Hello mates

I have here an N70 with weird display, I already tried programming via UFS, changed EMI filters for display but display shows like this.

Any ideas mates ?

Kabayan, i think the fault is not on the EMI filters, its on the display connector CODE X4401, try to replace it, and im sure it will work 99%.

my dear friend better use your tester and check all the connections from the connectors going to the drivers there must be broken or cut line connections.use the basic electronics to solve it.
