These units have the power supply and ballasts on one board, It's common for the capacitors on them to fail(bulge, leak, pop), those are the visual ques that they are bad, i've had good luck replacing the capacitors on this model to save them from the trash.
inspect C20, C21, C34, C37, and C36, they are all the largest caps on this board that the power cord plugs into.
More than likely, the planar LCD sets have a set of 5 1000uf 16volt caps that fail. There could be other problems, but to check, unplug, pop off the cover, and look at the brown cannisters. They will mostl likely be bulging, or you may see blackish goo coming out of them. They're fairly easy to replace if you have experience with a soldering iron.

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
