To re-flow a BGA (Ball Grid Array) chip, first, remove the existing solder using a soldering iron or a hot air rework station. Then, apply solder paste to the pads on the PCB and position the BGA chip correctly. Use a reflow oven or a hot air tool to heat the assembly, allowing the solder to melt and form connections between the BGA balls and the PCB pads. Finally, let it cool down to solidify the solder joints.
Reballing a ball grid array circuitboard is a delicate operation. Typically, a hot air gun is used to melt the existing solder and the individual components are carefully removed. Any damaged or defective components are repaired or replaced and the old solder is cleaned off. For a ball grid array, new solder balls are then placed into the proper configuration for the board, and the components carefully soldered into place.
It varies depending on the design. In general above 60 degrees C is unhealthy for a CPU, or about 45 for BGA chips.
The matrix of a BGA is the pattern in which the solder balls are laid out in.
The chip package that resembles a pincushion is known as a "ball grid array" (BGA). In a BGA, the integrated circuit is mounted on a substrate with small solder balls arranged in a grid pattern on the underside, similar to the pins on a pincushion. This design allows for efficient heat dissipation and improved electrical performance. BGAs are commonly used in modern electronic devices due to their compact size and reliability.
Reflow ovens are used to create circuit boards and other electronics. They are used mainly for reflow soldering for the surface mount type of electronic components.
Yes. This is something called BGA reball. You couldn't replace the card if you wanted, its attached to the motherboard. You can do it with a heatgun, a BGA stencil and solder balls. This is not how its professionally done, and is somewhat difficult and can damage other parts of the motherboard. Professional/industrial BGA mounting and reball is done with infrared heat and ovens. The chip itself is not bad. Its in fact the actual connection or "solder balls" that crack and go bad along with the underfill which is supposed to glue the chip to the board, but instead warps it. You could replace the chip with something that has the same pinout such as a g96 core, that would certainly be interesting to see what happens.

Maybe the sync button is damaged. Its best to just buy a new one.
A ball grid array (BGA) is a type of surface-mount packaging used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors.
BGA Rework machines are used for welding. They are often used in the repairs of gaming systems and cell phones. There are many available for sale on various websites such as Ali Express. They have many brands to choose from with prices varying. Amazon and eBay have BGA Rework machines available for sale also.
Reflow Soldering information can be found at a variety of sources. You can start with going to the your local library to find information about it. You can also check out stores or craftsman who specialize in it.
If the problem is exacerbated by heat then it's mostly likely that the BGA graphics chip is losing integrity. This can only be solved by a replacement motherboard, and should be covered under the warranty as long as you do not open the xbox's case. Try using it on a different screen just to make sure it's the xbox at fault.
