Why it always blew, then you have a short circuit. It is not your fuse is the real problem because it is a guard to your unit. Once there was a short circuit it will blew to avoid further damaged to some parts. It is commonly due to a shorted parts on the power supply section. You must isolate the shorted parts to back your unit to normal. If you are not a technician then you must look for a qualified one to trace the shorted parts. This will fix your problem.
