50" Sharp Roku 4k TV completely unusable with PS4 (recurring problems since 9.3)

Earlier in the summer, after the 9.3 udate, I was having problems with my RokuTV shutting itself off, or restarting itself while using my PS4 for anything (gaming, streaming content, or even just being turned on).  I scoured the community, Reddit, and eventually e-mailed support.  They suggested simple fixes such as "plug the TV into its own outlet, turn it off, wait 15 seconds."  

For whatever reason, I stopped having the problem for about a month.

Then, over the last week, after literally changing NO settings, and simply continuing to use my PS4/TV as normal, I began to experience the problem again, but it's worse than before.  Now, the TV will shut itself off completely any time I use the PS4 for more than a few seconds.  

The TV has since begun shutting off when I'm doing ANYTHING.  This issue only began with 9.3.  Literally no amount of factory resets, settings changes, etc. have fixed this.

This is a 9.3 problem.  Scores of others have voiced similar problems all over various online forums.  This issue seems to be ignored, brushed under the rug, and treated very neglectfully.  I was EXTREMELY happy with this TV until this began around 9.3.

For the past couple weeks, I've noticed the TV hasn't been in clear "4k" quality. Everything is noticeably worse than 4k, most likely 1080p.

The Roku main menus, Netflix, YouTube, my ps4 pro all seem fuzzy, even though they claim to be outputting at 4k. There is no difference from 1080p and 4k on my ps4 pro.

I've noticed that when I turn on the TV, the sharp roku tv logo IS displayed in 4k. Then after a moment the screen goes black and it shows the logo again, except this time it's definitely not in 4k, (1080p probably).

I've power cycled, updated software, factory reset, but nothing appears to be working.

Model: LC-50LBU591

S/N: YN004V621495

DI: 9H4794621495

OS: 9.3.0 Build 4194-38

Tracker ID: 95-412-672

The issue happens across all channels, outputs, and menus. The picture is noticeably fuzzy, definitely not in 4k, most likely 1080p since changing my resolution of my ps4 from 4k to 1080p shows no difference.

Booting up the tv briefly shows the logo at 4k resolution, then goes black and shows the logo at 1080p
