Question about Toshiba 43H70 43" Rear Projection Television
Hello all. I do build, repair and upgrade computers. Not like in the old days now. No more soldering cpu's and other componets anymore. : ) When I bought this tv, I already knew about the convergence problems some have. Been lucky for the last 5 going on 6 years with mine. I replaced my convergence IC's when last month, my tv would sometimes just shut down. It would come back on after it cooled off. Now it will only play sound with no picture. After about 2 minutes, there is a click sound and the sound goes off and the power led starts to blink slowly. Press the power on button again and the power led starts to blink rapidly. Figure maybe a fuse(s) went with the convergence IC's? I have no clue. Any help would be greatly appreciated. Have no manual for values for the works of this tv. Thanks Sam
Also check the horizontal o/p transistor for short if ok ,look on the deflection board and see if there are any b+ voltage markings and test with meter for b+.
