How to properly warm up the processor on the console?

Question

Do it yourself

They gave me a smart set-top box for a TV set for repair \ experiments, which shows with interference.
At first I sinned on HDMI, but the point is in the processor - when you press the radiator, the interference disappears.
Advise the method of warming up, I also can not remove the radiator ...

Answer 1

You would at least indicate the model, and even better, attach a normal photo.
Yes, it happens that bga soldering partially falls off. Then the most correct thing would be to do reballing , but this requires equipment and a certain amount of skills. Sometimes warming up helps. Hot air gun, IR lamp, or even in the oven. But you need to understand what you are doing, or follow the instructions clearly, otherwise there is a risk of damaging neighboring elements (especially in the oven). And instructions for different devices, suddenly, differ.
