                          SCC_71956: Intermittent flickering picture.


Needed components:
 996510032437: 560uF_20%_200V LS561M2DBK-3025A (from Lelon).
 319802134710: 470R_ 5%_0603.
 319801790040: 47nF_X7R_16V_0603.
 319802051390: 13V zener BZX384-C13 (if damaged by displacing it).

Step 1: Replace the mains elcap 2111 by: Lelon LS561M2DBK-3025A.
Caution: use only this type, as the height is important w.r.t. safety!.




Careful for the polarity of the capacitor and the wire 9047 under the elcap 2111.

                          SCC_71956: Intermittent flickering picture.


Step 2: Check for former rework instruction of adding 270k on position 3115.
Add 270k if not already done.


                                                                          Former
                                                                          rework




Step 3: Displace 6155 as depicted (do not change its polarity!!), to be able to add a 0603
resistor in series.


                                                                        Displace
                                                                        6155 (keep
                                                                        same
                                                                        polarity)

                          SCC_71956: Intermittent flickering picture.


Step 4 Add a 470 ohm resistor in series with 6155 as depicted.


                                                                      Add 470R in
                                                                      series with
                                                                      6155




Step 5 : Add on top of the 470 ohm (in parallel) a 47 nF capacitor.


                                                                      Add 47nF
                                                                      parallel to
                                                                      470R

                          SCC_71956: Intermittent flickering picture.


Step 6: Remove 2110 or 3116 (one is sufficient, as they are connected in series).


                                                                     Remove
                                                                     2110 or 3116




Step 7: Check carefully if al solder joints of the rework are OK .



Caution: Put the components on the place as depicted and do not
use other components than SMD (leaded components could come
in the 6 mm safety zone!).
