Was watching TV and all of a sudden, no picture, blue screen and box that says "No Signal or Weak Signal". Still had sound because I use an optical cord to my amplifier. After trouble shooting my other devices, none of them worked in the HDMI cable connection (PS3 and blue ray player). I was able to view the blue ray player's welcome screen to come on the TV for about 5 seconds then it goes back to the blue screen. It does this each time I turn on and off the blue ray player. I also noticed, when there is a HDMI cable connected to the TV, the box reads "No Signal or Weak signal", when I remove the cable it reads, "Check Connection". Seems like the TV knows there is a cable connected but It seems to me there is an issue with the internal components of the HDMI connection. If anyone can help me it would be greatly appreciated.
