Re: Vizio E321vl power supply question
Thanks guys. The 5V supply wasn't staying up under load. Picked up a supply board for $26 and the set works fine. Appreciate the help.

Re: Vizio E321vl power supply question
I'll check the load resistance from the main board when I pop the set back open tonight.
Thanks....

Re: Vizio E321vl power supply question
If the 5V supply is ok then wouldn't pulling it down to 0v have popped a fuse or does it sense a short and cut out? I'll bring home a few resistors from work and test it tonight.
Thanks....

How much of a load should the 5.2V standby supply be able to take before collapsing?
budm, I'll check the cap value and post a pic of the board tomorrow.
Didn't see any way to delete the other post. May a mod can delete it for me.
Thanks guys.

Found the TV with no power, logo is out, and not turning on with power button or remote. I did the reset with holding down the power button, waiting and plugging back in. When it is plugged back in the logo is amber for less than one second and goes out dark again. No power.
Power supply board has no voltages present at the connector while the...
