Fix A Flat Screen TV With No Picture - Vizio Has Sound and Backlights But No Picture - T Con Board

It's a sad day when you TV stops working properly. Your heart sinks because you know they are difficult to repair and expensive to replace. Most TV repair shops closed down several years ago due to the high cost of repairs. TVs have become disposable technology to most people. However, they really aren't all that hard to repair and it costs much less than you think! This video walks you through how to replace a common issue on Vizio and a few other brands of TV.
I use www.shopjimmy.com to order replacement parts for my TV. They did not sponsor this video in any way and I paid full price for the part I ordered. I've used them several times and their customer service is top notch.

[@Chi-Town-Meechie]

Thank you so much!!! My 60" vizio was doing this exact same thing. Got a T-con board online for $20 and it worked. Saved me almost a $1000! 😎

[@TightWadDIY]

That’s great! I’m glad it worked for you!

[@jayjay-pw2lp]

I have a Sceptre 50 inch also with no picture, I checked the back lights, they are working, it has sound, and a glow, going to order a T-con board today. Thank you so much for this video.

[@lloydz666]

Cheers bro I think you just saved me buying a new tv and the part is only $50 thanks bro 🙌

[@polkadotz666]

Good instructions thanks. This might be the repair needed for one of my two Vizio's crashing in the same two weeks. I'll explain both situations and hopefully you can share your thoughts on diagnosis. TV. #1, Backlight certainly works but losing color, contrast and brightness as the picture is starting to blacken out in top left corner and bottom right...almost is rectangle shape. Picture is good after a rested restart and the problem quickly creeps back in. TV. #2, our oldest Vizio maybe 8 years, 50". First sign of a problem was the quick App start brand bottoms at the bottom of the modern FireStick would change the TV input to an unused port. Next problem it would blackout and flicker back on with clear white horizontal lines. Then it flickered until it don't come back. After long rests it worked again a couple times, with sound, and was back out within 10 minutes. Now it's out-out with no sound of the FireStick clicks changing the Apps and all black screen...no backlight. With was a 2 month experience from beginning to end.

[@wewa8088]

Great video Very easy to follow with only one mistake, when you replace a TCon Board one should wait to remove the screws until after the cables are unhooked to avoid having to hold down plate not only making this easier but less amount of times hands are on the device the better. It's odd your replacement order is right, and you even note your reason for doing so which made it odd when you didn't when you removed it.

[@dropaitemahabirsingh8277]

Impressive that was easy to fix.i have that problem with mine

[@xman666soad]

Happened to me 5-6 years ago. I kept the tv for over a year just sitting there because I had only used it a handful of times, eventually I went on Google figured out I could buy a PCB and it could fix it. So I replaced it and voila.

[@TightWadDIY]

Nice work! 👊🏼

Thx hope to receive my new TV soon but maybe I can still fix this one and have a spare

Just replaced tcon on my Vizio. Still have backlight and sound. No picture. I’m pissed.

[@TightWadDIY]

TVs are tricky. You might want to sell it on FB marketplace for parts and move on.

[@kenrickeason]

I'm having the same problem.. I bought 3 T-Cons boards and it still glows..

[@TomMartinek]

How did you know it was the T Con that needed to be replaced? Mine turns on, but I can't select a source or any menu items. After about 5 minutes a screen saver image shows up so I know it's not anything to do with the actual LED Display. I was thinking I needed to replace the main board, but then I came across this video. It's the first time I've heard of the T Con Board.

[@TightWadDIY]

Yours doesn’t sound like a tCon issue.

[@francinewade3204]

It good when you know what you're doing God bless

[@craigstern2902]

A lot of the time it's the power inverter board in this case, especially if you have sound & can see the picture just faintly when shinning a flash light at the screen without lights on in the room your TV's in..

Pretty sure I'm going through the exact same thing right now - hoping to swap the board out this weekend. Is yours still holding up since the repair?

[@TightWadDIY]

It is a crap shoot with this particular model. They are known to blow TCon boards. The new one could last a few years or it could blow immediately.

[@lucasboettcher7010]

Yeah I heard there’s issues with the panel drivers burning out the t-con. Who knows, maybe I’ll get lucky. Is yours still working or did yours burn out again?

Hi. Thanks for taking the mystery out of the repair. I have a Vizio p602uib3 Flat screen TV. The screen starts out black then goes all white in 30 - 40 seconds and the audio works. What is the board that I need, where do I get it, and what is the cost. Alan

my TV was on overnight for two days and I try to watch a movie & my TV started to turn different colors on the screen .

Interesting.

[@HWD919]

Hey man I wanted to ask I have a Vizio e65 f1 and it’s doing something similar to what yours is. Is there a way to test before I buy? The flashlight trick didn’t work for me

[@c0smo263]

If you have a multimeter you should be able to check continuity throughout the backlight, or check between connections on the board. The latter would require schematics or knowing which circuits are where.

[@stitcher4729]

You're not a tightwad fixing a big TV like that. If I tried to fix the 20 inch-er I just threw out that would be tightwadding. Subscribed to see what else you can do!

There is sound and I can tell that the the grey lines shift if I press buttons on the remote control. The TV turns on and off. Just a crap picture. I have the VIZIO "v585-h11" and every replacement part I checked has a price well over $100.00. For a few dollars more than "spare parts", I bought a new TV with warranty. Now I am going to tinker with the old TV and see if any fuses or capacitors are blown and replace them. Maybe I'll snip a few diodes as a last resort.
