Re: Vizio VO47L FDHTV30A Picture but no speaker audio, clicking sound
Thanks for all of the replies. I went ahead and disconnected the internal speakers and will just use external speakers connected to the RCA jacks.

Re: Vizio VO47L FDHTV30A Picture but no speaker audio, clicking sound
I've done both of those and neither helped. I took the back off the TV and it turns out the clicking sound is actually coming from the speakers.
I may just use it with external speakers connected to the RCA jacks, and disable the internal speakers, if there isn't a quick fix for this.Leave a comment:

Vizio VO47L FDHTV30A Picture but no speaker audio, clicking sound
I have a Vizio VO47L FDHTV30A. The picture works well, but the sound only works through the RCA output jacks. The sound does not work through the internal speakers or the headphone jack. The TV has a rapid clicking sound when the tv is on that occurs about 4 times per second. The clicking sound volume is fairly low and is not affected by adjusting the internal speaker volume level. The clicking occurs whether or not I disable the internal speaker through the Vizio setup menu. The clicking only occurs while the TV is on.
Any idea what is causing the clicking sound? Any easy way to...Last edited by nbnb; 11-23-2019, 12:36 PM. -

Re: Vizio E370VA wont turn on
If I do this, and the backlight turns on, does it indicate that the power supply and inverter/backlights are good and that the problem is with the main board? Or, could the problem still be with the power supply?...Leave a comment:

Re: Vizio E370VA wont turn on
Does that mean the inverter board is bad and should be replaced?...Leave a comment:

Re: Vizio E370VA wont turn on
The LED1 does not light up at all. When I have 24.6 volts on PIN 1 of the inverter, the F1 fuse measured 24.7 volts on both sides of the fuse. Pin 14 was 0.28V, pin 13 was 2.46V, pin 12 was 0.09V, and pin 11 was 0.10V.
I attached some pictures of the inverter board with the cover off....Leave a comment:

Re: Vizio E370VA wont turn on
Thanks, and sorry. You are right. I had the correct voltage in post #3 for when the TV is off. I edited my post to note that it is 3.6 volts....Leave a comment:

Re: Vizio E370VA wont turn on
I plugged it in (so the TV should be off) and get the following voltages:
3.60 (5v)
3.60 (ps/on)
24.6 (24v)
12 (12v)
When plugged in, the vizio bezel logo glows dimly.
Pressing the power button, the bezel logo gets bright for about a second before dimming. I get the following voltages:
5.16 (5V)
0 (ps/on)
0 (24V)
0 (12V).
If I press the power button again, the bezel logo darkens and then returns to a dim state.
I don't see anything when...Last edited by nbnb; 11-06-2019, 06:52 PM.Leave a comment:

Re: Vizio E370VA wont turn on
Thanks for your reply. PS_ON voltage is 3.60 volts when the TV is off. When I turned the TV on, PS_ON voltage went to 0 volts and the standby voltage went to 5.16 volts. Also, the 24 volt pins measure 24.6 when off and 0 volts when the tv is on. The 12 volt pins measure 12 volts when off and 0 volts when on.
Is the PS_ON voltage supposed to go to 0? What else can I check to narrow down the problem?...Leave a comment:

Vizio E370VA wont turn on
I have a Vizio E370VA that won't turn on. It was working fine until I didn't use it for several weeks. When I press the power button, the Vizio logo below the screen gets bright for about 1 second and then dims. The screen remains blank and the Vizio screen logo never displays.
I have tried unplugging the set, holding the power button for 30 seconds, and then powering it up. That didn't help.
I pulled the back off and measured 3.66 volts on the standby port labeled 5V. I disconnected the main board from the power board and then the 5V port read 5.25 volts. Does this... -
