Samsung TU8000, backlight and sound on, stuck in blue screen

[mar1in]

Hi everyone,

I've got this Samsung here that would be stuck in a boot loop.
After opening up and doing the tape block method, I was able to get it to turn on and play sound from the HDMI input, but with a blue screen.

Does that mean there is another combination of pins that I need to block in order to get a picture, or is there something more serious, faulty mainboard or faulty panel?

Thanks in advance

Panel

Try these. A member here named Lotas posted it some time ago and it worked. Got great picture on half a screen. Was definitely a bad panel.

Bootloop for Samsung usually means panel. With tape method, try more pins or less pins. If it stops the bootloop you are probably in the area. But generally not fixable. Can check the caps on the buffer boards for shorts and maybe get lucky. Also there are some tricks I've seen on here maybe someone can lead you to one that had potentially fixed this issue
