I have a Toshiba 51h84.I push the power button and I get a solid red power light. There is a click from inside, kind of like a relay clicking on. No picture, no sound. If I leave it on I get an occasional low thump type noise from the speakers.

Try checking the fuses in the back of the tv

Go into the service menu and turn down the red push and red cut a few notches. Write down every value in the service menu and be careful to make sure you don't change anything else. Also, turn down the brightness a couple of clicks and the red glow will be gone.

Or, try this - Press Mute on the remote control twice, press Mute a third time and keep holding at the same time, press the Menu button on the TV front panel. If you do it correctly, you will see a small S on the screen. Congrats, you are in service mode. Press Menu on the remote to get to the adjustable settings. Be careful not to change anything without writting the original value down first. Also be careful of hitting other buttons on the remote. To reduce red push, Use the channel up down button until it says RCUT. Adjust the value using the volume button on the remote. I recommend setting RCUT to 80H, which is the preset value according to the service manual. To exit Service Mode, simply power off the TV. Good luck.

tv will not power on. red light on switch blinks. power relay clicks, but no picture or sound.

most times then not it's the capacitors on your power board that blew there for not supplying the tv with enough power if you open it up and check the capacitors it should be leaking some kind of liquid or the tops have bubbled up. its an easy fix cost>>2 dollars each

must be some of parts broken down. you have to check powersupply thorougly.

send $9.99 & you too will have the answer.

convergence IC's need to be replaced

The click might originate from the cd mechanism, you might be expriencing some electrical display problem.
