try to restart and the power button just blinks green.
My solution: I searched many posts. My LCD also went black after 10 minutes or so, and green led was still on. Then i had to press power off and on to display again for minute or 2. I used reset function in its osd. And problem is gone! Yai!

There are a couple of people on ebay selling them. That would be best bet. You may only need to replace the bad one and it's partner.

You have to measure these parts with a multimeter to decide if they need to be replaced or not.
You have to measure for shorts. Replace the components that measure shorted.
It is unlikely you will need to replace the transformers. Resoldering them wouldn't hurt though.
And, I can't stress this enough, check all the capacitors first. 90% of the time, the faults are caused by bad capacitors.
As for where to get them, you will have to call around town to all the electronics parts supply stores and see if any of them can supply the transistors or a substitute. If not, you will have to find them on the internet and order them on-line.
