Hello community .
I recently bought a used xbox360 after I tested that It worked , the owner told me that I had installed a Mod-chip so I opened it carefully to check if it can be removed . Anyway I found no mod-chip but after I reassembled it , I plugged in the HDMI but seems nothing to happen . When the xbox360 is powered-off the TV display only a message box that writes no"NO SIGNAL" but when I power on the message disappears like it found a signal but still black screen .
Solution i have tried
1. To replace the PSU
2. To replace the HDMI
3. Changed the AVI and HDMI cables from an functional xbox360 slim
4. To plug in a HDD in case the xbox just need to have it's SATA connected somewhere
5. Power it on from the remote - controller and used combinations to reset the display
I am afraid if it is broken CPU or motherboard
Do you have any suggestions?
