Opened the inside. Next to fuse, it says 8A 125VPower cable says it is 7A 125Vdevice doesn't not work. Could this be the problem?Not sure if the power cable is the original.
Did you check to see if the fuse was blown? Non- operation can be caused by fuse deterioration over time, in relatively heavy current situations. However usually, a blown fuse is indicative of more serious problems, which will not be rectified by replacing a blown fuse. A replacement would just blow again. The power cord/ fuse markings are irrelevant, they're fine. They are there to ensure any replacements are fit for the purpose they were intended for.
No this is not the problem. Your equipment probably only draws a few amps, well below the rating on both the power cord and the fuse. Power cord and fuse rating do not have to match.
