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: 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: 47" vizio died

Very high failure rate on this brand. Even after repair, something else will fail. Cut your losses and buy a brand name set.

Logic Control D Board got nothing to do with this problem. This is your main power supply gone bad(usually not the sub power supply). I just repaired my VIZIO by replacing main power supply. Just remove back cover and your board will be right in the middle of the screen. Just get board part/serial # and google it. My best price was through eBay(around $100). Everything is fine now.

TV does not turn on.


You will not be able to see the fault with your eyes. You have replace the capacitor on power board or replace the power board.Sometime the value of the capacitors will change due to the heat produced by other components in the power supply. Its can make troubles. So try to replace the capacitors first rather than looking for physical damages.

Which circuit board on my Smart TV might be broken after a possible lightning strike. There are two main ones. The power is getting to the unit, but I can't get the menus, connections etc to work.


Nobody can predict, what might have been happened to your TV after a lightning strike. Do you thing anybody can? Is any technician have a super-natural power to predict the faults that might have been happened due to lightning (More than 10 Million volts to start on stroke) ? Can you?
Sorry.
Contact the authorized service center. OK?

I will start from the beginning. Back in Sept. my vizio tv would just randomly turn off here and there, but would always turn back on. Mid october the tv randomly turned off and never turned back on.


Claim lightning damage, put old boards back in it, sell new boards on ebay while a shop fixes the set for free (minus deductible paid for by selling ebay boards). Tada, repaired!

Or just sell the panel on ebay and buy another tv. Don't break the panel shipping it. 25366436-l0u5xrrbjmm23votbgnhzwek-1-0.jpg

Tv wont turn on fuse is good


does the vizio logo light up orange ? If so and it doesnt turn white then the main board would be suspect. If the logo doesnt turn orange when its pluuged in then its the power board. You can get either board from www.tvrepairworld.com
