try toggling the user brightness controls, if this didn't work, the inverter board is most probably the culprit, this is the part that supply high voltage to the light that illuminates the backdrop of LCD screens, consult a qualified tech to repair or replace this particular part. ;-)

The tv is capable of displaying 720p and 1080i HD pictures. But that box was designed to accept for use only HDCP capable connectors - the DVI from your tv isn't one so the image is automatically downgraded to SD wide.
To get an HD image you will have to use the analogue RCA Component connectors plus the audio ones.

First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board. if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.

All you need is an hdmi-dvi adapter. You will also need a component audio lead to plug into the mini(3.5) jack socket on the tv as dvi does not carry sound. You will need to initially use the scart to set up your tv for hdmi as the menu can only be seen via the scart until you set it up.

Use the SCART, it has Component Video connections that are capable of carrying HD signal at high quality.
