Re: Vizio M50-C1 - it turns on then turns off
I got some time today and got the main board out. There's no signs of bad capacitors on the main board that I could notice. How would I be able to test it? Would I need to solder it out to test? Any other suggestions on components that I would need to check out?
Thanks...

Re: Vizio M50-C1 - it turns on then turns off
Thanks man. Just checked and its 395V. Tried looking at the main board and not seeing any bad caps that I can notice. I tried removing it and looks like it has some adhesive that I cant pull it out. You think that its ok to pull it out to check the whole main board?Leave a comment:

Re: Vizio M50-C1 - it turns on then turns off
I got it turned on again. A thing that I noticed is that the power indicator light is very faint. I remember this should be bright when turned on. It became unresponsive after some time and had to unplug. Went to the same loop process again. Is 22V low for 24V pin?Leave a comment:

Re: Vizio M50-C1 - it turns on then turns off
I was able to turn it on again by several tries of the power cycle (unplugged then hold power button. Did a factory reset. Finished with the setup then having that same problem again. Turn on -Vizio logo displays - Turn off - then would turn on again after about 2 mins. Like it can't load its firmware. I'm not sure if its already a bad main board or just a bad firmware or something. Hoping for some other suggestions. ThanksLeave a comment:

I do get the backlights on. Screen would turn on then the vizio logo appears on the screen, before it would turn off.Leave a comment:

Re: Vizio M50-C1 - it turns on then turns off
I see. How about the 22V for the 24Vpin? Is that ok? Would it then be the main board?
Read some posts that this might be bad EEPROM.Leave a comment:

Re: Vizio M50-C1 - it turns on then turns off
Tried testing the power supply board without the wiring to the main board. The 12V pins still shows 19.1V. Looks like a bad power supply. Hopefully someone can guide me on how to test for bad components for the power supply board.Leave a comment:

Re: Vizio M50-C1 - it turns on then turns off
Just got off from work. But yes, 19V on the 12 V pins. I double checked it. There where 6 pins that says 12V and all had 19V. Is it a bad power supply?Leave a comment:

Re: Vizio M50-C1 - it turns on then turns off
Pin 5V - 5.15V - 5.17V
Pin 12V - 19V - 19.1V
PS ON - 0.009V - 3.69V
DIM - 0.002V - 3.13V
ON/OFF - 0.002V - 3.3V
Pin 24V - 0.001V - 22.15V
Pin 24 V goes to the board on the middle not on the main board.Leave a comment:

I figure I need that. I'll be doing that in a bit when I get back. I tried to look for signs of bad capacitors and found none. ThanksLeave a comment:

Vizio M50-C1 - it turns on then turns off
Hi,
I'm new to the forum. I'm having an issue with my Vizio M50-C1. I plug it in, power indicator on lower left side lights up then turns off which is normal when first plugged in. I press the power button, power indicator lights up, Vizio logo shows up on screen, then turns off after 3 secs. I see a faint light on the power indicator after it turns off. I got the white LED power indicator like this but doesn't fade completely off.

Re: VIZIO E320VL Powers on then shuts off within a few seconds
Hi,
I'm new to the forum. I'm having a similar issue with my Vizio M50-C1. I plug it in, power indicator on lower left side lights up then turns off. I press the power button, power indicator lights up, Vizio logo shows up on screen, then turns off after 3 secs. I see a faint light on the power indicator after it turns off. Power button does nothing. If I leave it plugged, it will power up after a minute and shows up the vizio logo screen then turns off again. This will cycle continuously.
