Hello Techs
This set came in yesterday with sound but no picture. Found HVOT 
shorted(D1556)(Q901) but before i install
the new one (2SD1556) i check the surrounding parts that connect to the 
transistor, D910, R961 and L903
and they check good. I also resolder the T901 just to make sure i have no 
problem. Now the set have High
Voltage and the picture tubes filament are lighted but still have no picture. I 
also check the voltage on
the CRT ckt and is 225V on all three CRT resistors. Now i don`t have an high 
voltage probe so i  don`t
know if the high voltage is reaching the picture tube anode. Does someone have 
any idea or tips that can
help me with. I`m free to any suggestion.

Thanks

Jose
