Re: 164 LCD display

[Jarmanhome@domain.elided]

Regarding your question on repairing the faded-out digits on the LCD display 
for the heat/vent/AC controls, there have been volumes discussed on this 
issue, but few firm solutions short of a new unit ($$$$$$).

The problem (and understand I've never repaired a display myself) is 
generally cold solder joints and cracks in the ribbon cable termination, 
where it  is bonded to the circuit board at the back of the unit.  A handful 
of owners have apparently resoldered these connections and restored some 
clarity to the display.  But the points are so small, it is very diificult to 
do this without botching the entire conector.   Much discussion can be found 
in the AD archives, and at the old 164 Forum at 
www.digest.net/alfa/FAQ/164/notes0.htm

I suggest you remove the unit, and allow a competent tech at an industrial 
electronics shop to repair the cable for you.   They deal in this type of 
hardware all the time, and have the proper equipment to diagnose and possibly 
repair the connection point.   Good luck, and if you find a breakthrough 
solution at reasonable cost, many late model 164 owners would like to hear 
about it!
