In this video I show you how to fix the EV100 distortion or gray line problem. The problem is caused by an internal ac coupling capacitor which should be of a higher value to decouple any dc voltage offset from the video signal. While some people report a gray line plus some distortions I was seeing a black spot on the left plus some distortions.
I used a 220uF B sized tantalum capacitor and it worked great. But you can use anything above 100uF, electrolytic, ceramic, tantalum, whatever you have around. The voltage rating doesn’t matter as much, anything above 3V is good.
Something like an electrolytic might be easier to solder because of the longer leads that can be bent into the required spot, it’s really up to you what type of capacitor to use in this fix. There is enough room inside to fit any type of capacitor.
