The laser is damaged or dirty. Try gently swabbing the lens with rubbing alcohol and drying with canned air. If this fails the laser is damaged and unrepairable.

Have had this JWIN model JK-777 turntable/am-fm/cassette/cd player unit. It won't power on now. Checked the outlet, no problems there. Does this unit have a fuse?
1. It's more likely the problem is a broken power cord or dirty power switch. If you've been in the habit of yanking the cord to unplug the unit instead of pulling directly on the plug, or somebody tripped over the cord, the power cord is probably broken right at the plug.
2. Changing a blown fuse without finding and repairing the fault that blew the fuse will only give you another blown fuse. It's not like the old farmhouse with too many things plugged in on the same fuse... A blown fuse in audio equipment is usually the result of a shorted speaker driver transistor. The transistors come in pairs; if one is bad the other has been overloaded and should be replaced also. That's a job for an electronic technician.
