I have a 2022 d40f-j09 it keeps dimming in and out

I have a D55u -D1 that has a pulsating glow on top left side to about middle of screen. I was told led strips but could it be video card?

Another C21 replacement and repair here... THANK YOU SIR!

I believe my sound bar is a little bit newer. However I just opened it and it appears to be almost the same.

Where did you source your foam?

I wish u showed the before an after connection test on the wifi on the ps4

Thank you for making this, I followed your instructions exactly and got it done in like 10 minutes, worked flawlessly and even see a big improvement on wifi signal

Guessing it was a loose wire.

I took it part checked the capacitors and they were fine put it back to gather and it started working .

Great! What do I need to do if I add a sub-woofer to my 2.1 setup?

I can’t find the part for a v755-j04 anyone know where I can get one?

Okay my dude , 2 years later you still saving Vizios lol. I stumbled on this video after 3 days shopping around for a new one after mine died last week so decided to give this a shot. First time ever soldering (shit had to buy a new gun after melting my first on the first try ) and after I did this and put it altogether, all I expected was still a dead bar but ALAS the little light was on and the thing works flawlessly. So thank you for saving me $500 on a new one. 🎉🎉🎉🎉

Mine is just like yours except it's upper left. Could this be the and issue?

Can you provide new links for the items as these are no longer valid?

Thanks man, shame they tell you to dump it over a ten cent part.. you got mine working again.

I have random black spots/large black splotches randomly appearing all over screen. Once TV warms up it stops. Do you think this fix would help me?

How do you repair cracks in the black exterior of a big case (other than paint it)?

thank you for taking the time to make this video!! i have a vizio 70 inch v705h3 and have a slightly dark lower half as seen in another video but this may be the fix for me🙏🏽🙏🏽 i'll be shopping for a new led board hoping that fixes the problem. not looking forward to replacing the strips lol also a LED board for $30 vs $600 for a new 70inch is a no brainer

can't believe it worked. the c-21 capacitor on my board was not bulged at all. ordered few capacitors from amazon. figured i would at least give it a try. my soldering is basic but was able to change out neatly. did not even have to add solder. came out clean and nice. held my breath when i turned it on. works great. thanks for video

I went ahead and replaced the other 16V 470uF cap as I saw it could cause problems in different video. Works good as new. Thanks for the video!

Thank you so much, replacing the capacitor brought my sound bar back to life as well - thank you!

Add for the triangle, try to rotate each speaker in a 30 degree angle towards your triangle and ears. This helps to avoid side wall reflections and also some phasing issues!

Thanks for the video. My Vizio S4251w-B4 has been turning off for a few years and just recently died. Just something to keep in mind. These are electrolytic capacitors which means they have positive and negative polarity. Remember to put the new one in the same way as the old one. In this case negative is the gray, -, arrow mark toward the edge of the board as seen at 3:06. The shaded side on the board, seen at 4:30, is negative. They can explode if put in backwards.

Is that external antenna better then getting the same internal antenna?

~ YOU just saved me HUNDREDS of $$$ !!!! ~ I replaced C21 and C22 with these $10 parts from Amazon: [Replacement for 6 pcs Panasonic FM Series Capacitors 25V 470uf Low Impedance] Amazing You have my sincere thanks m8 \m/

I have a vizio with no LED and no sound there's picture when I put a flash light to the screen what can be the issue some have said LEDs themselves and others had said main board is there any info is greatly appreciated

This was so helpful! I just finished this and mine now works like a boss!!! Thank you!

why cant i save the sample of pink noise??

Anything for android

I have been looking for videos because I couldn't find any information on how to dial those settings on the back of the speakers and right of the bat. He says those are useless 😂😂😂😂

You sir just saved me a couple hundred bucks!! Called Vizio and was told to recycle the sound bar and buy a new one. Now after $0.50 for the 470 uf 16v capacitor and thanks to my BTech prof for the basic soldering skills, capacitor has been replaced and my soundbar is alive again! Thank you!!

My older Vizio soundbar started to leave all the LEDs on or flickering and then no sound. The sound will cut in and out.

I think the issue with it keeps blowing the caps it's a bad resistor. Just repaired mine a few days and if it happens again, I'm going to replace resistors.

I have a model V555-H1 When I turn it on. I get the white statusvLED in the bottom right hand corner comes onbthen fades off. The screen stays black the entire time. I have already replaced the main board, the power board and the LED driver board all 3 have been replaced. But I still have the same issue with the black screen. It does appear that the LED back lights are coming on. Because I can see the white LED's through the holes in the back. But I still get no picture. Any suggestions?

And what about upper left, middle right and bottom left quadrant? Those quadrants are flashing. I’ve replaced power board and main board. Could it be a bad backlights?

Amazing! Thank you))

Replaced C21 and C22 with some cheap replacements off Amazon and it works now - thanks for the useful guide! For good measure, after removing the capacitors I hooked them up to an LCR meter. C21 came back measuring 350uF with a dissipation factor of 0.2, and C22 came back measuring 400uF with a dissipation factor of 0.07 (lower is better, for those curious). Not sure if C22 was shot or just a low quality part, but C21 definitely needed replaced. Neither capacitor looked bloated, but they needed removed from the board in order to measure capacitance anyway. Hope this helps others!

This fix recently worked for me. However, there is a high pitched squeal audible(when the soundbar is on and the volume is low or on, it's not very loud). I was thinking this might be the sound of the capacitors? Is it possible this pre emptive of the capacitor giving out? Anyone else notice or have this issue?

FIXED MINE!!! THANK YOU!!! Can't believe that a blown out sound bar was caused by a $1 part! I ended up replacing both the C21 and C22 capacitors. Thanks again for a very informative KZfaq Video!!

Thank you for this.

Thank you for sharing your research which is way above my pay grade. Did as you outlined and worked like a charm. Would have been a shame to recycle at local Best Buy for such a minor repair. Much appreciated!

Perfect video!!! Thank you!

I think your confusing people where the actual antenna was located. Which I believe is in the front. So your rerouting it to come out the side near the back ? Right? People always skip shit on KZfaq diy vids

You sir are a genius. It worked like a charm!!! It was a last ditch effort before this thing was heading to a dumpster, and just like that, it is alive again. I was a bit concerned when i saw the capacitor was a bit fatter than what I got from amazon, but rating is the same so all good in the end.

Doesn't look right to me...speakers are too front and too high....front to sides at ear level. Just seen the set up and clicked away. Not worth my viewing time.

My screen kinda flickers and its the left bottom and upper also the right top corner is all dark the only thing thats not dark but seems dim is my bottim right corner but the flicker kind of makes me wonder if thats a board problem not a led issue what do u think i have a e65-1 vizio

I have a different vizio soundbar but the same issue. How do i find the capacitor online? C93 is written next to it. Ive been to multiple sites with a pic of it but they say i need more info.

Great info! I had already downloaded this app. My daw has pink noise built in I will use that. I couldn’t find before I watched your video the c and slow modes. I now know where they are. Thanks!

What did your sound bar do when the capacitor went out did the power light flash on then turn off?

Where did you order the part from?
