It is probably your horitzontaltransistor that is shorted and it will have to be replace and it is located need the fly back transformer, on a metal heat sink, and to have it repair you are looking at around 400.

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.

Red power light continuously blinking. no picture no sound.


It could be the lamp went out and needs replacement. The Toshiba website states when this happens to unplug the televison for 10 minutes then plug back in. If that does not work then try another power outlet. If that does not work then call for service
