GL1500 LCD Issue

Postby Mh434 » Fri Oct 24, 2014 2:08 am



Well, like so many others, I now have a completely blank LCD screen on my '97 GL1500SE. I haven't run the bike in a couple of weeks, as the insurance expired & the 9 months of rain we get has started here. The bike's in a closed garage, but the humidity is extremely high & temperatures are down to the 40 F range.

I started the bike anyway, & ran it up to temperature, then left it in frustration. I did note that a couple of idiot lights weren't functioning either, but everything else on the bike was working normally.

After reading about '96-'98 LCD panels going out when they're damp, I decided to go back out and take another look. Bike was nice & warm and, when I turned the key, everything was back to normal. Frustrating, as fixing this well-known problem is a LOT of work.

Anyway, while I was inside on the computer (before getting the panel working again), I started researching replacement panels. OEM ones appear to be available new, for not much more than used Ebay-sourced ones.

Strangely, for the '97SE, I found one part on the fiche, with three different part numbers possible - 37130-MAM-A80, 37130-MAM-A81, and 37130-MT8-771. The first two are in stock ($378.03 each), but the last one is a) more expensive, at $413.67, and b) no longer available at some online OEM parts places.

What I can't figure out is...what's the difference among the three? Color of the fuel & temp gauge faces, maybe? For the life of me, I have no idea which of the three my bike would require, and all three are quoted for the '97SE.

Anybody know what's going on there?

You may have to go to the stealership to get that answer......or just live with it! My 96 has the same issue and I did the remove, clean and reseal with some improvement..but on really humid days it still blanks out. Any more I just ignore it and wait for the unit to clear itself.....

Good luck on getting the correct answer!

That's interesting, because when I did a lookup for the 1997, the only one I show as applicable is 37130-MT8-771, and it is shown as no longer available.

Yeah, I thought it strange as well. I found the three part numbers on the '97 fiche at Ronayers.com. The LCD panel is shown as part 15 on the diagram, with 3 different possible part number options. Interestingly, the first two part numbers were found to be available at other OEM parts dealers, referring to "LCD Panel". No reference to which one is right, though.

I'm wondering if the cheaper part numbers are for the panel itself, without the fuel & temp gauges...

So what's the difference between all these LCD panels? I have no idea. I kind of suspect that they might be interchangeable, however.

One difference would be the readout for air, ours would be in psi others kpa or whatever and maybe the AM-FM radio band frequency step or spacing for different Countries.
This is what I do

Well, my LCD screen has blanked out again already. Typical Pacific Northwest rain - measured in buckets, rather than inches. Washouts everywhere, eavestroughs overflowing, garage roof leaking in several places, no possibility of drying the bike out & keeping the LCD screen working. Frustrating & worrisome...

Well, I decided to try something - I have an old, small, beater space heater with a fan in it, so (once I got the LCD working again by running the bike for 10-15 minutes, and the engine heat dried it out/warmed it up) I put it on a box and placed it beside the front wheel, blowing up toward the underside of the instruments. Just a trickle of warm air, but it's reasonably dry. So far, after two days of heavy rain, the LCD's still working.

The heater is set to its lowest setting above "frost watch", and the fan is barely turning. But, it seems to be working. I just don't like the idea of the LCD being damp for a long period of time, in case it gets to where it won't dry out & function again!

**I should add that the clock is back to keeping perfect time again...seems that its timekeeping is directly linked to how warm/dry the LCD panel is?!**

Mh ... I would be a bit concerned about all the costs and possible fire concerns a space heater might cause you down the road ... I have had very good luck using a 50 watt light bulb in a small lamp shining onto a surface I wanted heating up with very good luck ... For what ever it's worth. ;)

Yup, as long as you can still find an incandescent light bulb, being that our esteemed government has decided that we shouldn't have them anymore. :evil:

Using a 60 watt bulb in a purpose-built tent underneath a small airplane engine is a common way to pre-heat it on winter days.

I hadn't thought about the light bulb - I used to do that as an ersatz block heater.

As WA points out, they're not easy to find, now! I'll check the dollar stores - that's about the only place I've seen them recently!

In the interim, it looks like the little heater's only coming on for a few minutes a day. I used this heater to keep the cabin in my boat dry every winter for about 9 years. Pretty good value!

I have a few of those incandescent globes that I could let you have, but they are 240 volts. They have stopped selling them here as well (in Oz), but you can still purchase "specialty globes" that are incandescent but have different shapes (eg like candles or oven globes) that will give you enough heat for your job.

hello
On other forums, I read that this is recurring. One solution is to spray the solder side of the display printed circuit (tropicalize the PCB)
To do this, use the Clear acrylic lacquer (or varnish printed circuit board)
Of course, you must remove the dashboard to access the display printed circuit.
kind regards

In french:
Bonjour
Sur d'autres forum, j'ai lu que ce phénomène est récurant. Une solution consiste à vaporiser le coté soudure du circuit imprimé de l'afficheur (tropicaliser le circuit imprimé)
Pour cela, utiliser du vernis acrylique incolore (ou vernis à circuit imprimé)
Bien sûr, il faut démonter le tableau de bord afin d'accéder au circuit imprimé de l'afficheur.
Cordialement
