Hi guys,

I had a '93 20" Trinitron shipped to me that didn't have a safe journey.

However, the tube survived. After repairing the cabinet, I have a few questions about things I'm not sure about.

The speakers are torn. They are available as a 'special order' on partstore, but are expensive. What can I do about them? Here is a picture:

I set picture to 50%, with everything else at reset (50%) values as well. With these settings, the picture is good, but the black level is high and strong reds are more pink. Can I know whether the tube is at fault? There is little blooming and the blanking circuit un-blanks in 7 seconds.

The tube also has a small scratch on the front:

Is it possible to get it out? It is light, but reflects colors, and is annoying.

Thanks all. I hope you had a nice holiday season.

If it's just the foam, you might be able to get a re-foam kit from Simply Speakers. I've bought several kits from them and it is not that hard to replace the foam. Just something close to the speaker size should work.

Something like this (http://www.speakerworks.com/3_1_4_inch_speaker_repair_kit_p/swk325.htm)?

Also, is the scratch on the CRT face there to stay?

If yours is a 2 1/2" cone, it should work, afterall, we're not talking "Hi Fidelity".
I doubt if you can buff out the scratch, it usually distorts the picture somewhat. For real small ones, I've used "Super Glue" to fill in the scratch, then leveled it off, after drying, with a razor blade.
