Vizio SV471XVT Logo Display Light Flashing Orange & Making Noise When Turned Off

Vizio SV471XVT when turned off at power switch the front Vizio logo display light flashes orange and makes an electrical noise in conjunction with the light flashing. When powered on, the noise goes away and the light stays solid orange. I'm trying to figure out if this in an inverter, power board issue or something else with the Vizio display logo light. Volume up/down work with buttons on side of tv but no longer with any remote control.

SOURCE: Power is there, but TV won't turn on

stored voltages are high no touching these circuts becuase they hold charges and alot of screws.
fualty capacitors you say after a while it stays on theres a full charge in the unit theres some type of discharging effect on the set after its off for a while. voltage goes to low or unstable after it is off for a while. your better off getting the service docs for this set if you want to diy..other wise get a tv tech to check it for you. hope this helps

SOURCE: Orange light is all I get.

99 percent its the mainboard not the powerboard, especially if you have amber led. The mainboard swap is pretty simple if you can get the parts.

SOURCE: I have a 32" vizio.

Right now the 5vdc standby power supply section is working, but the rest may not be working, check to see if you do have 24vdc feeding the backlight inverter board and no bad caps, if not, try disconnecting the power cable to the inverter to see if you get the 24vdc back. The TV should come on without the inverter connected, you will get sound but no picture, then you can try to repair or replace the inverter board. Unless the you may have problems with the main board, but you need to check all the voltages and signals first.

SOURCE: Vizio E550VL won't turn on. The vizio logo just flashes orange.

Good day!!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

Orange light on vizio no bad caps


You may be buying a main board, only a few guys in the industry even bother servicing main boards. Outside of a bad cap, fuse, or regulator its time to replace the board. If you have standby power, and you're not getting the "PS ON" signal from the main board, your main board is bad!

Not powering on


Change input device to some other like a DVD player and see.
Switch off TV, switch off power, remove plug and wait for 48 hours and retry.
If problem persists, call in a qualified service technician.

Where is the backlight inverter located in vizio sv471xvt?


Larger sets such as the one you have, will have two inverters. They usually are attached to the backside of the LCD panel on the left and right sides. If you don't see them there, then your inverters are built into your power board. If your power boards are either one of these below, then that is the case. If your inverter circuit is at fault, you will have to replace the entire power board.

Solutions (2) Best Solution That little fella is only turned off by unplugging it. If all those little lights in America could be turned off we could do with one less nuclear power plant. If unplugging it is not an option, my wife's solution is to cover it with a piece of black tape.

remove all screws on the back of the tv, carefully pull off back cover. you will see two circuit boards one on the left (Power) and one on the right (Video) on the Video board there is a small plug on the right side with a yellow, white and red wire going into a small white connector. the red wire is what controls the orange light on the front. now that the plug is pulled turn it over and you should see a small white plastic piece that holds each metal connector on the end of the wires in. pry this piece of plastic up for the red wire and pull at the same time, the wire will come out of the connector. now tape the metal connector with electrical tape and tuck it behind something or tape it to the chassis. plug your connector back in. put the rear cover back on. now your tv will only show the vizio logo in white when you have the power on. If you wish to disable the logo for both orange and white just disconnect the white plug completely.
