ppj34 Posted March 13, 2021 Share Posted March 13, 2021 (edited) Hello I have a problem with my atari 800 xl (NTSC Revision A2 version) with a UAV card installed on it for 3 years. Everything was working fine ... until yesterday. I wanted to start it (without having touched anything in the cables or anything else ...) and I no longer have an image on the screen (same TV as before), just a variable signal of color bars with constant audio noise. I have the impression that a component may have failed. I have no cartridge or some peripheral component connected. I opened the machine, the card is clean, no visible burnt or broken component. Do you think it would be one of the chemical capacitors in the video part that died? Thanks for your interest. 20210313_142544.mp4 Edited March 13, 2021 by ppj34 1 Quote Link to comment Share on other sites More sharing options...
_The Doctor__ Posted March 13, 2021 Share Posted March 13, 2021 don't turn it on again... what does your power supply look like and what voltage is it putting out.... 1 Quote Link to comment Share on other sites More sharing options...
ppj34 Posted March 14, 2021 Author Share Posted March 14, 2021 here is a photo of the power supply... (it is the original one delivered with the computer) Do you think it could come from power supply ? Quote Link to comment Share on other sites More sharing options...
TGB1718 Posted March 14, 2021 Share Posted March 14, 2021 This is the photo of an Ingot PSU, yours looks like the same case, but the label is different, maybe someone can confirm if the Ingot has different labels Quote Link to comment Share on other sites More sharing options...

I would not use that PSU until I verified the voltage, and even then I’d be looking for a replacement ASAP. In the meantime, it sounds like one of your chips may have been damaged. Once you have a safe PSU, see if any of the chips get hot, especially memory. That’s likely your culprit. Quote Link to comment Share on other sites More sharing options...
_The Doctor__ Posted March 14, 2021 Share Posted March 14, 2021 (edited) Looks like a UK/EU power supply... maybe some of those folks have a thought... I've hear conflicting stories about if they are the same as the US ingot death supply, @flashjazzcat might have some thoughts about the power supply as he's over there. I'd give all of the chips including the UAV a press down, I can't tell you how many upgrades wiggle up from sockets during transport, moving, and storage. It's one of the reason I'm constantly saying these things need a method of support, being secured... even if it's a bloody zip tie.... If you have a dmm test the power supply under load. 5.2V 5.3 Volts would be normal (as far as METER readings today go)... I don't like anything above that. It' for certain any crazy voltage like 6,7, 13 whatever and you've got damaged chips... Edited March 14, 2021 by _The Doctor__ Quote Link to comment Share on other sites More sharing options...

archeocomp Posted March 14, 2021 Share Posted March 14, 2021 Yeah ingot killed many Ataris also in Europe. XL series were more robust. There is a hope only one or two DRAMs have been killed in this 800XL Quote Link to comment Share on other sites More sharing options...

My father had an 800XL that suddenly died back in the 90's, I thought then it may have been the PSU that caused it, he gave it to me, but I never found the time to fix it (I had 2 130XE's at the time), so I ended up throwing it in the trash ( I know, should never have done that), today I just regret doing throwing it, would be so easy to fix and I would then have an XL to add to my collection.

ppj34 Posted March 15, 2021 Author Share Posted March 15, 2021 Hello, Thanks for your all replies. So I measured the output voltages of the power supply plug. I get a measurement of 7V, which seems too much. According to what I understood, I should have 5V. So, my atari is probably dead. I'll try to find another power supply to test it, but I don't believe it at all ? Thanks for your help. Quote Link to comment Share on other sites More sharing options...
_The Doctor__ Posted March 15, 2021 Share Posted March 15, 2021 when you get another power supply you will probably have a couple of dead ram chip, and a dead uav... that's where I'd start. normally it won't cost much to fix... you might have to replace one of the large scale chips if you kept turning it on.. it's the luck of the draw with this sometimes. It still won't cost much to fix though. Quote Link to comment Share on other sites More sharing options...
ppj34 Posted March 16, 2021 Author Share Posted March 16, 2021 (edited) Hello, I just found an official atari 800 power supply (the same type) that I had somewhere. I first tested the outputs with a multimeter to make sure it provides 5V... When I turned on the atari with it, well, it works in front of my amazed eyes ! I could not believe it. Well, I think like you that some components have probably been weakened. I just bought some rams in anticipation to change them if necessary. Thanks. Atari will survive! ?

If it’s the same type as the one that failed, don’t use it! Those PSU’s are ticking time bombs. Get a new power supply and just leave the Atari alone until you get it. 2 Quote Link to comment Share on other sites More sharing options...

Take the plug off the bad one and attach it to either a usb or any good 5 v ddc power supply. Quote Link to comment Share on other sites More sharing options...

_The Doctor__ Posted March 16, 2021 Share Posted March 16, 2021 5 Volt D.C. 2+ A is a good idea. Low ripple, no buck. Quote Link to comment Share on other sites More sharing options...

ppj34 Posted April 23, 2021 Author Share Posted April 23, 2021 (edited) Okay. I bought a new DIN - USB 5V cable and it works fine. The atari does not seem to have suffered... Thanks for your help.

Panther Posted May 20, 2021 Share Posted May 20, 2021 Here's a good Atari Ingot power supply... 1 Quote Link to comment Share on other sites More sharing options...
Sugarland Posted May 20, 2021 Share Posted May 20, 2021 Glad to hear it's working again! I wonder how many of these old PSU's are left plugged in 24/7 by people. I hope they don't cause a fire. Quote Link to comment Share on other sites More sharing options...
