Question about Sony CFD-E75 Cassette/CD Boombox
When I attempt to play cd or radio, it starts then fades away and the lcd display goes blank. If I hold the end of the ac power cord at an angle where it enters the unit, sometimes it will play. I know that the cord is good (I used one from another Sony unit), so I'm guessing it must be the ac inlet inside of the unit. Would this be correct and if so, where could I find a replacement. I've opened the unit and looked at the inlet plug, but did not observe anything. Thanks!
Remove the power plug and reopen the unit. Usually the socket will be soldered directly to a Printed Circuit Board. Look in the underside (where the solder joints are and you'll see the joints associated with the power socket. One of these is either a bad connection or the solder pad has lifted and broken the track on the PC board. If it's the solder pads give them a workout with a soldering iron if it still plays up scrape the protective lacquer of the PCboard Tracks and resolder them to the socket's solder joints. This should solve your problem. The best way to spot a bad connection is to reinsert your plug (making sure the other end isn't plugged into the wall socket) and lever the plug up, down, left and right. If there's anything faulty you'll see it. The solder joints will move very slightly and if the track is fractured you should spot that too. One other tip is that there is a switch built into the socket which will disable the battery power when you plug the unit into power. I have seen a few of these switches go bad but the chance of that is extremely small. I'd put my money on the socket's solder joints. BMW

Fuse blown in primary of xformer, you cannot replace it but get creative, measure across the 4 pins on xformer, fuse is across last 2.

That is an electronic problem. Probably a just-about-to-break cable in the motor of the CD drive, that sometimes causes a short and turns off the unit, or sometimes makes it to comport erratically and produce the buzzy sound. If you have electronics knowledge, then you may open and check the wiring harnesses. If don't, take it to your local electronics repair.

Testimonial: "Thanks! In terms of price though? Would it cost as much to get it repaired as the CD Player itself? Or is it a reasonable price?"
Tv repairs shops carry a selection of power supply cords, also check out Radio Shack Stores.
