If it's failing to stay on, the main power supply is probably at fault and without some technical background and a couple of test instruments, you will not be able to do the repair yourself. 
What you can do though is; unplug the set, let it stand overnight or at least several hours, remove the back panel and look for a separate board with mostly larger components on it; it will have a ferrite core (no laminations as with a line-frequency part) transformer on it and several larger capacitors which are cylindrical and mounted vertically to the board.
 
Before touching anything inside, especially on that board, allow several hours to be safe since the larger capacitors can hold a painful voltage charge for some hours.  
 
If you see signs of overheating such as discoloration of the board material, it may not be repairable but if you can find a part number on the board, you might be able to buy the power supply and install it yourself but it will likely develop the same problem eventually unless they have altered the design.
If there are no signs of heat damage to the board, there may be companies offering to repair it as a subassembly instead of repairing the whole set which could be much more expensive.
If you choose to replace or have it done, the power supply still may not be at fault since most are capable of switching on and off if a downstream problem is causing an overload.

If you have sound and no picture, it's time for a new lamp.

Power indicator blinks; but no picture.


Likely to be the STK convergence chips causing a protection circuit to cut in and switch the TV off when turned on. Do you hear clicking when you switch on?

Toshiba TZ43V61 43 in. Rear Projection... Problem


Try unplugging unit for 5 minutes, then plug in and turn on. If this works, your power supply may be going. However it is more likely that the bulb is gone, you can replace it yourself, but make sure you get the right bulb for that unit and take care in the installation of it.Go to the manufacturers website and look up your model and find out how to inspect and remove the bulb.
Bulbs can run for 140 to $300 and can be found on EBAY

My Toshiba now plays B & W


Maybe the color killer in the remote control is activated. Try disabling it. Now if nothing happens even if you adjust the color using the remote, the color demodulator maybe is at fault. The three primary colors is derived from this IC component and then amplified through the transistor color amplifiers, one for the red, green and blue. Try checking also the video driver transistor in which the three color amplifiers are connected. This might also a good suspect.

Toshiab tz43v61 power light blinking


I had the same thing happen to me 3 times and the first time it was 2 months off of warranty. It is costing me $395.00 each time, the TV is only 7 years old. Lets see I paid $2400.00 for the TV and also have another $1185.00 into it for repairs, and it is doing the same thing again. My suggestion would be NEVER buy another Toshiba product. I find it interesting that their website says "As a proven technology leader, Toshiba is committed to the goal of ensuring that, to every customer, the Toshiba name remains synonymous with lasting quality, durability, and value." WHAT A LOAD OF ****!!!
