ERROR MODIFY TO AMPLIFIER HIC1015, HIC1016 ( REPAIR )

DAMAGE OCCURRED FREQUENTLY

Based on the authors experience, the damage often experienced by these types of hybrid IC is damage to the error amplifier. As a result the voltage B + SMPS output voltage will rise to over work. Because the IC is also equipped with over voltage protection, then the TV will be ON while standby will then come back protectionism.
ERROR MODIFY TO AMPLIFIER HIC1015, HIC1016 

The main ingredient is the component modifications Sanken error amplifier Error (SE). If the error HIC1015 ampnya work on the B + 115 SE115 SE is used, whereas for the SE125 HIC1016 used.
While the modification steps are as follows:


A. Make sure that the hybrid IC can still be controlled ON / OFF by ic program. It can be characterized by the TV can turn a few seconds and then back to standby again. If found physical damage (burns / holes), you should not continue the process of modification, replace with new. In simple terms, make sure that the 'only' block error amplifier are damaged.
2. Remove the hybrid IC of PCB, then bend / cut pin3 of the IC is then put back to pin3 is left attached / no foot in the former IC pin3.
3. Pairs of Sanken error (SE) SE PIN1 way connected with the output SMPS B + (positive leg Elko B + output), PIN2 SE is connected to the former track and pin3 pin3 HIC1015 SE is connected to GND (negative leg Elko B + output). For more details, see figure 1.
4. Replace the resistor with a value of 4k7 in parallel to the foot of the anode and cathode optocoupler. The actual allocation for this resistor is there but the original is emptied (R881), see figure 2.
5. Ready to try on and measure the output voltage.
