I find the contrast and readability of the scope to be fine.
Someone mentioned the colors from the Chinese flag played a role in the selection...
It was my joke.... but who knows...chinese like red and yellow.

.... and yet they don´t use those colors in the splash screen at boot-up.
Dear Mr. rf-loop:
I have been reading this thread for the last few days (I´m not done yet) and:
1. I want to congratulate You for your deep insight and extremely valuable contributions to this thread.
2. Since You are a senior member of this forum, I wonder if You can contact "tinhead" and ask him to give us a hand. I believe he is the most qualified expert on OWON´s firmware.
Yours faithfully, (Ystävällisin terveisin,)

HOW can I "point him to a post" Forgive me please.... - never been in a forum before
A couple of quick notes on the SDS7102(V) and current software/firmware for it.
For the software, I went to the PC Software tab on the OWON update site (http://www.owon.com.hk/service_s.asp) and as of this writing it says that 2.0.8.24 is the latest PC software release... but the link to that software is dead! Thinking maybe the uploads were more up-to-date than the text of the page I tried a few other iterations, and found that there *is* a OWON_Oscilloscope_2.0.8.26_Setup.rar there. I downloaded it, ran it through a few AV scanners to be extra cautious, and installed it. It seems to work and the "About" box says it's "Version 2.0.8.26 (build 20141228)". YMMV of course.
For the firmware, I went to the Firmware tab, entered my serial (be sure to omit the last three digits or you'll be told incorrectly that "The firmware onto your OWON device is in latest version, no need to upgrade, thanks") and downloaded "sds_upgrade_3.2_3.3_3.4.rar". I installed it and now I'm up to version 3.8 on the scope. As usual it started with Chinese menus so I did the "Utility -> H2 -> English" maneuver to change it to English, and that worked fine... until I rebooted the scope and saw that it was right back to Chinese! Tried changing it again, power cycled and back to Chinese! Hmm.
For grins I power cycled, changed the language to English and then set the clock to something other than the default. *That* apparently helped make the setting stick, and it's been on English ever since.
tl;dr - After updating to this firmware, update the language *and* set the clock... it doesn't seem to stick otherwise.
Thanks for the info!
I just downloaded OWON_Oscilloscope_2.0.8.26_Setup.rar using your tip! As you implied, all I had to do is change the 24 to 26 on the address bar of the screen with the Oops! message.
A couple days ago I also downloaded the firmware because it had a later date than my current version, but after installing it I still had version 3.8 on my scope. However, I didn't run into the problem of it reverting back to Chinese.
Has anyone come across this fault.
The oscilloscope powers with up green light and fan runs but no display.
I checked the voltages at the pins there are voltages at the J3 connector pin (5 and 6) 8.4V pin 4 seems slightly high 7.84V instead of 7.6V A.C trigger 1.435V. GLED 11.75V RLED 0.5mV. There is a bulging capacitor on the board C4 not sure how much difference or how this will effect the board it has 8.4V across it. But is showing some ripple.
is anyone able to compare the voltages or help with this.
Thanks

Fixed I replaced the capacitor 1000uf 16V on the power supply board for a 15V 1000uf i salvaged from an old free view set top switch mode power supply board. The oscilloscope switches on. Thanks again TomC.
