If you do not get any pictures with any kind of video sources, then there are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Sony Bravia flat screen TV when turned on has black screen. Green light on the bottom is lite up, electric plug is plugged into house socket, no picture only black screen.


If audio is OK, the fault is with its backlight section. If audio too is absent, the fault is with its digital main board. If you wish to get more details visit the site linked here. Pull up older posts.

hi,
You have to check the digital audio assignment of you AVR for HDMI 1 and HDMI 2. There is three options for the digital audio for HDMI 1 and HDMI 2. You can set it as optical ,coaxil, or the HDMI itself. In you receiver the assignment may be in optical input or in coaxial input for the two HDMI inputs.

1. Go to the system setup
2. Select input setup
3.Select input assignment.
4. Select all the three input ,you are using as HDMI

ok

Hdmi will not work only use of component cables will.


Hello

The HDMI[1] input on your TV receives digital audio

and uncompressed digital video and audio from an

HDMI device or uncompressed digital video from a

DVI[2] device.

This input is designed to accept HDCP[3] program

material in digital form from EIA/CEA-861/861B-

compliant[4] consumer electronic devices (such as a settop

box or DVD player with HDMI or DVI output).

The HDMI input is designed for best performance

with 1080i high-definition video signals, but will also
accept and display 480i, 480p, and 720p signals.

To connect an HDMI device, you will need:

• one HDMI cable (type A connector)

For proper operation, it is recommended that you use

a short HDMI cable. You should not encounter

difficulty if you use an HDMI cable shorter than 16.4

ft (5m).

HDMI cable transfers both video and audio.

Separate analog audio cables are not required (see

illustration below). Some CDVs (video CDs) may

not output digital audio signals. In that case, you

may hear sound by connecting analog audio cables.

However, if you connect analog audio cables with

this connection, the HDMI terminal on the TV will

not receive the HDMI digital audio signal and you
will hear analog audio only.

To ensure that the HDMI or DVI device is reset

properly, it is recommended that you follow

these procedures:

• When turning on your electronic components,

turn on the TV first, and then the HDMI or

DVI device.

• When turning off your electronic components,

turn off the HDMI or DVI device first, and
then the TV.

To connect a DVI device, you will need:

• one HDMI-to-DVI adapter cable

(HDMI type A connector)

For proper operation, the length of an HDMI-to-

DVI adapter cable should not exceed 9.8 ft (3m).

The recommended length is 6.6 ft (2m).
• one pair of standard analog audio cables
OK

Unfortunately only the higher end Onkyo Reciever pass audio over HDMI for sound. 605,705,805,905 exc. Your reciever will carry Video over HDMI but you will need a digital optical cable for sound.
