Screen black I have sound

@cjc1940 , Carol , This is ifixit volunteer site, where we try to answer questions for persons to try and repair their devices them selves. We do not do repairs here. If in need of repair for your TV, I suggest you contact a good local TV repair shop, have them take a look and estimate repair. You could unplug TV and all devices, wait 20 min's, power up TV and see if it works and if it does plug in devices one at a time to see if it is a device causing issue. The link below shows how to trouble shoot your TV. Good luck.

I hope this helped you out, if so let me know by pressing the helpful button.
