No sound or video

post #1 of 14
Thread Starter 
A buddy gave me his old broken 360 to try to fix and use. It did display video and sound at first albeit pretty lousy until it went out completely. I tried the right trigger +y idea to no avail as well as three different sets of av cords - two of them are known good cables. It boots up normally and does not display any errors or red lights. I've read a lot of different solutions, some that conflict with one another's advice as most of the posts were pretty old. I'm more than willing to replace the x clamps with screws, nylon washers and new paste if that's the solution. I'm not to crazy about overheating it or throwing it in the oven but I will do it if you guys still think these are still viable options today.

The only "good" way to fix it is to reflow the chips. Anything else is temporary.

This worked for me for a few months on a gifted-to-me Xbox.

Irrelevant to the problem at hand. No error lights are present.

Bad chip solder doesn't noticeably degrade the experience. The 360 works one day, then is 100% broken the next day. Degrading video leads my first suggestion to be to swap out the video cable. If you are running the composite cables that came with it, then order a cheap VGA or component cable off Amazon/Monoprice. If it is new enough to have HDMI on it, then use whatever video port you aren't already using. Using HDMI? Then plug in a component cable to the analog AV output instead. If none of this works, then you likely have a bent video pin or an AV port that got bent and hit to hard so it broke some solder points. See if putting pressure from multiple angles on the AV plug give you a picture for a second.

I've already tried 3 different AV cords when it was "working" each one worked. Two of these cords are well known functioning parts. I didn't wiggle test the AV jack. I can try that.

EDIT: The reason why I tried all the cords was to 1) not have a flakey picture and 2) actually get 1920*1080 resolution

Oh and this is the original 360 without HDMI.

By 3 AV cords do you mean composite, component and VGA? Or just 3 different component ones? I can imagine a broken jack line on component-green or common ground causing such issues, which may or may not transfer to broken VGA as well.

Being a non-HDMI 360, it is 5.5 years old at the youngest. That's a respectable life for any piece of CE. smile.gif

Yes, I tried the M$ cord with the red/white/yellow, the M$ cord with red/yellow/white/green/blue, and the aftermarket cord with the PC input and the white/red. All of these worked but the video quality was not 1080 until I used the PC cord. The colors were crappy on all of them. This is a launch console from 2005. I'm just messing with it for a project and as a console for my girlfriend to hook up Kinect and work out to. Screw it. I'm just going to throw it in the oven, new paste, 5mm by 10mm screws, spring washers, steel washers and nylon washers. If it doesn't work I don't care. lol smile.gif

Trust me, no video/bad colors is an indicator of the GPU beginning to lose it's connectivity to the board, AKA RROD on it's way.

2 hours at 200* in the oven.eek.gif The board wrapped in foil with the underside fully exposed, the top only had the gpu, cpu and memory chips exposed. 8 bolts, some metal and nylon washers and its a success. This was a fun project. I wouldn't mind fixing a whole bunch of these!

Nice! Let me know how long it lasts. I "fixed" one, but didn't use the oven. Only lasted about 3 months.

Did you do both the cpu and gpu? If so, maybe you could give it the oven treatment! smile.gif

Did it leave any odor or any foul-ness?
