Samsung Tv 29" Led flashes on & off
Hi everyone,
i've got a Samsung Tv 29" Model CS 761BG using 3S 1265R in its power supply. Its problem is that the led is flashing on and off and no voltage is present in the secondary of the supply even on the collector of the output transistor.A component test was done and no faulty components was found but when it was re-assembled the tv worked again but after two weeks the same problem happened. What can i do?? *Note: Dry joints was done on the entire board..... |

I would be looking for a cold solder connection, or a component that is
mechanicaly intermittant. Usually failing components become thermo sensitive, or simply fail and stay failed. Jerry G. -- |
