Sourav. I don’t know exactly why you are saying “no” to @Ermos . He does not say that his experience is identical but similar.
I hope that you read the entire link that he posted which continues:
That seems very similar to what is happening in your case. So maybe the timing isn’t exactly identical and he saw lines, you saw dots. However as well as sound ceasing you both found the display providing random images not information.
Although the precise cause of the issue is not discussed I think that the relevant point is that he needed to contact his dealer and had the Rossini replaced. I cannot predict whether the same thing will need to happen in your case but you should prepare yourself for this eventuality or the need for a replacement part being fitted.
