LDC dims or goes blank in cold weather

Postby KenWiggers » Fri Nov 15, 2013 10:06 pm



I had a 2006 (no Nav) and with colder weather (50 deg. minus) the LCD starts to fade out. When it is partially lit the display functions all show but as the temp drops all the reading disappear. By the upper 30s it's just the backlit screen - no info. On warmer days it's just fine. Any ideas?

Did you by chance replace the back lights with LED's..??
A liquid display does not work well in the very cold.The lamps are used to keep it warm just like your watch on your arm.LED's don't produce very much heat.

Interesting... I bought this bike with 26k+ and started riding it last Mar. Didn't have any noticeable dimming problems last spring. So whether the previous owner would have installed LEDs is an unknown. Will have to pull it apart to see.
Thanks for the comment. I'll see if there are other comments/opinions. If not I'll pull it and have a look.

I rarly see 30 degrees down here but I believe the Admin may have some input about this.
I do know that there is a operating temp range that lcd's will operate in.I don't think below freezing is one of them.At least not for this vintage of display.

Remember that the "L" in LCD stands for Liquid. When LCD displays get really cold, the liquid suspending the crystals gets very thick, so changing from on to off or off to on takes longer. Kind of like trying to stir honey right out of the microwave compared to honey sitting outside on a cold day - which is easier to move around?

At some temperature I'm sure LCDs will stop working altogether, although I don't know what that temperature is.

I ride my 02 well into the teens and single digits and haven't had my displays dim. I'd check the connections for gummed up and solidified contact grease. Many types of lube used in switches, lamp bases and connectors are negatively impacted by the cold and heat variations. I've lost tail lights vehicles and last year had issues with what ever lube was used in my bike's switches. Spraying and cleaning them out fixed it. You also mentioned having installed LEDs, so I'd recheck all the potential connections that may have been left loose or that could have been damaged in the process.
