Infotainment System - Blank Screen

I have a 2014 GMC Sierra with the infotainment system. The main screen went black yesterday but everything still worked you just couldn't see what was on then screen. I figured it was just a one time glitch because the system is known to do odd things like that. But it stayed blank when I shut it off for a while and even disconnected the battery for a while and still nothing. Has anyone else had this persistent issue or a similar one to it?

There is a software calibration for this that also fixes a lot of Bluetooth issues.

I have a 2014 myself and have had that happen 3 times so far. It usually comes back after a little bit. I am waiting for an oil change to tell the dealer. I hope the update also fixes the voice commands because 75% of the time it doesn't get it right and I try to speak as clearly as possible.

Yeah I thought it would come back after a while to. Its been three days straight and I have disconnected the battery over night twice and the lcd has not come on at all. I think it might be more than just a software issue because i have had it black out before but it usually comes back on if you restart the vehicle. Im anxious to see what my dealer is going to have to say. And yes the voice command is usually a hit or miss with me to.

This just happened to my 15 today. Won't come back on at all. Have to see what dealer says. This truck has spent more time at the dealer than my last 6 trucks combined. Ridiculous.

I had this happen on my '15 2500. First time it went out on Monday AM, stayed out through to Thursday when I got truck into the dealership. They said the reseated a connection and added dielectric grease. Went out again the following Monday morning. Tuesday morning it was working, took it into the shop anyway. The found a bulletin for "a similar problem" which involved adding one or more additional grounds to a BCM, they didn't go into details. While they didn't tell me or document it; I know they found an additional loose connection behind the dash. Banging on different parts of the dash would cause the display to come on/off.

Initially, the mechanic tried to blame my accessory switch box and aftermarket backup camera.

New owner of a 2014 LT with the 8 inch infotaiment screen. As it's a used truck, i figured I would need to replace the cabin air filter. When I was done, I turned the truck over and had like you described - black touch screen, but I could press the screen and stuff would happen....

 

Removed lower glove box again, started truck and screen comes on. With it running, I put it back in and as I pushed in the lower left corner the screen went out. Seems like there's a harness in there that can get pinched. Totally weird, but totally happened!

 

Made sure to insert the box slowly and this time it stayed lit; so all good and no reason to go to the dealer and go crazy...

I had this happen to me this summer. The 8" LCD display would go out completely at random. Only restarting the vehicle would correct the problem. The issue could not be reproduced on demand. Visited the dealer twice on this issue. They could not reproduce. So I took a pic of the issue with my iPhone to show the dealer. I also got GM customer service involved and they reached out to the dealer to figure out an action plan. They couldn't reproduce, yet they had the photo showing the LCD completely blank. The XM radio continued to function though through the steering wheel controls though the responsiveness of changing XM stations changed to 5-6 seconds lag time to go up / down 1 channel. The first trip into the dealer they reflashed the firmware, which the dealer stated was based on guidance from GM. The second visit they told me nothing was wrong, which is the point I complained to GM customer service. Who I must add they were extremely helpful in getting this resolved.

 

Ultimately, the GMC dealer replaced the 8" LCD display with a new unit.

 

The problem has not occured ever since and is completely resolved.

Just used this method and it worked. I too did my cabin filter and the screen went out. I started the truck and moved the wires around. Screen came back on. Thanks

    • This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.  
    • 2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.  
    • Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
    • Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
