didnt work.. have any other tricks? the audio cuts on logic and audio any other place also get cut

Odd - for me and many others - disabling the pitch solved this issue. Try looking through the blog post in the comments - you might find other answers there. Most notably though, you could try making the pitch track an audio file - then bringing it in already pitch"ed" and see if that works. Hope this helps.

It would be best to avoid QLED technology. Ordinary LED turned out to be very high quality and durable. I have an LG with a 3D display. It has worked without problems for more than 10 years and I am very satisfied with the picture. ​

Толкни, когда ответят. У меня такая же проблема))

Hey Pickle-Rick!! I'm working on a similar issue. A new main board did not fix the issue. I've tested all of my LED's and they're all good. Voltages at the power board are steady, but they're abound 68 vdc. There's some info on the power board that states 129 volts for the 75" TV, but I can't find that voltage anywhere. I get the 13volts at each terminal on the power cable that I'm supposed to get. But when the ribbon cables are disconnected my Standby voltage is supposed to be 7.5v but I get 10.85v. The TV will stop cycling when either ribbon cable is disconnected, but if both are connected then it cycles again. I have a new power supply board coming, that I can return if it doesn't help. The fact that the LED's stay on and the cycle stops when only one ribbon cable is plugged in has me puzzled. I did think that perhaps the power supply board is not putting out enough current when both ribbon cables are connected, which is why I ordered the power board. Any ideas Cucumber Man?

1) disconnect one side of the screen see if you get a picture, if you don’t reconnect the screen and try the other side! 2) get a piece of clear sellotape about 1cm, and remove the lower ribbon cable on the main board and place the tape on the cable covering the top connections making sure the tape is folded over covering the brass coloured connections on the other side of the flat ribbon cable..plug it back into the main board and try it again 3) if that didn’t work, try the bottom of the ribbon same cable.. 4) repeat on the top flat ribbon if that didn’t help

@@wisher21uk Thanks! I'll try that this evening.

@@terryzak1742 just take your time don’t rush so cut the sellout about this big ---- may have to fiddle with the size of tape 😀

@@wisher21uk Thank you! The cellophane tape did the trick, and got the power to stop cycling. But even with the new main board I had purchased, there were small horizontal lines across the screen. Therefore, I put the original main board back in and cut a narrower width of tape, around 2-3mm in width. It took several trail and error attempts to keep the set from cycling, but even with the small width of tape I have the horizontal lines. My wife knows I love to learn from things like this, but she's seen me put a lot of time into it. She came over with an ad from Best Buy for an early Black Friday sale; a 75" Samsung TV new for under $600. That's pretty amazing to me. This UN75RU8000FXZA weighs 85 pounds. I don't know if this new 75-inch is as good, but I'm baffled at how they can make and sell a similar TV for $600.

U need to tape it not use new ribbons (i tried) some weird way the tape works wonders

I have a similar issue. I did everything he did but when I took out the speaker and plugged the power back in, the TV started doing that on and off thing again. I unplugged power supply and the light stayed on like his did. I plugged it back I'm and took out the speaker and instead of staying on like his did, mine went back to malfunctioning as it was. So does that mean it would be the speaker that's messed up? Or the power supply board still?

Did you say you managed to fix yours? Mine is doing the same, i have worked out its a signal issue from the chip on scrron ribbons going to the tcon board which is telling the tv to reboot but not sure how i block that signal, seen a guy in another video do but cant quite get it working

Hi. I replaced the PSU (power supply board) and that's it! The TV is working again.

@@oquefizhoje are you saying power supply board? Please clarify…need help too. Thank

@@penhchetsophorn3051 yep. I replaced the power supply board. the tv is still working.

I did replace the power supply board and problem is still there for mine. Anybody tried something else?

In newer Samsungs you've got only 1 LVDS connector and covering with a tape won't work most of the time. You have to understand the fault on the driver board and than try to fix it. Sometimes swapping the mainboard will help, but if it's a short on the display driver board, you'll have the same fault after some time. I had a customer who came back after 2 months. I'd never bet it would happen, but it did. So, either you know what you're doing, or you're guessing ;) IMHO.

Luck is made-up to believe in (just like movies and etc.) but we're all created with common sense. Just a heads up.

I do have a tv like yours,what is the problem? Unfortunately my warranty is expired!!

@@razvanu19 Faulty LCD panel, without the guarantee it would of been an economic write-off. Been fine since the repair. I wish you luck in finding a solution but I suspect it is new TV time for you.

If i get the ribbons out from t con it gets sound and stays on,and so are the back lights,but if I increase the volume it turns off and on again!! The display being completely disconnected!!

I actually tried this-- but it didn't work. I saw this ironically on a tiktok. I ended up tossing the TV and buying a new one. Had a bourbon as well to ease the pain.

Maybe I didn't try this -- reading other comments-- I think I just replaced the ribbon(s) all together. CRAZY!!! Should have tried it.

@@lancek7533 yea or give them a good cleaning. Mine works but has lines both vertical and horizontal and I haven't had time to mess with it. I too tries the tape trick didn't do much. I think mine has an issue with the mainboard. I'm going to replace it and see where I'm at after that

You are so betlog in repair of this kind of tv you should know the sequence and try to fix but it didn't work

I did end up pitching it. I bought all new parts for every piece inside -- still couldn't get it to fire up. Unfortunately.

This didn’t work for me, same issue. I pulled forth pin

Did you tape the cables ?

I’ve got the exact same tv and issue. Will be trying the tape method and checking the voltages from the psu tomorrow. Did you manage to get yours fixed?

It's the panel itself that's bad I'm having the same issues and that's what the tech told me...

Solved: indeed in the back panel and solved it with the tape trick. After a lot of trail and error found the bottom flat cable on the mainboard I had to tape pin. 15-17.

@@nl2rma, I have the sane issue and I'm terrible at this. Can you explain this in greater detail?

@@aaronowens7620 hi Aaron, if you search for "repair led panel with tape" on CZcams the first result is from a chanel called "FrugalRepair". He explained what is done as he blocks certain contacts on the flat cable leading to the led panel. The only problem is to find the right lines on the flat cable to block. On my qe75q6 it was the bottom flat cable on the motherboard and the sync lines I had to block were pin 15-17 from the right. I have a picture but cannot post this here.

I have a qn75q60 as well same issue but the tape trick didn't work on mine it stays on now but has vertical and horizontal line and I know it's missing vgh voltage I think my mainboard is shot

I saw a video that semed to solve it if it wasnt a capacitor on the mobo - there is a single pin in the cable from mobo to psu that is wonky. Newsons electronics channel - easy fix video title.

please let me know if you solved it trrashed t or what, im about to go get one with the same issue & will need to fix it thanks much

No. I replaced the board and still no tv. I think the lcd panel is burned. I was trying to find the power panel but I can’t find it on eBay.

@@lancek7533 Bummer. I have the same issue. I narrowed it down to either the Main board or the LCD (nothing looks burnt or shorted on the LCD, but I don't know how to test it. I ordered a main board today and have my fingers crossed. I had recently repaired the TV but it had a different issue, which ended up begin solved by replacing the Power board. Now I think a google chromecast shorted something out. The place where I purchased my parts was fairly inexpensive and has 20% restocking fee, in case you'd like to check if they have yours. It was called TVpartstoday. From what I've researched, and it is apparent you have as well...your power board seems fine, but you never know. Good Luck!

Angel Carreon thanks! I was only looking on EBay but now that you mention, I’ll check out the web and see what I can find. I’m not sure based on the tests in a few videos I’ve seen that it’s the power panel- but worth the $80 or $100 to try. Good luck to you too

Lance K I got the same problem and was about to buy the main board, but stop when I watched your video. Let us know if you fixed yours

@@zimyko Qe55q60rat. Same problem. Has anyone found the solution?
