Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.

I would say that you have a shorted component or board, that would explain the shutdown and failure to sustain voltages.

Check whether the component E994 might be open - a service bulletin was issued on that for this model.

Or try obtaining a service manual:

http://www.servicemanuals.net/ServiceManual/HITACHI/50UX58B/593340/detail.aspx

for a paper service manual copy, or

http://www.servicemanuals.net/ServiceManual/HITACHI/50UX58B/445015/detail.aspx

for a downloadable copy.

Those manuals ought to save you a considerable amount in components bought and tried for the problem. Their troubleshooting table should direct what the problem is and what to test for in some detail.
