Left side of the LED screen darker with outlines around images, re-setting does't help
It is best to contact the authorized service center for Hisense.

I'd say that's just the way they're made. The background light for the screen just doesn't illuminate evenly. If it's noticeable enough I'd try to get it replaced under warranty. This can also happen when the screen is pushed and it gets damaged, but if it's happened twice it's probably just the way they're manufactured.

You have a defective light engine and you do not have to be under warranty for Hitachi to replace this part. We just went through this and here's what you need to do. Call Hitachi's customer relations department at 800-654-7013 and tell them that you have a defective light engine. They will act like they've never heard of this problem but they have. They will give you the names of some certified dealers in your area to call. Once a tech comes out and confirms that it's the light engine, call Hitachi back and they will send a brand new light engine to the dealer and Hitachi will cover the cost of the part (cost $1500).
Here is the deal, if you're under warranty, Hitachi will cover the part and the install. If you're not under warranty, all you pay is the install. Our install cost $400. Others on this site have paid $200. Do not let anyone tell you that you have to pay for the light engine part...you do not. Hitachi has not recalled this part but they are replacing it for free. Also, deal only with Hitachi customer realations number that I listed. Good Luck!

SERVICE MODE WARNING:
Without proper documentation Don't mess around with the service mode adjustments unless you know what you're doing and have the service manual to guide you.
Once you enter service mode the first thing you should do is record all the original values BEFORE you change anything! - This is the only way to restore the television to its original (factory default) state should it become necessary to do so.
Then, bring up the cross-hatch pattern by repeated pressing of the TV/VIDEO button. You can then use the volume Up/Down buttons to change the PARA settings, this should cause the grid to bow in (concave) and out (convex). Adjust until the grid is the most linear.
The numbers 1,2,3,4,5,6 jump to different items. 9 displays SELF CHECK
The number 7 displays a grid. There's a blinking cursor in the upper left corner. The numbers 2,4,6,8 move the cursor. 3 cycles the colors (RGB), 5 stops the cursor from blinking, then when you push 2,4,6,8, you are adjusting the convergence at that point for the selected color. Pushing 7 again gives you a "warped" grid for a few moments. Pushing 7 again removes the grid from the screen.
If you're attempting to adjust color or geometry errors, you'll need the Video Essentials DVD, Laser Disc or some other source of test material.
