There are long skinny light tubes behind the screen that use high voltage to operate. What you are seeing is what it looks like right before they fail. They can be replaced, but it is a big job.

There is three possibilities:
1. Defective back lights LED strip.
2. Defective LED driver section integrated in the main power supply.
3. the main board.

How to check it:
1. You need a LED back lights tester to check the strips, or open the panel, use a 3.7 V DC power supply to test each LED diode separately.
2. Use a multi meter to test the out put DC voltage from the connector to the LED strip between the + & - for each section, (like 1+/1-, 2+/2- etc.) it should read 140 - 220 V DC. (need power up the TV).
3. Un-plug the cable between the main board & the power supply, power up the TV, if you get the back lights light up, the main board is bad.

Try these codes. If you wish to get more details; check the sites linked here. It has set-up code list & set-up procedure to many popular brand remote controls. Common set-up codes to check with TVs and other devices are given, in the order of the "device's brand name list" in alphabetical order. Pull up older posts.

Programming Notes
• If your device does not respond to the remote after trying all codes listed or your brand is not listed in the code list, use the Auto Code Search method to program your remote.
• Sometimes the first code that "works" with your device may operate only a few functions of your device. There may be another code in the code list that performs more functions. Try other codes from the code list for more functionality.

This is a trial and error procedure; and quiet time consuming. You might have to check different codes said for your device.
Search the site by type in the "brand name" of your device; that you want set-up code, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

What's your objective?

I have the same issue, you've got to disassemble it and fix the connector that's on the front right side when looking straight down at the blu ray player, it's goes from the main board to the round selector on top that allows you to control the machine!

It would be best to contact the manufacturer or TV repair facility. This is a car forum and we wouldn't have the right info.

Sounds like what my flatscreen did. What i found it to be when i removed the back is, capacitors had failed in the main board. Only spend 12 dollars on capacitors, hardest part was soldering them in.
