atari2atari Posted January 25, 2012 Share Posted January 25, 2012 Greetings, fellow 8-BITers! I have been enjoying my ATARI 400 for some time, but recently I noticed that the red LED that usually is lit when the power is on no longer works! I'm no stranger to the soldering iron, and I spent some time looking around the 'ternets for any clues on what type of LED this is, and how to replace it, but have had no luck! Can anyone point me in the right direction? Also, is a failing power-LED a sign of something else going wrong? THANKS! -a2a Quote Link to comment Share on other sites More sharing options...
+bob1200xl Posted January 25, 2012 Share Posted January 25, 2012 LEDs pretty much never burn out, but I see bad solder joints on them often (had one yesterday...). Try just re-soldering the leads. Bob 1 Quote Link to comment Share on other sites More sharing options...

I am going to get into the unit this weekend; I will try resoldering the LED to the board. I appreciate the response! -a2a Quote Link to comment Share on other sites More sharing options...
+bob1200xl Posted January 25, 2012 Share Posted January 25, 2012 As long as you will be in there, get a spare LED. Just about any normal (not hi-powered) LED will work. Look very closely at the leads inside the plastic - you will see that they different up at the die. Just orient the new LED like the old one and you should be OK.

I will grab a potential replacement from Radio Shack, just in case. I was thinking that a blue or classic orange might be a nice replacement, if needs be, but, yes, I will try resoldering first and see if that fixes it. http://www.radioshack.com/product/index.jsp?productId=12611320 - - orange "diffused" could be nice and fit in with the ATARI colors http://www.radioshack.com/product/index.jsp?productId=2062572 - - and, green has a certain appeal http://www.radioshack.com/product/index.jsp?productId=2102850 - - or, "classic" blue (is it me, or does EVERYthing nowadays have blue LEDs??) -a2a Quote Link to comment Share on other sites More sharing options...
+bob1200xl Posted January 25, 2012 Share Posted January 25, 2012 Well, be careful. The Blue LED looks like a hi-powered device and ypu listed 3mm and 5mm sizes. Look at the specs and stick with something less than, maybe, 20ma? Bob 1 Quote Link to comment Share on other sites More sharing options...
atari2atari Posted January 25, 2012 Author Share Posted January 25, 2012 Good call - - I'll carefully measure the mm on the lamp width, and I appreciate the advice on keeping it less than 20ma! I'll have to go poke around in-person at the 'Shack after taking the shell off the 400 and examining the LED. Wouldn't want leads that were too short, either . . . ! -a2a Quote Link to comment Share on other sites More sharing options...
