Tore the screen ribbopn on my fiurst and the cause of the others downfall.

Basically the charger port failed so swapped it with a few others and still faulty.

Finally got one to work by toggling the charger and got greedy; I wanted to test my old one but the screen wouldn't come on and now the screen has totally died, I think.

WHAT COULD BE THE PROBLEM AND WHERE'S THE CHEAPEST PLACE I could source a screen ?.
