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.
It indicates that the TV is not receiving enough power to operate normally.
The power cord or outlet might be faulty or loose. Try plugging the TV into a different outlet or using a different power cord. Make sure the cord is firmly connected to the TV and the outlet.
The TV might have a blown fuse or capacitor. This would require opening the TV and replacing the damaged component. This is a risky and complicated procedure that should only be done by a qualified technician. Do not attempt to do this yourself unless you have the necessary skills and tools.
The TV might have a software glitch. Try resetting the TV to its factory settings by following these steps:
Turn off the TV and unplug it from the power source.
Press and hold the power button on the TV for 10 seconds.
Plug the TV back in and turn it on.
If the TV shows a menu, select the option to restore factory settings. If the TV does not show a menu, repeat steps 1-3 until it does.
