pulsating touch screen

Hey folks, I have a 2015 SR5 double cab, standard entertainment system, and lately I've been getting a very intermittent pulsing coming from the touch screen. It's not all the time, but probably once a week honestly, the display screen just pulses, almost like it's just flicking a switch. It doesn't go off, it just goes a little darker, but we're talking probably ~1-2 times per second? It's a very steady pulse. Don't really know what's going on. I'm probably going to set up an appointment with the dealer since it's still under warranty, but I can't recreate it on the fly. Any ideas what I might be dealing with?

At 4 years, my 2013 JBL/nav head unit rebooted itself intermittently.

I replaced it with a Kenwood keeping the stock speakers and amp.

Huge improvement. Fixed the problem.

Electrical connection is failing intermittently, either to the console or to the LCD display. I would look for other reports of a problem like this for year 2015 Toyota vehicles, and don't limit your search to Tundra trucks.

Does it flicker like maybe when you turn the headlights on and off?
Maybe there is a bad connection in that illumination dimmer wire/circuit.

As @4dailyrunner suggested, replacing that Entune with a decent aftermarket HU of your choice goes a long way in fixing that and other issues of the limitations of the Entune.

Yeah, I'll have to play with it a little bit and see if there's certain times it does it or not. Kinda look for a pattern I guess. As of right now, unfortunately an aftermarket system is not even in the cards for me right now. Plus, I still have warranty for 125,000/ 8yrs, and I'm only at 76,000/ 4 yrs. I'll hope for the best. I have to figure out what else is going wrong now, because my phone doesn't pair correctly with it anymore. Haven't gotten a new one, and any updates I've had, It worked fine afterwards. I tried deleting the truck and phone from each other and tried re pairing a few times, but it won't sync my contacts or dial anymore. Getting kinda irritating, lol. Might just make a trip to the dealer this week... we'll see.

If you have that kind of warranty, use that $&@):; thang!!!

Heck, nitpick the crap out of the truck every 4 months and make a list for quarterly visits!!!

Have them replace the air in the tires with OEM air!!!

LOL!!!
