Hi guys, Currently trying to troubleshoot my video issues. Can someone check my vtx settings to make sure its not a configuration problem. Here are my gear list 

• A01 25-200mW 5.8G VTX - https://betafpv.com/products/a01-25-200mw-5-8g-vtx
  
• F405 4S 20A Toothpick Brushless Flight Controller V5 BLHeli_S (ICM42688) https://betafpv.com/collections/brushles...s-icm42688
  
•  CADDXFPV Ratel2 Analog Camera https://caddxfpv.com/collections/analog-...1500493923
  I have checked all Wires for continuity. Note this is a new cam but old vtx. I was only able to get video when I connected the battery to the FC and adjusted the battery cable in a ver specific position after that I was not able to get it back. 

Here are some pics

You want to wire from cam to FC. Then from FC to VTX. How you have it wired does not pass the camera feed to the FC, hence the gray screen.

so try out the yellow vtx cable from the camera pin directly to the vtx pad on fc ?

Your wiring is correct. On that VTX the camera is connected directly to the VTX with pads provided to route the camera out to the FC for OSD processing and then back to the VTX.

Taking a closer look at your FC I see what looks to be a dislodged capacitor which could be the root cause of your problem...

yikes great eye ! Adding some light solder should do the trick ?

That might have been it. I was unable to capasitor back. is there any comparable FC board that you might recommend comparable to this one ?

I don't have any particular recommendations, but it's no secret that I'm not a fan of BetaFPV products, so I would say anything other than something manufactured by them  But at the end of the day it's up to you. If you want a straight swap-over without having to re-route any wiring then just get the same again, being extra careful not to slip with your soldering iron tip when soldering to any pads that have miniscule components close to them.

Below are some links to a selection of 25x25 AIO FC's. Make sure whatever you get supports the LiPo voltage you are intending to use. If you need something with more than 2 UARTs then stay away from any F411 FCs:
