Thank you for putting this video together, it was a huge help! I have a Vizio E601i-A3E that went black with sound. I could see the TV with the flashlight test and went through this entire video, pausing to test along the way. When I would turn on the TV, my backlight would stay on for a few seconds and then turn off so I used your guidance on the voltage test of the backlight circuit to help me diagnose that it could be a power board problem. I kept testing everything including the T-Con board but the power board seemed to be the part that needed replaced. I bought the part from Shop Jimmy as you suggested and installed it and the TV works great. Thank you again and I know where I'm going next time I have a TV issue!

Like your videos, very informative. I have Vizio 70inch LED TV. Model M70-C3. Black screen, no backlight. The power button lights up and the optical audio port lights up. I removed the back panel and checked the voltages on the Power Supply board.connector to Main Board, standby voltages for AC det =3.96, PS on =5.13 and AU =12.. Pins 8&9 VS =12v. Pins 13&14 T-con =12v, however pin 15 T-con on =0v. Also T-con connector pins 1,2,3,4 measured 0v instead 12v. Checked output voltages on LED Driver connector. Pins 3-8 measured 34v instead of 24v..Pin 13, vsense =2.6v. To summarize, zero voltage output to T-con board and higher voltage 34v instead of 24v going to LED driver board. Can you advise me on which board I should replace. My initial thought was the Power Supply board, however I guess it could be the Main Logic board not setting T-con on. Appreciate your expert advice.

Excellent video! I am having almost the exact same issues with my Panasonic TC-39AS530U. TV turns on, screen flickers 3 times (I can see the LED lights flickering in the back), then I get a blank screen with 1 LED flicker (error code 1 I assume) then just a slowly blinking red LED. There is no sound and I can't turn it off with the remote. I have to press and hold the power button on the side of the unit or unplug it to turn it off. I have tested my power supply board. ALL 3 test points (standby, LED driver, and main board) maintain voltage when it goes from power on to blinking light. However, the pins on the connector for the main board and driver board go from 16V and 24V respectively down to 0 when the light starts to blink. There are 3 test points on the main board, 5.3V, 12V, and 15V. The 5.3V (standby) maintains voltage when it goes from power on to blinking light, the other two do not, they go to 0. Would that, along with voltages being maintained on the power supply board, indicate that this main board is bad? I really hope that is the case as I do not want to get into replacing LED strips. Thanks and keep up the great work! P.S. I have put in new power supply and T-con boards and the problem continues.

Great and helpful video! Quick question, if there is no apparent backlight in step 1, what's the next step? LED Controller board replacement or continue troubleshooting? Main board gets red LED lit when plugged in. Then when power button is pressed, that light turns pink and the power indicator light on the front of the TV comes on solid, then blinks for 34 times, then fades out. After this, the pink LED turns back red.

Her tv's t-con board is not accessible without moving the main board and power board, so I can't test it the way you indicate plugged in.. I should be able to test the power out of the power board to the t-con board, is that enough to say it is the t-con board that is bad? How do I differentiate between t-con and inverter board? dwoods

I fallow your vids the best I could but as you might know my TV has 10 boards in it not just to 2 or 3 in the vids.

Working on my Vizio- have followed your videos to get started. TV won't turn on- I get the white LED when I press the power. Nothing else. No backlight. Can't see anything with the flashlight test. Standy power is present on the power board. I get 5.2 volts at the two places indicated and 12 V and 12V audio connections all check at around 12 at the main connector. The big cap reads 160 V for what that's worth so I'm guessing the power supply might be fine. At the second connector which appears to go to the LEDs I read 26 volts on two wire that are labled LED and less than one volt on the other two connections there. Photo available if needed. The TV was working fine but then it sat for a year unused. I was trying to put it back into service. Appreciate any help. J

Hey love the content--was hoping to get your opinion on an issue I'm having with my Sony XBR65x900H LED smart tv. Basically, it sometimes turns on/works fine for a few minutes before the backlight flickers, turns off, and the tv blinks 4 times. I've checked the boards (power, LD, main) and noticed that as it starts flickering, I also hear crackling/whining from the power board that appears to be in sync with the backlight flicker. I thought this might mean a power supply/capacitor issue until I held the power button while plugging the TV in, and was able to see an "Updating" screen for well over an hour (backlights on, picture on screen); so this makes me think it might be another component failing? Any tips on an approach to diagnosing which specific board/component may be failing? This is more of a hobby than something I must have fixed, so any insight is appreciated!

I am having the same issue with the second ribbon cable reading 0 V at pin 1, however, my TV is displaying a back light glow with no picture. Did you ever determine what the cause of your problem was. Do you know what parts needed to be replaced (main logic board, t-con board, power supply, ribbon cables)?

How do you how many volts should be going to the back light strips? How did you know it was 164 V if it doesn't say next to the connector?

Exactly. But I measured mine and it was a steady 192 volts on all 3 leads. I believe it has something to do with the brightness of your display or the backlight brightness. I've seen that on a Toshiba recently. Dim your display and of course the voltage should drop.

I have audio but no picture on my E701-a3. I have backlight, but I’m getting 176v instead of 164v to my LEDs and I have 12v on the first T-con feed but 0v on the second (lower ribbon). Is this indicative of a T-con board issue, main board issue, or possibly both?

Working with 70" Vizio TV (looks identical to this). All readings up to LED 1 and LED 2 were pretty accurate; however, LED 1 and LED 2 are sitting at 174. Is that a problem?

Hey Tampa Tec, I have a strange problem and I hope You can help me cuz I'm at a stand still. I have a 50" Vizio 3D Model M501D-A2R . I've replaced 3 boards , power supply, logic , and tcon boards with ones I bought on Ebay and still doing same thing . Ok here's my problem, when watching it , it goes fuzzy then back clear about every 3 seconds . The picture is awesome when its clear . I have a short video and put it on the input screen to see the problem easier. I looked it up on KZitem and a bunch of people had kinda the same problem but no one knows what it is . I was so sure changing the 3 boards would of took care of it . The guy I got the boards from had a LCD screen issue with the TV. My neighbor owns a TV repair shop and you know how people are , they don't wanna give out free info , he said they are throw away TV's . It cost $1100 at the time about 4 years ago . I don't really wanna throw it away . HELP PLEASE !!!!!!!!! I can send video if you want , just let me know where to send .

I'm determined to fix this thing as long as it's not the buffer boards on LCD , I'm thinking it would be like a relay type thing or transistor controlling the every 3 second problem, lol

Did you ever get this resolved? It definitely sounds like a main board issue.I'd get one from a seller who actually sells tv parts and knows what they're doing vs someone who just thinks their issue was a bad panel when in fact it was the main board.Let me know how you make out please.I try to stay on top of the latest issues with certain models.

I just got the same tv from my brother in law and am determined to fix it. Mine won't turn on either. But I have standby voltage and return voltage from The main board. No backlight normally but it willflicker on briefly when I disconnect the cables from either the power board or main board. Thinking T Con is the culprit. Any other thoughts would be greatly appreciated

Hi, my Vizio turns on, backlight and sound work but no image. I narrowed down the problem to main board or T-Con. I’m not getting any voltage from the 41 pin cable going from main board to T-con. is the problem the main board or T-Con? Don’t want to replace wrong part and it ends up not being problem.
