3 reboots and frag

[ChriZz]

As mentioned in the title. The xbox restarts 3 times and flashes green and red alternately the third time. The so-called ask. Which can mean anything.

 

The console came from something like eBay and the seller wanted to throw it in the trash because he couldn't fix it. I bought it anyway because it's a crystal.

 

I've been looking for a long time. No capacitors were broken and all voltages were correct. Then I noticed that the lpc was being fried quite badly.

 

After removing the solder from the LPC, I measured it again and there was about 1.5 volts missing at pin 1...or it switched off again very quickly. The same thing happened before the mcpx on the 3.3 volt pad.

 

Well, long story short. I remembered a post by kaos engeneer. On the LPC (pin4) where the 2 vias are, a reset signal is passed along. And it was precisely this track that was torn down by the previous owner. That's why the console couldn't start and switched off the above-mentioned voltages.

 

I repaired this track and everything is back to normal. Maybe it will help someone.

whats up with that broken trace? Does it connects to the other side?

The track was torn off by the previous owner...the reset signal is sent over it. I scratched the track free and soldered it with Kynar wire. Console is working again.
