Only SMARTVIERA appears on the screen, no pictures, no menus
Hi @jarann I found a link to the Panasonic TX P65VT50Y service manual but unfortunately it costs $4.95 to download and view. If you get this manual scroll to p.25 to view the no picture troubleshooting flowchart. I also found a link to similar series models but they are on a different chassis which hopefully may be helpful, although it may be different. Still worth a look though. To download this file click on the “I am not a robot” Captcha checkbox below the Document preview box and then click on Go to Download. When the sentence below the box changes from This file is downloadable free of charge (5/day): …processing… to This file is downloadable free of charge (5/day): Download (panasonic th-p65vt50 chassis gpf15d-a) click on Download. Be patient as it takes a little while to find the file. Here’s an image taken from the manual (not the one for your exact model) that shows the no picture troubleshooting flowchart.
