Radio in 94 f150 only plays static. Music plays every now and then but mainly just the static. What is this

the antenna wire probably came unplugged on the back of the stereo

in all modes. new aftermarket or 1970.
the radio will play with radio , cassette, CD, or USB stick and even AUX to the iphone.
so are all dead? if yes,
that means.
the power pin is dead, (lights up does that mean dial lamps or you can see station tuning work, if just back lights that is not radio power
that is the park lights power.
the radio has power wire, main, that must be 12vdc or the radio and amp will be dead.
missing inline fuse. or blown?
most radios have 3 power pins and 1 ground
1: 12vdc power. main
2: 12vdc park lamp circuit, for dial.
3: memory.
4 : ground wire.
take all 4 to work right.
takes 1 and 4 to play music. at say USB port.

Check your antenna. If the mast is not extended, your reception will be limited. try an AM station, usually a local AM station will still come in even with the mast down. Have you tried playing a CD (if equipped) ? If that plays well, you've confirmed lack of reception as the problem. If the mast is extended and you still do not have reception, the antenna plug my have come out of the back of the radio. The requires removing the radio to check.

take out the speaker in question and test it.
a 9v battery is good enough to 'burp' it.
if it makes a scratchy noise when you put power to it then you have a short in the voice coil.
Burping a speaker is just a short power up. Don't hold power to it.
Tap it on and off like a music note measure.

sounds like a grounding problem. need to check if any after market stuff was added first

I would venture a guess that the antenna wire that plugs into the back of the radio is not seated properly. Did the dealer tech just listen to the radio or did he/she actually check the connections on the back of the unit? A faulty antenna connection would explain why it only happens with some stations and not others. Maybe the stations that are not being a problem are transmitting a more powerful signal or are closer in range than the ones that you are having trouble picking up clearly. Just a thought. Hope this helped and best wishes.

your radio is shot, and the cd and tape player still works. You have to buy a new radio if you want to listen to a radio.

tepfy

remove coins from the cigarette lighter or unplug it. Never put a bigger fuse in than what it calls for tha is a BIG mistake.

you need to install a filter on the power leads of the radio and the amp.  The filter in your electrical system have gone bad and your alternator is generating noise.  Have you recently done anything on the cars electrical system such as spark plugs or wires? 

I jsut did this with my 94 F150. There are two little gizmos that you can buy at an suto parts store that are the removal tools for radios, They are U shaped and you plug them in to the radio face until they lock and the radio come right out.


Hope this helps Good Luck Loringh
