This is a problem related to the hue controlls in the TV. It is quite common.

Fix: You can go into the TV settings and try adjusting the hue/tint there.

If adjusting settings does not work, request help from a technician to fix it for you since it will take adjusting the hue internally and if you do not do it correctly it can damage your television.

I hope this helps ya!

yeah, I have the same issue... The tv worked fine, and now it will not turn on... the light turns green, then turns off and goes red...

I would suggest replacing the board itself, chances are what caused those fuses to blow is still faulty. did you check those fuses again after you powered it back up?
