I have a 4GB xbox360 slim with unlocking LT 3.0 I was using frequently. But two days ago. it presented a different locking (screen freeze) I thought it was the CD that was scratched. but the problem persisted by locking even on the main screen of the xbox. I opened it and made a careful cleaning. I used to check the solder of the chip (which was normal) Now comes the weird part, after that I played for hours, and I still spent the night watching netflix on the console with no problem. I thought I had solved the problem, but today it has stopped again and frozen the screen. Or other times, it only beeps a few times and even goes off by itself. I tested my sources of energy and I even connected a stabilizer but it did not solve the problem. Today I saw a tutorial on the internet that solved the problem of the whistles by using the FLET cable that connects the sensor. (I passed an insulation tape to avoid contact with the aluminum part) So far he has not presented the problem again. but I'll come back here to see. I would like to know if anyone else has gone through something similar ??? I'm praying it's not the BGA or the unlock chip. or internal memory.
as promised, I came back here to tell you how the tests were. good I spent the last few days using xbox more often and exchanging several games. no problem was repeated. I want to add that if any of you had the same problem in the future please check the following: 1 dust on the sensor (excess cleaning product or even humidity can cause failure) 2 plug the FLAT cable with the front plate (it may be during the cleaning process to fit it not very well) 3 - contact of the flash cable with the aluminum part (which was my case solved with grinding tape)
