Well on the Tv itself the vol up and vol down and the channel up and down will help you do this there may even be a menu key which is a nice feature but if not try pushing both the up and down vol or the up and down channel buttons at the same time. if not that try pushing different combinations you get it don't let that electronic win....lol

Hello!

You should check first if the IR sensor (Infrared sensor) of your TV is still working. It is beside the pilot lamp to where you point the remote to control your TV.

Use the camera of your phone or your digicam to check if IR sensor is still working.

Looking on the IR sensor of your TV via the camera of your phone or digicam, if the IR sensor is working you should see it illuminates. If not, then IR sensor or its sensor board is deffective.

The best way to fix it is to bring it to a certified technician to replace the whole IR sensor board.

Good Luck!

Hi cewilso,
Make sure that you have a good connection from your cable box. If the static lines didn't appear in Video mode then the problem is in the reception. Hook up properly the cable connection and ensure a good source of signal from your cable provider.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

unhook 1 tv at a time leaving 2 tvs each time hooked up. try every combanation Possable to see if it's a tv problem or if when you have all 3 tvs hooked it makes the signal weak. this can happen cable guys say no but it can been there done that. if 2 works and 1 dont in every combanation the problem is in the cable system. most cable guys check the signal outside. with the splitter block unhooked. this gives a false reading.
