Hi everyone, new to the forum but looks like it's the right place for me to visit. I have an Xbox 1.6b (2005, Australian 240V model). Tonight it wouldn't fire up at all, completely dead and unresponsive to the power button. I opened it up and there was no obvious damage on the mobo. All i could measure on the 20 pin molex from the psu were some very low voltage (0.6V) on the 5V pins. 12V was reading 0. Ac input fuses showed good continuity. The only thing that looks suspect on the psu is the component in R10. I measured across the pins for R10 and its reading open circuit. I reflowed the solder on the AC input pins, no change. The xbox has been moldded since purchase but has been working perfectly until tonight. Nothing has been changed in the last 15 years. Still in original case. The original power cable seems to be intermittent now but other cables tried and no change. Any suggestions to help diagnose would be appreciated as I couldn't t find any replacement psu online anymore. OG psu is Tuscany rev 1.0. Tyia, tssfka
