2600 games look & sound crystal clear on my 7800 but 7800 games have audio and visual problems

[treismac]

I just bought both a ferrite bead and a gold A/V cord to root out rf interference from my new 7800. The result is that my 2600 games look amazing on my 7800, however when I play an actual 7800 game the system randomly emits a sustained audio buzz and the picture blurs every so slightly. What the heck? Obviously this goes beyond cable A/V cable problems and external rf interference. Is this a common or universal problem? Is this likely a "fixable" problem? Would an A/V mod rate of success be a toss up at best or a sure fire success or failure?

I am, however, very pleased with how great my 2600 games sound and look.

EDIT:

Hmmm... 2600 games still receive interference, just not as much as their 7800 counterpart.

well considering it does it more with 7800 games than 2600 games and 7800 games tax the system more with the better graphics and better sound i imagine its related to the load put on the system overall.
with that in mind i imagine its a capacitor problem and the added load on the system with 7800 games aggervates the problem.

If you look up on wikipedia you'll find the Capacitor Plague (http://en.wikipedia.org/wiki/Capacitor_plague), this is something that happened at the turn of the century but something similar happened earlier in the 80's and affected alot of companies trying to cut costs with parts because the affected caps had a flaw in them. It wasnt as well known because the late 80's and early 90's didnt rely as much on electronics as we do now.

same basic idea, a plan gets stolen, theres a flaw in the plan and it gets produced any way with the flaw in mass numbers and it takes time to run the stockpiles down . Of course they arent going to take a loss and not sell them.

it was about that time Atari was having problems and were all about cutting costs on both releases of the 7800 so it wouldnt suprise me if there are some bad caps.
keep in mind though the capacitor issue from the mid 80's to early 90's wasnt as sevre as the ones in 2000-2003, their lives were shortened but they would still last longer than 3 years unlike the ones more recently.


and even if they werent bad caps....they are still 25 years old

25 years is long enough for them to dry up. Replace them and see if anything improves, at the very least you've eliminated one possibility.
