I had a similar problem to this yesterday. Tv is same Toshiba model as you mentioned about 4 months old. In my case, after the TV working perfectly following installation, the standby LED on the front (the one that is red on standby and green when on) went to a flashing orange (after switching on from standby) and the picture disappeared although the sound remained OK. I was unable to get any response from the setup or menu on the remote, otherwise I would have tried resetting the TV. Regardless of how much switching off/on (including disconnecting the powerlead and leaving for few minutes), disconnecting all peripherals, etc., nothing helped. I looked up Toshiba's web site and under support they basically suggest switching off the TV and restarting using the onset buttons (not the remote) and pressing the menu button (again the one on the set (not the remote) and if you could get the menu box to appear then reset to default settings. I tried this but the results were the same. I therefore thought the TV was defective. However, after much frustration I did the following (I think): 1) Disconnect everything from the TV 2) Powered up from the mains switch whilst keeping BOTH the startup and menu buttons on the side of the TV pressed down. The result in my case was that the standby led and one of the two beside it flashed green simultaneously. However, when the buttons were released, the TV started up the same (flashing LED orange and sound no picture). 3) Pretty well defeated at this point, after doing the procedure at (2) several times with the same results, I somehow thought of pressing the standby button on the remote either whilst the two buttons on the set were depressed or just after they were released. I am afraid I cannot remember which and cannot replicate the problem as I don't know what caused it in the first place. 4) The TV then started normally ( no reception as I had not aerial connected, etc.,) but I was able to gain access to the screen menu/setup buttons via the remote which were in French rather than English. However, after reconnecting everyrthing the TV has worked fine (obviously after resetting the language via the menu). I am sorry I cannot be more precise but I hope this might be of help to someone with a similar problem.

I had exactly the same problem When the TV was switched on all I could
see was a flashing green light. After cheching the TV internals and not
seeing a problem including the power supply unit which looked and
checked normal. Here is what I did to get M TV working again.
Disconnect it from the power supply. Hold down all the buttons
simultaneously i.e. the on/off, the volume, the programme, menu
buttons, all of them simultaneously and Plug it into the power supply
Lo and behold My TV jumped back into life after an absence of about 4 weeks.
Try it yourself exactly as above.
