YEP!.. Looked EXACTLY like mine... !!!!!!!
I never even thought of static!!!.. I use a micro fiber towel as well.. Hmmm.. But it doesn't happen when I am wiping things down.. It only occurred 4 times.. And it was always right when I turned the vehicle on. No extreme weather so that was not the cause as you said. It would fade each time in about 5 minutes and would appear completely normal after that..
I took photo's and then brought the photo's to my dealer.. They replaced the entire ODO meter within my dash... TWICE.... They said they have never seen a problem like this.. They called Toyota for the second replacement to see if there were any other options.. I said it was pretty odd that the same exact brand new part was bad.. no!??!... So they replaced it again.. They still have no clue and either does Toyota... Keep us up to date if you get anywhere with any of this. For the time being, if you bring the photo's to the dealer, they will replace the part. They have to special order it from the manufacturer and it takes 3 - 7 days typically. Took them about 20 minutes to do the swap out the first time, the second time they wanted to keep it longer to test the connections further, etc so they ended up giving me a loaner for the day..
