It is rare in this set but it indicates a short somewhere that is pulling voltage inside the set down---not a do it yourself repair unless you are a Technician with some basic equipment and a schematic diagram.
If the red light won't come on it is not getting power.First,try plugging it in to a different outlet,or unplug one of the gadgets you know is working and plug the tv in there.You are simply switching.If you know that there is power coming from the outlet and it still won't come on then you'll have to check the cord;don't go much farther than that without expert help.
There could be many items that can cause that symptom. However I always assume convergence on any rear projection which can easily be checked by unplugging the convergence amp board and then plugging in the set and press power , if the set powers up turn it back off, and you will know the convergence ICs and associated resistors on that board have failed. Although its easier to replace the board unless you have good soldering skills. I am pasting a pic of the board which is suspended above the main chassis just mark the wires then unplug the set from the wall first, but then unplug the wires from that board and then try powering up the set.if you need further assistance , respond to this same post
hi, you might get lucky and have a locked up micro, un-plug the ac cord for 1 minute and then plug back in, this will do a hard, set-re-set of your tv. If still dead then power supply has been damaged and you`ll need a tv tech to diagnose it, good luck, video-tek
If you hear the unit comming on and theres no sound or Picture, then theres a fault in the horizontal sweep/HI Voltage circuit. This should not be fooled with unless you know the safty issues with HI voltage as theres voltage in these sets even after they are unplgged for a while. Good Luck
