Yeelight 450 YLXD04YL yellow color problem

I was using this model over 1 year, and now it suddenly lost yellow color. White and white-blue are ok, but yellow is lost at all. When i configure lamp, via smartphone, to light at 100% yellow, it doesn’t light at all.
I did firmware upgrade after problem appears, but it didn’t help.
Is possible to somehow fix this issue, or it is some general hardware problem? May be i may try to replace fuse, if there is any?
