Not able to read my LCD screen.

Post by Fireplow »



Good Morning, I have a 2004 GL1800 that has 33k miles. My OD is not readable during cool weather 67F and returns in the warmer Temps. 72F (these are approx. Temps.) has anyone got any ideals why?. The top is at approx. 67F and the bottom is at 72F. As the temp gets warmer the read out gets darker and vice aersa. This started last year during the cooler weather (what we have of it here in FL.). I haven't been able to find any discussion on this topic. Just FYI I am the second owner of the bike having bought it with just 18k on it. I have a short video of what happens when I add a hair dryer to the back side of the board. Watch the video here. [YouTube][YouTube][/YouTube]

That type of issue can happen with old LCDs. Your YT link didn't work.
Depending on what is wrong in the LCD stack, you might be able to fix it. If not, replacements are still available.

Thanks Rambozo I couldn't get the YT to post for some reason could never figure out how to do it. I have ordered a new one and it should be here in a week and a half. I messed with it off and on all day. I did find one place with a flash light (using it as a heat source) that when it got warmer it worked. I looked as close as I could but nothing jumped out at me. So I ordered it.

Thanks again

For next time, to post a youtube video, you should be able to copy and paste the link.

Thanks for your help. Here is the video I was trying to show as a test.

Well good morning, We have a working LCD again(new). As promised I did try and find the problem with the old LCD. I have concluded that I can not pin point the problem but I have how ever narrowed the area to the middle of the board and this is how I did it. I took my hair dryer and warm up the board using a piece of cardboard to isolate it in 1/2 and in 1/3's. When warming up each side the board would work. When it was warmed it 1/3's the board worked but not as fast. So I took and narrowed it down to the middle of the board by using two pieces of cardboard to isolate the middle of the board and it worked. I also took frozen spoons and held them next to the area and sure enough it would fade away. So something in the area is either bad or loose. I am referring to the area between the pin connectors and some where near the VR501 label. I didn't want to touch anything as I didn't want to screw something else up. (that would be my luck) I did try and video the process but not having a way to hold my phone in the area I wasn't able to do it. (there isn't much room to get the screen on camera)

I took this quote from another board that will explain it a lot better than I can.

This came from techdude2000
"Thanks for the follow up. My guess would be either IC501 has become temperature sensitive or one of the surrounding electrolytic capacitors(silver/black metal cans) near it has changed value and become temperature sensitive. We used to see this a lot in TV chassis."

I hope this quote doesn't upset any one but spreading info around is helpful to all. You can see the components he is referring to in the pictures. I also found out my method in looking for the problem wasn't to far off as he also explained how he uses the same method himself (with out the spoon and hair drier) to find the component that's at fault. (They use much refined tools)

Thanks to all of you that gave input and followed along.

It's surface mounted components, you could have a small crack in solder that closes up when it gets warm, and opens when it cools off.

If nothing else is working, you could try putting it in a small oven at 450F for a few minutes, which will melt the solder. Then open it and let it cool before touching/moving the board. If there are any cracks in solder, that should fix it.

If you have a heat gun with a concentrator, you can try directing the hot air at the components in the area you identified as being the problem, with the same aim - reflowing the solder.
