Contact the authorized service center for Toshiba.

Please send me an email to [email protected] Put "toshiba 57h83 manual" as the subject and I will send you the manual right away. Lawrence Brown

Check vancebaldwin.com or shopjimmy.com

go to google input the model and find a free manual.

I would suggest to leave your directtv hd/dvr box connected the way It is.
The HD Colorstream 1input on your TV should work just fine.
This TV does not have an HDMI input but you can buy an adapter and connect to DVI/HDCP IN and that might be able to get 1080i video resolution on your TV.

Most often No Sound with Toshiba 57H83 is:

1. TV has a Sound on-off switch on the input panel at the rear of the TV. Very hard to see, black on black. Used to turn off speakers if you use a separate or external sound system for speakers. Usually gets moved while connecting hd cables or dusting and vacuuming in cramped space at the rear of the TV.

2. Someone accidentally changed Sound settings with remote to CC (closed caption) or SAP. Turn off in sound menu and save preference.

3. Sound input plugs from external cable or sat box unhooked or wrong input.

Toshiba 57H83 no sound fault is not common. If you still have no sound, get local service.

Or troubleshoot yourself to determine if Tuner, IF, processing, sound demod, switching or sound output circuit is smoked. Then make an installation plan.
