Tupin Posted March 30, 2011 Share Posted March 30, 2011 My 7800 has worked fine ever since I got it three years ago, and it just stopped working. The light does not turn on when the power button is pressed. What should I look at? Quote Link to comment Share on other sites More sharing options...
Itchy Koala Posted March 30, 2011 Share Posted March 30, 2011 My educated guess would be to crack it open and check the solder points around the power jack, its possible the jack has lost connection. Quote Link to comment Share on other sites More sharing options...
Tr3vor Posted March 30, 2011 Share Posted March 30, 2011 maybe the power cable broke... Quote Link to comment Share on other sites More sharing options...
+Mitch Posted March 30, 2011 Share Posted March 30, 2011 Bad power supply or bad voltage regulator would be my two first guess's. If you have a volt-meter it should be easy to test. Mitch 1 Quote Link to comment Share on other sites More sharing options...
Underball Posted March 30, 2011 Share Posted March 30, 2011 Oxidation on the power switch. Quote Link to comment Share on other sites More sharing options...
Rex Dart Posted March 30, 2011 Share Posted March 30, 2011 I'm guessing the switch... they're not exactly crap, but they seem to be the first to go. Quote Link to comment Share on other sites More sharing options...
Underball Posted March 30, 2011 Share Posted March 30, 2011 I'm guessing the switch... they're not exactly crap, but they seem to be the first to go. yep. Try opening it up, and touch the contacts for the switch together with the end of a metal screwdriver, and see if that jolts it on. That will tell you if it's the switch or not. If not, it's probably the voltage regulator. that's attached to the little metal heatsink behind the cart slot. Unfortunately, the VR is too close to the Cart guid outer cup, and the prongs from the Voltage Regulator can get broken as they constantly get bent back and forth from carts being wiggled around in the cart slot.

Tupin Posted April 1, 2011 Author Share Posted April 1, 2011 Nothing with the switch. The voltage regulator has no legs broken. Quote Link to comment Share on other sites More sharing options...
oldjd Posted April 2, 2011 Share Posted April 2, 2011 You may want to check the plastic"rod"that depresses the power switch.I have seen them so worn down,they wont engage the power. Quote Link to comment Share on other sites More sharing options...
eddhead Posted May 24, 2011 Share Posted May 24, 2011 Hey, don't know if you ever figured it out Tupin, but if not all my money's on a faulty AC adapter. Every 7800 owner I've ever known (including myself) has had it happen to them at least once. A guy on eBay makes new 7800 AC adapters. They're reasonably priced (though they were quite a bit cheaper last time I checked) and I've had mine for over a year with no problems! eBay Auction -- Item Number: 370232403538 Good luck!!

ATARI7800fan Posted May 24, 2011 Share Posted May 24, 2011 sorry to hear that happened. Quote Link to comment Share on other sites More sharing options...
ApolloBoy Posted May 24, 2011 Share Posted May 24, 2011 Nothing with the switch. The voltage regulator has no legs broken. Voltage regulators often die because they burn out, not because they're physically broken. Do you have a multimeter? Check the output leg of the 7805 with a multimeter and see if it's putting out 5V.

Koopa64 Posted May 24, 2011 Share Posted May 24, 2011 You can get new 7805s off Mouser Electronics. I got 5 of them in case I ever need some regulated 5 volts. Quote Link to comment Share on other sites More sharing options...
