Re: SONY 65" 4K - Horizontal Line on top

I will, thanks for the advise. Hoping that someone know which pins to block of on the ribbons once I get them. Myself and pazoline would highly appreciate it.

i am looking for the datasheet of the t-con board , we canot destroy our ribon cables again, they are really fragile , if somebody just could help us analyzing the tcon ! would be of great help!

I notice that nowadays people asks for tech advice, they receive them and for some reason they start for their own road, maybe i am distracted, but who told to you about the cut off method? I am able to find the signals on tcon's but i find this not the solution. If the horizontal lines goes totally black and steady for all the width there's no solution for them, if them are moving there no burnt circuit to block. No dialog here, i will quit eventually..

Tomorrow , i will do the following , i will use the damaged flat cables to test the isolation techinique , seeing the pictures of your tv , that is exactly same as mine , i came to conclusion that the problem can be by passed isolating the clock signals on the conector apointed on the image that i atached on this post

I'm still waiting on the new ribbons. Hope this works as this is such a beautiful TV.

Re: SONY 65" 4K - Horizontal Line on top

you will likely be successful as your ribbons have "severe" problems. There could be other underlying conditions but those can be investigated once the ribbons have been address. Ensure the new ones are seated correctly AND ensure that the connectors / seats are clean and cleared of any old "debris" from the other cabling.

I have found a video where horiz. sparse lines, but intermittent, can be solved via signals masking..
