Replacment of the picture tube which probably will not be cost effective on
a 19" tele. "Cindybear" wrote in message ...

I'm thinking I'm screwed and will have to buy a new TV but I'm wondering if there is a cheap fix for this? I suppose I could take it to an auto glass shop and have them fill it, but that's more of a structural instead of a cosmetic repair, right? I've been watching the TV with the chip but it's getting more and more annoying. A good place for this question is sci.electronics.repair. I've crossposted it there... |
I suppose if it was filled with a material of the correct
refractive index (glass presumeable) it would be less noticable. However you are probably still going to get reflection at the join. I was thinking of how small scratches on CDs can be fixed (supposidly anyway) by filling with an apporpiate material. It can hardly make it any worse anyway. Another option might be 'resurfacing' but maybe to expensive and dangerous. "Cindybear" wrote in message ...

I'd suggest filling it in with the automotive stuff. The refractive index
of the stuff has to be much closer to that of glass (1.5) than to that of air (1.0). How *deep* is the chip? Is this the front of the picture tube itself or is there protective glass in front of it? A picture tube can burst rather violently when broken, because of the vacuum inside. |

It's not terribly deep and I think the chip is confined to the protective glass, but I'm not sure how you would be able to tell if it was the tube that was chipped. If the tube decided to self-destruct, would I have to worry about flying glass? |

If the tube decided to self-destruct, would I have to worry about flying glass? There may not be any protective glass - it's just a single piece. CRT implosion is a very violent event, but also a low probability one if it's only a small chip. You'll probably never totally eliminate the appearance of the chip. So, if it's in an very annoying location, probably a good excuse to get a new TV. --- sam | Sci.Electronics.Repair FAQ Mirror: http://repairfaq.ece.drexel.edu/ Repair | Main Table of Contents: http://repairfaq.ece.drexel.edu/REPAIR/ +Lasers | Sam's Laser FAQ: http://repairfaq.ece.drexel.edu/sam/lasersam.htm | Mirror Sites: http://repairfaq.ece.drexel.edu/REPAIR/F_mirror.html Note: These links are hopefully temporary until we can sort out the excessive traffic on Repairfaq.org.

Not to worry 'cause worry is wasteful and useless in times like these. Don't worry, be happy. Don't worry baby, everything will turn out all right. But you wouldn't want to be nearby if it happened. Sitting a few feet in front of it would be a particularly bad place to be. You might want to ask yourself questions like "Why did they make that picture tube that exact thickness?" and "How much safety margin does that particular CRT manufacturer believe is adequate?" and "Does a brittle substance really become much more prone to fracture when a small surface defect is present?" and "Do I really want to risk high velocity shards of glass flying at me when I'm watching Reno 911?" and "How much money are my eyes worth to me?". And you may ask yourself - Well...How did I get here? Same as it ever was. David |

And you may ask yourself - Well...How did I get here? This is not my beautiful house! Uh, anyway, I took a closer look at the chip over the weekend, and as far as I can tell the screwdriver put a very small (~1 mm diam.) hole in the outer piece of glass. It looks like there is a small (couple mm) gap and *then* the surface of the tube, which appears to be unscathed. I don't know if that makes sense, but that's what I saw. I'm thinking about getting the glass repair doo-hickey from the auto parts store. Meanwhile, I will continue wearing safety goggles while I watch Reno 911. |
