Plug your PS3 on either TV. Turn on the backswitch. When the red light in front is on, put your finger on the on/off button in front AND KEEP IT THERE. You will hear some beeps; don't worry about that. Keep your finger on the button until the front power light goes red again. This resets the PS3 video settings. Turn the PS3 on and the TV should pick up the signal.

Hope this helps. Keep us posted.

Hi - the tv sound will be picked up like an fm radio signal at 83 mhz. To get there, press the reset button the side of the headphones, then press scan. the first signal to be picked up will be the tv signal. This assumes, of course that you have fresh batteries in the transmitter and headphones, and that the volume is turned up on the headphones and the TV. Worked for me. The signal is not stereo, though.

Tries change another HDMI cable,reset all HDMI setting to reset factory setting.
