Hi Tom Sorry to hear about your Lemon. I learned about Samdung products awhile back. I refuse to buy any of their products because of their bad attitude. The Non Innovators who reverse engineer to get ahead in the market & program devices to work super fast on benchmark tests. A bit like FolksWagon did with falsifying dynamometer results for EPA readings. I know all businesses can make mistakes and make poor choices. But, we really shouldn't support companies that blatantly falsify to get better market share. All electronic devices (inc HD TV's) have problems with Electrolytic Capacitors fizzing out. It's a huge problem. But I'm sure "some" companies buy underrated parts to insure they don't last too many years. Go with respected companies like Sony, Panasonic, Hitachi etc. and check the following before buying. Warranty period -(Nice if you can get 5yr like my Mitsubishi Electric Fridge) User interface - The on screen controls. Ease of Use. Input Ports - USB, HDMI etc The video codec's that are supported. eg .avi, .MP4 etc the more the better. (Look how many codec types VLC support) Plug a HD drive into the USB. What movies can it support? Cheers Samsung Smart TV surveillance prompts FTC complaint Ugh Samsung Rigged the Note 3 to Perform Better in Benchmark Tests Samsung Scandal

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.

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.

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 ..

It's a Samsung and has power supply issues. Repair/replace the power supply and that should get you going, if nothing else is damaged.

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.

Possibly, or dry joints, or failing Caps. Get your meters and oscilloscope out. ..

I would employ a Samsung registered engineer to repair the power supply. Seems like he knows nothing about Samsung capacitors.

That sounds like a pixel issue and a replacement CCD imager is the only cure. Probably too large, more than a few pixels out, to cancel it with software.

I suggest an authorised Samsung repair agent, (a list can be found on the Samsung web site), otherwise you will get panel changers and not engineers that repair to component level. One common culprit of this issue power supply issue, caused by a faulty power supply unit or the TV not receiving enough power, caused by faulty electrolytic capacitors on the Power Supply board.

Even if you choose to browse the selections on the Samsung site, check the specifications of the new DVR to ensure that it supports the same type of cameras and has the same number of channels as your current DVR. That information would most likely be in the hands of Samsung or the manufacturers of your cameras. I would check with their customer support. and/or a download of the user manual of the DVR of interest. Possibly someone at Best Buy might have access to compatibility information being a retailer of such. Some of the other popular brands that offer security DVRs include Hikvision, ZOSI, and Dahua.
