Wii Yaosm3.2 - Can play old backups, bl;ackscreens on new original games

Hi,
I had my Wii chipped a couple of years ago with Yaosm3.2. I've been able to play backups fine until about 2 years ago when the backups started to just blackscreen after selecting them from the menu. It still plays the old backups I made such as wii sports resort.

I recently bought Tiger woods 12 The masters and even this original disc blackscreens. Could anyone advise what to do or where to start reading to help me fix this please?

Thanks,
Dan

Boom! Solved it.

And now it works, not sure which part was the crucial bit but it works.
