Re: 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...

Clear pre set tuner stations on CX-NA909

The manual is available for free at On page 12 it explains it.

LG LX-M240 operating instructions: I cannot set the presets

Owner's Manual is PN 3834RH0020U
On pg13
1. Press TUNER/BAND to select AM or FM
(Leftmost rectangular button on left of volume knob)
2. Select station by using TUNING +/-
3. Press PROGRAM/MEMO on the remote
A preset number will appear.
4. Press PRESET +/- (or PRESET ^/v on remote) to
select the preset number you want.
5. Press PROGRAM/MEMO again. The statio is stored.
6. Repeat above for more stations.

Believe you can store up to 30 stations.
Stations on presets 1, 2 and 3 take longer to 'kick in' when listening to the radio
as they are the 'tens' prefix for the preset numbers. 4 - 9 'kick in' immediately.

How do I preset individual radio station frequencies?

To set individual presets: 1. tune to the station you want as a preset 2. hold down the number (ie "1") on the remote until the number blinks on the system 3. repeat for all other stations
press the number on the remote to tune to your preset
this is very similar to setting the presets on my car radio

Clear all the pre-set channels

There's no clear all settings there. You need to manually delete each saved station. Try to unplug the power of the unit for few hours and check if that clears all.
