    Also check +5V and other low voltage output on power supply board that goes to main board. Some times if power output voltage are less than standerd it can caused to no proper boot up of system control chip.

I have a vizio gv42l fhdtv10a I have no picture or sound.


Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

My vizio VO47L FHDTV10A has no picture but vizio symbol turns white when I turn it on! I tried checking fuses and the ones I found were fine but mine doesn't have those three fuses everybody talks...


I had this problem with VT470M and the white light would come on but the screen would freeze on opening screen and then after a couple times the white vizio light would come on but no picture no sound. I ordered a new main board after troubleshooting all the voltages and it worked. Vizparts.com trade in for 150.00. Well worth it. The main board tells all other things to turn on. The white light is your standby power which is good. Probably ur main board and ordering a new one worked for me.

How do I test a High Voltage Transformer on my Vizio VU42L-FHDTV10A?


It could be the main board. The main board controls the standby light on the front of the set. Check and verify that your 5vdc standby voltage is working. Next, I would check the "on" or "ps on" input on the power supply board. When you turn the set on (either my side buttons or remote) the main board should send a 3.3vdc signal into the "on" terminal on the power supply. This "on" signal from the main board turns on the other half of the power supply thus turning on your set. If you are not getting this signal from the main board, I would suspect the main board. To test your power supply, you can simply put a jumper from 5vdc to the "on" terminal on the power supply. Your 12vdc, and 24vdc power supplies should then become active.

I have a 42 in. Vizio Galleria and need to remove table top stand so I can wall mount. How do I remove base stand?


1. Unplug all of the cables and cords from your GV42L FHDTV10A.
2. Place the GV42L FHDTV10A face down on a soft and flat surface (blanket, foam, cloth, etc) to prevent any damage to the TV.
3. Pull the stand cover off by squeezing the sides to release the retaining plastic tabs.
(This is probably the trickiest part to find this, just feel around and don't be too rough with the plastic)
4. Remove the four (4) screws (screw's specs: M4, 0.7 Pitch, 15mm long) so that the stand base can be removed.
5. Gently remove the stand base
6. Now, the GV42L FHDTV10A can fit securely to a mount (sold separately) by utilizing the mounting holes in the center of the back panel of the TV. Please make sure to read the instructions of your specific mount to properly hang the GV42L FHDTV10A
