唔小心撞裂了連住display panel這條線, 就可能係display冇顯示的主因.
如要銲駁返 opened 線s , 可用 30a ...

請問30 Watts 電銲會否過熱

yes, too hot for this kind of assembly !   a 15~20watt would be fine.

pin 1 - 0.01

refer to the readings , 冇左 12v, 肯定冇野睇 。
其他pin位 readings又好似低左D,  to be verified.....可能係掃描訊號。
有冇去淘寶找新的可用cable？？？？
師兄您有冇 hot knife (我冇)？睇番broken condition (as photo) , 可用它刮走flex cable 表面絕緣層, 然後飛線修理。

有去淘寶找上次賣25pin flexible cable 賣家, 佢沒有flexible display cable.

師兄, 小弟沒有 hot knife.

正是 !
銲不難， 難在 remove the insulation layer without damaging the links。
