It's either signal board or light engine and unless you're really pretty good at electronics neither one is something you should tackle. I do have the service manual for this unit and I would be glad to send it.. Just drop me an email email@example.com and make sure you include the model number as well as what it is you need.. I get almost 650 emails a day so it's really hard to remember who's email goes with what problem. :) Good Luck Bill

You have bad capacitors in the power supply that took out the regulator, or the ballast circuit is defective. Not really a repair for the novice. Good Luck

They exact way the lights blink are telling you what the failure is. If the tv is firing the lamp and the lamp is bad, you will hear a buzz sound for about 1 second. The tv tries 8 times before it gives up and spits out the lamp error. Check the user manual for led diagnostics. If you put in a new lamp but still have issues, you've likely got a bad ballast (most common on this model) or colorwheel (less common). Both are part of the optical block (light engine) and I don't believe they're available as individual components from toshiba.

Ensure that you don't handle the bulb with bare fingers. wipe the bulb with meths and hold the buld with a lint free cloth when you're putting it in. If it's still blowing it's probably over heating so check the fan
