I have the same type of TV, and I think it has a filed "power rail", as the LED does not burn at all, nor do the heaters of any of the CRT's. When I plug it in, I can hear the relays click in, and hitting the power button will cause the relays to click. Other than this, there is no sign of life from this TV. I really would like to find a repair manual or a schematic to aid in troubleshooting. The self-diag trick may be handy if the LED would come on. I'll try it and see what it does.

Nothing. I have a test button, two input buttons (an up and down), and two adjust buttons (up and down). No menu button, and no remote (it may come with one, but I got mine second-hand). Schematics would really help me here.
Fixed it! Turns out that an RF-stopper inductor (basically a wire wound a couple times through a ferrite bead) has become partially unsoldered, and the connection heated up hot enough to fricassee the board (turning it dark). Simply resoldering the connection brought this TV back to life.
This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems, to activate this turn the unit on let it shutdown then press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source
