Would any one know where I might get a HP #LCD 693499-004 which is a lcd screen for a HP 18-1550 All in One Computer? I would need it for $50. My upstairs neighbor ran into her desk with her power wheelchair and the face of the computer landed on something causing a circler break in the screen.

Temporary solder in 100uF 10V low ESR cap in parallel with C102 to see if it solves the problem, but make sure the power supply caps are OK first.
KEMET Polymer Tantalum caps can be used.
Why regular electrolytic capacitor with low ESR wont work/last here?

They used 47uf 10V SMD Solid Tantalum cap which has low ESR and also does not dry out and deteriorate with times like typical lytics cap, it also smaller than lytics cap with the same value.
