I got this a few days ago, and these were already broken. Don't know what they're called but them being broken is causing Black lines in the screen while the rest works fine. They're attached to the screen but I have no clue how to fix them or if I can. None of these cables are okay besides 1, theres 6 in total. Please help

Hi @salmab

It is very difficult to fix them and is not really a DIY repair.

The cables are attached directly to the screen itself and the connections are very fragile. You could end up damaging the screen if you apply too much heat or pressure when trying to solder them on.

The cable itself is a FFC type cable (flat flexible cable) but you would have to know the specifications to know which one to get:

pitch, which is how wide each wire is and how far apart they are from each other as there are lots of different sizes e.g. 0.500 mm, 0.625 mm, 0.635 mm, 0.800 mm, 1.00 mm, 1.25 mm, 1.27 mm, 2.00 mm, 2.54 mm, but the most common pitches are 0.500 mm, 1.00 mm, and 1.25 mm.

number of wires in the cable.

As you can see the wires are very small and very close to each other so attaching each wire to their respective point on the screen won't be easy.

Usually most repairers write off the TV as faulty screen as replacement panels are also hard to find. If you do find one (search for the model number on the back of the panel itself - not the TV model number) don't be surprised that it will cost nearly half as much as a new TV.

An option to consider is to advertise the TV as faulty screen- good for parts to try and recoup some of the cost towards a new TV. Working TV boards are always in demand.

You can’t, the equipment and training needed to fix it costs more than the screen.

Just get a new screen.
