I have a cheap android tablet with a busted screen. Replacement screens cost more than a new tablet and I hate to waste it since it's only a few weeks old. I took it apart and it runs on a Allwinner A13 ARM chip. The LCD section of the data sheet doesn't seem all that helpful. Is there any way to get a VGA output from the chip? I see the chip has LCD pins for vsync and hsync but I'm lost after that. Is this a reasonable project to take up or should I just throw it out?

  • \$\begingroup\$ I guess you'd have to (re)write a significant part of the software to get VGA output, and you will very likely need information that is not freely available. In other words: a waste of your time. But did you check wide enough for a replacement? Last year my son dropped his shiny new Galaxy (S3?). I got a replacement LCD/touch for ~ $20 and repaired it. \$\endgroup\$ Jan 15, 2014 at 14:52

To make my comment an answer: I would advise you to throw it out. A $100 phone might have been worth the replacement parts and repair effort, but not a $35 phone.
