Question about Toshiba 42HL67 42 in. LCD Television
First off....don't listen to ihatetvs, he wants you to check menu settings when your tv WON"T POWER ON.
When the power is removed from the set it is normal for the yellow LED to flash in sets of three when plugged back in. It will continue this until the tv enters "standby mode" at which time the yellow LED stops flashing, then you can power the tv on. If the yellow light (LED) continues to cycle through sets of three flashes and never comes on, you probably have some bad or borderline electrolytic capacitors on the power board, Best advice I can give the novice, if you can use soldering/de-soldering equipment, is replace ALL electrolytic capacitors on the power board. If you are NOT EXPERIENCED with replacing electronic components, STAY OUT of the tv and let an experienced tech do the work. Better safe than sorry.

Make sure the power save setting is not on it turns the tv on slower > see if picture settings such as contrast and brightness are all the way up > or picture profiles are on right setting .e.g cinema is usually dark screen

I followed the steps at the following link and it worked for me. I have a 2007 Toshiba Regza 42HL67, but the firmware applies to many models as documented in the readme file at the location found via the link below. I used a 1gb SD card formatted FAT16, copied the unzipped files and folder to the card (wasn't sure if it required the top level folder or only the files under the top level folder so I copied both to the root of the SD card), unplugged the TV, inserted the card, plugged in the TV, waited 2.5 minutes, unplugged the TV, removed the card, plugged in the TV, yellow light flashed 3 times and went out. I turned on the TV and it has worked normally since last night.
