TV LED RIBBON CABLE TOO LONG
TV LED RIBBON CABLE TOO LONG
(OP)
I am struggling to find a replacement cable for an LED TV. The cable which links the T-Con board to the screen.
My cable is 80mm long.
I can find a cable which is 100mm, (20mm longer than what I need).
My question is, if I buy this cable and put two 180° folds in it to create a joggle, to shorten it by 20mm, will that impact the cables operation?
The 100mm cable is shown below.

It's unlikely that the excess length is going to be noticed. 20 mm of clock skew? From this: https://www.edn.com/rule-of-thumb-3-signal-speed-o... it appears to be 15cm/nanosecond; so you are looking at 2/15ths nanosecond => .13 nsecond. I doubt the LCD operates near that speed, but as I said, if there's a problem, replace them both.

Now the actual data rate will likely be substantially slower

I think the mechanical question is can this be fit into the space available. I looked at a couple of replacement videos and there isn't a lot of extra space in some designs. Frustrating was seeing that the placement of the T-CON board seemed arbitrary - that is if equal length cables were used, the board had room to be relocated, but the raised bosses the board sits on would not allow it. Mechanically I could work out an adapter, but what a mess it would make.
