Pink striped screen due to heating

[AlbertoA]

Hello everyone, I am new, so if I get something wrong I kindly invite you to point it out to me

My problem is this: I use to use my a6300 for livestreams through Elgato CamLink and dummy battery. It happens right away that after quite minimal use (20 min max), pink stripes appear on the screen and then in live which I believe is due to the camera overheating. I have tried to remedy this by opening all the flaps, changing dummy battery and buying a metal cage to see if the heat dissipates better. No luck. Do you have any solutions? I read before I bought the camera that it was one of the best quality-price solutions for livestreaming use but as it is I am a bit incapacitated. I hope for your bright advice. I thank you.

Pink stripes??? I'm not sure what you mean exactly.

Sometimes you can get flickering bands caused by low budget LED lights.

Can you link or refer to a sample video so that we can see what you mean?
