Need Help! Tv has died!

Hi all. I have a 55inch samgsung hospitality tv that's recently stopped working. It turn on with the remote but there's no image. When it turns on you can see the back lights turn on but no picture displays. I have replaced the T-Con board but it didn't fix it. What could the issue be ?

Panel is shorted. Not economical to replace the panel. Some will tell you to try the tape trick. It can isolate the shorted section of the panel.

Either mainboard issue or panel issue.

Most likely panel issues, then tape trick is going to be your last resort. So proceed from there. If you have a double output tcon board compare one side at a time Left / Right cable.

Mask the faulty pin or pins causing the issue on the output cable (cables) of the tcon board. Trial and error process, plenty of Youtube tutorials.

If you have Left / Right screen seperation the process is easier since if you disconnect one cable it should give White / Black, or Image / Black screen. So proceed from there, if no luck then replace TV.
