Thank you Seiki. I don't know how to post a file or i would post it (the firmware from 1/9/2015).
As far as the remote control problem, that still persists (see above).
Ah darn, the one guy that managed to get a newer 2015 firmware from Seiki didn't know how to share it for anyone... Well, I'll email him, see if he's around to try to get it... I also sent an email to Seiki asking for the latest firmware, so we'll see if I can get anything from them doubtful as that is.
My fix on the blanking problem: I did cause this when I learned how to overclock my video card with the Custom Resolution Utility to output 1080p at a glorious 120 Hz instead of 60 Hz... This TV/monitor is beautiful once you can get it to 120 Hz, that's for sure!!!
So, here's what I did wrong: In trying to create a custom resolution/refresh profile for my Radeon 5450 video card using ToastyX's CRU 1.2.6, I selected the first option under Timing which was "LCD standard." However, this was not ideal with the Seiki 39" and would occasionally cause blanking regardless of the firmware I later realized...
The fix: I edited the profile and tried the 2nd option "LCD Native" which defaults to a perfect/even 120.000 Hz (instead of 120.003 Hz) for the vertical refresh rate, and 135.000 kHz, etc. In the end, the profile should be listed as "1920x1080 @ 120.000 Hz (297.00 Mhz)" - you want even values, no fractions, e.g. 120.003, etc.!
So, if you're having this problem and you created your own profile to force the option of 1080p @ 120 Hz, you might try checking that profile again.
I would've post screenshots, but this is my 1st forum post so I can't. But yeah, that's how I fixed my blanking problem, the settings for the custom creation of a new resolution were not quite right... Don't blame the TV just yet or the HDMI wire, although you'd want a quality, heavy gauged cable and not the el cheapos to rule the connection out. I changed firmware multiple times before having another look and realizing it was something as simple as this!
