Please read my guide first to find out if it is the backlights inverter, T-CON, or power supply or the main board.
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. If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on: Basic LCD monitor and TV troubleshooting guide: http://www.fixya.com/support/r5093881-lcd_flat_panel_tv_troubleshooting_guide http://www.fixya.com/support/r6150077-basic_lcd_monitors_troubleshooting http://www.fixya.com/support/r7406380-tv_training_manuals Failed TV and Monitors: http://s807.photobucket.com/albums/yy352/budm Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague Parts: www.shopjimmy.com Capacitors kit: http://lcdalternatives.auctivacommerce.com/Default.aspx he can make you a set of caps.

He was wrong... HDMI is just an audio/video format for high quality video and sound. That cable also contains the sound that goes with the picture. If it has sound but the picture is not there then the HDMI cable is probably OK. A simple way to trouble shoot that is to use a different input. For example Component Video. You will need a different cable for that. It only contains the picture (three wires), then change the input to component video. That's a menu setup. If that restores normal operation then your video is just fine and probably the HDMI cable is fine. The trouble may be in the connections behind the jack on your TV.
They are subject to mechanical stress when the plug is inserted and removed. They should be fine but if the connections weren't perfect from the factory they can cause microscopic cracks that will show as things like no video or intermittent video. You can bypass that connector by using a different audio/video input. If that fixes the problem then leave it that way. If it doesn't it's still likely to be a cracked soldered connection but elsewhere in the set.

No you can't. It has no such facility.

replace another similar screen

The first troubleshooting step would be to play around with the audio and audio output settings on the Comcast receiver. If you have it connected to your television with an hdmi cable the output should be changed to hdmi. If it is set on bitstream change it to pcm. If you have the choice of setting it on 48khz or 96khz then do so. It is in the Comcast receiver's settings if you are getting sound when connecting other devices to the television.

possible T-con problem but check LVDS cable first and don't forget checking capacitors from the power supply board
