There are several flavors of screen flickering/shaking being reported. Customers
who exchange their SP4's report that the exchanged refurbs start flickering as
well.
If you have flickering/shaking when you boot to the UEFI, this is a hardware
issue. Wait until your SP4 is flickering if it doesn't do it constantly and then
access the UEFI to verify:
The UEFI settings can be adjusted only during system startup. To load the UEFI
firmware settings menu:
- Shut down your Surface.
- Press and hold the volume-up button on your Surface and at the same
time, press and release the power button.
- When you see the Surface logo, release the volume-up button.
The UEFI menu will display within a few seconds.
If no issue in the UEFI, there is one flavor that MAY have a work around but it
may not work for your case.
- take a look at Hal's fix and see if this works for you.
Microsoft really doesn't have a solution for this - but if the fix to show
seconds works, recommend you don't even consider an exchange (which is what
Microsoft recommends to folks that call support) unless the issue returns. Your
original one year warranty is most likely up and it will cost you $$ to
exchange. (But if you ARE under warranty, you COULD exchange your SP4.)
There have been over 1000 people complaining about flickering issues. The trade
press has picked it up again last month. If you do a search, you will see what
the press is saying. Here is the search to run:
Microsoft outsourced agents are telling customers to reimage and jump through
all kinds of hoops. No one has reported that reimaging resolves the issue. If
you are in the US, you can try going to a physical retail Microsoft Store and
asking to see the manager to see if they will swap you out, even out of warranty
at no charge, or better, swap you for a newer Surface Pro 2017 (for an
upcharge).
I know this isn't good news. I've been trying to get Microsoft to say more than
"we are aware of the issue" for over 6 months without success. It's obviously an
issue that Microsoft doesn't want to really talk about (I don't work for
Microsoft).
