Need help on DB Systems POWER AMP repair.

One of the mono blocks does not power up at all..Need suggestions or any one who has expertise repairing DB SYSTEMS amps.Thanks
That's amazing! I have a DB-6 amp in the closet. I wonder if it's worth having it updated.
check the fuse first! it should be located on the back panel. if it's defective, replace it. see what happens. good luck
Checked the fuses had to take the cover off.Still does not work.Will not turn on and the lights do not turn on...DRubin if you plan to sell your amp let me know.Thanks
