I need your help. What are the big yellow areas on two of the phal's leaves? And if you know what it is, please tell me what to do. Thanks!

Yep. Notice how the pattern is continued on the next leaf. The damage is done; it is entirely internal, so no secondary infection will develop, so do nothing. Eventually, those areas will turn parchmentlike.

Phalaenopsis plants should never see direct sunlight.
