LCD display failing

Recently I left my GL1500 in the driveway on a hot day with a cover over it (normally it's garage kept). When I removed the cover later, I found a semicircular area of the LCD display was black. When I turned on the key, the remaining portion of the display worked normally, but the right most digits were obscured by the black semicircle.
About a week later, I took the bike to work and left it in the parking lot. That evening the clock digits no longer worked. They were not blacked out like the semi-circle. They just were not printed. Now all I can see on it is some of the radio station. Every thing else on the bike seems to work fine.

Does anyone know how hard/costly it is to replace the display?

If you go to a stealer it will be alot of $$$$.

I have seen them used on EBay. I think there is one there now. As far as how hard to replace I can't help there as I have not had to do it (yet).

e-bay normally gets upwards of 300 bucks, honda online is 5 bills and hdlparts online is over 4 bills. Mine is doing the same thing, but I can live with it for a while.

There is one on e-bay now, bids were up to 199.00, and another with the whole dash for the same, but it has 5 days left.

Keep your eyes open on eBay . . . . . . I've seen them go through a lot cheaper than that.

Riders on this site have talked a lot about sierra electronics. Maybe they could fix your problem. Look up under forum search for more info.

Where are you getting those "5 bills" and "4 bills" from??

I've had 2 go down like that. The two halves are delaminating allowing the crystals to run between the glass sandwich. It's knackered. £709 from Honda in the UK! I bought one off ebay '95 model for £150 2nd hand- lasted 3 months, then same problem. Bought another from an '89 bike for 250 dollars off ebay + post and duty- well over 300 dollars. Been ok now for 6 months. I bought the earliest I could get as I figured if it was still working after 20 years it was probably a good one. Many bikes now seem to be going down with this problem- hence the high price....Steve

I've worked with LCDs and designed them for years.
They are a custom device that requires a replacement once the seals around the edges fail. They are made of many layers inside and out.

I have considered taking mine out and providing a reinforced seal from the outside but so far the work involved offsets my preventative measures.

So I guess I'll fall into that same trap once mine delaminates.

I'll probably work over any replacement I get before I install it. It seems to always give way along the long side of the display, which I would expect.

A small thin bead of "Welder" adhesive covered tightly by some Kapton tape should do the trick, I would think. Sure couldn't hurt any.

But once it starts, it's over kids.

Rudy, two quick questions. I'm replacing my LCD soon. What is "Welder" adhesive and Kapton tape? And how would you work over the LCD before installing?

Second, it seems to me that the "LCD Display unit" that Honda sells is the entire electronics with cables, etc. Is there any way to purchase the LCD panel itself and wire it back into the electronic circuit board? Does anyone know the actual supplier of that LCD panel and what would be compatible with the Honda electronica? E.g. resolution, etc? There are tons of LCD suppliers, of all sizes and resolutions. It seems to me that this would be useful to a lot of folks!

Mark.

The main problem concerning failure of the LCD unit is because folks leave the bike parked in the hot sunlight without covering the windshield. Due to the angle of the windshield and the angle of the sun at times, there is a very "hot spot" reflected on the LCD unit. And this causes warppage and LCD unit failure. It usually happens when the sun is shining from the rear of the bike, it hits the windshield then reflects the "hot spot" on the dash "at the LCD unit". And it doesn't take very long for the damage to happen. I keep a windshield cover in my trunk and use it when parking the bike in direct sun light. This problem happens more with the taller after market windshields than with the stock windshield. There is a significant difference in the angle of the windshield.

Answering the 2nd question first... that LCD, like most, is a custom mask made for Honda by some LCD vendor. Honda would be the only client they would sell that to since Honda probably owns the artwork used to fabricate the segments and the contacts that come out of it. They are literally produced for each customer in batch orders by contract.

Below is a picture of Welder adhesive. You can get it at Lowes.
Kapton tape is a very stable, high temperature adhesive tape that resists molten solder when used in printed board fabrication. It is very durable and strong.

The preventative procedure I would attempt would be to gain access to the edge of the LCD where the glass layers and seal can be seen. I would coat the edge with a thin layer of Welder and let that dry. Then I would make an edge wrap over all that with kapton tape to help seal it and to bind the edges together better.

That long side loses it's bind with age and heat. Moisture can also attack it.

Adding my two layers not only protects the factory adhesive but adds physical strength to the edge of the glass sandwich.

I've never seen kapton tape let go but it could allow air down the crack of the glass seams. So the Welder provides a good seal and flexible strength. The tape protects the Welder and the seal by binding it.

Kapton tape is available many places including here:

http://www.kaptontape.com/

You would want a width that can cover as much of the front as possible without showing out the bezel, plus the width of the edge and around to the back side up to about 1/2 inch without interfering with any of the contacts.

I figure 3/4 inch width is what I would start with.
1 mil base is probably plenty.

Thanks, RUdy! Looks like getting an LCD panel and wiring it into the assembly is not going to work. Darn.

I'll pick up some welder and tape before installing my LCD.

The subject of this thread was about an LCD unit for a 1999 Gold Wing SE.

Don't see any point in quoting prices for a 1989 Gold Wing as they are different.

Check HDL for the 1999 LCD unit part # 37130-MAM-A81, item # 14, you will see it listed for 375.58.

I don't think they are different as I fitted an '89 one to my '97 as a straight swap and can't see anything different about it- except the lack of the black semi circles of course! Steve
