Tunner circuit board


5140019-42 Tuning knob assy is the most common - it can also be the PCB but if the radio works but you can't change the station I would replace the tuning knob assy

Radio worked fine......then I was trying to find another channel by turning the tuner knob and all of a sudden it just locked and when I turn the tuner knob it won't change stations. Nothing works but the...


This may help: If you take off the front of the radio (don't forget 2 screws in back!) you will notice a set of black and red wires running from the 2 AA backup batteries to the digital display circuit board. The wires plug into the board with a little white plug. If you unplug this the display will fade to nothing. If you plug it back in it will display an unset digital clock format. This seems to reset the radio, after which it should work.

1. Select the Radio Station you want to save.

The radio stations will not stay set when I turn radio off/on. Keeps going back to 87.5 on all memory buttons.


Hi. There is likely an internal battery within the device that has run flat over time. Changing this should cure the problem.

No functions working , tuning nob turns but the station dos not change,stuck on fm no sound


Many of these radios have memory backup batteries and when they become weak or dead the microprocessor becomes wacky.

The tuner knob will not tune to specific stations and is eratic when turned not being able to pick a station needed.


If you use your radio at work it could be exposed to dirt and dust and more! Could just need a good cleaning, drywall dust is terrible on electronics!

Tuner


This sounds major.....

The signal detection used in both radios and TV sets is via special voltage sensitive diodes which alter capacity as the voltage across the diode changes.
You actually change the voltage across the diodes as you move the tuning dial.

In your case the diode only sees one voltage and is locked to a certain station, because you are not altering the capacity to re-tune to another station...

So it appears that you have lost the ability to alter the DC voltage across the diode...

The design of the tuning knob may be where this fault lies, where the physical action of turning the tuning knob does not transfer the mechanical action to the item that changes the DC voltage to the diode....maybe you have systen that uses a long cord would around pulleys that gives you nice control over the tuning maybe its just a broken tuning cord...
Maybe the tuning is done by just a simple variable resistor I'm not familiar with this system but I have given you the bascics to start on...Unplug the cord from the AC wall socket then remove the top of the cabinet and have a look to see what moves when you turn the tuning knob it will soon become apparent if there is nothing moving when you turn the knob and thus lead you on to the problem....
Maybe the knob is just loose on its drive shaft...
