LCD - Backlight missing some illumination

Just replaced the digitizer and on re-assembly I've noticed the bottom edge of my ipad has four dark patches. Looks like some of the backlighting LED's are not working? Could it be a single damaged filter connecting the LCD connector? Looks like there are 6 LED drive connections off the connector, so just wondering if I have blown a filter?

Cheers,

Matt

I guess the only way to really know is too try a different LCD. The LCDs are pretty fragile. Could also be connector damage, but try a different LCD first then go from there.

It was the filter - one of the 6 was o/c, therefore losing a string of Led's.

http://www.cyberdocllc.com/wp-content/up... Replaced one of the 6 filters (labelled as Resistors) as shown on this photo in the green box. These 6 Filters connect to the LED Strings in the LCD, so if one goes down you lose a whole string! :-)
