Hello carp girl, This may denote a proble in either your switching powers supply or your Horizontal section derived high voltage power supply. These are both very dangerous sections in your television. My next question is important; do you have a background in electronics? If not I would not advise you working on this problem yourself and that you take the TV to a repair shop for servicing. If you do have some background in electronics, I would like for you to make the following obeservations: Is the set newly purchased or refurbished/old? What was happening prior to the set going out? Are there any sounds coming from the set when you turn it on "like clicking or buzzing"? Has the set been dropped or had fallen in any way off of what it was sitting on? Was the set plugged in during a storm? These are some questions to develop some background into what may have happened which lead up to the trouble you are reporting. Thank you, Shuttle83

bro you should take it to the repairer,No other options you have. it can't be fixed by doing anything accept changing it's screen or repairing it, if it's possible

Hello. You can check HDMI cable in this case. If you're using an HDMI port that's not working well or has been damaged, it could result in a darker-than-usual screen. If you switch the cable or change devices and the TV is at a regular brightness, this is the case.

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.

All I can advise is to take it to an authorised Samsung repair shop. A list is available on the Samsung web site.

The old yellow, red, white RCA cables are analogue signals, while HDMI cables only carry data. They are in no way compatible. You can buy active conversion boxes that will convert analog to digital, but simple cables cannot work

It can't be done. The Samsung remote will be single frequency for that Samsung device only and the LG remote for that television (or series) only. Companies don't make cross-control between makers easy. The only exception is cable and satellite boxes to allow their remote to also control the television. If you have lost a remote or it doesn't work, this is the answer https://www.fixya.com/support/r29872378-universal_remotes_no_facsimile_remote ..

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.

Can you tell this power supply board zener doide value?

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:

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
