Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

No you can not take the screen off to look inside. These sets are accessed from the rear, however do NOT attempt this on your own as there are fatally dangerous voltages present.
Visual anomalies on a projection TV are due to bacteria growth in the projection coolant.
Frankly it is cheaper to throw this away and replace with a modern flat screen that can be hung on your wall.
Here is one for $329

Well it sounds like a deflection circuit/tuner related issue. Is the sound affected when the picture jumps?

You need to replace convergence out chips in your Toshiba 57H81 tv by qualified tech because 3-D look picture in rear projection tv shows some thing wrong with convergence output chips.
Your tv model number shows it is rear projection tv that use 3 tubes to make color picture on front screen where as dlp tv use one lamp as back light source to present picture at front screen that is generated in light engine.

Hello,

Projector TV's have a tube for each function e.g. Video 1, Video 2, TV. Does the TV just not work or the VCR<DVD<Game console modes not work as well? If one works and the others do not you should be able to replace that tube, module, piece.

I hope this helps.
