Turns off automatically after 5 seconds. Momentary display of saturated picture and sound from memory. Brief menu display, superimposed on screen. Could this have been caused by a spike on the cable...

Won't turn on


The clicking you here is the mosfet trying to turn on power on the the oscillator then power to the tranformer. The thing with red wire come from the top to a anode splitter. The question is where the power stops. You know it is going to the mosefets but is the trasformer powering the tubs. Email me for anymore questions Christopherclhurst@hotmail.com

Three seperate colors on Screen


Screen may have a hair line crack in it causing projection to be distorted. Inspect screen very closly with magnifying glass if necessary to insure no cracks. If crack is found replace screen.

1 Answer

Loud electrical sounds


It sounds like the Power transistor that drives the High Voltage Transformer shorted out. The rapid clicking sound you are hearing when pressing the power button now is that of the power supply starting to come up, detecting a short circuit and shutting back off again, preventing further damage. It is likely that the HV Transformer is shorted as well which usually causes the Output transistor to fail. Since the set is only 2 1/2 years old, it is probably worthwhile getting it to a repair shop as long as you have been very satisfied with the picture quality up to this point. If the picture size was larger than you needed, you might consider going down to a 37" LCD HDTV set. Toshiba is tops in this category IMHO.
