e200 v1 blue ring lights up, but no screen. Memory chip does work.

I’ve read several other threads about the blue ring of death and there are numerous methods to try to fix it.  I’ve tried a couple of methods, format, battery, hard reset, updating firmware.  I was wondering if anyone can pinpoint me to the correct solution.  When I turn the sansa on, only the blue ring lights up.  I have another sansa so I put the memory chip in the other sansa and it worked fine so the problem is not with the chip.  Does anyone know what solution will work if any?  Thank you

You may have to resort to the e200tool via Linux referenced in the Blue Ring Of Death thread.
