Sounds like you have a short in the unit. You will have to take it apart and check the power supply for bad semis. My best guess is that your problem lies in the power supply. Let me know how this works out.

My jenesen uv8020 wont power up i hit the rest buton and the blue buton lights turn on but turn right back off i replaced my front broken screen it powered up it worked for a 7 months when i would tu


I need more info. Did you check the ground wire to make sure you have a good ground? Some installers try to rely on the antenna for a ground when hooking it up due to laziness and it will eventually burn the stereo out from low voltage, or, you could have amps that are killing the battery enough to drop the voltage down and it's killing the stereo. I have also seen ground loops kill stereos, but, I need a bit clearer info as to exactly whats happening to answer the question.

Why won't my Delco stereo will not power on?


Hi Carol

Their are two possible thing that causes your stereo fail to be working.
1. Power supply terminal is not properly attached.
2. Busted electronic component inside the stereo.
Some stereo, when their is busted component inside, it wont turn on. So you better have it check to authorize technician or by your self.

Programming the cn101a timer


CN101A programmable weekly digital timer
Buttons
C = Master Clear, erases all program settings and current day/time.
C/R = Control/Reset, used to access programming mode and to clear individual programs.
You must press and hold this button for approximately 4 seconds to enter programming mode if there is a lower case "a" to the left of the time display. The system will revert back to active mode (with the lower case "a" to the left of the time display) after 30 seconds with no buttons pressed.
If this button is momentarily pressed while viewing a program, that program will be erased, but ONLY the On or Off program that is being viewed will be reset. The corresponding On or Off program in that cycle will NOT be reset.
Clock = In programming mode, this button is held depressed at the same time as one of the D+, H+, or M+ buttons to set the current day and time. When editing the programs, this button is used to exit when done.
P = Program select, each press will advance through the On and Off programs (presets). There are 16 On/Off cycles available (1 On, 1 Off, 2 On, 2 Off, ... 16 On, 16 Off).
D+ = Used to change the day when setting the time, or day(s) when changing a program.
When changing a program,
the following 15 different day combinations are available using the "D+" button.
MO; TU; WE; TH; FR; SA; SU; MO/WE/FR; TU/TH/SA; SA/SU; MO/TU/WE; TH/FR/SA; MO/TU/WE/TH/FR; MO/TU/WE/TH/FR/SA; MO/TU/WE/TH/FR/SA/SU.
H+ = used to change the hours when setting the time or a program.
M+ = used to change the minutes when setting the time or a program.
Manual = This button will cycle the output relay from AUTO to Manual OFF, back to AUTO, then to Manual ON, and finally back to AUTO. Programming mode must first be accessed using the C/R button to use the Manual feature. The manual On or Off settings will override all programs until switched back to AUTO.
There is a Lithium Ion battery which is intended to keep the clock going for up to 3 years during loss of external power, but the output relay will not work on internal battery power.

My stereo is not coming on.. the time will illuminate when i press the display button and the lights behind the buttons will come on but will not turn on.. the cd will eject as well but thats it..


Sounds like the fuse for the switched power has blown. The stereo has two power inputs -- one unswitched, called "memory" because it lets the stereo remember your presets, and one switched, just called "power"

It should let you see the time, eject a CD, etc all when the car is turned off. Since the fuse for the main power line is blown, the stereo thinks the car is turned off all the time.
