My Vizio E320fi-B2 Won't Turn On Or Display Power LED

So I've been using the Vizio E320fi-B2 for about 7 months now.

But recently it stopped turning on or displaying anything on the power LED.

I've taken the backplate off and examined the internals, but nothing seems to be blown out or broken. But when I plug in the power chord and listen I can hear a ticking noise, like a bomb is about to go off.

Nothing actually happens other than the noise though.

My first assumption was that the fuse had just blown out, so I bypassed it to test that theory. (I don't have any tools to test voltage.)

No change though.

I set aside the project for a little while. But today while tinkering with it, I realized that the ticking was coming from higher up on the board. Not anywhere near the power input or fuse.

I'm at a loss here, anybody have any ideas as to what might be the issue. Can't really afford to buy a new TV.

Thanks in advance.

Neckbeard Prettyboy you need at least an inecpensibve multimeter to test a few things. LIke the voltages on your power board. The clicking could be coming from a relay so you will need to post some image of your boards etc. with your question. For that use this guide 기존 질문에 이미지 추가하기

Hi,

If you have only had it for 7 months, (was it from new?), verify the purchase date and then consult the warranty statement in the User Guide as to what you have to do to get a warranty repair or replacement.

There is a 12 month manufacturer's warranty on the TV.

Here is a link to the manufacturer's warranty statement.

The ticking noise you are hearing is most certainly coming from the SMPS this is the source that supplies feeds to the other boards inside your TV.

The reason for this can be varied for example a short cct has occurred whereas the smps will automatically sense a problem and shut down to protect itself from further damage therefore no supply to its satellite boards.

I could elaborate more but would not advise you or any other person to try the old adage "it must be a fuse"... In earlier times the day's of CRT televisions...vtrs...hi..fi....radio i have encountered many times fuses that have been replaced with :.. fuse wire....silver paper...screws...nails.... the most common one being silver paper wrapped around the original fuse.

My advice further is to seek professional help ...no easy money saving fix here
