Why is my Tv screen split in half?

This is Ash from Ash Healmypc99 bringing you another repair tip. Warning! This is a mainly a Diagnosis video and temporary quick fix tip only. Apologies for not including the actual repair video as I wasn’t planning to upload this to YouTube when I filmed this. Hopefully someone may still find this useful as I give some tips at the end of the video. If you want to see how I managed to temporarily fix the half black screen problem, from this to this then stay tuned.

This is how I fixed it! I used a few of the same food stick that you saw in the video, cut them into a few pieces to fit under the ribbon cable which was causing the contact image. I also secured them in place with some Blu Tack so that if there was any pressure applied onto the ribbon cable it would no longer distort the image.

Immediately, I did not replace the frame nor bezels as I wanted to see how much of a fix it was. After around a week or so it did not show any sign of half black screen. So I put everything back together, frames, bezels.

However after that it occasionally caused some half black screen. When that happened I just pressed around the frame where I knew the problem was, it would haphazardly return to a clear full picture. However over the next 3 weeks the problem would come back more frequently and each time would require more pressure applied.

This became very annoying and finally I gave up and bought a new TV. I did some research and found out that this problem is very common indeed and many others have ended up replacing their TV. A long term repair is not advisable in most cases due to the high cost of replacing any of the troublesome parts.

In conclusion there is a rant coming up! Manufactures of electrical components, especially at the budget end, are using more and more cheap components included in their build. Some say they are deliberately including a fixed term component which will die within a specific time frame, usually within the usual period.

Since I've been repairing a few electronics this has become quite clear over the years. I've seen many products fail the day after the warranty was over. While I am not directly accusing LG or any other company for that matter, I am advising each and every one of you to “expect” cheap end products to fail within a short lifetime, depending on your luck. For some electronics it might be worth considering getting extended warranty, you need to weigh the cost of repairing versus the cost of buying a new one.

Hope I was able to help you at least diagnose your problem and also offer some future helpful buying tips.

This is Ash from HealMyTech & I need your help. I recently suffered a STROKE (end July 2021) which has left me disabled for now (temporarily?), which may have been caused by the VACCINE ASTRA ZENECA. The videos were uploaded on my channel end August 2021. I have set up a GoFundMe, any donations are welcome.

This video really helped out. Thank you. I’m dealing with two random color halves on my Samsung. Now I don’t feel so bad. Makes me miss my tube tv that still worked when I gave it away. Had it for 10 years.

Ive been fixing tvs for about 30 years and the flat panel tvs are such pieces of crap im about to give up and stick to vintage gear repair. Power supply cap replacement pays ok but led replacement is major surgery and unless you change them all, it might be back during your repair warranty period. Cost prohibitive. It seems no manufacturer has more than one year of faith in their sets, and sometimes replacement boards are no longer available, even after only a few years. The only people making money in tv repair are the courriers and the parts dealers. Extended warranty is now greatly encouraged. AND KEEP YOUR RECIEPT!!!! Sound systems seem to have turned into a pile of crap too. Best wishes brother.

I am electronics technician and repair TVs and have to comment that some of the stuff people write and comment are like WTF.... call the manufacturer with some of your questions and stop asking people to "guide" you on repairs, this gentleman is showing how to address this issue in particular. These are not toasters, they are digital devices with switch mode power supplies.

Great video- it inspired to take on my 55" Samsung which had this exact symptom. I isolated the problem to one of the same ribbon cables you showed, but in my case it wasn't a matter of mechanical deformation, but rather heat. That chip or whatever it is inside the ribbon cable gets pretty hot (too hot to touch) and I tried blowing canned air on it- not touching the cable, just blowing cool air over or under it. Every time the flickering stopped, then resumed after a minute or two as the cable warmed up again. It sounds wacky but I think the bumps on the inside of the metal frame are intended to gently touch the cable and conduct away some of the heat.

Only one cable seemed to be affected, so I took some aluminum adhesive tape and doubled it up under the cable to act as a spring, and added a couple of layers to the inside of the metal frame to improve contact- and I only did the offending cable. I left the others alone! (If it ain't broke...) With the frame reinstalled the flickering seems to have gone away.

Thanks for posting the video- it may have saved me a bundle!

Thank you for posting. This was also our TV's problem.

[j.partition]

Thanks for the info. I applied some pressure to the areas you pointed out and dropped the tv a few times from a few inches up and everything seems to be in order now.

[maledatek]

Good video. Thanks. You covered a lot there 👍🏾

[CB]

Yes you're right they do use cheap parts in everything these days, including car parts. There is a term for this i forgot that.

[zecle]

so if there's an earthquake you can't watch anything lol

[jimphillips]

i cant see a ribbon cable in this video is it bellow the circuit board? Is it the cable or circuit board at the top at fault???

Hey I got 2 problems
I just bought the Sony Inzone m9 4K monitor and have already 2 problems.
1. Screen goes half black when I start a game on ps5.

2. Screen goes black for 10 sec and comes back but all colors are grey .

The screen goes normal when i switch the HDMI slot from 1 to 2 and going back to 1
Or when I plug out the HDMI cable and plug it in back.

I don’t know exactly what I did but my Dynex tv which had the same problem is now working. I opened it after unplugging and brushed off all the dust accumulated throughout the 9 years I’ve had it. I tightened the screws on the metal piece which covers the board inside the top of the tv and that was it. It’s been good for over 24hrs so far.

I have a Sharp 80” LC-80LE632U that has half of the screen has a great shadow over the entire right side. I can barely see an image below it. If you know what part this is or how to fix it I would appreciate it. Matt

[adrianh]

Thank for your help was able to get out to going

[mickschiavone]

I have a bush 49" smart, I put the stand back on, and the screws were to long. I have angel wings and a split screen. what do you think? still have a picture, half is like 3d and the other side normal.
thank you in advance. mick

[Aimz]

Mine randomly did that today but I have a similar problem- mine is shadowed on one side, i can still see the image but its like theres a shadow on it. I'll give it a tap (i'm not taking it apart) and see what happens.

[ModernNaturopathy]

Hi..I have same problem but bottom half horizontal stripe...on LCD 22 inches LG TV..can be solved easily??

[akemikochan]

I noticed this with my sharp tv. We used to push the tv on the left side and it would correct itself but eventually did not. I thought that perhaps I fixed it when I cleaned the display ribbons and reinserted them thinking this was the issue. It worked fine, but the issue has come back and it appears to come back after the tv is in use for many hours which makes me to believe it is an overheating issue. When I unplug the tv and leave it alone for several hours, you can hear the tv crack inside as if the components are all readjusting and changing shape. When I turn the tv back on, I have to push a little here and there on the screen and it corrects itself. It also makes me to believe it is due to the hdmi component parts on that side of the tv.

[fergex]

i tried this but the only thing that makes it show again was my finger. any idea what i can use to hold out atleast a few months till i get a new one?
