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?

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.

Update (04/13/2016)

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.

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.
