Home Theater Questions? Ask a Technician for Answers ASAP
Hi Chuck and welcome to JustAnswer,
Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, have you tried if it will do a RESET?
I understand and the above post is the only easy doable attempt hence....
Have you checked / tried RESET p.8 ?
Can you please try viewing HERE ?
Sorry to hear of this Chuck and if so, then as you posted, internal to the circuitry; i.e. flashing. With no firmware source and the challenge of getting hold of a one-time-use flashing jig, then no possible course of action.
Of course a possibility would be a failed peripheral circuit component to the EEPROM. Are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter and even a soldering iron?
...even if just exploratory?
Again I understand Chuck.
My participation is strictly limited to technical, repair and/or installation issues.
On the "...get it credited back..." and other billing & payment concerns, these would be best addressed by Customer Service. Please go to http://ww2.justanswer.com/help
Good luck and thank you too for the opportunity to be able to exchange information.
