If you have no indicator in the front at all, it means that the 5vdc standby power supply is not working, it needs this voltage for the TV to start up. Please read my guide to understand more.

Toshiba regza 42rv535u not working, has blinking yellow light, light blinks 3 times


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

Toshiba 42RV535U again. I detected 3.6V at AC DET and 2.9V at Power Sig pins on the power supply board, instead of the 2.9 AC Det and and 3.2 Power Sig specified in the 42RV535U service manual. Could this...


Are you blowing any fuses - if not, good. Hopefully nothing is shorted. Inspect the power board thoroughly for bad capacitors - look for bulging. Inspect the circuit traces for cold solder connections. Also, check the Zener diodes for a voltage drop - one of them may be bad. I don't think the inverter board is bad. I think you're on the right track - THINK!
