Ok folks,been reading for the last 3 hours and could use a little guidance.I have a unit that went completely haywire last night.It displayed horizontal multicolor lines and was making a terrible squealing through the speakers and would not respond to any button presses.It had to be unplugged to make it stop.
After letting it sit for about an hour,I plugged it back in and get the orange Vizio logo and nothing else.No response to buttons,or remote.Just an orange vizio logo.
After reading the forums,I have found some good advice on where to start looking,but so far have found nothing definitive.I work in car audio and security and have a decent electronics background.Im proficient with a multimeter and am completely comfortable testing anything you guys can point me towards.
I have visually inspected every capacitor in the tv and nothing has ruptured or shows any sign of buldging.This model has the singal long inverter board and the capacitors look good there as well.I have also tried powering on the unit with the inverter board unplugged and still no dice.It just wont do anything.
I tested all the outputs on the power supply and the only thing that actually has output are the 5V lines.Is this normal?
If anyone has any ideas on where to go from here,Im all ears and look forward to hearing from you all.
