Toshiba 56HM66. Picture freezes, then picture goes out. The blue light stays on and the yellow light blinks 15 times, 15 times, 15 times and then the picture comes back. The voice never goes out. This happens after the set is on for about 1 hour.

Toshiba 56hm66, lamp replaced but lights still blink


Check the circuit boards to see if any have failed. They are small cylindrical objects. If the tops of any of these are bulged instead of flat then they are bad and board will have to be replaced. Hope this helps.

I have a toshiba 50hm67 tv and with mine the blue light would come on and I would hear sound first and then the picture would finally come on... this happend for about a month.... next the yellow and blue light would come on but the pic still wouldn't come on until it clicked off and on by itself for about 10 min this went on for about a week. All of a sudden last night the red lights by the power light started blinking. No tv now and when the tv shut off it said lamp not working.

Picture loss after picture begins to flash. blue and yellow light


Most likely the lamp is dying. Try replacing the lamp before calling a repair tech. What does the Owners manual say about the blink lights?

Toshiba 52Hm85 shuts down after 40 minutes & goes on and off


Only a few things could make the picture freeze and shut down. I would recommend checking the DVI cable that goes between the Chassis and Optical Block to make sure it is secure and tight. If it is (and it probably is), most likely it is the Optical Block causing the problem.Because of the cost involved, I would have a Professional to come out and diagnose it to be sure.
I hope this helps,
