Help please xbox video is all messed up!!

So I Turn on my xbox and the sceen shows xbmc but it is rapidly flashing like the tracking is off on the vcr the screen just keeps rolling on screen after screen all of my games i can make out still work and are still displayed but i cant play any of them because its too hard to see with all the flashing going on its really frustrating ive replaced the power supply thinkling that was the problem but its obviously not that so im asking for anyones help ive spent way too much money for this xbox to be thrown away.. please any suggestios would be great I first thought it was maybe the cables but thats not it either because they all work just fine on my regular xbox. please help me!

 

if you haven't changed any of the Video carrier settings in XBMC (NTSC/PAL) then it could be the video chip on the MOBO.

i agree, i would try some different video settings on your Xbox
first. It could just be that somehow they got set differently.
Plus fooling with those will not cost you more $$$

 

i belive it is the video chip because i dident mess with any of the settings but how do i change or fix the video chip or is that possible??

 

time for a new box.

kc

 

so theres no way around that?? so can i put the chip dvd drive and hardrive in a different xbox and will it work properly?? i would have done that by now but i cant solder the ground wire way to hard for me any suggestions?? thankyou

 

with the modchip you will be able to do that with no problems.

you might also try formatting the harddrive and reloading your XBMC and try it before you do any swapping, that'll defiantly rule out it being a software issue.

ok thanks yea i tryed formatting the software and it did no use but yea thankyou now i know its not completly garbage

 

You need to find a 50/60 hz tv... It is in the settings.. usually somewhere in the system settings (i never use xbmc as a dash because it's just too touchy) is an enable 50 or 60 hz setting. Whatever one it is set to is wrong..as it's a permanant setting reinstalling everything won't make a bit of difference. It will save itself across a reformat. The GPU doesn't fail in this way...

 

so get a different TV? i hope thats all that the problem is umm i need more information please janrocks. So how do i know wheather the TV is 50 or 60 hz?? sorry im not to highly educated on electronics but this problem is bugging me terribly im so frustrated because it worked fine now all the sudden bam its all screwed up but if u know more about this problem please inform me all you can! Thank You SOOO much i will check my T.Vs at home today and see if i have a 50 or a 60 thanks

 

the GPU (an nVidia NV2A @ 233Mhz) can most certainly get out of calibration (deterioration of silicone polymers causes changes in resistance/capacitance/impedance) and drift in frame rate causing the exact described output this user has described.

also formatting the harddrive and doing a new install WILL correct any software issues, an XBOX does not have any form of OS it simply has a BIOS (which isn't programmable via software on the harddrive or DVD drive) and everything (including settings) come from the encoded executable .xbe files. the GPU and the CPU share the only writable memory and it's 64 meg of RAM that all data is lost from when power is removed/turned off.

kc

 

umm kinda confused with all of that so what do i do??

 

format the harddrive, reinstall your original C/E drive (you should have backed those up when you modded the box the first time) and then reinstall your XBMC. if the problem was in your software (XBMC) then it will now be fixed.

kc

 

i cant re format anything because my screen is all flashy an stuff is there anyother way i can re format it?

 

when you first turn the box on if your video is all scrambled during the flubber it's the GPU otherwise it should still boot an AIDeluxe disc and allow you to format the drive and FTP back the original files.

kc

 

I know this is dumb, but I have fixed two boxes with the exact same prob. You need to dl enigmah's video switcher disk, burn it and cold boot it. Then hold "A" and restart (if you are PAL hold B). It might fix the damn thing.

 

well as soon as i turn on xbox it starts flashing from moment i turn it on i tried the AID disk and it loaded fine but it was all flashy to But theking07 you say you have hyad this problem umm im not the best at electronics and understanding your terms if you could simplify it and tell me step by step that would save my life lol for i have been pulling my hair out for a good 2 months on this same problem its driving me crazy please and thankyou for your information so far

 

when you load AID can you make out the screen enough to tell what it says next to 'Video' at the bottom left?? is it PAL or NTSC?

enigmah's video switcher is a program to swap the carrier signal on the box.

kc

 

i cant quite make it out its so flickery

 

you can give the enigmah's a try then, i find it highly unlikely that you've swapped the carrier unless you were playing with said program to start with.
