adam4435435 Posted September 24, 2019 Report Share Posted September 24, 2019 (edited) Im having issues after installing the modchip. The chip lights up, boots, then system turns off, it does this twice, then the red green flash. No video input on screen. With chip removed from pin header the system boots normally. The DO wire was solidered to the mother board 6th pin on bottom and the chip is bridged to always be on. I did the exact same on a 1.0V Xbox and it works flawless. Not sure why this wont work, This xbox is made in china but i dont think its a 1.6 due to the date. It has a newer philips drive and newer seagate HDD. Please help!!!

SS_Dave Posted September 25, 2019 Report Share Posted September 25, 2019 It's a version 1.1 Xbox you have there. Why not flash the TSOP? Quote Link to comment Share on other sites More sharing options...
M0RPH10U5 Posted September 25, 2019 Report Share Posted September 25, 2019 Try soldering the d0 wire to the d0 test point on the bottom of the board and see if that helps. Quote Link to comment Share on other sites More sharing options...

He could but when it has 0 ohm's (dead Short) between the top and bottem point I can't see it making any differance. Quote Link to comment Share on other sites More sharing options...
adam4435435 Posted September 25, 2019 Author Report Share Posted September 25, 2019 the blue wire is solidered to the d0 in the pic below and then to the top of the mod chip Quote Link to comment Share on other sites More sharing options...
adam4435435 Posted September 25, 2019 Author Report Share Posted September 25, 2019 i also hot swaped the chip with my 1.0 box and used evox to re-flash it just incase there was a bad bios. Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted September 25, 2019 Report Share Posted September 25, 2019 MORPH10U5 is talking about the d0 point on the mod chip not the main pcb. Can you post a pic of the solder work for the 12pin header to pcb.? Quote Link to comment Share on other sites More sharing options...
nikeymikey Posted September 25, 2019 Report Share Posted September 25, 2019 I installed one of these the other day and I just connected d0 to ground instead of the chip. Works perfectly. Hell if you really wanna do it on the quick and easy, if you have thin enough wire you can poke it in the d0 hole and hot glue it in place and then put the other end of the wire into one of the motherboard screw holes and put a screw in. I know this works cos I did a temp install once doing exactly that. Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted September 25, 2019 Report Share Posted September 25, 2019 I suspect it a solder problem not the D0 If the D0 point was not grounding it would boot the the original bios Quote Link to comment Share on other sites More sharing options...

M0RPH10U5 Posted September 25, 2019 Report Share Posted September 25, 2019 Chip seems to be in order, I'd try to reflow the solder on the lpc pins with some flux, and try again. Quote Link to comment Share on other sites More sharing options...
M0RPH10U5 Posted September 25, 2019 Report Share Posted September 25, 2019 Also, it's hard to tell in the last pic cause it's kinda blurry, but is bt tied to the ground pad in the group of 3 pads that would have been used for contrast control if it was LCD compatible? If so, is there extra wire going past the ground? Cause to me it looks like wire might be going to the 5v pad above the ground pad, I'd make sure that it's not touching the 5v pad.

SS_Dave Posted September 25, 2019 Report Share Posted September 25, 2019 Hi adam4435435 You need to resolder the header pins add some flux and reheat each conection The top right and the 2nd from the bottom amd the bottom right have to much solder Quote Link to comment Share on other sites More sharing options...
adam4435435 Posted September 26, 2019 Author Report Share Posted September 26, 2019 Thank you for your help!!!! SS_Dave you were absolutely correct ! I resoldered the Pins for the pin header with some better Solder and its works perfect!!! Thank you again!!! Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted September 26, 2019 Report Share Posted September 26, 2019 Awesome. Thanks for reporting back that you got it sorted SS_Dave Quote Link to comment Share on other sites More sharing options...
c0tt0nm0ufh Posted September 27, 2019 Report Share Posted September 27, 2019 Little late to the party but I also recommend soldering d0 to ground and NOT the modchip. Plus that way you don't have that messy cable coming out the front. Quote Link to comment Share on other sites More sharing options...
