Samsung Model UN58TU690TF Issues

[vortalexfan]

Hello everyone, a friend just brought over a Samsung 4K Smart TV that is giving him some troubles and I was going to see if I could fix it for him, The LED Light flashes twice and, and the TV clearly shows signs of it trying to power on but then it just shuts down and then it tries to power on again and then it shuts down again, also the remote is not outputting an IR Signal from what I can see with the camera on my phone and I've tried 4 pairs of known good AAA batteries in the remote, and I wonder if maybe the remote not working might have something to do with the TV not wanting to power on?

Any ideas?

Thanks for your help with this issue.
