Appears to be "locked up"; key image on top of display but lowering the LOCK switch on the side of the radio doesn't help. Using ac adapter for power - display light works so power seems OK.. House power off for a while, then on so may have been power surge ? Where can I get a schematic ?

Yes you can use any 6 volt DC for your radio but the most IMPORTANT thing to remember is to connect the terminals in the correct direcction. First of all you can solder a red wire from the positve terminal of the battery and a black wire from the negative terminal of the battery. This must be connected to the source of your 6 volt battery.You can buy a good DC jack socket female to be fitted into the vacant spot of your radio and use a male jack to supply the DC. Only be carefully to see the polarity. To avoid any reversing of polarity use can even connect a diode in the forwarrd bias towards the positve terminal. This will prevent any wrong connection of polarity to damage your set. Helpful? Good day
Your set is not switching on and you will need to check on the power switch on circuits. Have to check if the battery voltage is going to the porcessor , please check around this stage for any signs of dry/bad soldering, use a low wattage iron to touch on , but be very careful , use a multimeter to probe the voltage in the circuit hoping to find a damaged component.check the crystal freq input. test the signal track and move on. if not your processor could be defective. I hope i could help. Good day
Hi. I have a different Jwin model radio to yours, but they might have this in common: is there a 'hold' button on yours?
If so, this is used to 'lock' all the buttons so that you don't switch it on/ change stations etc accidentally.
Look for a 'key' symbol on your display, and press AND HOLD the 'hold' key until the symbol disappears.
Pressing the 'hold' button briefly will make the symbol re-appear, and lock the keys again.
I think the E means a dead battery. You could have intermittent solder connection on your DC input jack. This could effect battery operation as well. Check for bad connections and resolder also look for broken traces at these connections. Good luck.
