Hi I just bought a new tv, the JVC 28X4, from empire direct. When I switch it on sometimes the set turns completely on and other times it goes straight to standby and then I turn it on with the remote. I have no idea which is correct but am assuming this could be a problem as it surely should do one thing or the other consistently? Secondly, when the set switches on there is a very loud electrical "ping" noise. Again I'm not sure if this is a problem or not. It is a sound I could get used to but if it is a sign of something not working properly then I would rather get it fixed whilst inside the guarantee. Please help! thank you.
