Another Radio Display Fix
OK, so you can add my name to the list of X owners with no display on my HU.
I have a 98' Sport with the Mach sound system, and my display went out at around 50K miles(this was about 18 months back). I lived with the problem for about 6 months when I was lucky enough to stumble upon this board and find this thread... So, after popping out my system and cleaning the display driver board, this fixed my display... For a while...
About 2 months ago, the display died again.. I decided to try to find a more "permanent" fix. After calling Ford and Visteon I was able to learn that the Mach system's Head Unit is indeed manufactured by Pioneer. I found a telephone number for Pioneer's parts center off their website, and was able to order a replacement board. I received the board about 3 days later, installed it in my system, and it has been working fine for about a week now...
If you'd like to order the part from Pioneer, their parts center # is (800)421-1404. You will need to give them the Pioneer model number off your HU for them to cross reference the part. This model number is located directly underneath the Ford Part number on the label underneath the unit. For example, the Ford part number on my radio is F87F-18C868-BD and the Pioneer model number is FH 2116 ZF, so look for something in that format. The part(s) that you will receive is a "kit", which includes 3 circuit boards. This included not only the display driver board, but also 2 other small boards, one of which contains the rear connectors for the radio and another small board located close to this(they would not sell me the display driver board separately). The part number for this kit is HWM5469 (at least for my radio model). I only replaced the display driver board, which was VERY easy to do, and this fixed my display problem. To replace the other 2 boards, you would need to completely disassemble the radio and make at least 20 - 30 solder connections. I didn't suspect these boards to actually be bad in my radio, so I didn't think replacing these would be of any benefit (and it could be very risky if you're not adept with a solder iron). With shipping and handling these parts cost me about $95, much less than my Ford dealership and most repair shops wanted to fix it. If this permanently fixes the problem and prevents me from having to dismantle the radio every 6 - 12 months, it should be worth it!
By the way, two differences I noticed on the replacement board:
1) The 2 watt resistors on the top of the board located under the shield are mounted about a half inch above the circuit board. I’m guessing Pioneer realized the design flaw of placing components that generate that much heat directly next to other sensitive components.
2) The quality of the workmanship on the replacement board is significantly better than the original board. On the original, you’ll notice very poorly soldered connections on the bottom of the board, and A LOT of excess flux which was never cleaned off the board. I consider this as a contributing factor to the original failure.
With that said, I STRONGLY URGE anyone who has had this display problem to contact Ford’s Customer Relationship Center at 1-800-392-3673 and report it. I spoke to them on several occasions trying to get this issue resolved, and they denied any knowledge of the problem. They did state however that if enough owners complained about the problem that they may consider implementing some sort of program to cover it (e.g. extended warranty on the radio). It really disturbs me that I paid approx 30K for this truck back in 98’, an extra 1K of this for the sound system, only to have it die 3 years later and have Ford completely deny that there is a problem. I spoke to two different Ford dealerships, and several radio repair shops, and THEY ALL stated that they see this problem A LOT. I would think that a company with the motto “Quality is Job 1”, would be interested in resolving a “quality control” problem that effected a large number of customers.
Anyway, sorry about the rant at the end, I certainly hope this info helps somebody out there!
