spellforce7 Posted January 21 Report Share Posted January 21 i bought this xbox v1.6. it has a problem of turning on for few minutes than turns off, after that it keeps turning on for 2 seconds and than off. i opened up the xbox and immediately saw that the power supply was already worked on and whoever did it, did a very ugly job. the power supply is Delta DPSN-96DP. As seen in picture 1 the big capacitor was changed to 400v solder with wires just lying there, the glue was supposed to hold it but it was only stuck on the capacitor and not on the metal and plastic. the below 2 green caps were changed to with higher voltage. both the big and green caps were old used caps. i changed few caps. in picture 2 the caps marked green are what i changed with new and correct caps. the resistor marked red were changed or something else because their underside show sign of different solder than the original ones on board. are these resistors right? in picture 3 the glue on left looks cut off, is there supposed to be different component here or the one here is right? in picture 4 the area circled red, are these capacitors or resistor? they were either changed or lifted than put back with ugly fat soldering. anyway are these right? lastly the mainboard picture these 5 capacitor under cpu/gpu value is 3300uf 16v while online search says its 3300uf 6.3v, are they replaced too? my problem is xbox turning off after few minutes. i tested 500gb desktop hdd, 1tb laptop hdd and without hdd. 500gb desktop hdd turns on for few minutes than off by itself, after that it turns on for 2 seconds and off. have to give it rest for hours to turn it on again for few minutes and than turns off by itself again. 1tb laptop hdd takes very few tries and most of time with first try it turns on and off by itself but stays on for more minutes the 500gb desktop hdd. without hdd always turns on first try and stays on for 10-20 minutes and off by itself. So its just power supply or the main board caps problem too. Quote Link to comment Share on other sites More sharing options...
nikeymikey Posted January 22 Report Share Posted January 22 Can you post some pictures of the consoles motherboard? That will allow people to see the caps on the board as well as any other potential issues the board my have. Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted January 22 Report Share Posted January 22 I am thinking that PSU has been modded from 110v to 220v as I have seen reports that by replacing the main filter cap from a 350v to 400v was all that's needed The numbers on the 1st transformer ( Red box ) are different to the 220v one I have here.. I have also had a 1.6 PSU that had that transformer fail, I would work when cold then as it warmed up the supply would stop working. Cheers SS Dave Soft modding is like masturbating, It gets the job done but it's nothing like the real thing. 1 Quote Link to comment Share on other sites More sharing options...

Do you have a picture of the bottom of the motherboard? The other option is to look on eBay or similar for a replacement PSU, Just make sure you get one that matches your regions power and for a 1.6 console.

Any thing is possible but the 1.6 needs a 5 volt standby power and the 1.0-1.4 only has a 3.3 volt standby supply, It would be easier to convert a ATX computer supply. You would be better off getting another power supply from eBay or the like. The fault may not be the power supply but without a oscilloscope to monitor the 5 and 12 volt output's from the supply it's easier to try a replacement supply.

spellforce7 Posted January 23 Author Report Share Posted January 23 thanks for all the replys. As SS_Dave said above the power supply was modded to 220v. i just saw 120v on the back and used a step down transformer. i put back the 400v capacitor and ran it without step down transformer. now no turning itself off, the only problem is that 400v capacitor cannot be safely fit inside. i fitted it outside of the xbox like in picture, don't like it this way but its better safe here.
