Instrument Cluster LCD light issue

Recommended Posts

Odd happening with this LCD display lights. Long story short, had the original (3) 1.5v beige bulbs replaced by leds in Blue, after 8 yrs decided to go back to beige bulbs and now they don't illuminate. I checked B1 and E1 fuses are ok. The Car has all LED lights except all instrument cluster and A/C panel. What else to consider?  1999 Carrera 2 STD

I was using it with LEDS for 8 yrs. No single issue. I just got bored of the blue light then went to original, now doesn't work. I start thinking in a short inside the instrument cluster. 😞

The LCD lights that backlight the odometer and temperature do not work on my 1999 Porsche Boxster.  I changed to new light bulbs and they still don't work.  Before dismantling the cluster and analyzing the circuit board I want to test to see if the lights are getting power.  Does anyone know which harness and pins provide power to these 2 lights?
