DC - F170U Sanyo Stero can not use radio tuner will not go to any stations how do I correct this

When you push the auto scan button on a radio tuner, the tuner will automatically scan through the available frequencies (also known as a "band") and stop on any station that it finds. The radio will then display the frequency or channel of the station and allow you to listen to the broadcast. The process of auto scanning can vary depending on the specific model of radio tuner that you are using, but in general it is a quick and easy way to find all of the available stations in a particular band. Some radio tuners may also allow you to save the stations that you find during the auto scan process, so that you can easily access them in the future without having to rescan.

Hello Hannes, FM ANT, is the connection of the antenna to receive FM radio stations (Frequency Modulated) Here you can connect a cable of approximately 1 meter, and use it as an antenna, depending on where you are, rural or remote areas. the city, you might need an external antenna, similar to those used for analog TV reception
I sent you a link to download the user manual of your Sanyo

It's not the wiring. It is the radio tuner. It is broken and if it is a mechanical tuner, needs a mechanical part like a small rubber band that connects the knob to the tuner, or if it is electronic, probably needs a new tuner.

Don't you have an automatic tuning system or ATS? By pressing a band switch for a while the ATS starts looking for stations and stores the ones that have a good enough signal. Even if a station broadcasts but the location of the radio is not adequate for a good signal to be received, the station won't register and it will appear to you that the tuner is skipping.

TAKE THE KNOB FO AND SEE IF IT WILL TURN BUY HAND IF SO JUST PUT A BIT OF PAPER ROUND IT AND PUSH THE KNOB BACK ON AND IT SHUOD GO

The system does have a remote (at least it should come with one if purchased new), and you need it to control pretty much everything. Here's what the manual says about the radio tuner (you can find the whole manual here) :

Manual Tuning
1. Connect the FM aerial and the AM loop antenna at the back of the unit. Rotate the AM loop for
better reception.
2. Press TUNER to enter TUNER mode and toggle between FM and AM.
3. When the FM station broadcasts Stereo sound, ST is displayed.
4. Tune a station by pressing repeatedly the TUNER+/- buttons until the desired station is found.
Alternatively, you can press and hold the same buttons down for about one second to activate
the automatic search function. In this mode the player will automatically tune frequencies until
it finds a station.
5. Repeat step 4 to tune to another radio station.

Storing radio stations
The player can store up to 30 radio stations in its memory. You can enter every single radio station
yourself or the player can store all available radio stations automatically in ascending order.
Automatic preset programming
1. Press TUNER to enter the Tuner mode.
2. Press and hold TUNER down for 3 seconds to start automatic preset programming.
Note: A weak signal can affect the "Automatic preset programming" function's efficiency. Adjust the aerial for better
reception and a more efficient search.
3. Radio frequencies will be browsed and radio stations stored automaitcally. When all the available
radio stations are stored or all 30 memory locations are full, the auto preset programming
function will stop.

Manual preset
1. Tune to a radio station (see "Manual tuning" for details).
2. Press MEMORY once to enter flashing Preset Loaction number.
3. While the Preset Location number is still flashing, input your desired preset number (1-30) using
the numeric buttons or press the CH+/- buttons, then press MEMORY to store it.

Retrieving preset stations
1. Press TUNER to enter the Tuner mode.
2. Press CH+/- to search up or down for the preset stations or directly press the numeric buttons.

As you see, you really need that remote. The same is true for disc play. While there are front panel buttons for play/stop, disc skip, and drawer open/close, you don't have any other control without the remote. Without the remote control you'll find this system won't do too much, unfortunately. If you bought this new, check the packing material before you throw it away to make sure the remote's not still somewhere in the box. They often come tucked into slots on the foam inserts.

Also, when you hook the unit to a TV, it's just using the TV as a video display device. The TV has nothing to do with any of the system's other functions.

I hope you have luck locating the remote! Thanks for using Fixya.

To program your radio stations to the memory buttons; Tune to the station that you want to save, then press the memory button (located next to the FM mode button on the lower right side of Tuner) then press the number button that you want associated with that station. You may save up to 24 stations. If you want to save a station in memory 10, tune in station, press the Memory button, then press 1 followed by 0. you must press them within a couple seconds of each other, or the first number pressed will be the memory button that saves. You may save FM stations and then Save AM stations. But you will overwrite any previous station saved to a given number when using that number again. If you save an FM station on a number, then save an AM station on another number, when you press the preset number, the tuner will automatically switch radio bands to accommodate the stations given band. cool.

check your "constant power" (battery power) lead with a meter and make sure it's got 12v dc power with the key "out" of the ignition. If there's no power check the vehicles fuse and the radio fuse. Hope this helps

Hello,

FM ( at least in the USA) only goes 90.1-90.3-90.5 and so on.
This is how stations are separated.
There are no stations on 90.4 or 101.6 and so on

I personaly would replace the entire unit, the capacitor is a Ceramic "DC Blocking/Couplng" capacitor, possibly a 0.001uF cap... I should think if ya take it to any component supplier/radio repair shop or the like they would be able to give ya a replacement?
