LED LCD TV REPAIR, DOESN'T TURN ON, NO PICTURE SCREEN, VIZIO XVT3D47 FIX

[@TampaTec]

Update: Tv still works as of today! Electropartsonline.com these tv boards lasted years.

[@tody78able]

i fixed mine lg 47sl80 ccfl backlight :) i had to replace the main power supply board which i managed to find for 38€ with postal fee :) then i heard a sparking sound from a display and had to take it apart to find that at the end of one tube, there was some arcing going on... i remade the insulation under the spot where it was arcing and rolled all the tubes to revive the connections, clean all the dust and smudge out and put it back together, which was even harder then taking it apart... and it works :) thank you man! i saw most of your vids :) you helped me a lot! regards from sLOVEnia!

[@LoneRider1836]

You have inspired me to troubleshoot and repair a VISIO 39" TV that was completely dead. Power supply tested good, following your guidance in checking it. I found an inexpensive main board on Amazon, used but good. Ordered it, installed it and turned on a TV I was just about to set on the curb. Thanks for your clear and in depth instructions.

[@terrydavidson9814]

Cannot say enough about this video. Followed along (because I have the same set) and it ended up being the T-Con board. It was a bit of hard find on the replacement, but prevailed and have a working TV now. Thank you !

[@RejectedManiac]

Narrowed it down to the PS by isolating it and was still blowing fuses. Figured I would just grab the board rather than troubleshoot parts because I just don't have the time right now. Ordered the board and took a while but they upped it to USPS priority and made it here. Put the PS in and works perfect! This was the perfect curb find! I highly recommend them and give them a little time because it may come from a different warehouse. Thanks!

[@traversecitymall3144]

I really enjoy learning from your videos. Sadly we are such a throwaway society anymore that when a TV has issues people just toss them and buy new when they probably could be repaired for nominal $$. I wish the skilled trades would come back, can't even find a local TV repairman anymore. Thank you so much for sharing your talents, you help so many people out. God bless you.

[@timo4040]

I know that this is an old video but you did a very job and got me in the right direction. Thanks TambaTec

[@cabasse_music]

just got back to atlanta from visiting with family in tampa a couple of days ago. a few hours ago, i was searching for how to run speaker wire through studs since i was wanting to put some in wall speakers in my kitchen and stumbled across your video on a flex drill bit. now, a few hours later, i was looking for how to replace/repair the main board of my jvc jle42bc3001 and again have come across one of your videos. not sure what the universe is trying to tell me but i'm listening!

[@1miltond]

Great video for a layman like me. I have an LG TV 65inch where there is no display on the screen, not even the remote functions are displayed, its an absolute black screen (audio is working fine though). What would you suggest?

[@swardmusic]

[@jeromeiglesias1839]

Any idea if the tv remote does not work and try new remote still the same. But manual power tv does work.

[@susanbuckland546]

Hi tampatec. Did you no when your tv Red light blinks it is indicating that which TV part has gone wrong and its a code for the TV and what to do so I thought I would let you know as I have learn quite a bit from your videos thank you very much my TV is nearly fix I changed a capacitor and know the red light just stays on know so I just need to get a new main board when they get them back in and hopefully it will be fine

[@injoelsgarage3934]

Your videos are always informative.! Thank you for your time and sharing. Joel

[@Garth2011]

Good review. What about other Vizio models? Are the symptoms going to be about the same for diagnostics? Case in point. We have a 6 year old P702ui-B3 that began to power on without the V logo, it had back light but barely could see the menu when activated. Sound worked fine. Turned the unit off, then back on and it displayed the V during boot up and functioned just fine. This process repeated itself every time the TV was turned on for about 2 months. Then, while on we witnessed the picture begin to fade and alter then finally no picture but had sound. Turned the TV off and it never powered on since. So, the current status is, it will not power on at all and we did the reset procedure of removing the power cord and holding down the power button on the back for a minute. That failed to clear up anything. Called Vizio and they simply said it's not worth repairing, likely the backlight. At this point, we want to diagnose this and see if it might be worth saving since it was a rather expensive model at the time. Go through the same procedure as in this video?

[@stephentrutledge]

Good morning I had a HDMI cable that was grounded I didn't know about well needless go say I went to plug it into my Vizio 43 inch Smart tv it went off and will not come back on as I touched the HDMI cord to the socket there was a small spark then the TV shut down what board should be replaced?

[@edgarestevez2074]

Great video. But I have a question for you. I have a RCA 50" LED TV and sometimes start and other don't. The red light is on. I don't know what is going on. I'll appreciate any help. Thanks

[@christroth6416]

Hi when I plug my inverter board in (hyundai Q321 inverter board the tv will not come up and stalls to standby with power drops. When unplugged the rest of the tv works, all the capacitors look ok throughout the boards. I am fairly sure the psu is ok as the main board works as the tv tunes and gives audio from tv channels but stalls to standby when the inverter board is plugged in do you think a new board will cure the problem. Over the past year the tv has taken longer and longer to come on like an old valve tv.)

[@thomasbryant5511]

I have a Sharp Aquos Model# 65N7000U. Last night we had a storm come through and when I went to bed the TV was fine. Got up this morning and the red LED indicator light is not on and the TV will not come on. TV is plugged into a surge protector but also has an outside antenna plugged in. I have tried all of the resets nothing works. Any help would be appreciated. Thanks, Thomas

[@geofreykomu1100]

Hv Understand that if there is no 3v coming back from the main logic board to the power board that's mean (logic board out) thanks for the teaching always learning electronic trouble shouting from u(keep on with the good work)

[@nathanavalos5793]

I need your help I have a 65” rca model# sld65a55rq that turns on a has the glow like the one in your video but no picture I replaced the t-con board but it still does the same thing what else could be the problem

[@misganawzerihun4781]

Hi dear Mr. Tampatec; really you are doing well!!! i hope you will help me for the following question: when i am watching TV (tv model SONAC Flat TV 32" ) it is suddenly switched off totally! it was working about 1 year after i bought. what will be the problem??

[@mambrake]

I have an Element smart Fire TV. It turns on and after a few minutes the video goes but I have backlight and sound, if I turn the TV off and on then it works again for a few minutes.. any idea? TCon board?

[@brandonjones3677]

I have a rca 52 in tv that has back lights but no sound or picture. What do u think would probly be the board to replace? Would it be the logic board since the power seems to be working fine?

[@willbailey1488]

I have an old LG tv and the standby light is on. Sometimes it will turn on with the power button and sometimes it will not. When it's on, the power button always works to turn it off. The rest of the functions work when it does power up. However, it will not keep the current time when I enter the current time. I reset to factory specs on the unit and it works normally for awhile after I do that. But then it goes back to powering up occasionally and the current time sets back to dashes, it will not keep the time. Here's my question: Is this more likely to be a problem with the power module or the main module? I want to try to replace them, but I wondered which one I should try first. On computers, I know there is a battery that keeps the current time clock running. I wonder if there is a similar battery on these televisions and if there is, which module does the battery sit on? Thanks for your help.

[@smithmcbama07]

We just had a bad storm and my Vizio e470vl 47" will not power on. Do you have a video on how to check this?

[@w3vjp568]

We have a Vizio P65-C1 that won’t power on - we’ve already replaced the main PSU board, which didn’t fix it. Any suggestions on what diagnostics to try next, to identify which board is faulty?

[@joesno406]

Thank you for your helpful videos !! You are very nice to help the people as you do ..Thank YOU!!

[@williamiseman4121]

I have come a cross a Vizio M550NV. When powered logo is Amber. Push power button and nothing where should I start looking??

[@Liberty309]

BTW I have this same tv that I have not been able to get running. Half the screen is out so I assumed it was the T-con board. I ordered a new one but it didn't fix it. I swapped the ribbon cables too, no go. It's not the leds either. I am assuming the problem is on the section where the ribbon from the T-con plugs into that side of the screen. I would appreciate any advice you might have on this.

[@brentmayfield9434]

I have a Vizio model E502AR. Power surge/lighting strike issue. Have replaced all 3 boards (power, main, T-con) Power light (Vizio emblem at bottom of tv) comes on now and stays on but still no sign of any picture. Black screen only. Any ideas?

[@ElYarderoOfficial]

Hey Tampa, you're videos are awesome man, thanks for teaching us all about the electronics we use on the daily. My vizio TV (e500i-b1) when i power it on sometimes it blinks the backlights, then you can hear sound, but its black. I turn it off and try to power on, sometimes it will work and display right and wont turn off during watching or gameplay. But once i turn it off it it may blink the backlights or not come on at all, again sound etc still there. if i unplug for 5 mins it turns on normally as soon as you plug it in, but it'll go back to the behavior i mentioned. Thanks for any reply, and keep up the great work on the videos.

[@TampaTec]

Jehu Garcia check volts to backlight boards if steady and ok then can be bad backlight perhaps.

[@charleschapman2428]

What could cause two boards to go out at once, or was it one board going bad causing the other to go bad also. Thanks for sharing you knowledge.

[@lgmnowkondo938]

it would seem to me that the company you order the board from probably just replaced some parts on it...how often are you able to just repair the board, instead of orderig a new one?

[@warneruselton429]

Great video, I have a 49 in vizio no power . I will try what you did ,if works I will let you know. Thanks

[@oscarzuniga4897]

Hey Tampa tech, I have a Visio model # m43-c1. The standby turns on then fades then comes back on then goes off, and no picture. I tried the light test but see nothing. Any advice would help. Thanks.

Hi I have a Samsung TV mdl. UN60J620DAFXZA. When TV is plugged the red light (by power button) is blinking twice and blue screen is flashing. I disconnected the main board RIBBON from the power board and it's doing the same thing. Is the power supply board bad or the main board. I have video to show if I can send it to you. Thanks for the help. BC

Hello, My Aquos Quattron 60 inch turns off by itself. Do you know why it does that? I have read comments that lights are flashing in some cases but in my case the TV just turns off with no flashing ligths. Let me know if you have an idea. Thanks a lot.

[@adelaideinvigilation5230]

You mentioned that the board was refurbished, do you send the faulty boards from TV that you have fixed to them to refurbish, ie do you recycle the boards ?

[@christof3496]

Love your videos! I was wondering, you didnt get a voltage on the powerboard when you pressed the on/off twice. How did you know it wasnt the powerboard then?

[@robertdegeorge3678]

Great videos! My Vizio won't power on. After doing as you suggested, the vizio light comes on dimly and fades as it does when turning off. I already ordered power supply from electropartsonline as it is a very rare part. I got his last one. Vizio 65" M3D650SV 0500-0507-0920 LCD Power Supply

[@DeadThumbGamer]

Have you ever swapped screens from different model TVs to repair one that had a cracked screen or other screen issues. Such as a damaged outer layer or viewing layer of the screen? I have a monitor which has this issue. I think my nephew scratched the top layers of the screen. When turned on w/o an input, where the screen is just blue. In a couple of areas I can see white, which I assume to be the backlight shining straight through. Is there a way to fix & what would you recommend? Thanks!

[@TheEsco1975]

I have a hitachi le55a6r9a I changed both tcon,and the main board still I get no picture it's still black. I used a flashlight and I seen the volume button! I need to change the inverter where is that located

[@d.j.9961]

You seem well versed & I am sure that you could definitely assist me & my tv! I have a 55" Vizio model m550vse a few days earlier, I turned off the front indictor light to conserve bulb life & a few days later, I turn on the tv & the screen lights up momentarily & then, Goes black. It has audio! Every time that I turn it on, The screen lights up just for a second or two & goes black! I tried the flashlight trick & I see nothing! Which board do you recommend replacing?

Great video sir I really appreciate it keep up the good work 👍 👍 🙏

[@adrianjones241]

Quick question - love your detailed videos by the way. If the TV screen turns on for a while then goes off in less than 1/2 second could this be the T-Con board or the LCS backlight circuit?

have a dead 60 inch visio led. Power surge from hdmi port fried the chips there. Changed out the t-con board figuring that was the issue. Still wont power up or have standby power. Power board fuse intact and no obvious burn or bulging capacitors. Have new power board on the way, but wondering if you have any ideas ???? love the channel, I've watched every video. That's why I'm still stumped !

[@TampaTec]

If surge travels through hdmi then main logic board is most likely bad, get tv boards at shopjimmy.com or electropartsonline.com use code tampatecfriend for discount 👍

Hi Tampa tec, I have 2 Vizio TV's. Both stopped working on the same day. I called Vizio, they say both need repair. I checked the internet, can't seem to find anyone who has my issue. Both TV's turn on. Both TV's work, screen, icon, input, etc. Both turn off about 3 minutes or less after turning on. I've completed all the resets I could find. Followed all the Vizio steps from their tech, but nothing works. Do you have any ideas?

[@heyyyyolo9028]

When was the Tv made?

[@handymanreality]

I love your videos on electronic troubleshooting & repairs. I am now shopping for a decent Fluke multimeter so I too can follow along & revive TV's. I have a Visio E60-E3 that I took apart to repair a sag in the very front screen layer due to some broken parts on the bezel. After repairing the bezel now the TV will not present the brand logo or anything on the screen. When I hit the power the backlight comes on with no indicator light, then the indicator light flashes once as the screen goes black before starting this cycle of backlight on/one indicator flash/black screen rinse & repeat. Got any guesses as to which board to replace while I look for a multimeter?

[@thinkfx3078]

Hey man so glad that I found your channel my mom has a Vizio tv, the picture comes up for a sec like in your video and goes off will try it out an let you know.

Hi Tampatec im from Brazil i love your videos, i have a Sharp LC 32r24b , when i insert the ac cable they give me blinking leds the power led and the ocp led alternating , i check my power suplay and i get in the conector to main bord the voltage ac=3.3v and the BU5V=5.2v if i press power buton i get a signal of 2.7v very quickly 1 secound from the main bord Ps On and theY all shutdown the ac voltage and the bu5v from stanbay gone to 0.6v. I try to arm the power suplay without conected to the main bord with a resistor of 1k betwin the bu5v and the Ps on, i ear a doble click from the relé and i do not get any voltage from 13v and others.

okay my model I don't think has T com board, And I have a working back light, I can leave one of the two ribbon cables connected coming out of the logic board and I can get Half my TV to work, but when I try with both ribbon cables It makes a bad high pitch noise coming from one of the boards and the entire image will have lines in it and, I'd like to note if I leave the TV alone unplugged for long time, and come back it works for about 5 minutes before it starts doing this again.
