When I power my new pi 3B+, the red light turns on, but there is no flashing from the green light. To try to fix this, I downloaded the latest version of Raspbian, but it had no effect.
The pi worked initially, but after rebooting, it just gave me a blank screen and I couldn't connect via ssh. I tested the SD card on a different pi and it works fine.
Any thoughts?

Make sure you have the latest version of Raspbian on the SD card.
The RasPi line has gone through enough hardware revisions that "the card boots on another RasPi" no longer has much diagnostic value. It's bad enough that a card that works for a year-old Pi2 may not boot a Pi2 made in the last six months.

I downloaded the latest version of Raspbian on the SD card, but I am still having the same issue.
Edit: The other pi I mentioned I tested it on was a ZeroW bought at the same time, a week ago. I've got another 3B+ arriving tomorrow and will test the SD card on that.

What voltages do you see on the RasPi's 3V and 5V GPIO pins?

The 3V was 78mV and the 5V was 5.4V.

Re: Pi 3B+ doesn't start
Hmm.. what are you using as a power source? 5.4V is outside the expected range.

A plug going from wall power to microUSB. I tried a different power supply and got 5.35V.

Re: Pi 3B+ doesn't start
That’s still higher than normal, but could be part of a general power supply failure.
