Normally, the cost of the replacement and service of a cracked screen for a 40 inch LED flat-screen TV of any brand is $380 – can absolutely buy you a brand new television already!

@sigurdur The led strips caused the problem. At the end the tv was fixed by a professional workshop because after I replaced the power supply, T-CON board, checked all the wires and solder joints, it still didn't work. It makes sense since every function worked properly, only stips could have caused it.
Samsung UN43NU6950FXZA 43" 4K Ultra HD Smart LED Television. Essentially, the backlight is on but there's no picture on the whole screen. The red power indicator is on, and I've tried unplugging it for 60 secs, but it's stuck on a black screen. Also, before this happened, it was taking longer and longer for the tv to turn on.
This can help you isolate whether the problem is with the TV or the device. LED Backlight Problem: Sometimes the LED backlights can fail, which can cause the picture to blink or flicker. This would likely require professional repair. Power Supply Issues: Problems with the power supply or the mainboard can cause flickering issues.
Second, keep your monitor clean. Dust and dirt can accumulate on the backlight and cause it to break. Use a soft cloth or a gentle cleaning solution to clean your monitor regularly. Third, don’t expose your monitor to direct sunlight or other sources of bright light.

Backlight Bleeding Q70T 55". 13-10-2020 08:48 PM - last edited 22-10-2020 11:01 AM. I just bought Q70T 55" and I've noticed some pretty heavy backlight bleed from each corner of the screen, it makes watching movies with dark scenes unbearable. I have 30 days to return the item, but I'm afraid that the company I bought it from will say this
The LED backlight driver circuit is located in the power supply board. Next, I powered up the boards and checked on the DC output of the LED backlight driver and found it was only 31.8 volt DC! From experience, for a 32″ LED TV the dc supply voltage should be higher. In other words, the bigger the size of LED TVs, the higher would be the DC
