Sounds as though you have a leaking Capacitor in the horizontal section. The problem capacitor is likey to be orage in color and rated at 2kv or higher. Located next to the High Voltage transformer ( Flyback transformer ). Be very cautious if you are changing this, or any part yourself as the picture tube can charge high voltage ( up to 35,000 volts ) for a long period of time. Always discharge the picture tube first before servicing a set.
Replace the capacitor with a like part with the same or higher voltage rating and the same capacitance number ( mfd, pfc,or such ) as listed on the side of the part.
Good Luck

Hi Chandra,
The price on this product looks like a bargain to me. Although you have noticed many problems from users on this set, you will see problems on any set, so I would doubt the problems you are seeing are of a quanity that should not be of any concerns.
Good luck on your purchase.

well what sounds like happened is you blew up the tube in it. have you unplugged it from the wall and just let it sit some times that helps because what will happen is there will be a Electrical build up and it won't work right. an other thing you might want to do is hit the Degauss button on the remote. plug some sort of video signal into it and go through the inputs to see if that helps, mine did that every thing would just be black but i plug in my video camera it would detect it and make sure that the audio cables are plugged in these TV might just be that old that they have to have both audio and video in order to work.

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.
