The fact that the backlight stayed on when you unplugged the cable running from the power supply board to the main board does suggest that the issue is likely with the power supply board. However, it is still possible that the problem could be caused by a malfunctioning main board or another component of the television.
To confirm the cause of the issue, you may want to try swapping out the power supply board with a known good one to see if this resolves the problem. If the issue persists even with a new power supply board, it is possible that the main board or another component of the television is the cause of the problem.
If you are unable to troubleshoot the issue using the steps above, or if you are not comfortable working with electronic components, it is recommended to seek the assistance of a qualified technician to diagnose and repair the television.
Hello, that set uses 2 LED strips that are no longer available and the 55" strips are physically too large to work, the panel from Samsung is no longer available, but some list it as "available -special order" but it's no longer available so how are they going to get it?. But to make sure they are bad, unplug the main board from the power supply and plug the tv back in, if they light, the main board is bad. If they don't make sure the voltage is there to operate them, if not the power supply is bad. Parts for a 10 year old tv are getting harder to find. panel part number is: BN07-01170A Techman 57

There could be a bad connection or a processing problem. Unplug the video cables and another devices and things that are attached to your TV for about a few minutes and see if the lines are not there any more and if the lines still show up on your TV's screen then you need new cables. Or there could be a problem with the TV's screen or the T conn board then.
Hi,
you can start by looking for a speaker adapter on amazon. To ensure compatibility with your samsung tv, you can provide the specific model number to the seller so that they can check on their end. And you can also call the manufacturer of the product to ask them to verify the compatibility with your tv as well.
Thank you.
Here are some general steps you can try to program your remote control:
Determine the brand and model of your remote control. This information should be available in the user manual or on the manufacturer's website.
Turn on your Samsung TV.
Press and hold the "Code Search" button on your remote control until the indicator light turns on.
Press the "TV" button on your remote control.
Enter the code for your Samsung TV. You can find a list of remote control codes in the user manual or on the manufacturer's website. Alternatively, you can try entering codes until you find one that works.
Press the "Power" button on your remote control. If the TV turns off, the code has been programmed successfully. If the TV does not turn off, repeat steps 3-5 with a different code.
If none of the codes work, it is possible that your remote control is not compatible with your Samsung TV. In this case, you may need to purchase a new remote control or contact Samsung customer support for further assistance.
Remove the ribbon connectors going from the tcon to panel boards, power the set up and see if it stays on then, you won't have a picture naturally but see if the backlights and sound stay on.
Hi,
Please ensure that you're using the correct input on your samsung tv so that you're able to access your channels properly. If this is the case, then you can power cycle your tv (ie unplug for 30 seconds to 1 minute). If this fails, please remove all accessories attached to the tv and try again. Otherwise, you'll need to factory reset the tv before moving forward with a potential home repair schedule via a company like Geeksquad/Bestbuy.
Thank you.
Hi,
Try switching tv inputs and checking if the black lines remain. Please remove any tv accessories (ie video game console, dvd player) .
If this does not work, please power cycle your tv. Otherwise, I would recommend using a tv repair service vs attempting to fix the tv with spare parts.
Thank you.
Samsung sets with NU as the 2nd set of numbers were notorious for panel issues, sad as it sounds it may be time for a new set unless it's under warranty
Hi,
Please flip through a few channels and double check your brightness and/or display settings. Please update your tv firmware and check that energy-saving mode is turned off.
Thank you.
You have multiple issues. The origin of such has several possible causes. You can try to address and elimnate some of these and possibly arrive at a fix yourself. 1) There may be a problem with an accesory. Unplug such and restart the TV. 2) There may be a problem with a surge protector. Try plugging the unit into the wall directly. 3) There may be a problem with the internal power supply. Unplug the TV for 30 seconds and then plug it back in. It the power light ceases to blink, you may be okay. 4) Disable the energy saving mode. 5) Set the backlight to minimum. 6) And very possible due to your audio problem, your batteries in your TV stick may be weak and need replacing. 7) If a HDMI cable is attached, it may need reconnecting or replacing. 8) You may have to replace the TV if there is a further techinical issue.
On Samsung TV's with 2 blink of the standby lamp it will never be a main board issue, this code means the B+ regulator has sensed over current and shut the supply down as a safety precaution. Chances are your LED backlights are bad, several are shorted causing excess current draw, unhook the plug going to the backlights, power the set on and see if the code goes away, the set should power on, naturally you won't see a picture but would have sound if you selected the correct input.
It's possible you received a defective replacement board, as said before we don't sell parts, just give advice on how to repair the TV. Where did you purchase the boards? If ebay chances are you received a bad board
