One minute it was working fine with both PS3 and Sky HD box plugged into to two different HDMI ports, the next it wasn't. I left my daughter in the lounge so she may have pressed something, but she promises that she didn't. Now the TV just says no signal. I have tried all the usual turning it off and on a gain, swapping HDMI ports on the TV, I even tried to plug my laptop into the thrid port, but the TV still did not recognize this. I have also just connected my TV to the web and updated the software, but it still doesn't recognize anything. Any help would be greatly appreciated as I can't afford a new TV.
