My top screen is blank. Any suggestions?

When the 3ds xl turns on I get a flicker on the top screen so I know it is getting power. The screen has slight glow so I think this suggests the backlight is on.

Everything seems to work but the top screen stays blank.

I have replaced the top screen but the problem remains.

All the connections appear to be good and I saw no obvious damage to any cables when I was replacing the top screen.

I made sure the WiFi board and the other small board are correctly on the motherboard.

I am baffled as to the problem at this stage. Does anybody have any ideas?

Thanks

Hi,

Make a visual inspection and look for any sign of humidity in the motherboard.

Some times it will be more expensive the labor of investing more than 2 hours looking for the root cause than the repair itself.

My advice, whole cleaning of the motherboard and if possible ultrasonic treatment to remove any sulfation in the components.

If required apply a good flux and heat (heath gun mid power) 2.5 mins p/side.

Good luck and good repair.

JM
