Dodge Ram Cluster 7 in LCD Repair

[@jeffescortlx]

Update: No need to worry about the LED backlight transistors not turning on. It's just Chrysler doing what Chrysler does. The backlight needs to be triggered by the vehicles LIN bus.

[@nathanwahlert8620]

So if the backlight is triggered by the LIN are we looking at an issue within the body control module? Have you found a way to test for the backlight command at the cluster?

[@jeffescortlx]

@nathanwahlert8620 no the issue is still failing LEDs in the LCD. But it just makes bench testing more difficult since it requires a LIN command.

[@rpsmith]

Just to be clear for everyone, LEDs are current devices so once they turn on the voltage varies very little but the current can vary a lot so current is what you need to be concerned about. Thanks for the video!

[@jeffescortlx]

Yes very true. I'm assuming the maximum voltage of these back lighting LED's are 3.3v. So at 3v it's not possible for the LED to over current. Just assuming so I could be wrong. But I did let the cluster run for a hour. And if I end up being wrong, I warranty my work so the customer won't be out anymore $$.

[@jeffescortlx]

I haven't come across a full tutorial on this one that I know of.

[@nismofan740]

excuse my ignorance, But from what I gathered is that as long as my back light is still working, and only flashes/flickers when at full brightness I have a bad led. And I can just replace the screen (found some online between 70 and 130 bucks) If doing so would I loose my dimmer function as well?

[@jeffescortlx]

No just replacing the LCD screen will not make you lose the dimmer function. You'll only lose the dimmer function if you bypass the transistors like what I did in this video.

[@tiagoramirez9172]

Good evening Thanks Jeff for another great video. I fixed one of those a few weeks ago, different issue, (faulty stepper) not sure if this will help but I noticed that the lcd back light doesn't turned on while testing on the bench but it did in the truck.

[@jeffescortlx]

Now that's strange.

[@russellhltn1396]

Perhaps it needs data from the truck's canbus or other line to know how bright it should be. I'd think the brightness would be driven by the headlights on/off and dash dimmer settings - all stuff external to the gauge cluster.

Interesting. In my 2020 Jeep Wrangler I made a dimming adjustment on the way home from work. The next morning the screen was gone. The "black" screen will change to dark gray and back to black with the dimmer control, but that's all I've got. Wondering if I have the same issue. If it is CAN bus related, are you saying there's a driver or other component in the cluster board somewhere causing it? But it doesn't sound like you know exactly what or where it is? I already had a mechanic try updating software, $400 for nothing. I have a used one from a wrecked vehicle on the way, but it sure would be cool to fix mine.

[@jeffescortlx]

If it uses the same 7" LCD as the Ram/Durango then it's probably just LCD screen failure. I've seen both image and backlight failure in these Chrysler screens. It's not the cluster PCB LED driver circuit, it's fine. Chrysler just uses its special can bus to turn on backlighting.

Next time you work on a diesel ram cluster, could you see if it's possible to isolate one of the mechanical gauges so that it could be hard-wired to a different component? I.E. using the oil temp gauge as a level gauge for an aux fuel tank, or as a pressure gauge for an air tank.

[@hoaxs1939]

Just a thought on no control on the transistors. I would suspect the cluster needs know headlamp status / sunload sensor(DTRL)/ dimmer position(s) on what ever protocol it communicates on to output the correct pwm. If that was the case, I would suspect faults codes and maybe default to full brightness??

[@hoaxs1939]

Bummer it was an expedited reapir. A+ on the repair and troubleshooting.

@@hoaxs1939 interesting find, says "This problem will be repaired by an upgrade to the software for the instrument cluster". Maybe this model suffers from both hardware (LED failure) and software (backlighting not getting turn on signal).

[@kensmith174]

Do you know what each of those 2 transistors control? My truck has this cluster. The cluster backlight operates in one of two modes. When the headlights are off, the backlight is fully on and it's brightness is not-adjustable. When the headlights are turned on, the backlight automatically dims down, and becomes adjustable via a knob under the headlight switch. I was wondering if perhaps one transistor controls several LEDs, with variable voltage depending on the brightness rheostat? And perhaps the other transistor is simply on/off, powering the additional backlighting when the headlights are off? If so, I could possibly cut the circuit that controls the flickering (headlights off) LEDs. Since that additional backlight isn't necessary, the lower intensity backlight that's active with the headlights on is plenty bright enough for daytime driving.

[@jeffescortlx]

One transistor controls the top half and other bottom half.

[@kensmith174]

@@jeffescortlx That's interesting. I plugged the disassembled cluster into my truck, and all of the LEDs were flickering simulteneously. So, that means both circuits are driving flickering LEDs. The probability of both transistors failing simulteneously is nearly zero. I installed a used, replacement cluster, which resolved the issue completely. No flickering at all on the new cluster. That all of the LEDs are flickering would seem to eliminate the t transistors as the problem. That the replacement cluster resolved the flickering problem eliminates programming, or power supplied to the cluster as the problem. So, I guess I'll look for the part that provides input voltage to the transistors. Some kind of transformer or other device, that reduces the trucks 12v to the 3v feeding the transistors?

[@jeffescortlx]

@@kensmith174 I'm 99.99% sure the flickering is because of a failing LED in the LCD assembly. I would not expect the problem to be from a transistor or the signal/power feeding it.

[@kensmith174]

@@jeffescortlx Ok. So, the LEDs are in series? As one starts to fail, it effects the current supplied to the others? When I had the disassembled cluster plugged into the harness, and the truck idling, I could clearly see all of the LEDs flickering together, in sync with each other.

Hello, I would like to know if this cluster can be adapted to a 2012 Ram 1500

[@jeffescortlx]

This style is for 2013-19. I'm not familiar enough with dodge clusters to know all the changes both physical and communication wise to say for sure how compatible the 2 generations are. I'm pretty sure the older style has about double the wires coming out of it. So you might lose keyless entry for example.

[@thirdgearboogie2210]

I have a 2014 Ram with this exact cluster. The backlight on the LCD keeps fluctuating between light and dark. At first I thought maybe the light sensor was faulty, but if that was the case my headlights would be turning on and off. I guess I am just not sure where to look from here for a diagnosis?

[@jeffescortlx]

Your instrument cluster has the same issue as the one in this video.

[@thirdgearboogie2210]

My issue seems to be different than the issue that you corrected. I can still physically see the information on my screen it doesn't go completely blank. It just gets lighter and then brightens up again. It's almost like it is auto dimming.

[@jeffescortlx]

@@thirdgearboogie2210 There are two channels of LED lighting. It sounds like you have one channel that is still fine, but the second channel is becoming intermittent. So when the intermittent channel goes out, you're down to just 50% of the backlighting. And then when the intermittent channel comes back on you're at 100% back lighting. If you give it enough time the good channel will also become intermittent and it will go completely black.

You're looking at the wave of the future, here, people, and this isn't even an all screen cluster from a current generation truck. Thirteen hundred dollars is a bargain compared to what it's going to cost to replace all-LCD clusters in the newer trucks. Manufacturers are going to all screen clusters faster than you can say "cha-ching." I actually prefer the old style analog clusters, and those are going away. Can't wait for someone to send you a screen from a 2021 Cadillac Escalade. Wait 'til they get the bill for that monster.

and how are you ??? OK ??? greetings

Driver module control from headlights switch ,I have schematic ,

[@jeffescortlx]

So if it doesn't receive a dashboard backlighting percentage signal it just doesn't turn on the LCD at all?

[@luisagonzales1442]

Thru can buss I believe, how do I send schematic

@@luisagonzales1442 I have the wiring diagram now thank you. But it doesn't appear to show the LCD backlighting circuit, just a generic lamp circuit. I still don't know why the LCD would be completely turned off, even if the back lighting is set to minimum the screen still needs to be seen.

@@jeffescortlx there's a common problem with this style pick up ,reboots at no frequency and won't turn off upto overnight

And I thought my Audi cluster at 500-600 was expensive...

[@Qusin111]

oops this may be very bright at night

[@KACPER050599]

I would install an 555 timer dimmer circuit and hide potentiometer somewhere near/under steering column. It's a hack, but still better than 1300 bucks for a new cluster

[@jeffescortlx]

As Louis pointed out, it might be looking for a can bus signal to even turn on the LCD backlighting. So there could be nothing wrong with the backlighting circuit.

Just put a dimmer switch from home Depot somewhere lol....

You could have saved a bunch of money and effort by just buying a "FOR SALE" sign for that Dodge, and upgrading to ANY other truck. Even the Asian trucks are better than the Ram. Sorry, sometimes the truth hurts, but it's for your own good!
