Re: Element ELCHW402 - Will not turn on!
I have this same TV and I am a certified Industrial Electronics Technician, I went through all the normal troubleshooting procedures and came to the conclusion the main board has failed so I replaced it now the red standby light isn't coming on, and I have no voltages on any of the connectors. I have mains coming up to the contacts of the relay but the relay is not closing. I have tested most of the components in the main board and they all check out fine. Any ideas of where to go now? I originally had the same issue as the first poster, had the 4.5v on the 5vs and 5v-s, roughly 2 on the STB pin and nothing on the others. I checked the big 1000v blue cap and its reading 47nF which is fine.
