| Repairing a video monitor in an IBM 3279 terminal |

Are you one and the same jmaynard associated with Hercules? If so consider this the Internet equivalent of being recognised in the street. ;) |

Electrolytics for $11 a piece- what do they look like? |
| jmaynard:
I am! And my goal here is to use the terminal to talk to Hercules with. |
| jmaynard:
I'm replacing 7 caps, so it's more reasonable than that. The most expensive is a 330 uF/200V, two of them at $3.70 or so. That $22 includes shipping. I'm in Minnesota, so getting stuff from Digikey is fast and cheap. |
| jmaynard:
It runs! Got the caps in and installed, and gave it a try... Now, need to figure out why the screen - the green in particular - is so dim. That picture was taken with the room lights off. The text that looks pink is supposed to be white. That's also with the G1 bias turned all the way down and the brightness turned all the way up. Are there drive adjustments or something on the monitor somewhere? Edit: Is this something that says I need a CRT rejuvenator? How do those things work with different picture tubes, anyway? Or was there one standard basing for them? |
