Hi, I have a HDTV model TH-50PC77U and blinks 7times.
As I researched, it means "SC Floating Voltage SOS" and it could be caused by SC, SU, SD, D or P board failure.
I found a Troubleshooting book for TH-50PZ ([url]http://www.scribd.com/doc/46124232/Technical-Guide-Troubleshooting-Handbook-GPH11DU-Chasisbut[/url]) but no luck for my model.

Can anyone give me tips?

Thank you.https://Hi, I have a HDTV model TH-5..., D or P board
