New Dudu7, touch screen not working

Dusan111

Hello
Help me a little.
Are these cables installed ok? Is one of them wrong?
What cable is data for touch? Help help.

The reset button also does not work. What cable is used for touch and reset button? 😖

Dusan111 I believe it is the white ribbon cable. It does not look fully inserted. Definitely worth lifting the cable lock and checking the cable is fully inserted.

Dusan111 The first one from the right is touch. Here you can swap the plug the other way around, nothing will happen, or check if it is pressed well.

Thank you both but i can't get touch to work.
Here are fresh photos. Cable does not go any further into socket and clamp makes it fix.
I see some kind of micro damage on the edge of first/last line. Could this be the issue?

Dusan111 The first one from the left is the touch, you have to insert the tape and tighten the safety catch, if you make a mistake and insert the tape the other way around the touch will not work

So you say that the white cable with blue colored front is for the touch? 😅

If you know for sure, can you tell me what for is border left empty connector for? And the small orange one? And the border right conector?

Earlier today you wrote that the touch is right one, now that this is the left one 😅😬. What's correct?

wybitny2

Dusan111 I don't write English well and that's why. You have to secure what is marked in the picture so that the tape holds, otherwise the touch will not work

wybitny2

Dusan111 If you connect the tape the other way round, the touch will not work either, I did that once and the touch did not work

Thank you.
I understand you. But....

The cable does not go any further in. With clamp it is insured and does not get out. But does not work.
On the board there is also another same size connector where it is labeled "TP". But is on the other side and the cable is barely long enough.
So i wonder. What connector is 101% good one? 😖

wybitny2

Dusan111 The one I marked is good. If so, report it, maybe you'll get a second screen, but I don't know how the Chinese seller will react to it. The second connector on the other side is the microphone and if there are buttons, then this is for the buttons.

Dusan111 If you have recently purchased the radio, it is better to return it than to ask for a display with a digitizer to be sent.

Hello,

I have the same issue. Can you tell us if you find a solution?

Dusan111

In my case i had bad conectors on the right copper cable. I took the scissors and magnifiing glass and cut off cca 3 mmm of cable. Now it is working ok.
Beside that I contacted the seller and got replacement cables for cca 10eur with shipping :/

Dusan111 You mean this one?

Dusan111

Yes 🙂

Ok thanks for the information I will double check mine. One last question.. the connectors should be faced down correct?

Dusan111

Some up, some down.... this one must face up 🙂
