Hitachi 65F710 tv goes blank for a second...

Change battery

Sounds Like the graphics chip is starting to go. Try CPR in NYC. They usually have a 1-3 day turnaround time, and are pretty cost effective. You can easily ship them your unit. They are faster and cheaper than Sony.

Check the TV's video settings against the game consoles and see if they match.

You need a new blu-ray laser. model number kes 400aaa. takes about 30mins to change out.

wow its weird the ps3 dvd drive is not messed up my the laser that reads data every mili second is actiong up skipping over movies with a lot of dialoge

power in the tv has nothing related with the DVD. The tv has to have raster (white screen) even without signal (cable, DVD, others) if the tv alone is just having the led flashing and neither sound nor video (black screen) The tv has a short circuit in some of the boards that are part of the tv system. the blinking is part of a protection when the tv was created in the factory. Refer to the technician to repair this problem.

Does it do this with all Blu-Ray movies?
Have you tried a different HDMI cable?

My phillips tv model # 55pl9773/17 sound is too low when im watching regular tv, but when i switch from tv to av1 or av2 (watching a dvd movie or playing video games) the sound is normal. How do i get my cable TV to sound the same?

put in a disney movie or some rated g flick you should be able to re-set password

That problem might be on the remote of display settings on video display. There is one button that will turn that off. Try Display Settings
