Pixelated lines on 14” infotainment screen

Just started the truck after filling and the screen was filled with pixelated lines across the entire screen. Restarted the truck and they are still there. Drove for a bit and they went away, and then returned. Is this a known issue, is there a thread on it? (I didn’t find one in my initial searches but could easily have missed it). Not angry yet but not happy. Thank you for any guidance or recommendations- T

 

Thank you Ryan! This occurs even during boot-up (initial Toyota logo, etc). I’m considering whether disconnecting the battery/then reconnecting might help. Will try and test. Any way to reset the infotainment system?

 

Holding down the volume knob for 5 seconds or so reboots the unit. Not sure if that’s what you meant by full reset.

 

Much appreciated gentlemen! The 5 second volume knob press worked to restart the unit. The screen is filled with gibberish and alternates between pixelated lines and simply going dark, then back on randomly. I’ve been taking video and will bring it in.

 

Sounds like a bad head unit. I have not seen nor heard any other reports of that issue. Hopefully the dealer gets you squared away quickly.

 

Continuing the reset thought, what is the process for fully disconnecting the battery to reset the entire vehicle, or other recommended ways to fully reboot the truck? Shall I just disconnect the negative terminal? There are also plugs connected to the battery in addition to the terminals, also disconnect?

 

Thanks Ryan, I corrected my post

 

Thanks again Ryan, I performed the system reset, that worked, and I was required to reconnect my app to my account, and then again to the vehicle. Many thanks for the instruction. Unfortunately my issue persists with pixelated lines through the screen, intermittent screen shutoffs, and general malfunction. Will visit the dealer.

 

The pixelating looks like its a hardware issue, not anything in software. Taking it to your dealer is your best bet

 

I just had my entire infotainment system replaced at the dealership. The screen is now working well and the resolution has been restored. I was able to reactivate my Sirius subscription.

I’m having challenges getting my app to connect with the vehicle, and the infotainment system won’t let me log in. It does not recognize my subscriptions.

The only other option I can see is to remove my vehicle from the app. However, app indicates that removing vehicle will cancel all my subscriptions.

“Register profile” is greyed out in the infotainment, and my app is still saying the vehicle’s doors are open (state of vehicle when original radio was removed). I am grateful for your advice.

 

Dam dealer should of walked you through that!

 

Updates, I had an excellent talk w/Toyota Brand Engagement who checked w/Toyota Connected Services tech team. Their instructions were that the Dealer must perform a VIN sync process through TechStream. In situations where the entire head unit is changed in the vehicle, they have to associate the VIN with the new head unit. Dealer needs to call the Dealer Only Hotline." My dealership has been in touch w/this team and they are learning how to perform this process (first time for them). Will keep you updated.

 

Thank you Ryan! Can you direct me to the screenshot? I will share that with the dealership ASAP. I think they need all the help they can get!

 

You'll see alot of that with Ford having to match the Vin number on all the control modules but use other programming not forscan. I work for TMH toyota material handling (fork trucks) and we have so many different programs to use depending on engine/electric/pallet Jack's order pickers/lithium ion batteries. That's five different programs I had to install and have the right cables too, I think the auto dealers have it a little easier imo. Today I was getting the program for Colombia cart as they use a borgwarner controller so that's another cable and software I need to learn. There is more but I'll stop here cause my brain hurts lol.
Your dealer should of known about matching the Vin imo and I hope they make it up to you for your time. Now adays it's more that replacing parts. Thanks for the update too!

 

Ryan I think this is the thread that best matches my situation. I am going to spend some time reading this. Thank you in advance for all the help you provide all of us on the forum! https://www.tundras.com/threads/replaced-multimedia-screen.118695/#post-3048893

PS- I shared the detailed TIS instructions with my dealer. It seems incredibly straightforward. Pretty crazy they provided me with the new H/U without synchronizing to my VIN.

 

After providing the information above (thanks Ryan!) for synchronizing my new head unit with my VIN, my dealership studied the process and called me in yesterday.

They synchronized my H/U, got me connected to my Toyota profile and Connected Services and out the door in 30min.

Although it would have been even nicer to have had this done when the H/U was installed, it was a painless process thanks to the help of all of you on this thread! Many thanks guys.

The new H/U is working perfectly and the truck seems to be super responsive…might be psychological but she’s running better than before (to me).

Last question- based on model number etc can I tell when this H/U was manufactured?

 

Yes this is a known Toyota issue. Dead head units from 3rd party Panasonic manufacture. I started a thread long ago about this, i think i was the first actually. Toyota will warranty replace this unit. Just take it to the dealer. If the dealer acts like they don't know just tell the shop foreman to call the Toyota FTS for the region and they will confirm it for repair. Multiple cases have been confirmed just not enough to warrant a recall. They are honoring a replacement though. Takes about 2-3 days for part to come in and 1/2 day to replace.

 

Had the same issue when i did mine. These techs dont know how to check anything these days without instructions to do so. You'd think they would power the thing on to confirm it was working and see that message.
