Dropped Phone, day later blank screen (no cracks)

[Queen Jeneene]

hello ive done enough browsing to give myself a headache. just wondering if there is any hope for reviving my phone.

ive taken it apart, exposing the underlying motherboard and put everything back together. thought the digitizer might have become loose. but to no avail.

the last thing i want to do is buy a new screen and lcd digitizer (whatever) if there is an easier less expensive remedy.

Thanks in advance!
