I recentyly replaced a cracked touch-screen on my ipad 3, however, i found that the backlights on the righthand side is not working. The screen on the lefthand side is more brightnes than the righthand side.
Did anyone know how to fix it? Thank you.

Try to perform a hard reset by holding home and power button for 20 sec.
Maybe that will help. : )

This issue is caused by accidentally shorting out a backlight coil, IC, and/or filter while removing the LCD ribbon cable. Remember to always turn off your device before doing any repair work or if possible let the iPad battery drain fully. I have learned this by making a couple mistakes myself...

I think the connector is no problem, I've cleaned with a special spray and the problem persists, I performed the reset and still the same.
It may be due to the quality of the replacement display, which is not adequate?

found a better detailed solution, there are 3 types of ICs involved.
coils tend to be more resiliant than the filters, the smaller black square types above and underneath need testing. make sure to test continuity with a voltmeter as well prior to

Mine were L2200 & L2210 : ) Main cause is the price of rice in China these days.
You guys can send me stuff, I'll fix it.
Yes. You fix it by replacing the backlight filter.
Send it to me. I'll do it. Sounds like you are lacking the 4k in equipment & knowledge. It's not something you'll get right without a few years of training 1st.

Why 4k when a temperature controlled iron will suffice to remove and replace a emi filter bead and diode? This is a two minute repair.
hey man are u still fixing this issue? i think i shorted the backlight on an ipad 4 when i was taking out the ribbon cable. i used metal tweezers by accident. please email me at reedmohornnc@gmail.com

Had the same problem. I noticed that after restarting, the Apple Logo would be evenly bright at the beginning and then half of the Apple would dim. Figured it might be a software problem so I updated to the latest OS.
Worked like a charm. Hope it helps you guys as well

After replacing the screen on my ipad 3 the right side was slightly dimmer. Because everything else about the repair worked perfectly I've been hesitant to disassemble it again. I think this may have something to do with the display cable connector. Perhaps the cable isn't seated properly.

This problem also happens to me, I tried the solution provided, but not solved. It may be due to a hardware problem in the motherboard of iPad 3?
