  • Re: Dell E172fpb



    Yes as I said it is just dim looks similar to a CCFL or an inverter going out in a laptop, but with a few seconds delay... Thanks to self test technology we don't need a computer to test screens anymore not even that crazy little box that makes rectangles with the 9V battery. Planning on pulling transistors and checking them with the huntron tomorrow should show me the correct graphs I guess I will start there even if they have capacitance or something else inside skewing them from their normal working area.

    Yes, both screens show...

    Did replace caps at least the 470micro ones as thats what I had in stock.

    Transistors checked with no shorts.

    Checked solder points did add solder to a few spots that looked iffy

    I actually have another dell screen here same setup but with same problem, but it is a E172FPb. I haven't had any luck with either board/screen....

    I think from the posts this may not be the best screen to work on...

    My symptoms are screen turns on displays the dell test image red green blue white moving box then goes dim. I have recapped the 5 470uF 35V caps transistors do not show shorts I have retouched all the solder on the board as well. I am at a loss at the moment seeing as how no caps are bulging even the 5 I repaced weren't leaking or anything. What part of this circuit should I forcus on? Here are images of my board the blue caps are the replacements....
