thax Posted July 6, 2015 Share Posted July 6, 2015 Hi there, whats the prob with your 1050 drive? brenski mentioned it today. cheers Quote Link to comment Share on other sites More sharing options...
Mclaneinc Posted July 7, 2015 Share Posted July 7, 2015 (edited) Give us some detail, it may be self fixable...Try your best to be as detailed as possible ie does the red led light, does it read disks but not write, does the drive just spin etc etc.. And if you know, does it have any custom stuff like a Happy enabled.. There's a lot of stunningly knowledgeable guys in here who may be able to identify the fault instantly. Does not hurt to ask...

mistapaul Posted July 7, 2015 Author Share Posted July 7, 2015 1050 powers up,Atari xl sees the drive, but the 1050 doesn't spin. Gets very hot on the heat sink at the back of the drive. capacitors or Dead drive mech? Quote Link to comment Share on other sites More sharing options...
spookt Posted July 8, 2015 Share Posted July 8, 2015 Could very well be one of the voltage regulators if the heat sink is getting really hot. Lack of one or the other voltage would mean the drive not spinning (12v? Sorry no schematics to hand and I've been out of the repair game for a year). If you have a multimeter it's easy to test for 5v and 12v on the test points on the board. Quote Link to comment Share on other sites More sharing options...

Gets very hot on the heat sink at the back of the drive. capacitors or Dead drive mech? Chances are either the 7812 regulator, the voltage doubler circuitry (one or more of the horizontal raised diodes near the large caps) or both of them are defective. The drive mech motor is a 12V type, so it makes sense this is your area of interest. The diodes are known to fail. It can't hurt to check the other diodes in that area when your at it. As said in post #8, start by checking voltages. The regulator and diodes are cheap (max 5 GBP in total), so replacing them should not break the bank. Caps do dry out after so many years, but I'd concentrate on the regulator and diodes first. The large caps can be quite expensive a few GBP each). re-atari Edited July 8, 2015 by re-atari Quote Link to comment Share on other sites More sharing options...
