Samsung tv
schematic this time there are new. it is widely used on the mainboard
samsung tv output in 2005 and upwards. the usual obstacles faced by this tv is the standby position and can not be in on it. First we measure voltage 115v b + and showed a normal mean. ic voltage 5V and the program also exist. ic voltage 8V to OSI; ator is also no problem. incoming voltage to 12v input travo also exist. voltage on the pin just a horizontal base of the
transistor 1-2v should not go out at all. but the pin out of the normal output of the oscillator. after checking details of damage lies in the fact that protectionism is not working normally. then just remove the protectionism which diodes are in a series of vertical lines. and try to turn on tv and the results came out normal tv picture. see schematic tv samsung.
