Radio Display problems, flickering, blank, etc
Ford Owners,
I recently posted this in another forum on this site then moved it here to spread the word.
I own a 99 F150 and the radio display was flickering then stopped working all together. The radio I have is a tape deck, radio, external CD changer type. I put up with the problem for a few months then got fed up and decided to tackle the problem. After spending some time on it I discovered the problem to be faulty soldering on two resistors for the display. I was lucky and the resistors were not blown (remove and test or you could test circuit resistance). Instead they just needed to be resoldered. Before I found and repaired the problem I searched the internet only to find many sites offering to charge me for a solution. No charge here!
To fix the problem you will have to remove the Radio and disassemble the face plate. From there you should find two resistors for the display. In my particular radio they were labeled as R464 and R465 and next to the tape slot cut out. The solder joints were discolored and upon closer inspection (magnifying glass) I found further faults with the soldering. I then gently tugged on the resistor and it came right off the PCB (printed circuit board). I hope this helps!
Here are some pics describing the process with more detail
Remove the radio
Remove the faceplate from the radio
Repair any soldering that appears to be faulty or the component is loose. Use a magnifying glass to visually check the joints for cracks or lack of solder. I found that Ford, or whoever built the radio, could have used more solder to stabalize the joints a little better. As mentioned above my problem was that resistors R465 and R465 were loose on the board. These two resistors control the current for the display. Once I resoldered them the radio worked!
Cheers!
