xbox slim 4gb freezing

[cubano123]

got a 4gb slim corona v5 and when i turn on the xbox to boot to the xbox logo the screen gets scrammbled and freeezes.
I tried hdmi and av on different tvs and still same problem. I sucessfully formatted the 4gb internal memory and cleared cache and got installed on the latest dash. No hard drive installed no flashdrive either. the system is stock. Any suggestions

I recommend an XCGPU reflow.

I had similar problem. But it was caused by 4gb NAND R/W QSB. Try to desolder that and try to boot.

Course I kind of fixed my freezing box by booting it on and off for 4 hours straight... but we dont mention my bad ideas here, XD.
