LOL, what a twisted triangle. We have the original seller and now the buyer checking in in these last two posts. I'm not intending on taking sides, but I'll be curious to find out what the solution is. For the record, my TED never crashed in my Turbo Grafx, but I also never tested the Air Zonk ROM so I don't know *shrugs*

I *think* the romset I downloaded was indicated to be Everdrive friendly-- not that means anything at the end of the day since people make mistakes and a bad rom may not have been discovered.

I am a layman but would a bad ROM cause garbled graphics (and still run)? In my experience,  ROMs immediately lock up and never really run. I'm also not sure why he would get inconsistent results with running the ROM. Could still point to a hardware failure with the TED I guess,  but that still brings me back to the point of how I didn't have issue with my TG.

Indeed, as I've told you in our emails back and forth I never had a problem with the system locking up.  I used original HuCards and not a TED since I recently got that.  When I opened the system to mod it, there were no leaky or blown caps.  Perhaps the TED is just drawing too much power from the system making it overheat/lock up ?  I know that I tapped in to the +5 from the card slot for the region mod chip.  Maybe before attempting to re-cap the system and charge you for his work, LaC can tap in to the power from the regulator instead of from the card slot to see if perhaps that fixes the issue.

Well bad caps don't always leak AFAIK (my Game Gear experience definitely tells me this, at least for GG systems )but I'll bow out of this conversation since I'm not the most experienced person in technical matters like this.

Caps can be an issue, but I expect not this time
Most flash carts (not sure on TED) use 3.3V flash chips
They don't drive the bus as well
This is rarely an issue, but will cause what you described

Wait... this thing is locking up or acting stupid when using a Turbo EverDrive with roms, but from the sound of it does NOT do so with actual HuCARD games? 

Funny thing is, I have never had issues with my EverDrive.  I use a rom set that I went through and divided up by region/hacks/translations, and have never once had the TE lock up my system.  However, others have had issues with roms they had, that did just that.  Fixing it was as easy as directing them to my set. 

I guess the system should be tested with a real Huey to see what it does.  Then just go from there.

Well said Bernie.  I never had an issue with this system when using it with real hucards never did test it with a TED (since I barely got it).  Friend of sonic said he played the system when he got it for like 15 mins with a TED and didn't see any problems.  I when I got my TED I tried some old roms I had for years on my pc and most didn't work so I when to the isozone and for their set and everything worked fine.  So please have LaC 1.  Use a regular hucards, 2.  Try tapping power from the 7805 for the region mod switch and 3. Get a well known working rom set for the TED and have him report back..

Can we make arrangements for me to get that ROM set or at least the ROM for Air Zonk so I can get it over to LaC? I'll send you a PM or if for some reason I can't,  my email is my user name on this site @gmail.com

OGHUGO, you still sold me a system with terrible jail bars which since have been greatly alleviated,  so I'm not sure where I lie on your claims of testing it. Maybe it is my ROMset, maybe not. Hope it's the former.

Friend of Sonic, never said you lied..  sorry if you thought I meant that..  I did not meant that what so ever.  Just don't know if you relayed that info to LaC..  Also I took pics, and I did not have jailbars using an XRGB mini connected through HDMI on a 50 inch plasma.  You have a PVM..  So I guess that is totally different.   I think I did ask you to try to view this on a different screen..  like a scaler or converter.  But you saw I sent you pics and they did not show jailbars..
Here is the pics I sent Sonic if you guys would like to check them out and see if you guys can see any jailbars in the images.

I don't see any
Please note than cables and even cable routing can cause them

If it could be a thermal issue I would try press testing and/or cold spray on the QFPs after it fails.
