Samsung Tu8000 fails to power on with no screen visible.
It's been three years since we bought this TV. We changed the screen once during warranty because of lines, and two years later it began looping. A quick web search suggested covering a few pins on the display connector after confirming the main board was okay. Even without the connector, the issue persisted—removing it didn’t stop the loop. After that, the TV worked normally, with no looping, constant backlight, and I can connect my phone via Bluetooth and play audio through the speakers. But there’s still no display showing anything. Have you tried covering different pins? It seems the problem might be fixed once the backlight is disconnected completely. Upgrading the pins didn’t help either—only the backlight remained visible without content.
The nearby store dismissed the idea of fixing it, saying it’s pointless. Through my own investigation and testing, I believe the issue lies with the panel itself—not any internal board problem.
I felt the same—swapping the whole TV would be better than using this dead monitor, and selling its parts could bring in some quick cash.
We just spent all our budget on a TV for this unreliable gadget that failed twice over three years (it was covered under warranty once—there were black lines on the screen). No one wants to repair it, and it’s now just scrap. Maybe it could be turned into a basic soundbar since the speakers work via Bluetooth after fixing the tape. We own a Mi TV 4A for about 110 USD, and it still functions after four years—definitely worth the investment compared to this broken unit, which cost around 1100 USD. It’s odd how a big brand like Samsung could ruin two entire budget TV lines, especially since they sold those models for two years. Every TU7000 and TU8000 (the top-selling Budget 4K TVs in our area) is experiencing the same problem.
