Toshiba Tv 50H71


This is like so many sets I have seen here. This problem has to do with the shutdown circuit turning the set off to protect it. As has been said many times this is a problem with the HV section which inclused the deflection, convergence, and horizontal output. These sections can not be repaired by someone who does not have electronics experience. I would suggest that you take this telvision to a repair shop in your area.
