Instrument Cluster LCD light issue

[jose]

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

Any one?

Check fuse B10

Thanks for share. B10 fuse is Ok. I suspect the instrument cluster board problem. Still no idea. Other instrument cluster lights working fine.

A mix of LED and traditional bulbs never seems to work well. Some LEDs require a resistor inline to work at all.

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. 😞

Put the LED bulbs back in and test to see if it works like it has for 8 years.  If it does, then it is probably (as said) the mix of standard and LED bulbs that makes it not work.

Did all ready. I sent it for repair

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?

I sent my cluster to EZELECTRONICS they diagnosed an internal problem on the circuit board.
