Re: LG 50PZ550 / Zenith Z50PV220 clicking not power on, troubleshot but not sure

Hi. I have almost the same problem with my Zenith z50pv220 tv. when I want to turn it on, just clinking and it goes bact to standby. No picture and sound it does not turn on. I bought a new z sustain and a new power supply but the problem is stayed. Somebody has any idea what can I do? Thank you
