| Now I have another problem with the same monitor:
https://www.youtube.com/watch?v=15PMwB8SENA (that's my finger at 0:23 on the right) The line is either at that position or close to the bottom, but can also appear anywhere in between. Is the fix as simple as replacing a cap? hitting the monitor with my hand does not help  |

| I usually go with no more than double the original. | |

| Ha, it works! It's alive!
It was 100uF 50V, which I didn't have so I've placed 100uF 350V, a really big one 
Thank you all once again! |

| That's great! Thanks to both of you. | |

| Yes, it is that IC. If you look at the schematics at page 3 and 4 in the data sheet, you see the capacitor connected between pin 3 and 6. | |

I've found IC401, but it is TDA9309 not LA7841L. Is that the one? If so, is it between pins 3 and 5, or 3 and 6? If it is, I'll have to unscrew every screw there is |

| Possibly IC401(LA7841L) ? | |

| No, none of these. I think it should be placed on the main PCB, not at the CRT socket. The casing is probably similar to that of the LM2402. | |

| The DIP40 is actually DIP56 ST72771N9B which is a MCU.
There is also this one M35071 There is one more IC that I can't get to, yet. |
