My asus rog just died overnight with a dead battery. Tested not passing 2 mosfets at positive rail. Jumped across and found shorted rail. Schematics were not found so I started removing coils and diodes until only the video bga chip was left. Unfortunately I don’t have a bga machine so heat gun on high! Cleaned pads with solder like you teach and short went away. What is the chances I can seat a new bga with my heat gun. New chip will have solder balls. Following your other procedures of course.
Hello, sorry to hear that! Iam very sceptical on placing a new bga chip that large with only a heat gun on top. It surely needs a preheater and low temperature on top about 290. Advanced soldering skills and luck are needed. Also a holder for the top nozzle.is a must! The success probability is very low, you know every first time, is difficult. Ps:you shouldn't jump the 2 mosfets... the repair process now is very difficult..
@@AnyrepairENG when I jumped the mosfet it just shutdown the charger. That’s how I discovered the short. At first I thought it just wasn’t charging and powering up. New video is chip is half the cost of a used motherboard and local shops wants the same price to install on bga station. I had forgotten about checking the memory chips for shorts first tho. How would I check them now? Asus gl503vm.

Check for ohms on the memory coil. With the gpu on the board it should be 16-60 ohms. Then there is no short!
