Hisense K3300UW - Flashing RGB Colours

[Slayer7744]

Hi There,

I'm pretty desperate to fix my TV considering it's only been a couple months since I purchased it.

I updated its firmware and it was stuck in split screen mode (similar to 3D side-by-side) and I couldn't bring it back to one screen so I factory reset the TV and now it's stuck flashing White, Red, Green, Blue over and over.

I've tried the up/down and left/right power off trick to no avail. Holding EXIT also does nothing.

It's exactly like this video: https://www.youtube.com/watch?v=cbfvKFlCXLg
