I have had this hifi for around 3 years, went to turn it on the other day and the display isn't working. I checked the manual and noticed that the display has three cyclinic modes display, time and off so i checked all three modes and none show anything on the display. I then reset the unit as per the manual by unplugging, replugging and holding stop, clear and display.
I am an electrical engineering student so i should be ok to fix the unit i was hoping for some insight into the problem and if anyone else has had a similar issue.
Thanks in advance
This Problem needs an expert Technician:
Your problem is due to a missing Voltage around -30 volts that supplies the screen Processor. It could be an open low value resistor or defective switching transistor.

I have kenwood rxd m1md . it was on and it got extra voltage. now its not working.
the current condition is now when I turn it on, the display turned on for 2/3 seconds and then it shuts down. few green -------------- dots blinks starts, some times "auto power control on " also displays.
Please tell me what happend to this unit? which IC or part have to change?
The fact that it turns down again means it's probably fixable.
Open it up (switch it off first), and fetch a soldering iron. Look around for wires that go from the volume control and see if any are loose connections/broken wires etc etc. Solder these again, and it should work.
If you don't fancy this, take it to a hifi shop and they'll fix it for you (there'll probably be a fee involved)
Optical lens requires cleaning. Please put cd cleaner in tray and check if it cleans dirt on lens. Still same problem, then unplug unit from AC outlet, take off top cover of hifi system and clean lens with good quality cotton bud. hope this will resolve problem.
Hello, HiFi system actually turned Off when you press power button and display of hello, heavy, vocal etc is demo mode of this system and it activates when unit goes to power off. You can change its settings like not to show demo mode etc and this procedure is described in owner's manual. Thank you.
Failure of this laser is quite common giving a no disc message in the HiFi's display. A defective laser can also be responsible for an intermittent no disc message and general playability problems with CD discs. Part number Optima 7 / 7B Laser Assembly
Please switch off the system from the wall socket. Remove the speaker wires from the rear side of the system. power on the system if it works ,the speakers or the wires are defective.

Was the fuse Blown?? check with an ohm meteracross the two prongs that you plug into the wall of course you gotta unplug it for this. It should read around 4 to 10 ohms depending on the type of power transformer is in the unit.. If it reads open then theres a fuse open or a bad power transformer. If its not open check the power supply for the proper voltage from the diagram.
