I want to fix Video door phone which works its doorbell but it is not able to display any screen.
So I disassembled its plastic case and I detached FPC film cable from LCD display in order to inspect LCD display's PCB
I measured ESR resistance of all smd capacitor on this PCB and I noticed that there is some SMD capacitor which has high ESR value(48ohm 50V 0.47uf,15 and 28 ohm 50v 3.3uf,10 and 8 ohm 35v 10uf)
I desoldered this 5 suspicious SMD capacitor like below screenshot.

But I cannot identify specification of desoldered capacitors below screenshot. What capacitor should I purchase for LCD display's PCB?
