Honeywell LCD fail and repair 

I was all prepared to replace my Honeywell CM921 and was actually trawling the internet looking for them when I spotted your RU-vid video. Got to say a big "THANK YOU"!! Followed it to the letter and now have a full screen again. Many thanks for a great video.

Thank you Grandad's Shed, we had put up with extremely poor display for about three years and worked through your video - end result ...perfect display. Simple and clear instructions. Used a hairdryer on it's hottest setting instead of a toaster. Brilliant!!

Its really useful and charitable of people to post these instructional videos and I'm sure this one would be very good. The problem is that the daft music, which is much too loud, completely distracts from the video and I can hardly hear the instructions. Also the music annoyingly increases and decreases in volume when the activity is fast forwarding. Having said this the gent has a quiet voice and this probably compounds the problem. Its soooo... helpful to have access to these videos and thank goodness people post them - just maybe in future it would be better to have the volume matched to the violume of the instructions. Anyway - Thank you "My Grandads Shed" good video.

Hats off, sir. Just baked the LCD of thermostat I've found after it's being in a barn for 10 years. The screen was dead grey, only some light in the corner. Three "toasting" circles (it was getting better with every time) and it's ready for use. Thank you!

I agree with ngorongok about the music and the audio quality - however, this video was super helpful to me in solving my problem with ghost characters on my CMS927 thermostat. I was planning to buy a new one - but the CMS927 is discontinued. Honeywell tell me it can't be repaired and recommend replacing with a Honeywell T4R thermostat (about £100) which then would need to be paired with with the installed receiver. This video (plus a bit of added ingenuity) has saved me all of that. My first attempt, using a toaster, failed but when I used a hair dryer and added a piece of shaved down ice lolly stick as square section packing (as at 7:04) it worked perfectly. I now have a fully functional thermostat with all digits and characters displaying correctly - and I've have had an enjoyable and rewarding afternoon. Many thanks!

One of my CM927s lost part of its display earlier this month. I watched this video and others and decided to tackle the repair once I was back from a short holiday. I took the batteries out and left the CM927 in a room which will have been quite warm in view of recent good weather. I am now home again. I replaced the batteries and was delighted to find that the display was back to normal. Of course, I have no idea how long it will be before there is another failure of the display, but my advice would be to not rush into dismantling a unit until you have given it a chance to auto-repair.

Tried this on my CM927 which had quite a bad case of failing display. Tried it a couple of times with a hairdryer and it ended up worse than it was originally. Decided I had nothing to lose so did it with a toaster for a couple of minutes and was amazed -- it's now perfect. So, the lesson I guess is, don't be afraid to give it a good toasting. Many thanks for the video.

Great video. I managed to follow it and in my own experience I needed to hold over toaster until discolouration - about 2 mins. On the first attempt I didn't hold over toaster for long enough. Great video explanation, despite audio comments, and saved me £120. Many thanks !

I thought I was going to have to buy a replacement unit and this worked, just used a hairdryer instead of the toaster. Thank you so much for saving me £100!

My mom's Honeywell screen had gone and before buying new I said let's look on RU-vid. Followed your video and now were doing a dance around the kitchen. You saved us 90 quid! Many many thanks. Whoop whoop! I owe you a pint 🍻

Brilliant - thank you!! For me this worked first time. I initially thought I may have overdone it, but it was fine after allowing to cool for around 20 minutes. I used metal clothes pegs and a toaster. Definitely need something to hold the unit towards the end of the 2 minutes as it all got quite hot.

Worked a treat using clothes pegs and hairdryer for 2 minutes. Thanks for posting...very helpful and saved £££'s getting a new controller.

Such a great help - thank you so much! I did exactly what you said and the problem is now solved. Amazing!

Thanks! I used your video and now have perfect working screen on the Chronotherm CM927.

Thank you, it worked! It is very nice of you to take time and modify the videos.

Thank you!!!! 200€ spared, worked like magic, same thing with a heatgun and wood pegs

heat gun and one bulldog clip. concentrated on heating clip (held with pliers) until screen looked like I may have killed it. worked a treat. saved me £200. for how long I don't know but see no reason it shouldn't last a good while 🤞. 1/2 hour pottering in my own grandads shed well spent. many thanks.

Un grand merci pour votre vidéo, l’écran de mon CM907 fonctionne à nouveau. Thanks a lot

Sorry but you do have to turn the music off, it totally distracts from your message. Thanks for the video though

Top video ,20 mins and carefully following the instructions and hey presto working like new,thanks.

Fixed a nice LCD radio signal clock with your clue of applying heat. I used a hair drier. Thanks for posting.

Thanks a bunch this really helped me, couldn't blive it it took me minutes to fix my fisher paykel fridge freezer display that totally stopped working, just took it out put it on top of the toaster not expecting it to work at all but to my amazement it just came back to life as it was a new unit, it would have cost me a lot to replace Thank you so much for the video

Brilliant, thanks! Worth persevering I'd say, worked for me on the 4th attempt.

Great video,. I tried first another video which state to warm/heat the LCD for about 20s above a toaster. Repeated this several times without any improvements. Since the lcd didn't work i tried to ready heat for 2 to 3 min's also to the point the lcd slightly colored darker. And after the second long heat the display did work again !! Many Thanks .

it looks like you've reactivated the conductive adhesive between the flex circuit board and the screen. Excellent work!

just saw the 'I have another video with the background music removed here: ' link - that is most appreciated .

Thanks! Just copied you completely - worked a treat. You just saved me £100+. There's a pint for you in Portsmouth if you ever come this way.

Thanks for the steps and toasting instructions! mine works great now!

Thanks v much! Sorted our CM907 - works like new. Used a hairdryer for heat source - 2 tries and back came the screen. No landfill or expensive replacement either. And music is fine. Jazz Club……nice! (Fast Show ref 😀)

I repair mine thanks to your video ! Thank you 👍

Hi,just want to Thankyou very much,followed your video to the letter,all singing and dancing again 👍🥰🇬🇧

Merci beaucoup, ça marche! Many thanks, it works!

Thank you for your video, managed to fix mine.

Tried this and it worked a treat, thank you for sharing, don’t go on EBay and pay money for a similar video

Smooth operating lad!

Just tried this on an Emerson 1F95EZ. It worked pretty damn good. Not 100% perfect, but pretty close. Thanks.

Thank You It worked on my 10 year old Display unit. Thanks Again

Absolutely fantastic, saved me £125. Took me three times, didn't have cue stick in the correct place and third time went with toaster heat for longer and just at pointed towards ribbon edge. You are a ledge.

I don't fully understand how this worked but it did! Thanks!!

Nice video, thanks god you posted a new one without this music. If you can speak louder it would be nice too. But thanks for your video! Helped a lot!

Repairing with a toaster. You are a legend :D

Great video. I have a question. I have the same problema with a digital termometer. Can I do the same work for ir?. Thanks

It totally worked! used a hairdryer instead of a toaster.... thankyou!

Brilliant, thank you. Perfect!

work very well, thx from italy!

Can something like this be done with a hot tub topside display. I can pretty much see nothing on the display. Sometimes very faint. Seems to be holding condensation.

You just saved me ~£100! Cheers.

Thanks for the video. Time to do mine, it's pretty awful now 👍😂

Appreciate sir , congratulations

Hello, maybe you can help me, I replaced the damaged lcd display of my Boafeng UV-6R. When I install a new lcd, it has a high contrast, only when the battery is low does it allow reading. Thanks

It works with my acc chek active screen thank you so much

I ended up buying the much cheaper 2-wire on/off version, which has the exact same screen module. That module works perfectly in the wireless CM927 version.

Hi there, don't feel confident at all doing this. Could you do it on mine? How much would you charge?

Thank you so much for this video, I am going to get this going during the weekend, but first, I wanted to see what those red and black conductor things are called so I could order some. Many thanks

Merci beaucoup , en 10 minutes j'ai pu réparer mon thermostat .

There are available in the market cheap soldering irons with flat tips for soldering especially these types of ribbon cable and also are available the cables since they are used widely in car dashboards for displaying various informations.This kind of repairs are time waisting because if not totally got broken it might or not work or even if works it lasts for a very limited period of time.

why dows heating the display fix it? does it fix the crystals somehow?

I have to work on my multimeter, which has some ghost segments. Thank you.

Thank you.

Thanks. I have followed the instructions. Easy to follow.. But I think in the glue between the screen and that white background has worn off and it flaps open 04:19 . What kind of glue i need to stick them together again if needed. Thanks

How many degrees do you calculate? I'd use a heat gun. Thanks!

So is the principle here similar to reflowing a motherboard?? - Do you think this would work on a dead smart phone screen?

Meu display LCD só aparece a parte de cima dos dígitos. Oq pode ser?

Same problem-Going to try it with soldering Iron and aluminum foil

Great video very informative but but I just used a hairdryer to heat the screen and ribbon worked worked a trear

Good video! Maybe would be better to use a heat gun with temperature control. It is a very useful tool for people that like to DIY.

Rated !

Very good, valeu.

Put mine in the oven and it worked 😂🎉

I’ve tried your technique to fix mine, but it didn’t work. When I press on any of the panel buttons the screen goes blank. I then have to shake it to get the screen back which is very annoying. Anyone got ideas what the problem could be? The digital display is perfect otherwise..

Are you able to repair my lcd

SOMEONE TELL ME WHAT THIS SONG IS?!?!?!?

Nice music video

Put the Cigarette Gelatin on the display conductor contacts. Then move the pen with a soldering iron to the right and left for about 1 minute, it will be fixed.

wath yuse film neme and tip

good video but ffs is the music really necessary?

Broken CM927

can not hear with nurve racking music

1:19 Looks like 2G

Pity about the irritating fluctuating volume of background music which drowns out the rather quiet speaking. I tried old Harry's method which worked.

Apparently Granda is deaf

Good instructional video but ditch the music.

Excuse me, are you interested in being our sales representative？

Combination of music and mumbling make is difficult to understand

How about either talking louder or having the background music volume lower? Do you actually watch the videos you make?

Them music is very high and yr voice is very low and we are in real trouble!!

music drowns out what you are saying.

the music is annoying

music is a pain

extremly enoying music

Your video seems good, no need of shit loud rock noise (music?).

The sound of music is annoying

I’m sorry, but I couldn’t watch it. The music was driving me crazy! What’s up with that anyway? Lose the music!

Wow, new low for audio quality. Yikes, that's bad. Kill the music, raise the voice audio level, and learn to talk out loud.

Take the music off and stop mumbling!

Annoying music in the background, 👎

That music killed it for ma - gave up watching

Good tutorial ruined by that annoying music sorry to say

GREAT MUSIC! 🤮 Now if we could hear the person talking....

Ruined by bad music, bad audio level, jumping all over the placed.
