Backlight/LCD problem
« on: April 11, 2008, 02:50:22 PM »
well...I took apart my slim...I did the trigger mod/UMD jewel/LED mod, and wifi/mem/power/charge swap...all to Green...also sound sensitive with LM386 and wired to wifi switch...anyways, when I tried to test it(before I put it back together) the power LED come on, and the trigger/UMD LEDs come on when I turn on the switch...but the screen doesnt work...I thought it may have just been a brick, but then I realized its probably not since the backlight wont turn on either, but I dunno...seems like the screen would still come on(but VERY dim) if it was just the backlight....but I could be wrong....anyone know what this is/could be

any help will be appreciated...thank you so much^^

Try holding it up to a light to see if you can see anything on the screen when it's turned on.
