    I may be missing something very simple after all this time (and if I am, my apologies),
    is there any way to shut the VDS display off while the car is plugged in?

    Year after year of being on every evening, I wonder what the lifetime and / or display degradation rate of the display is?
    Any display specialists that can comment on typical lifetimes of the technology used
    in this particular display?

    Many thanks-

    I think they use LCD and my experience is they last a VERY long time. I for one am not worried.

    To my knowledge, there is no function to shut off the screen while plugged in.

    The only defect I've noticed in VDS screens varying by car (I've now owned three Roadsters and regularly look after a fourth), is that the screen's colors & contrast seem to fade over time. My first 2.5 (VIN1213, 28,000 miles) had a much lighter and faded VDS screen than my 2.5 (VIN1438, 10,000 miles), which had excellent contrast and colors. Also, they were both on the same Contrast settings, which can be adjusted in the settings screen. It's not drastic, but there was clearly a difference in screen quality. Perhaps direct sunlight has something to do with this, too? Not sure.

    I also haven't heard of any VDS screens needing to be replaced. Seems like a relatively uncommon repair...unless any of us here on TMC have had that done. That would be interesting to hear about!

    dhrivnak and deedwest, you both are probably right, LCDs last a long time and probably not an issue. I guess we could just ID the manufacturer of the touchscreen and download the lifetime spec for the display. There is probably an abundance of data. My instrument (not VDS) LCD had to be replaced, but that was likely a manufacturing defects vs a wear-out issue. Many of us have LCDs running continuously at work etc for >5yrs, but as we push 10yrs and greater? I don't even know what type of LCD technology it is. Just thought I would throw the question out there for those who are planning to hang on to their roadsters for a while and may be wondering the same thing. Many in this forum have pulled their VDS screens, especially the 1.5s, maybe someone noted the make/model?

    LCDs have a typical lifespan of 60,000 hours. There are 8760 hours in a year, 60,000 divided by that number is 6.8 years if left on 24 hours / 7 days a week. I'd be more worried about the battery going out from a natural healthy life before that LCD. Only thing that has me worried over time is the NAND in the VMS, that has a limited life-cycle for writing, error recovery and wearing. And when that goes, so does all or most of the code running on it. I also know that Tesla didn't have the best source revision control for the Roadster and hopefully there's the ability to rebuild the operating system, drivers and application code back from scratch come when we need it in the future.

    That's not very reassuring. I think most Roadsters are already that old.

    Thanks for the lifetime#s, wiztecy. So about 14yrs with evenings on and a few days, not bad. 7 years for those who keep it plugged in and drive it little, that's about now for some.

    100% agreed, many other concerning items in the roadster. If there was a simple way to shut off the screen while charging, it would just be one less and an easy preventive step . It's not so much having to replace the VDS screen but more of the parts supply as we go into the future for those who plan to keep the car.

    Interesting about the code for the roadster OS.. hopefully all aspects of the roadster are starting to be archived correctly at Tesla for future reference.

    Our VDS screen has gotten out of calibration. I tried the calibration screen but it does not correct enough. I must now press to the right and above what I really want in order for it to work. This is a problem when the desired touch point is at the far right of the screen and also makes it a bit tough to get into the service screen. I pulled the VDS and examined it but see no obvious defects. Service quoted ~$650 for new part.

    can you please post some pictures/manufacturers/part numbers, perhaps there is a visible manufacturer for the resistive screen and the parts can be sourced and rebuilt?

    While not too difficult to remove, at the moment mine is installed and I do not have plans to remove it. If and when I do I will document and post here. Perhaps someone else has one 'on the bench'.
