Yes ; however, bear in mind that 0.6mm pitch is decidedly not industry standard, and the 0.8mm motherboard connection makes an off the shelf flex cable impossible.


SoWhat material do you use to set the path of the lcd pines for your ribbons?

So I was wondering if it's a possibility to replace the original Vb display flex cable, with a regular or flex cable one if so how many pines would it be and the pitch or spacing of the conductors.
The reason behind this mine it's pretty dangle for all the

Good job! I'm glad to hear that patch worked a charm.

It does look like it could be a display problem.. If you're good at fine soldering you could try soldering your ribbon cable in place of where that glue is holding on the display piece. You have to 'scrape' a bit of the insulated coating off the ribbon cable on that end.


Thanks
What kind of tools do I need?
Which other alternative are there a?

vb burn out

Hello guys

Iím new VB owner
And I fried iit
It started smelling like burn plastic no smoke although
Thatís the short story

The long story is
I got VB that was having a bad contact with ac adapter and the tap
I realize this bad contact wheI slightly plug the ac adapter from the input so,it work for a while
I also tried the tap in another vb and didnít work
So I follow this guide https://gbatemp.net/threads/tutorial-v ... ut-ac-adapter-set.465122/
Alll the steps
And you guess it when press power ,it starting to smell burn
So my question is do the whole motherboard burn out? If so how can I check this?
Or just the voltage regulator
I also believe the controller burn out

Thanks in advance for any input
Btw, if this canít be salvage at least it could serve as a warning
