problems modding v1.6 - no video with 2.6 chip
I have a v1.6 that a friend modded. It wasn't soldered very well, so I redid the connections on the header pins. It would get the front lights and the blue led on the chip, but has no video. I pulled the rebuild circuit board off and wired the board with individual wires according to the diagrams on this site. It still has the led's on the front panel switch and on the mod chip board. I get a solid green eject button and no video. I can press the eject button and it will only flash green, but the dvd drive will not eject. When I turn the mod chip off, I get the red led on the front panel chip switch and the xbox boots into the ms dashboard.
I had another xbox that I was modding and it is a v1.0 and a 2.6 chip. It was a success, so I slaved the chip out of my problem child xbox into a known working unit and it worked. It booted to the flash bios screen as it should have. So therefore, I suspect the chip is alright. I could not try the chip out of the working xbox on the V1.6 xbox as I had already stuck it to the noise shield with the double sided tape.
Now I was frustrated, and only found similar problems on the forum with no solutions. I went and bought a brand new xbox (v1.6) and this time I did the wire install per the diagrams in this section of the forum. I did the one where you solder the 3 wires to 1 side of the resisters (or whatever the little things are) . Flipped the motherboard over and soldered the D0, lan and HD wires also. Hooked everything up and when powered on, It gets all the led's on the fron panel and chip for a few seconds and turns off, After a couple of more seconds, it powers on again and back off. It keeps on cycling like that. I still get no video. I have a green eject button when it is on each cycle. When I turn the mod chip off, it works as it should. I get video, ms dashboard and a red led on the chip switch.
I have modded about 6 xbox’s with no problems, but they were v1.0 – v1.1 and v1.2 – v1.5 units. I have obviously met my match with the v1.6
Any suggestions would be appreciated.
