LCD television sets dos'nt have crt's, but ofcourses out of the RGB circuitry, R & B circuitry is'nt working or its not receiving the proper signals, that's the reason you see only green color,
If you are feeding the signal thru DMI/RGB cable from your set-top box, check for cable loose contact, cable wear-out, if you are feeding the signal thru coaxial cable its problem within the TV's circuitry.

For what it's worth, you can download the official
Sanyo repair manual for this TV (DP42746) at http://www.eserviceinfo.com/downloadsm/43343/sanyo_dp42746.html.
I uploaded it here when I had some issues with this TV last year.
The solution almost always seems to be to replace the Power
Board and the Upper and Lower Y Buffers. The parts and costs (from Sanyo in
July 2009) are listed below (NOTE: Sanyo will not ship these parts to anyone but
a repair shop):
1. V4 Y-Main (Y-Sustain) Circuit Board (Part # LJ92-01200A, Alt Part # LJ41-02759A) - USD $139.00
2. Upper Y-Buffer Circuit Board (Part # LJ92-01202A, Alt Part # LJ41-02760) - USD $64.00
3. Lower Y-Buffer Circuit Board (Part # LJ92-01203A, Alt Part # LJ41-02761A) - USD $64.00
Sanyo charges USD $10.50 for shipping, which brings the total cost for parts to USD $277.50. From my research, a shop would probably charge between USD $500 and $700 to do this repair. FYI - there is a class action lawsuit pending against Sanyo for this issue. The V4 Y-Main (Y-Sustain) Circuit Boards fail VERY frequently in this TV due to overheating. Hope this helps.

Try disconnecting the connector KBL on the main board as shown in my picture #DSCF0585 to see if the backlights will come on, if it does, the main board is bad.
Also check the voltages on the output connectors of the power supply.
