Bought a Sony nsx-40gt1 less than a month ago up until today I have been very pleased with my purchase. Today I came home from work and my wife said there was no longer any sound coming from the TV when using our cable box. Cable Box connected to TV via HDMI Cable = no sound Cable Box connected to TV via Component cables = works as normal PS3 connected to TV via HDMI cable = TV saying there are no inputs Things I've already done: 1. Reset TV to factory defaults 2. Did a power reset of the TV as it says on the Sony website, done this more than once leaving he TV completely unplugged for a while. 3. Swapped out various HDMI cables 4. Verified the PS3 is working correctly with an older LCD upstairs on HDMI mode 5. Tried all 4 HDMI ports on the TV with cable box and PS3 always with the same result 6. Checked the audio settings on my cable box twice to make sure the audio is going out to HDMI 7. Checked the Audio settings on the TV to make sure it was set to TV speaker and all that. I don't have any other HDMI devices to test with the TV but if the PS3 works on another TV via HDMI I'm thinking it has something to do with the HDMI stuff. I'm not sure what to do now or where my next step should be any suggestions at this point are welcome. Right now I have my boxes and stuff out because the only other thing I can think to do is take it to Best Buy and hope I can get another one.
