Mr Coffee model BVMC-PSTX91 display is almost gone, this is how I repaired mine. The led backlight does seem to be a problem on these coffee makers, we've had to throw out at least 3 of them in the past but they are still our favorite coffee maker.
Note to self: I'm getting about 5 months of good brightness, I measured the led at 20mA so I've added a 47ohm resistor in series dropping current to 13mA

you're a YT creator now, Chris!

While my light is dim too... I need to know how to get the heater out. Can you tell me how, or do a video. Thank you. And I agree...Best coffee maker I've ever had.

Thanks!

Thanks. I replaced mine tonight and it was fairly easy despite all the screws. The 2 screws at 1:00 were completely corroded, so I had to drill them out. Luckily there was still enough left to twist the screws out with a small pliers. Thanks again - - I can use delay brew now!

Good to hear, they are too good of a coffee maker to just throw out.

Hello Chris. Great video. Do you know the SMD Led dimensions that you use to fix it. Thanks a lot.

@chrisingram7277 2 года назад

Thanks Alejandro, I used 1210 smd's (www.aliexpress.com/item/32825796287.html?spm=a2g0s.9042311.0.0.27424c4dbvariV) but they were a bit large and I had to trim the plexiglass. 0805 's might be the right size.

@chrisingram7277 2 года назад

And it's still working great:)

An 0805 is larger than original, but works well w/o any mods. [FYI: Green dot is the cathode (K) on SMD package, and the diode board is marked A & K.] {Believe the original was a 0402, but it buggered off before a measurement could be made.}

Hi Chris! my mom got the same coffee maker and never used it. It doesn't seem to work, so I'm trying to diagnose it and fix. This machine has an insane amount of screws! However I'm not able to disassembly the side panel, seems like it has two plastic pins (or screw covers?) on the back. I wasn't able to got those out and pop the machine open. Any ideas on this? It's driving me nuts and don't want to break it (or maybe I do). Thx.

@chrisingram7277 3 года назад

I was surprised how many screws there were too, from what I can remember the sides stayed but there was an access hole to remove the power supply. Does the coffee maker almost work?

@yoqeriaponerminombre 3 года назад

@@chrisingram7277 It doesn't turn on at all. It's a real shame since AFAIK it was never used. Where's the access hole to the PSU? I didn't find that neither. I'd love to find some disassembly instructions although most certainly those would not be public.

@chrisingram7277 3 года назад

I couldn't find any info either, but from what I can remember, once you get to the clock PCB, the rest wasn't too bad.

@chrisingram7277 2 года назад

Did you have any luck fixing your mom's coffee maker?

@MichelleSmith-ig5xv 2 года назад

It goes to the clean button how do I get it to make a pot of coffee

@chrisingram7277 2 года назад

On our machine, we just push the round button(brew on / off) and it works or we use the timer.

@kiwik90 2 года назад

Can you do a totorial on how to rip out the speaker that makes a smoke detector sound when coffee is done?

@chrisingram7277 2 года назад

LOL, we're upstairs in bed and barely hear it, my wife verified that there was a beeper.

@trankos2367 Год назад

Hi , I have the same problem the display doesn´t work at all, Do you think it´s necessary for the screen to work in order to make coffee well? I tried it with just water and it heat well.

@chrisingram7277 Год назад

I think it should work fine, it only prevents you from using the timer.

@trankos2367 Год назад

@@chrisingram7277 I turn off al the lights and I can see the screen jejeje

@chrisingram7277 Год назад

@@trankos2367 That's what my wife would do to set the timer, wait till it was dark at night:) eventually I'd put in a new led and get more life out of the coffee maker.

I'm not sure why this comment did not come through on YT so thought I paste it here.: Darryl Chris - Thank you for this video. I was able to take apart my coffee maker and replace that faulty backlight thanks to your instructions. Instead of replacing just the LED, I replaced the entire backlight with an Adafruit 1622 (size medium ) backlight module off of Amazon. It is 23mm x 75mm so must be cut to the required length. It is also about 1mm too wide as compared to the original, but I found it still fit OK, although tightly. Here is an Amazon link to the part: www.amazon.com/White-LED-Backlight-Module-Medium/dp/B00R5CDHNI REPLY MANAGE ALL COMMENTS

@jessekolar322 2 года назад

Thanks! You mentioned medium was tight, so I selected the smaller size on that link, but it didn't quite fill the space and although it worked, I'd recommend going with medium to light the entire screen. Great almost direct replacement.
