Vizio E320VL won't turn on

[CraigR]

Vizio E320VL has the amber logo lite in front but will not turn on or do anything but have the logo amber. I checked fuses and caps "look" ok and I have 5volt but no 12volt at the plug. I was reading here on this issue and people mentioned chip U18 giving problem so I replaced that and still have the same issue. any help is appreciated.

You will not get the switched 12V until the main board sends out PS_ON signal to turn on the power supply.
You should check and report the Voltage readings of the regulator IC on the main board in the format as shown in this thread:

there is a very good chance of a bad eeprom chip, but I will still check regulators, HDMI chip for over heating and the main board cpu for over heating. Just to be on the safe side.

sometime heating up the eeprom chip with a hot air gun will help determine if the eeprom chip is the problem. its might power on.

I going to go with a bad EEPROM, seems to be the consensus repair on this line of Vizio Panels as I have had 2 that both needed it.

Just my 2 cents worth.

According to post 1 "I was reading here on this issue and people mentioned chip U18 giving problem so I replaced that and still have the same issue. any help is appreciated." he did replace U18 EEPROM IC, http://www.shopjimmy.com/vizio-e320v...eprom-only.htm

Possible he got a bad one or the wrong one? I know these are VERY susceptible to static discharge damage.

The first time I ordered one, they sent me the wrong one in a package that had the correct model number, when putting it on we didn't noticed it and the TV wouldn't come on as before. After the right one was installed it fired up and is still working.

Vizio panels give me a headache!

I just got an older Vizio GVL42 that would do 2 seconds to black, no audio or nothing... Was about to toss it since it was only 720p no stand or remote but then I did a quick search and if it was used as a PC monitor in VGA input and was powered down suddenly or power outage that it would cause the panel to not fire up all the way and shut down as soon as the backlights kick on.

SO to fix it, I read all you had to do was when the TV was in standby HOLD down the INPUT button for 5-10 seconds and it would power on the TV and move it out of VGA mode.

So I tried it and it worked, and is still working.


Craig, you might want to try holding down the input button for 5-15 seconds to see if that works. Worth a shot anyway

I would check out the voltage reg. like BudM says. The unit is not powering up completely, which indicated a power problem. The software seems to be saying it will not go any farther because it is reading an error on power up. Perhaps something like holding down a button clears some error register I do not know.
