Red lines and strong red tint to picture
By placing your hand over the red lens you stop it's convergence with the other two colors by stopping it's light emmission. That tells you two things, (1) convergence of the red tube is way off; (2) it hasn't yet placed any load on the 20+/- supply line or the unit would be in shutdown.
You'll need to have the convergence amps replaced though. ICz103 and ICz104 are a Samsung p/n#BP13-00006A or the more common equivlent Sanyo STK394-250 and you'll need two of those.
Good idea to test and replace any of the feed resistors that may have changed in value also.
If any of this sounds complicated take it to a reputable shop. Most shops may have the parts on-hand and it's not too expensive a repair.
With the above info you'll at least be on some higher ground with the repair shops you call to see if they have the parts and how much they generally charge for convergence repair for your model.
Good Luck

Samsung 55 TV White vertical patches?
It sounds like you might be dealing with backlight bleeding or an issue with the LED backlighting in your TV. This can sometimes occur over time due to normal wear and tear or manufacturing defects. If it started as a faint single brighter section and has now expanded to four, it's likely a hardware issue. While it may not be an easy fix, contacting the manufacturer's customer support or a professional technician would be a good next step to diagnose and possibly repair the problem. If you'd like, you can share the pictures for a more accurate assessment.

Samsung un55nu6950fxza TV
These LEDs are very susceptible to static electricity damage. What happens when they get zapped is a tiny threading fault starts in the LED crystal. The aluminum contact metal starts migrating into the crack, makes it wider and longer, and eventually goes all the way through the LED and shorts it out. When that happens, the metal overheats and burns out the LED so the entire string goes dead.
What this means for you is that the original LED may have been may have been zapped at the factory. The replacement strip likewise, or when it was removed from another TV (if it is a used part), or when you put it in. It should have been in anti-static packaging. You have to be very careful not to touch any of the circuitry on the LED strip, and make sure you ground your hand to the TV metal both before picking up the LED strip and right before connecting the strip to the TV. Better yet, use an anti-static wristband connected to the TV frame.
It is possible that the LED driver for that string is pushing too much current, but that's not likely. You would probably notice that part of the screen is unnaturally bright.

Brand new Samsung 77 OLED tv. Got knocked off the stand and fell on and bent the lower corner
It sounds like your TV has a display issue, likely caused by physical damage to the screen due to the bend. Repairing a damaged screen can be quite expensive, often nearing or exceeding the cost of a new TV, especially for larger screens like the one you described.
Here are a few options you might consider:
- Sell it as is: You can try selling the TV in its current condition, clearly describing the issue with the display. Some buyers may be interested in purchasing it for parts or attempting a repair themselves.
- Attempt a DIY repair: Depending on your technical skills and willingness to take on the challenge, you could try to repair the TV yourself. However, this can be risky and may void any remaining warranty. There are online tutorials and replacement parts available, but again, this route requires some technical expertise.
- Professional repair: You could contact a professional TV repair service to get an estimate for repairing the screen. Be sure to weigh the cost of repair against the potential selling price of the TV after it's fixed to determine if it's worth the investment.
- Sell for parts: If repairing the screen is not feasible, you could dismantle the TV and sell its components individually. Some parts, like the internal circuitry or casing, may still hold value to electronics enthusiasts or repair professionals.
- Trade-in or recycle: Some retailers offer trade-in programs where you can exchange your old electronics for store credit or discounts on new purchases. If the TV is beyond repair, you can also look into recycling options to properly dispose of it.
Ultimately, the best option for you will depend on the extent of the damage, your budget, and your willingness to invest time and effort into repairing or selling the TV.
