Importance of a clean chassis

[ctc17]

I have found cleaning them causes mor problems than not. At this point I refuse to even blow them out. I can see where metallic dust may cause issues but not household dust.

I have a feeling you deal may be a fluke, sounds more like a cracked solder or intermittent issue in the CRT. I hope I'm wrong and your onto something.

I'm a bit surprised by this. I can certainly say I've never had a set that performed worse after cleaning out the dust.

I've had TV's or radios that simply would NOT play, and all it took to make them play was to get the dust out of there.

When I got into this hobby 20 years ago, cleaning out the dust was the first lesson I got, and was surprised at the before vs. after performace of the chassis being worked on.

I think Einar72 is right... I simply had a bunch of crap hiding under some caps and resistors. I just didn't get it all out during the first time I cleaned it.
