I have this same problem with my Vizio. Model E601i-A3
60" LED, believe. Maybe 64"

Anyway, the solution is much simpler than these other answers make it sound. 1) Unplug tv from wall.
2) Unplug all external devices (all HDMI ports, any cable hookups, any rgb/vga connections, and any speakers attached.)
3) Unplug USB drives/attachments.
4) Plug TV back into outlet.

It should power up just fine. Then you can go ahead and reattach all your devices WITH THE TV SCREEN ON, reattach your USB sticks and you should be good to go.

Every time the TV is moved or is unplugged for any period of time, follow these procedures. The real culprit is the USB drives - the TV, like many laptops I've had, can't boot up with them attached. Thankfully once the TV learns what they are they no longer have to be removed.

Screen is black but I can hear sound.


Most likely the power supply board needs to be replaced. It could also be the backlighting. A few TV's have a separate power board just for backlighting, but not many.

If you don't know what you're doing, DON'T OPEN THE TV UP TO FIX IT, THERE ARE HAZARDOUS VOLTAGES ON THE POWER SUPPLY BOARD, EVEN WEEKS AFTER THE TV IS UNPLUGGED!

If you don't know how to do it yourself, find some local Electronic repair shops, get quotes, try to find reviews on the shops.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced.

I have a vizio 42 inch model VO420E serial# LUKECAK1409419. when i turn it on i get a black screen but i have audio. it does this in every input. what can i do to fix this problem?


Most likely you have a backlight problem. To verify this, dim the lights in the room. Take a bright flashlight, turn on the set, and shine it on the screen. If you see a faint picture, you have a backlight fault. Your backlight inverter may be built into your power supply board. If this is the case, you will have to replace the inverter/power supply board

The TV has a section of it that is dimmed out and darker in brightness. Is this the Main Board that needs replaced?


Check the CCFL lamps used in the backlight section. These camps can cause this type of fault, as they are very like the flourocent tube lights that we use to illuminate our room. As it goes older, the ends of them will get burned, and the intensity will go low. Like ways is to the CCFL lamps to LCD tVs tool CCFL is the abbrivation of [Cold Cathode Flourocent Lamp]

I type slow, I have a Vizio M261VP LCD TV, I purchased it not working. I purchased a new power supply. A light comes on and flashes in lower right hand corner. I t does not flash on and off it flashes...


Good day sir chris!!!!

Welcome in fixya and I'm happy to work with you...

OK lets proceed to your TV problem..

The possible problem is not the power supply...There some shorted parts on inverter board,T-con board or main board so that the power will not initialize due to that shorted problem..

I teach you how to find which board is shorted or cause of that fault..

Just follow this procedure below.
  1. Open the back cover
  2. Look at the inverter board..it is slim board that have small transformer on it.
  3. unplug the inverter board first.Then try to power it on...
  4. If the LED on front of TV will not flashes from bright to dim it means you have shorted inverter board try to replace it..
  5. If the flashes remain..go to next step..Power off tv then reconnect inverter board,after that unplug T-con board..Then power on.
  6. If the LED on front of TV will not flashes from bright to dim it means you have shorted T-con board try to replace it..
  7. If all those procedure done but still problem persisted the only problem is main board..Replacing main board will fix the problem..
NOTE: When unplugging and replacing of all board make it sure to memorize all connection or its better if you take a picture on it for future reference..

Hope this solution will be helpful..Any rate will much appreciated..

Thanks for using fixya..have a nice day!!
