Question about Toshiba 56HM66 56" Projection HDTV
My tv only shows yellow light blinking 3 times ,over and over and tv wont star ,check lamp looks ok im running out of options model 56hm66 toshiba
Just called Toshiba about this. After the TV attempted to boot up several times.. the blue light, power light, came on. But the yellow light, lamp light, gave it 8 tries (just like the manual says it will) then the blue light goes out, and the yellow light (lamp light) comes back on with a red blinking light (red light is the fan light)
So mine was the fan gone bad! :(
So if you have a red light it's the fan, if it is the yellow light, its the lamp, and sometimes it may be both. If not, its the data board, which you can replace and reload too. So it's all fixable.
Try unplugging the TV wait about 2 hours. Then plug it up and turn it on. If it still does not boot up its one of the parts listed above. Thanks

Replace the lamp.

There is an unusually common issue with these TVs after nearly 3 years of use. Like florescent lamps, the lamp ballast eventually starts to slowly fail. This is one of the first indicators of it being near death. The TV will occasionally come on normally and stay on, and then, either not turn on, or turn off after a period of time. For the period of time that it auto-shuts off, check the fan first. If the fan runs fine, then the issue most likely points to the ballast. Toshiba is aware of this issue. Go to the Toshiba website and enter your TV's serial number. You may have one of the serial numbers covered under the lifetime replacement warranty that Toshiba has put these TVs under due to multiple issues with the light engine including the lamp ballast. If you're confident with just replacing the ballast board or pulling out the light engine (really easy by the way), you can advise Toshiba and just have them send the updated part designed to last longer.
