Sony KD75XE9005 Bottom half double image

[Formaster]

Hi guys,

I'm tyred from these sympthom, if anyone helps me really big thx.

When i open the connection and play with these ribbon cables, i can get back the image problem free. BUT after turn off and ON, the bottom half is ghosted/doubled again. Did'nt from touch, only reboot the TV. I have changed the ribbons from the other side, but the same. Anyone any idea please?

I masked a small section from the T-CON ribbon cable. Now the picture shows without any failure, but don't know what caused the problem.

You have a problem in the panel on the SKV lines

Thx, sadly did'nt saw the picture below from this black line, before wrote the last comment. Is there any possibility to repair this?

Re: Sony KD75XE9005 Bottom half double image

No, this black line cannot be fixed.

Re: Sony KD75XE9005 Bottom half double image

Either way or panel replacement.

Made some new pictures, while the line isn't black, it is green and going not trough the whole screen. Is exactly panel issue?

After SKV amputation on the non-working side of the panel, a thin line remains on the screen.

some sets (sharp) that have a similar problem can be "saved". The "save" involves removing the tabs on the side of the panel of the "non-working side" IF the set has side driver boards / tabs along each side. You have to remove the front plastic bezel to see how the set is built... to see the tabs and driver boards. IF you are lucky, this operation may remove the black line as it is related to the tab driver on the side. CAUTION: the operation CAN NOT be reversed... that is once the tabs are removed they can not be put back so this needs to be your last resort effort. Post more pictures of the sides of the panel so that the forum can see what the design is like and provide more guidance.

Also note: some sets (newer ones) don't have side tabs / drivers external from the panel (like those pictured on the bottom edge) and they are built into the panel itself. You are unlikely to be able to save these sets with this type of failure.

Thank you, i just sold is so. This is a huge work on this big boy and the build quality make it more difficult. But it is good to know

Re: Sony KD75XE9005 Bottom half double image

Well, it's right that they sold it to him, the panel will not last long, because the panel is very large and the working (duplicating) SKV will need to power its own and non-working half of the panel, for it it will be a big load.

Re: Sony KD75XE9005 Bottom half double image

Currently, a 70 inch sharp, that had its side tabs removed, has been running daily for over 5 years so it might last longer than in its "non-failed" operational mode. :-)

Re: Sony KD75XE9005 Bottom half double image

Well, here, how lucky you are 50/50.

Re: Sony KD75XE9005 Bottom half double image

guess that's better than the zero for not trying.

Re: Sony KD75XE9005 Bottom half double image

Budwich you don't know what you are saying, Sharp of many years ago are another thing, today's screens are made with no side tabs..
Some months ago i was developing an experimental technique using mini drill and a diamond 1mm tip to make a hole in the beginning of the faulty line/gate driver.. it needs a special technique to not ruin the panel.. i succesfully find it but i have made experiments not on a tv with this fault but on a cracked screen.. i have no tv like this, very difficult to find on market.. these months i'm not repairing any more things..

Re: Sony KD75XE9005 Bottom half double image

yes... you didn't read what I said. I indicated if the set did not have any side tabs then the save is likely not possible with the "removal method" as it is not there to remove. You probably should have bought the OP tv to fix it with your "method".
