Glasses screen with letters “V”?

Good morning everyone, I bought an F4 V-6 and when I pass the image through it, the image comes out with a lot of letters “VVVVV” in Oculos, I already exchanged the camera for another model, but the letters “V” appears after going through the dish.

Can someone help me?

Behind the plate, the solder bridge was made between the VCC and the RAM
I’ve done the test without solder and with the solder and the problem continues
