I had the same problem and called Sony, they just said to keep trying what the manual says to do, but make sure the unit is in standby mode. I tried in powered mode and in standby mode many times and it did not work. Then I tried again the next day when the unit had been in standby mode for an extended time period. I hit the four buttons like the manual said, all four in quick succession. I also tried the four buttons in many different sequences from what the manual said. When I powered back up the lamp timer was set to zero, finally! I think having the unit in standby for an extended time was the key. The Sony rep really emphasized the need for the unit to be in standby.

I don't know the model but it would seem a reset would do the trick. See if there is a button on the cpu board and that should do the trick if not try unplugging a re plugging unit . Logic needs reset by a switch or by removing power
Sir the problem of your unit is the lamp try to replace it it is much better to use a gloves and wash your hand after replacing the lamp because this lamp contains mercury. follow this steps.
1. Unplug the unit to main ac outlet. Remove the bulb housing cover from the back of the TV. Using a screwdriver, carefully remove the cover to reveal the old bulb. Using a cloth, remove the bulb from the TV by first unplugging it from the wiring harness. Carefully rock the harness back and forth until it comes free from the bulb. Push in the bulb slightly and turn it a quarter-turn to remove it from the bulb housing. 2. Install the new bulb. Do not touch the new bulb with your fingers, as any grease or fingerprint from your hands will damage the tiny mirrors in the bulb. Instead, carefully handle the bulb using the cloth. Insert it into the bulb housing and secure the door. Test the unit. Plug in and turn on your Toshiba TV and make sure that the new bulb is installed properly and that the image looks crisp.
3. Reset the lamp time counter. Each Toshiba TV comes with a lamp hour meter stored in its software. If you do not reset the lamp timer, the unit may stop operating when it gets to a certain time (refer to your manual because each Toshiba TV is slightly different). To reset your Toshiba lamp timer, turn off the TV, wait 10 seconds, hold down the "on," "menu" and "input" buttons on the remote at the same time, and turn the power back on. A yellow light should appear in the bottom corner of the TV indicating that the lamp timer has been reset. Hope this help good day and best regards.

I think it's a lamp driver issue from what I've seen others have gone through. I also read that if you go through the sequence of unplugging, plug back in, wait 20 seconds and try to turn on, multiple times, it will finally kick on and work. I just got mine to turn back on by doing this and waiting through the fan cycling without the light turning on. After the 4th sequence the light flickered. After the 7th sequence it finally turned on and is working. Now I can watch the Super Bowl and will look into replacing soon.
Honestly I would try entering the 'Lamp timer reset' code again. Or the button sequence given to reset the lamp timer. An issue that may be happening is that something may have happened to the lamp ballast power supply also. Just a thought. Blessings always,

In order to reset the bulb counter you need to access the Service Menu: To access the Service Menu: Turn on and warm up press the following sequence: Up Up Left Give it a few goes, it took me 5 minutes to enter with the right timing. The Service Menu will appear, highlight factory reset and the counter goes to 0. Job done. Cheers, Matt.
