Question about Vizio Televison & Video

Open Question

47" LCD Vizio won't turn on. I have had this for less than 2 years. Worked fine the day before. My boyfriend tried to turn it on and play the Wii the next day and the Wii logo came up. Then he ejected the game that was in the Wii and there were blue, green, and red flashes darting across the screen. Now it won't power on at all. Orange VIZIO logo on bottom of TV frame comes on but dims after a second or two. We think it's the power supply, but not sure. VIZIO just tells me I should have gotten the extended warranty. I am being quoted almost $500 to have it fixed, but the part is only $81.00 online.

SOURCE: vizio 47" lcd no picture no sound has power

this could be one of two problem. first, check if you have back light. If you do then the problem is with the M/B. Second, if you don't have back light then the inverter is bad and needs to be replace.

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: 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

When I turn on my 42" vizio all I get is the vizio screen no sound and the remote will not work to turn it off.after being unplugged for awhile (days) i tried it again and it worked fine until i shut


You will need to get a diagnosis done on the set. It could be a power supply issue or a main board issue. Your problem is between one of those two boards.

My vizio VO47 L has a black screen and sound. I do get a light on the vizio logo on the front. I see no illumination coming out of the back of the unit. what is wrong?


Power Supply popped a cap and fried the metal resistor bank. Replace the cap C241 and solderer the resistor bank. Worked for two months then pop out again. This time the resistor bank burnt through. Bought a new power supply DPS-38cp-1a from ShopJimmi.com $56.00 Replace supply which lasted 1 year 1 day and the same thing happen. Same components. Got this TV free but its costing me time and money now.

Vizio GV42L LCD TV screen black when turn TV on first time


If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on.  If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.

Television will not turn on


My 47" Vizio wouldnt turn on this morning.....had a similair problem 3 yrs ago.....this is what i did and fixed the problem myself.....apparently you have to reset TV. Here is what has worked for me. So unplug tv power cord from the tv. Hold the power button and imput button together ( located on side panel ) for approx 45 sec......plug cord back into tv. Press power button on tv and voila !!!!! Tv came back on!!! I have had my Vizio almost 5 yrs. But have to call the unhelpful customer service atleast once a year.... I hope this works for you :)
