Hello, Own 50" DLP from 2005. I replaced the color wheel and after going into the service menu to change the index delay shut the TV down. When I powered it back up HMDI was giving me the no signal screen, but I still had audio.Tried multi devices to verify that it was the TV. I was then in the service mode yesterday, which has been about a month since lossing HMDI and then once I powered it back up I lost Component 1?????? Any ideas?
