Mr. Harrison posted a fix on the display on his 2000 Explorer. You
could fix the radio or have him do it for you.
I've seen where a lot of people have had problems with their Mach
radio
system display going blank. I, too, had this problem and after
numerous
attempts to corner either Ford or my dealer to fix the problem at
their
expense (I'm was out of warranty at 54,XXX miles), I gave up and dug
in
to fix the problem myself. My Ford dealer gladly offered to send in
my
radio for repairs at an estimated cost of $455...so much for the
loyalty
I've shown Ford in the last 20 years.
I saw a posting on this newsgroup that helped my out. I'll repost the
message for anyone's benefit who may be having the same problem.
Seems
like the problem spans over Ford Explorers including model years 98,
99,
and 2000. The problem I had was just plain and simple...the radio
display just went blank...everything else worked...though, it is
frustrating not knowing what station is playing or if you depend on
the
time of the display. I consider my Explorer "pampered"...it's always
in
a garage when not in use...not exposed to much extremes in
temperature,
for the most part (though we put a lot of miles on it when it was used
in my former sales position), so I anticipate this is an even more
common problem with others who may leave their Explorer outside. If
you
do not feel comfortable doing this yourself, contact me at the email
listed - , just remove the
"STOP.SPAM.NOW." To supplement my unemployment benefits while I hunt
for permanent employment, I'm looking to repair radios for those who
don't feel comfortable doing it themselves (there will be a cost...I'm
looking at a cost of $89.99 plus shipping...price subject to change if
the demand gets too high...it's less than the $455 that I was quoted)
.
Please, I'm limiting the repairs to those radios that are displaying
the
same problem that I had...a blank (or dim) display...don't send me a
radio that has other problems. If I can't fix it, I won't charge
except
for the shipping. I am an Electrical Engineer, so I have some
background in dealing with these issues...though I haven't made a
career
of the electronics repair side of the business. If Ford doesn't come
to
their senses and repair this problem for the owners, well, I guess I
ought to thank them for a new career.
If you'd like to do it yourself, I'll be happy to guide you through
what
worked for me. If there's enough interest, I'll even do a web site to
show how to remove the radio using a clothes hanger...you'll save
yourself the hassle of trying to find a removal tool...my local
AutoZone
told me to just use a clothes hanger instead of buying the tool.
Here's the directions that helped me...Good Luck:
By opening up the radio you will find a narrow display power board
within the left side of the radio (faceplate toward you). This board
has a metal cover soldered to it, with a toroid (wire wound doughnut)
inside on one side, and a bank of surface mount resistors and
capacitors
on the bottom side. One end of the board (SCR heat sink) is screwed
to
the heat sink at the back of the radio, the board is secured with 2
metal bend-tabs, and it has a white mini connector on the other end
which connects to the faceplate. Remove the board from the radio.
On the bottom of the board look for surface mount components
R1057/C1071/R1058/C1083/R1064. The colder these resistor/capacitor
chipsets get, the brighter the display. I left the car out in the +5
f
degree weather and the display worked until it warmed up a little.
That
is how I was able to track it down to these temperature sensitive
parts. Freeze-it also helped after I narrowed it down to a few
components.
The fix that worked for me was to re-molten the solder for each end of
these surface mount components. Be very careful if you try this, as a
big soldering iron, or a lot of heat will destroy the components and
board. And don't do this with the radio plugged in. If you're not
comfortable doing this take it to a friend who is. So far this fix
has
kept working for a week, I hope it is permanent.
Disclaimers - don't try this without proper training. It may not be
the
same problem that mine had. Don't hold me financially liable to any
damage or expenses you may incur. Fix suggestion is not meant to put
anyone's audio repair business out of business, etc,...
~Thanks to Everett Cotton for the posting these directions (which in
posted from someone else).
Again, I will re-emphasize Everett's disclaimer: I will not accept

Any repair attempts are at your own risk. It may not be the same
