LCD's are quite complex, made of microscopic layers of chemicals and specially formulated, treated glass and polymer:



In the middle is the liquid crystal, around 10 micrometers thick. On larger displays, microscopic glass fibers are inserted to keep the thickness constant.

The construction of the displays must be done in a clean room, under very strict tolerances, with exacting amounts of chemicals, masks and coatings applied in exactly the way that is required to make the type of display being manufactured. The LCDs are sealed during manufacture to prevent moisture, air or external contaminants from getting into the layers and causing the display to delaminate and fail.

This is exactly what is happening to the LCDs in the GL1500. There's no way for anyone to physically disassemble the display layers and repair it - failed LCD panels simply aren't repairable. The only "fix" is replacement.

Now a question. What exactly is wrong with yours? Creeping black crud or just not functioning. The creeping crud is fatal. LCD not functioning caused by external problem could possibly be repaired.

Right. A failed GL1500 LCD looks like this:



And for whatever reason, every picture I've seen of a failed GL1500 LCD shows the black circle emerging from the right side of the display, halfway down.




I suspect there must be a design defect of some kind that is the cause of this. I've also read several reports where people said they left their bikes out in the sun, and came outside to find their displays failed like this. This makes me suspect that the display may be put under stress when subjected to high heat, perhaps intensified by the magnifying effect of the windshield, which can focus the sunlight down on the dash when the bike is parked with the sun behind it.

However...if the LCD is just not working at all, and there is no evidence of the "creeping black death" then the problem is very likely other than the glass panel itself.

What company made these. They seem to have same problem on most of the failures. we should have grounds for a class action lawsuit.

You can still get them new, Cyclemax has them for $440. Part number is 37130-MAM-T01, https://www.onlinemicrofiche.com/cyclem ... ewcart.asp

Looking on eBay, I see one used for sale, they want $400 for it. Thanks, for that I'll buy a new one. :)

I am in eastern Ontario. From what I have seen online a replacement is going to cost a chunk, especially factoring in duty/taxes/exchange, etc. Ouch..I have not seen any available in Canada. I had a look at the sites suggested above, and a bunch of other, nada... I have put up with this for a couple of years...it does not affect drivability... I will continue the search...many thanks for the Cyclemax reference. I have had success with getting parts from them in the past. No reason this time should be any different.

My display wont work when it is damp, It doesn't have the half moon issue and the clock can run crazy while it's damp. Starts working after a few minutes of driving. I am assuming the heat from the engine dries the circuit board and it works as intended. It's a bit of a PIA as the radio and the on board compressor wont work until the display begins to function again. Is there a repair for this kind of failure??

There is an article here about fixing the clock issue speculating that it is due to moisture. It walks through the process of sealing the circuit board, which would probably fix your issue as well.

I have the same issue. My means of dealing with it is, well, a little extreme by some people's standards, but it works 100% of the time. I have a small heater with a fan, and when the bike is parked during damp weather (pretty much all winter, here in the Pacific Northwest), I leave it on top of a bucket, blowing up into the area behind the front forks/gauges area. It only runs a total of a few minutes a day (turns on every hour or two, runs for 10-20 seconds, then shuts off, and is adjusted to only produce luke warm air at most) so it costs very little to run.

The result is that my LCD always works, and the compressor, radio, etc. always function as normal. My thinking is that the symptom is the harbinger of a possible future total failure of the LCD, if it's left in damp-and-not-functioning status for long, and forestalling or preventing this failure is worth the few pennies in power it costs to keep it dry & happy.

Just my $.02 worth...

That sounds like something I would do if I were having that problem.

How did you control by time ? Specifically. What device will do that ?

Probably just luck. It's an old heater we used to use on our boat to do frost-watch duty in the cabin. It has temperature settings from 1 through 10 (under 1 is frost watch only, and I set it at about 1.5) and has 3 heat element settings (low filament, high filament, and both filaments - I use the low one only). It just seems to work well, coming on only occasionally, and I doubt it costs me $5 to run it for the winter.

I just went out and looked at it - it's a DeLonghi TU-02. I'm sure they don't make that model anymore, but I see a used one sold on Ebay for $8 a while back. They do make a similar newer model called the HTF3033, although it has twice the power of my old one. You might find one of the old ones like mine in a secondhand store...that's where I got mine. Think I paid $4 for it!

That would be fine when at home, a little inconvenient when travailing on the road.

True enough - although when I'm using the bike daily, the problem doesn't seem to occur. It only happens when it's parked for days or weeks at a time.

I noticed the instructions only refer to the large board on the back most part of the display. The author states that he did nothing with the smaller board as no one had suggested to treat that board. I was wondering if anyone has treated the smaller board the same as the big one?

From what I've read, no repairs available seem to be a long-term cure for this issue, and it seems the '97 SE model is the most prone to it (guess what model I have?). I suspect it's likely that the cleaning, sealing etc. of the LCD would be ineffective in the long run. Obviously, replacing the LCD is the actual cure, but as they're getting hard to find & verrrry expensive, my "heater" solution looks better every day!

Yes, just my luck too, I have a 97 SE. I love her dearly. Hopefully the cleaning and sealing will do the trick.

I sincerely hope it works! Whichever way it goes, PLEASE, let us know! It would be of great benefit by those of us suffering from the dreaded "LCD edge-of-wetness" affliction, regardless of outcome.

When I first started looking for my Goldwing about 7 years ago I noticed quite a lot had a leaking LCD display.To buy one in the UK it would have to be imported from the States... probably?.....so on top of the cost of a new/used one there would be heavy postage charges plus 20% taxes on top when it arrived,unless purchased thro' the Global Shipping Programme.I eventually found a very nice low mileage (40,000 Klms/24,500 miles),Anniversary model,1500 Interstate which does NOT have an LCD display,and came originally from British Columbia/Canada.

would it do any good to seal the edges with sealer to prevent it leaking before it starts
