i cannot get rid of the interference in the video on this 1.1v and i have tried everything!

bulkchart32 · June 19

i recapped the entire foxlink psu with rubycon caps of the exact uf needed. i also purchased a delta psu to see if the different brand would change anything and it did not. i recapped the entire motherboard except for about 5 of the 22uf caps. i used rubycon on everything except the five in front of the processors. i used 5 nichicon polymer caps there. i soldered a wire to each screw hole of the psu and soldered one wire to the metal outer shell and one to a screw hole on the motherboard(to make sure it was all grounded well). i also recently tried disconnecting the power cables from the dvd drive and harddrive to see if those caused any issues. there was no change. i have an open xenuim chip on it and on a 1.6v. i also have the same bioses on both(evo and cerbios). the 1.6 has a perfectly clear and crisp pic. it is flawless when i boot with cerbios. but i just cannot get rid of the interference on the 1.1v. i'm using the xedusa+ hdmi adapter. i have already tried exchanging it for another one and have the exact same problem. i also have the official microsoft hd pack and have tried it and still get interference on it. about the only thing that does not give me interference is a monster xbox hd cable but, i do not like the color display when i use that cable. the interference on the xedusa is usually in the form of diagonal or vertical lines that run across the screen during 480p output. 720p and 1080i seem to be fine. any and all tips and help is appreciated! even a good educated guess would be appreciated! oh, and i also have the same problems with unmodified 1.0 xboxs.

Can you post some photos of the board, please? There's probably something causing interference on the analog side of the video circuit.

these are pics from before i did a lot of work on it. but i was still having the same symptoms back then. just to be clear, the 3 caps close together in the upper left corner, i took the one polymer cap back out and replaced all 3 with rubycon zlh caps.

Did you replace this surface-mount electrolytic near the AV port as well as the through-hole cap near the hole? Then clean this area of the board thoroughly with alcohol and a clean toothbrush?

i have replaced them. it made no difference. i have not cleaned it yet. i'm waiting till i get the system to function correctly before i clean all the flux off and and close the system up for a while.
