    Is there anybody fixed this issue of GV42L?
    I replaced the 180uF, 450V Cap. and U27(Reset IC), but it does not help.
    I don't see any bulged cap. I checked 2 fuse on the mainboard and one fuse on power supply and they are OK. I checked fuses on backlight converters and they are also OK.
    When I plug the power cable, I have these:
    1. Clicking sound from the power supply,but VIZIO LOGO is orange color. I can have 5V(standy), 5V, 12V, 4.7V power on and 24V. Howerver, I can't have BL ON/OFF.
    2. No Clicking sound, VIZIO LOGO is orange color. Only 5V(Standby).
    3. Sometimes LOGO is white when I plug power cable, but it turns to orange.
    I don't see any bad capacitor. Anybody knows what is wrong?
    Is the Clicking sound is normal?
    Thanks in advance.

May be a bad power supply, which is a common problem with these units.I have a GV42L 42" manufactured in march 2007. It works perfect except the screen has a fracture on it. The warranty is voided because we damaged the screen. I can sell this to somone who has a good screen but needs boards or speakers, etc. Or I will buy your tv that has a good screen but damaged boards in it.

The main board has failed. Replace the main board will fix the problem.

By the way, where did you buy the TV? If you have bought it from Costco then try to give them a call to see if it still under warranty.

Hope this will help.

there are several possibilities. first if the unit comes on and the "VIZIO" light turns white, but no picture or sound, then the main control board is most likely the issue. could be the LCD control board(s) depending on model one or two. and ultimately could be the power supply on the upper side....if the "VIZIO" light does NOT turn white, the whole power supply unit is out. after that, would have to scope the circuits to find out. Seems that the control board is the most common and tends to happen on many different sizes. new board will be around $350.00. Might get lucky and find a used one, but it MUST be EXACT part or it wont work right. if you dont find one or want to sell yours for parts, id be interested in the screen. can reach me at kmarlin@grandvalleygolfclub.com. thanks, keith

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

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.

Check all electrical connections. If standby light is off when plugged in, probably needs Power Supply board replaced. If standby light is on (Orange/Amber color) may need Power Supply board and or Main Board. If set was shutting down on it's own leading up to it not powering on at all, may need Main Board, and possibly Power Board as well. If standby light has changed from Orange/Amber color to Green, the set IS powered on, and you have an issue other than power.
