Hello everyone,
I have aquired a Vizio Plasma that upon startup the screen flashes between an "Off" state to bright white. The power LED in front of the TV will stay green during this time. I get a faint no signal found box displayed and no sound. I connected a HDMI source as well as a regular cable tv source. I do not have the remote, and it seems none of the button controls on the side of the tv have any effect on the picture(menu, vol. up/dn, Channel up/dn). I cannot seem to change the input source.(no sound)?
I've taken the back off of the tv and found no bulging/leaking capacitors. No burnt components that I can detect. I can hear a ticking sound coming from the Ysus board near the Hybrid IC's. This ticking is in "time" with the flashing of the screen.
Can it be assumed the Ysus is bad? I have done a preliminary check of the voltages, and eveything appears nominal.
Thanks for any replys and help.
