Did this video help you?

Den Von: I wish I could get the back of my VIZIO TV off that easily, how do I get the back off the XVT373V?

Mike Schmidt: As you state at 4:30, "It is 99% of the time never the fuse". I agree, it appears the manufactures are using the TV as a fuse to protect the fuse. LOL An oxymoron if there ever was one sad, but many times apparently true.

betaatomic: I picked up a Phillips 47" TV with a blown out area in the power board. A blown capacitor coated residue over about 15 square inches, and made a 2 square inch hole. It looked as if the transformer was melted, but it was merely residue from the cap. I replaced the blown cap and 2 bulged others, and saved the power board.

chris t: tampa i have a vizio 55inch lcd tv my problem is that my inverter boards keep burning there wire harness in between each inverter what could cause that to happen and could the inverters still be good my first inverter change the borad and all its components look good nothing looks burned can you help me 

Edgar Hernandez: I have a vision TVs model e321mv and it won't turn off and the led light it turns red place help me 

Sharon Doyle: My vizio had a screen come up that says "NO RGB SUPPORT power will be turned off." Then all power is shut down. Anyone know what I can so?

Dustin Kelsey: I have this same T.V. with a flickering back light issue intermittently after it warms up. Sometimes this is accompanied with some buzzing sounds. I thought it would be bad caps on the power supply, but they look good there as well as on the master and slave boards. The buzzing sounds like its coming from the slave, although it is mounted on the wall and tough to tell. My next step tomorrow is to test all the caps in all three boards with my meter. If all the caps test good, where would you move your troubleshooting efforts to?

frolfer13: i have a 55in LCD Vizio only 2 years old...it turns on but doesnt load up just the vizio symbol on screen...if i do hard reset a few times i can get it to load up but i feel like im doin damage doin that everytime i turn it on...any suggestions?

Mary Shrieves: I have a Vizio TV that comes on but want let me change channels or anything? the only thing that it shows on my TV screen is the Vizio logo? Please can anyone tell me what is causing this? Thanks. Mary S

joe castro: thank you....

House of peace: I have a Vizio that keeps shutting off. It does come back on but constantly shuts off at any given time. Please help and thanks in advance.

Janice Jenning: With the TV being so light I might make a shelf to put the TV on so the Kinect and other items can sit below it.

tlaloc1525 .: If it does not come back because a fuse, replace the fuse, however, if it is not the fuse, buy the power supply at ebay for less then $40 dollars, easy replace just like a PC.

James Ruffin: My Vizio TV comes on and goes right back off what could be the problem

Percy Mitchell: Hi guys! First the video was very helpful. I have the exact same one. Purchased the power supply but I still have the same problem blank screen. Bad inverter board(s)? Thanks for your help

Tampatec: yes, inverter board sometimes burns out power-supply..

scott trott: I have a sanyo DP50749 that wont power up at all, doesnt come on and go off just doesnt do anything. I watched the video on how to test the AC and DC with a meter and it has the 120 V of AC but nothing for DC, however I was under the belief that you were supposed to turn on the TV before you tested the DC but mine wont come on so to you think iys the power supply? I found the part at Shop Jimmy but want to be at least pretty sure its what i need nefore i make the purchase...thanks

Putra Alfaiz: thankz Bro...God Bless U..

Tampatec: yes my buddy tony got his vizio main board swapped out free after 2 years.

Tampatec: thx :)

AlexMurilloh23: Hey buddy, I have a Vizio M3D420SR, just yesterday I attempted to turn on my TV and the only thing that would happen was the VIZIO name would light up, I unplugged it for a good 10 minutes but nothing happened. Took out the back plate and based on a visual inspection everything seems to be good, no swollen caps or burn outs. any suggestions? thanks alot!

AlexMurilloh23: Do you think I can ship out my board to you? power and main? maybe you can diagnose and repair it and ill pay you via Paypal? these 3rd party repairs are expensive ranging from $125-$150 a board..

SylentCommando: Wow thats a bad burn LOL. I wonder how that got through quality control at the factory, Cap was probably bad from the beginning and ended up frying other parts in the process well failing. I heard vizio Tv is are made by Sony, I also heard that vizio is not a very good brand.

Godzilladeathmatch: will do...thanks..

Tampatec: might be bad caps in power-supply

tarantism: check your capacitors and see if they are bulging. My vizio wouldn't turn on turned out it just had a blown capacitor. look it up you may not need a whole power supply people

Tampatec: if you heard a pop there should be blown tv part on a Board maybe a capacitor, yes its maybe power supply. use a light and look and smell around for burnt parts 8^)

M.YT Gaming: I got a viewsonic 22" monitor which wouldnt turn on and immediately i saw bulged caps but i also saw a bad scorch mark, i look at the back at where the scorch mark was and it was about 3 SMD's that had burned up. I then got the same monitor in (simple bad connector) so i tried the PSU in it and thankfully i did because the panel was dead and so i didnt waste money on a new PSU :P

Tampatec: usually its the bad caps in the power-supply then maybe main board, but buy the cap kit for your tv model on amazon. or buy the power supply for 50.- good luck

Tampatec: vizio is one of the fastest sellers, but not the best out there, right now LG's new 3d googletv is my favorite then samsung d8000 is 2nd and sony's googletv is 3rd. , what is your fav. tv?

SwollenMaggot: Guys, before you start buying crap, unplug the power from the back of the tv and wait for about 5-10 minutes. This worked for me! Just a tip before spending your money.

Ilovetopaiseyoujesus: Hi ! HOW TO FIX VIZIO TV 55 in NO POWER REPAIR ?

ghanemyazen: ya his right get one it will help you alot

misscookksey: My vizio will come on but it just randomly shuts off!! If I unplug it & plug it back in, it comes back on for like 5 minutes & goes back off?! Any ideas of what may be wrong?!

Mani Toketa: I have a Vizio e370va that started to randomly turn off, it became more frequent and then turned off and would not turn back on. Any suggestions would be greatly appreciated.

SylentCommando: I like sony bravia's myself, And Samsung TV's those are my top 2 brands.

Ih8youlube: Not so much a fix as a diagnosis.........

Tampatec: sorry i don't do that but some companies on my tampatec.blogspot do fix boards. try this unplug inverter board then turn on tv, do you get audio and very dark video?

Tampatec: i added a link in the video description below the video i hope one of those numbers help you, i think its power-supply or maybe main board. only buy boards with a warranty. 8^)

Godzilladeathmatch: my vizio is an vo420e...lastnight while I was watching it it popped real loud and lost power...on my serial tag sticker I can't find the manufacture date..where did you find yours at?...plus do you know what could be causing it too have no power?...powerboard maybe?...thanks..p.s. I bought it in 2010...

Tampatec: i think that is still covered by vizio cause it was common flaw on some vizio models - Vizio-Phone: 1-877-698-4946, press 1 or 0 for live rep. good luck 8^)

Tim Dockery: Always enjoy your vids! Thanks for sharing your knowledge!

MANJOE46: hey guys i have a vizio 32" the electronic eye wont work. i have turn on the tv but not with the remote. I have 3 vizio in my house the remotes do work all other set but not this one. can you help me. thanks

UTWR4NGL3R: My vizio wont turn on at all. Not even the standby lights come on. I was watching it and it just turned off and I havent been able to get it on since. There was not pop, smell, or anything it just wont take power. Is it possibly the fuse?

SRtWeNtytUrBo faSt: the hard reset worked 4 me once maybe i will ty again

Jeffrey Wooten: how to program radioshack universal to Sanyo

AlexMurilloh23: That's odd, I just called in and the rep told me that they wont replace it. any other tips man? I'm at a loss here with this TV. Thanks a lot or the responses!

Tampatec: No problem, i sometimes fix tv.s for my friends and family for free, Just thought i'll share it to whomever may find it useful maybe helpful...

Coryhughes00: Hey bro i have the same tv with the same burn in the same spot. I bought it to repair and keep or sell. Were you able to find schematics for this board? Im replacing all the burnt components and would love a schematic due to the burn on the board. Also my slave and master boards both had popped caps with this burn like yours. Any feedback would be awesome

AlexMurilloh23: Do you think this will be covered after the 1 year warranty? As in a recalled model? I've read online that it could be the main board and certain people were able to ship them out to 3rd party repair men to remedy the issue. Ill give the customer support a shot though but if any recommendations, that would help. Thanks a lot bud!
