Vidao TV code for 40V40UHD

I have the Vidao 40V40UHD.  After a very long search I was able to Roku remote to work.  Haier, Sony, and Emerson did not work.  Vidao is owned by SIBrands.  Just from luck I found that the code ATVIO worked on the 2nd code.  Very happy now.  TV works great with my Roku now.
