Thank you in advance! Did you honestly think that replying to an 18 year old posting was likely to get you anything more than insults? Idiot. |

It's been over 17 years since the original message was posted, so it's unlikely that anyone remembers the result even if it did get fixed. What have you tried so far to fix or narrow down the problem, if anything? It sounds like some kind of ghosting or ringing; is there a picture you could upload anywhere (Imgur or similar) so we can see what it looks like? I'd start by swapping the video cable and also trying a different video source, just to make sure it really is the monitor at fault. Then I'd replace all electrolytic capacitors on general principle. These monitors are decades old and there are probably multiple caps that have gone out of spec by now, so just doing the whole lot can save multiple rounds of troubleshooting. There's a service manual for this monitor available at http://www.zimmers.net/anonftp/pub/cbm/schematics/monitors/. The scan quality is poor, but it's certainly better than nothing.

The Commode/Amiga retro-scene is very much alive. Now I have posted lots of pics and info in this thread. I have already recapped the monitor and done a lot of measurements. https://www.edaboard.com/threads/commodore-1084s-monitor-with-faint-vertical-lines.396322/ I thought I'd also ask here as Alex faced the exact same problem. Thanks for your time Rayner. |

Small wonder, as hardly anyone uses a CRT these days... Normally when a CRT TV needs some form of repair, it will join its fellows in the recycling bin. |

You think?
