SOURCE: no picture or sound, light comes on in the front and have to unplug tv to turn it off.

I had this exact problem on my Vizio 47" HDTV. I removed the speakers and all the screws on the back cover. Took the cover off and located the fuses on the largest circuit board. The are in the upper right hand corner of the board. There are 3 of them in a row labeled LF 1.5, LF 3.0 and LF 3.0. The are white in color with copper ends. I took a volt meter and measured continuity across all fuses individually and found the LF 1.5 to be blown. The guy at the electronics store sold me a barrel 1.5A fuse and told me to soldier it across the top of the blown fuse. It took an extra set of hands but the TV works perfectly.

SOURCE: VIZIO TV Black screen. Cannot turn off TV without unplugging.

I had a similar problem after having a Vizio for 2 and a half years. I left the room for a minute, i came back and the screen went black. I didnt hear an arcing sound though. There was still power to the unit and you could see that the back light was working, just no picture, no sound, and you couldn't use any of the buttons. The only way to turn it off was to unplug it. It would then start up, with the Vizio logo going from orange to white, and then do the same thing all over, no pic or sound. I would check the ceramic fuse first on the board that gets power from the plug.

HOW I FIXED MINE: I ordered a new "main PCB" from tigerdirectparts.com (you can also use searspartsdirect.com). This is the circuit board with all of the inputs on it (hdmi, cable, etc.) I opened it up, disconnected the old one, put in a new one and now it works fine.I used both serial numbers on the board to search for it online. It cost me $144 to do it, but that's better than $450 for a new TV. My tv is the vx32l hdtv10a. I hope that helps.

For the cheap guy like me who will probably do more harm than good:
Also check for the F3 Fuse on that same main input board. It is located in the upper right corner. Hard wired fuses; very small. You will see F1-F4 (F4 is empty). You can solder a replacement fuse right over it. I would recommend piggybacking the fuse with a fuse you can replace. Will need the holder and a new fuse. 6 bucks.
Doesn't solve problem, but I can go another 2 1/2 years and the wife won't blame me for screwing up the TV in the first place.

My Visio E371vl won't power on with remote. I changed batteries & even bought a universal remote & no power on. the new remote works on other Visio TVs. I can turn the tv on with manual controls.


Dear Anonymous,
  • Unplug the TV for 20 Minutes and plug it back.
  • If that does not work, the remote Sensor on your TV is defective.
  • Take it to a repair shop.

My TV powers up and shows the Vizio logo on the screen but why no video or backlight?


I had exactly the same problem with mine. Called for warranty repair, as it was only 3 months old. The repair person swapped out the motherboard, and it's been good for 2 years now.

E371VL Vizio TV. This TV has sound but no picture/video. When the TV powers up you can see the screen light up momentarily with the logo "VIZIO", then the screen goes black. However, If you shine a flash...


The inverterboard is the unit that can go in safety mode after a few seconds after starting you can take out the ccfl tubes rail out of upperside of the screen a little to look if it will start be aware that you are working with high voltage come out the inverterboard , it can be happens that it will not start on bad capacitors and capacitors elsewhere not starting from mains power supply and one of the 2 step up transformers can be defect by too high a voltage
caused by bad capacitors or you have only a bad soldering of some interference suppression beads that are coils like below picture bad soldering can be in factory bad degummed of the resin on the brass wire a real ACER problem of some models but in any kind of backlight inverter can it be a problem . but most problems are in priority the capacitors . or solderings on primary active components.

No power on vizio E371VL


Vizio TV model E371VL turned on ok and had tv show on ch.4.
Turned on the DVD player and put movie dvd in and closed tray.
We have done thhis numerous of times and never had a problem.
This time " HDMI " was showing on top right of black screen,
then " No Signal " came up on screen, then went completely black screen. Called Vizio, they had me power off and unplug set.
Push and Hold power button on TV for 30 sec. to reset.
Replug set and Vizio (lighted) on lower front of set lighted normally dull orange. Pushed power button on remote and when set did not come on, then push main power button on side of TV. Nothing, no White " Vizio " from orange light. Is this a power supply (0500-0412-1020) problem ? Thanks, Sidney (sidneysites@yahoo.com)
