Wow, thank you! Your video is now 8 years old, and my Matrix XR is still running perfectly after 19 years... except for the clock. It's been getting worse for the last 10-12 years. Time to crack it open!! : )
Had an airbag sensor bad light on my 2005 Toyota Matrix which was on the same circuit board at the clock. The clock was also dim/off most of the time. Followed the instructions in the video which fixed the clock AND the airbag light on the dash. THANK YOU for making the video. Had the car to the shop twice before and they couldn't figure out the problem.
Did this on my 05. The hardest part of the repair was getting the 2 screws out. I did not have a TORX, so used a small flat blade screw driver and pliers o n the handle. I used a 15 power Zeiss eye loop to see that at least one resistor had indeed a cracked looking solder joint. I heated each resistor with the soldering iron for good measure and each of those 30 pins or however many there are. Works like a GEM! No need to spend $144.00 for a rebuild unit on line or more for a new one. Thanks you!
Thanks for the post. I had this problem and found that the through-hole pins on the display were incompletely soldered from the factory. I reflowed the connections/added solder as necessary and it was better but it didn't fix the problem completely. I noticed the display would dim/brighten at different times, I figured that the voltage to the display was varying too much and that the capacitor on the board (the silver cylinder - 47uF 35V) was also problematic. I reflowed the solder for the capacitor and all the other resistors labeled R_(number) and now it works perfectly.
Thanks for this very helpful video, pentaxk110d. I just spent about 20 minutes or so doing exactly what you demonstrated (also heating up each end of the rectangular resistors that can be seen at the 2:00 mark -- #270, etc.). I then re-installed the clock assembly in my 2005 Matrix, and . . . PRESTO, the clock showed 1:00, and I proceeded to set the proper time. Previously the clock was off entirely except for rare, random displays of the time. As you suggested, I did not add any solder to any part of the clock assembly, just heated up all the parts you indicated. Thanks again! P.S. By the way, I tried this a couple of days ago, but it's now obvious that I didn't heat things up well enough.on my first attempt.
There is a conformal coating on the board. Its best to scrape it of before reflowing the solder. They use a lead free solder ( RoHS directive) which over time cracks/separates because it cannot flex.
@@paulbjarnason4696 As you have observed, the fix to these dim or no clock display issues is not the display. Its the resistors for the display that need reflowing. The same goes for the other models of Toyotas.
I just did this on a 1994 Toyota Hiace. I also re-soldered some other areas on the board while it was apart. Fixed it perfectly. Great video and thank you......Cheers from Australia!
Thanks so much for the video. On my Matrix the screws were a Torx 7. I reflowed the connector pins first...and no joy. Poked around the resistors and found one loose. Reflowed the resistor, now the various LED warning lights all worked...but no clock. Plugged it is and poked each resistor and found one under the display that if I poked at it... the clock would light up. Reflowed that one....and the clock worked, but with some dim numbers. Holding the circuit while it was on, I felt some resistors getting hot, so I reflowed every resistor I could access. It now works great at full brightness. Lesson learned, just reflow every resistor that you can access. They may look good, but a bad connection and the display will not work, or will be dim. I also recommend you use very good flux on your reflows. I bought AMTECH NC-559-V2-TF. Works great and the syringe will likely outlast me!
Thanks, I've been wondering about this for a while, banging the dash worked for a couple weeks but now it's just dim all the time. I've got a lot of free time at a maintenance shop so ill make sure to bring my clock in.
It worked! I am not handy...but I followed the instructions in this video and fixed my 2005 Matrix clock which has been out for 2 years or more. Curiously, the repair did not appear to work when I first reassembled the dash and turned the key to accessories. But the next morning while driving the car, I noted that the clock was working. The digits are bright and strong. Thank you pentaxk11d!!!!
Glad it worked for you. I find that my clock goes through brighter and dimmer seasons, but it can also be affected by battery and alternator condition.
Ok so I wish he spent much more time on the solder part, I have soldered copper pipe before with torch, but never used an actual solder gun with tip, are you supposed to see any actual solder come out or just lightly touching each contact?
KgreProductions Annoying to say the least! Hopefully you can get yours figured out. Apparently all of these clocks were bad for this and the majority had the same issue with the soldering.
Hello, Great question. Just long enough to melt the solder. It will get shiny and look a little bit liquid. Just not so long that board starts to heat up and melt.
@@pentaxk110d Thank you. I did it and your description fits what it looked like after I was done. The first couple of days after doing it the light was still off but after a couple of days it now shows a strong consistent light. I hope it stays that way.
@@kelvinvillar9984 Me too! Thanks for watching. I'm just a guy- neither a mechanic or an enthusiast- just trying to learn things and help a few others along the way. There are some other helpful comments on this thread from others who have had good success.
Great Question- I'm not 100% sure. I've heard that the clocks have been an issue on many of these vehicles in this era (particularly the Corolla, Matrix, and Camry). I have heard that it is just how they were all made. It is quite likely that an OEM replacement clock would do the same, though Toyota parts typically come with at least a 12 month warranty. A replacement clock, however, could be in the neighbourhood of $75US
I personally prefer the factory look of the dash, but that would be a more economical option. There are some after market clocks you can buy, but the quality it’s not regulated, so beware!
I’ve Use the same method on a few different Toyota vehicles. The only difference would be getting the clock itself removed from the dashboard. The soldering, etc. Should be the same. There have also been a few suggestions on this thread to check alternator function. If it’s not charging properly, it can impact accessories like the clock.
PJ Grl thanks for your comment. I highly doubt that your starter and your clock problems are linked. I can't see any way that the two issues would be connected. Coincidence?
I'll give you that; I'm no pro RUclips, but what can I say? One dark, rainy, late night in my parkade, I found a way to fix my issue and decided to share with other frustrated Matrix owners. I hope you at least found it helpful 🤷♂️ Cheers
Certainly could be. Corollas, Camrys, and Matrix all had similar issues in this era. A factory replacement clock can be upwards of $200, so look around for a used one at an auto recycler first!
Ej2o13 this happens with many of the Toyota vehicles from this era. Accessing the clock on your Corolla will be slightly different, but the soldering technique should work the same. You can also try addicting additional solder to the contacts- just not too much!
These clocks are notorious for this. While a weak alternator could cause this to happen, there would be other symptoms as well such as a dead battery or other accessories working intermittently. In this case it was solely the clock at fault.

Love the toyota
Still not working even with heating up all big resistants and connection teeth.
Why did the solder joins go bad?
How long did you soldered each tip? I’m not trying to over solder it and possibly do more damage .

@@pentaxk110d $260 plus US at a Toyota dealer. You might as well put in a great mid range stereo with a working clock for that price.

do you have any video for fix toyota hilux ln166 clock?
My clock is doing that too. My starter went out too this week so replaced that. Do you think the two things could be connected?
PJ Grl thanks for your comment. I highly doubt that your starter and your clock problems are linked. I can't see any way that the two issues would be connected.
Coincidence?
I have replaced my alternator on my 2006 Matrix. The clock lights up again. I think it is due to the voltage issue.
No how-to video is complete without low light, someone blocking the picture, or the main part already having been done 😄
I'll give you that; I'm no pro RUclips, but what can I say?

My clock is not dim, it's completely dark. I tried your instructions here the best I could, but it didn't work. Think the clock is just dead or what?
I tried it again today and re-soldered ALL the joints, including the resistors and it WORKS now!! Wooohoo!! Thanks so much!
