There is no way of fixing it. The only way is to get a replacement

Was that first picture taken after the lens melted?
It looks fine to me.

For the diode, u can try to decan it. As for the lens, the only way is to change it

thanks for those info. will try it soon.. for the lens.. i think metal housing for it is the best way to avoid from it melting again...

about the driver, is it okey if i use the host and change the components only?
