This isn't my video but it's a fair representation of the fault I have, starts with slight screen flicker as the set warms up which happens every 5 seconds or so that gets more regular until more or less constant https://www.youtube.com/watch?v=Un8cAjUtOvA was thinking T-Con but open to any other ideas as seems to be quite a common fault on these

its linux tv, much like to reset all lvds and ribbon cable after cleaning them.... check if you have bad caps on psu... the last things test half dissplay to see if the flicker remain or not.. then t-con replacement -
Tested half display and fault disappears when either ribbon is pulled ie no fault if either ribbon is disconnected but is present when both ribbons connectedComment

I am facing similar issue in my Vizio M55-F0. One photo is when its not flickering and the other one shows with flicker. Is this TCON or main (power) board issue?Attached FilesComment

Update: I found a swollen 22uF cap on the video board that I replaced. This has led to reduction in the frequency in this jitter. I noticed that 4K videos on Youtube work flawlessly for almost 6 hours, however upon playing regular videos from Youtube, the jitter appears back again. This behaviours persists unless the tv is turned off for some time and then restarted.
Please let me know if you have any ideas on this.Comment

Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!
My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.
This time the original cable broke too close to the screen, it can't be fixed without tearing the screen... -
Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".
It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...07-31-2025, 08:37 PM -
Hello again everyone,
This is my latest mission, to try getting this Sony tv back to normal working order…
I've only just got it today, when you power it up everything is as should be, in fact it works perfectly for a few minutes then the screen starts getting horizontal lines on & eventually the full screen goes back, I will upload photos of the problem & also some photos of the board etc. You might notice that I'm busy trying the tape method, I'm not sure exactly where the clock lines are so I'm just guessing & hoping for the best lol . I've already tried... -
Hi,
I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on... -
