Hisense H58AE6100UK - discolouration and slow load on right side of display

[djmka]

Hello.
I have a Hisense 58" 4K television which has a strange issue whereby the right half of the screen takes slightly longer to load an image than the left. It also has discolouration and horizontal blocks. I've attached images of the colour problem and blocking but do not know how to attach a video of the lagging. Can anyone please advise me how to upload a video? Many thanks

Could this be a faulty TCON? Or could it be a faulty ribbon cable going to the panel?

Ribbons don't just go faulty. Possibly the tcon or a component on one of the driver boards.
You need to take the back off for testing/checking.

Thanks diif. Are you able to tell me what to check on the driver board and how to do it, please?

One other thing - the ribbons have an arrow on one end. Should it point up or down? Do they have a right and wrong way?

Post decent photos, an arrow would suggest a direction.
It's hard to tell what the problem is with the poor source photos.

Hope these images better show the problems I'm having.

firmware...

Re: Hisense H58AE6100UK - discolouration and slow load on right side of display

Would firmware affect only one side of a TCon?

Re: Hisense H58AE6100UK - discolouration and slow load on right side of display

any Issue at MFC driver section lead the screen refresh / discharge fault.

Re: Hisense H58AE6100UK - discolouration and slow load on right side of display

So do you suggest buying a replacement TCON?

Re: Hisense H58AE6100UK - discolouration and slow load on right side of display

start with log in service menu clear chip (hard reset ) if didn't help try downgrade firmware.. or search hisense france if they have issued this fault with flashing only mfc.bin driver

Thanks Diah. Would you know how I can get into the Service Menu by any chance? I guess there's some magic key sequence on the remote control that I need to press.

Re: Hisense H58AE6100UK - discolouration and slow load on right side of display

open the normal Menu and go to Sound ---- Advanced Audio Settings .. Scroll down and highlight the Balance slider, make sure it is on 0 -- Enter 1969 on your remote -- green "M" will appear at the top left.. hit menu to open service menu.

Thank you. I managed to access the Service menu but could not find the “Clean chip” option. I have attached a picture of the menu. Please advise. Thanks.

djmka unfortunately you are wasting time with these procedures , the fault is clearly the panel, exactly the gate drivers (side cofs), there is a very huge duscussion with me and another user called Ancient1, started last december, i don't think you have to annoy yourself with all the reading, i tell you it ended removing the side cofs of one side , so the first step to do is to disconnect one ribbon tcon>panel at a time and see which side is the worst visualizing..

Update -
I have removed the bezel to expose the 6 side cofs. At least two of them looks to be damaged (probably happened whist removing the bezel a month or so ago to fit new backlights).
If I move the first one the colours go back to normal. The same happens when I move the other, more damaged one.
Are you (Davi.p) saying that removing the damaged cofs will (may) fix the issue? If so, do I cut them as close to the panel as possible or should I leave a certain amount?

yes those are toast, remove all on THAT SIDE ONLY, slowly peel it away from the glass, if you go slowly it should all come off pretty easily, bound to be some videos on youtube that you can check if you like.
