Hi - I found your forum looking for some advice on the possibility of repairing my Subaru Legacy dash clock & fuel info display.
The problem is that sometimes the whole display turns off as though it is getting no power. Over the last week or 2 the display has spent gradually more time off than on. When it comes back on everything is displayed correctly, when off absolutely nothing is lit at all. Makes me think power side related rather than anything more complex.
The bottom of the clock gets hot when running - I have just connected it lose in the dashboard to try to find out if there are any consistencies to when it is off or on.
Looking for any dry solder joints I took the unit apart to see if anything obvious - looks like it may be heat related from the centre resistor in the bottom of the clock? There is a brownish haze that has spread equidistant from the centre resistor on the rear of the PCB and also the white band at the bottom of the front of the PCB is only brownish in the region of the centre resistor.
Pictures below...
Any ideas?
My first thought is to swap out that resistor - would a failing resistor be generating excess heat? and why would it work sometimes and other times not work???
Any advice appreciated
Thanks
Mick
