Do you have sound?
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.

Hi, The set top box will more than likely have two coaxial connectors ( threaded/ribbed pieces of metal ) coming out of the back. also three R.C.A. connectors-these will be smooth and be colored yellow red and white. one of the coax connectors will say " IN FROM ANT> or CABLE IN) the other ( OUT TO T.V. ) hook up your dvd recorders " ANTENNA " input to the set top box's ANTENNA output. If your D.V.D. recorder doesn't have an antenna input then hook up the recorders audio/video input to the set top box's audio/video output. then you should be good to go. If you buy a H.D.T.V. tuner to receive FREE H.D. programming it may be possible to hook up to recorder with H.D.M.I. cables.( those connections resemble slots ) I hope this has been of some assistance, good luck, Prodzilla.
