Here the other day, a tree crashed into my ET160, and the top plate broke, the camera was pushed in to the FC/PDB stack and all the nylon standoffs broke as well as the Flight controller. After rebuilding the quad and moved everything over to a grasshopper 160 frame, I noticed I get a lot of black lines on the video feed when flying. It increases with throttle, so I would assume this is Electrical noise. I changed my ESC from LB20A pro to Racerstar 20A blheliS (this was because I wanted to try the blheliS ESCs) and the black lines are still therel, but not as radical as with the LB20A.

My setup is:

MXK PDB with OSD from banggood (one of the few MXK PDBs that has actually worked for more than 5 batteries) with 2 pc 25V 470uF low ESR capacitors on the power lines.
Foxeer HS1177 camera connected to 12V on the PDB
Eachine ET200R VTX connected to 12V on the PDB


Can this be the camera, the VTX or the PDB? My guess is the PDB, but I would rather not swap out the PDB if the cause could be something else.

My first guess would be the PDB as well, but, if you have another FPV cam and VTX you could try them first one at a time and then both together.. still say it is the PDB, The MXK are notoriously unreliable PDB's...I learnt a long time ago and only use good quality PDB's. sure you pay more, but have far less hassles with them.
