amc49 If they put it together you can take it apart, doing so though often requires being creative as to coming back up with alternative ways of fixing fasteners that were intended to be broken to disassemble things. Ever took apart a Playstation 3?, Brother, they do not intend for kids to be doing that...................

sico9512 Well done I fixed my daughters car cluster is now working fine thanks to you

sailor AFAIK, Ford only sells the "assembly" - so you'd have to find an electronics supply source for that specific component...

Whoever built it got the part SOMEWHERE, but guessing where? THAT'S the rub....

Engineering parts supply catalog.....

Finding a source that'll sell you just ONE....

used cluster is probably a bit easier when the time comes.....

luck!

(and as whynot mentioned, more questions REALLY need a new thread to get the best answers....)

whynotthinkwhynot Please start your own thread. The last post before you was 9-27-2010. You'll get better help doing that than bringing up an old thread.

The LCD Read Out in the Instrument Cluster

I am just curious if the LCD in the instrument cluster can be replaced w/o having to buy a whole instrument cluster? So far the odometer is reading fine, but the trip reset reads of the numbers as though the crystals are getting bad in the LCD?

Thanks for any help!!!

sailor Posted via FF Mobile "wave" soldering works OK, unless you have a joint that got contaminated somehow, so no solder sticks.. Had a Marine radio that acted up, on opening it found one joint with no solder, mechanical contact was all that let it work at all... freshly soldered & fixed permanently... Vibration is hell on solder joints in cars, more than one component I`ve fixed just needed resoldering... Unfortunately getting to the board is less & lesss possible on many parts...

mikeeshaq OK
Electronic Technician since 1969.
Be sure to use a GROUNDED soldering iron! Otherwise the stray AC leakage might do in the sensitive circuits.
Also because of Europe's phasing out of using any lead in any products[Rohs], the solder is probably tin. Tin solder has a nasty habit of growing whiskers that will short out adjacent pads etc.
We in the USA still can use leaded solder without any legal hassles unless it goes to Europe.
That junk that you saw on the board... sounds as if the flux was not removed entirely.
Be aware that in the winter time in the North the air is extremely dry and static electricity will occur and can damage sensitive electronics either immediately OR[!] later on.
The amount of static that can destroy electronics can be below human perception. So just because one is not going snap crackle pop on carpet does not mean that one is OK.
I should mention... use of lead solder on plumbing is cause for a great sanction from the government.

niggly51 I am afraid I'm going to have to take issue with your comments whynotthinkwhynot. Having worked in the electronics industry for the past 30+ years, mostly in circuit board design- there is not a commercial process that I am aware of, called 'cold soldering'. Most commercial components are soldered by 'wave soldering', where the placed board is passed through a vat of molten solder, making the joints. Surface mount components can also be done this way, but they are generally 'reflowed', where solder paste is applied to the board- the component placed- then infra red heat is used to melt the solder. The vast majority of problems with circuitry these days comes from the use of lead-free solders where the high levels of tin in the solder have led to poor solder joints and the formation of 'tin whiskers' which cause short circuits.

whynotthinkwhynot Ford likely uses what's called a "cold" solder with the robots. I seriously doubt that even China uses manual solderers these days. Cold solder is not cold, but momentary electrical arc liquifies the solder as it is applied. It cools nearly instantly. Quick joint, but not a reliable joint. I have yet to remove my 05's instrument cluster, but I'm curious to see if Ford still uses the old printed circuit boards with the really wide circuitry like on their older vehicles. Those are top notch IMO as compared to GM's crapola.
