Facing TV Problems? Ask a TV Technician.
Hi and welcome back to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help on theis Second Opinion question.
Initially, bear with us; re-confirm and post back with the complete model number of the "...65 inch plasma Hitachi ultravision..."
I understand and when able please to enable us to determine troubleshooting/diagnostic flow/procedures.
Still, is the screen at least "priming"; i.e. black to dark gray when attempting to switch on ?
The only easy user doable try (for the moment and if have not been done) would be to unplug for an extended period of time. This is to simulate a soft RESET. Then plug back in but into a different outlet for test purposes.
Please post back results / observations of the above once tried.
All others would be internal as it most likely would be a hardware issue.
Yes please and post back the complete model number when able.
