I have a Samsung tv that has the LED strips on the side of the tv frame. There are 2 strips per side, each strip has a 4 wire plug. How do you or can you test these strips with a standard LED tester.

Re: Testing side panel led strips
Look the power supply where the led connector is. Look for + and - and look for voltages that are all the same. If any are lower or higher you have a short. -
Re: Testing side panel led strips
looks like half the LEDs are out on each of the 4 strips.Comment

Failure Symptom
No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.
Where is the short?
Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.
Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but... -
I have 2: 75UK6190 units. One has a broken panel - it lights up and shows a bit of graphics. The other LG tv lights up but has no video. Turns on/off ok, and I swapped all the boards to check them all. I exposed the strips on the bottom of both panels. I tested the caps along the LED strips on the bottom of the panel. About 12 smd cap chips on the tv with no video, test shorted. I talked to LG tech support but they do not repair to this level, they just replace the panel. Now, there is a Philips mainboard that a smd capacitor chip shorts and causes a squeal from the power supply, and the fix is... -
Hello, my Aunt recently gave me her broken Sony XBR-65A8G OLED after getting a replacement. It had a 4x led flash error, a replacement T-con didn't fix the error but with helpful info from this forum I found one of the smd ceramic caps on the panel pcb (C575/C378) on a 24v line was shorted to ground. I removed that cap and the tv turned on without error. It still had a black screen with the original t-con back in it, once I put the replacement t-con in it finally had a picture. After doing a panel refresh it had a very good picture but with a few vertical lines for some scenes. For owners with... -
I had a the above tv qn55q60r that had a bad panel but everything else good. I had another panel here from un55nu6900 with bad leds and melted diffusers.
I put the nu6900 panel in and powered it up and it does work but there are lines vertical lines.
I was trying to change the panel type in the service menu but donβt see my exact panel. Anyway to fix this or someone have similar experience.
the clear picture is the panel type from the service menus on the nu6900. The other 1 is the panel type that was set for the q60r with the bad panel....01-13-2024, 01:57 PM -
Ok.. this is the story:
Have an old Samsung LED 3D TV (UE55F6475). First it started to lose light on the lower 40% of the screen now and then. Like for 10-60 mins and then it would work again. Then a bit later it just got stuck in that position. The lower 40% of the screen is dark, and it gets progressively darker the lower u go so it's obviously that LED strips where not working. I also looked for similar errors online and saw an exact copy and on that one it was faulty LED strips.
This is kinda how it looked, just that mine were at the bottom of the screen:
