Could be the ysus board or faulty panel if u are technical minded then open it up after it has been off for at least an hour and unplug the upper and lower board on the left and turn it on and if the screen lights up then u know it is the ysus please let me know and be very carefull if it looks too hard take it to a dealer

Playstation 3 console not displaying on tv screen


Make sure all the video cable connections are plugged firmly into the back of the PS3
The sound you are hearing indicates that you are on the right track. To get the video to work you will need to select the correct channel on your TV set. Connect the video cables (yellow) to the video INPUT of the AV port of your TV and then change to the AV channel on your TV set to view the picture.

Please let me know if this did not fix your problem
Cheers

Zenith tv


well 2 things come to mind, 1st go into menu and run channel scan, see if that brings them back

2nd if you see a black square on the screen of these channels turn off the closed caption, again in the menu

and if all else fails hook up cable or sat box from the video out to the video in on the tv, set the tv to video input viva remote or going to channel 00

hope this is of some help
