To setup so a firestick could control my Mastertech tv when I tried element from the brands to choose from it worked like a charm for on/off control, volume and mute controls from the firestick. So you might try using Element as a brand or the codes for Element tv's. BTW, I went through several brands before I landed on Element which worked.

Hello ! It sounds like you are experiencing some issues with your TCL TV. It's great that the backlight lights are working fine. The blinking *********** light and white screen definitely indicate a problem.
One possible issue could be with the internal circuitry or the display panel itself. It's best to contact TCL support or a professional technician to diagnose and fix the problem. In the meantime, you can try power cycling the TV by unplugging it for a few minutes and then plugging it back in.
As for uploading a video, you can try connecting your device to a computer and transferring the video file that way. Alternatively, you can upload the video to a platform like YouTube and share the link for others to view. I hope this helps!

Unlock procedure and to override the password lock to many popular brand TVs are given.
Question edited for clarity and add CAPS.
To update the software, it has to be connected to the Internet, and it sounds like there is no internet connection via the television, so it is looking for a USB Cable to a computer.

Potential causes and solutions:
High Contrast Mode:
Some TVs have a high contrast mode that can inadvertently cause the picture to appear negative or distorted.
Try this: Hold down the volume button on your Samsung TV remote and navigate to the settings related to contrast. Turn off the high contrast mode, and see if that resolves the issue.
HDMI Connection Issues:
A loose or faulty HDMI connection between your TV and an external device (such as a cable box, gaming console, or streaming device) can lead to color abnormalities.
Check the HDMI cable for damage and ensure it is securely plugged in. If necessary, try a different HDMI cable.
Additionally, an HDMI handshake failure during setup can cause color problems. Restarting both the TV and the connected device might help.
Picture Mode Settings:
Sometimes, the picture mode on your TV affects color accuracy. Modes like "Vivid" or "Dynamic" may exaggerate colors.
Switch to a more standard mode like "Standard" or "Cinema" to see if the pink tint disappears.
T-Con Board Issues (Specific to Some TVs):
If you have a Samsung TV, a polluted T-Con flat cable could be the culprit.
To address this, clean the contacts on the T-Con board using isopropyl alcohol. First, remove any dust. If unsure, consider seeking professional assistance
Unfortunately you will have to purchase a remote control for it. All menu systems are within the setup display, all of which are controlled with the remote.They may be available on eBay.Andrew found the link.
