Removing physical blemishes from CRT? - test-drb@ccmp.vtda.org

13 Apr 2004

Hi
 If it is a TV, the front is a protective glass and is not
under the tension of the vacuum. Most CRT's for scopes
expect there to be a plastic ridicule in front to protect,
so doesn't have any protective glass. The glass used on TV's
is ordinary plate glass and not tempered so it can handle
scratches without failing. Even a crack will not propagate
to the inside glass.

 Although the CRT in question is off-topic, the question is fairly topical:

 Is there any way to remove physical blemishes from the face of a CRT?
 I've got a very nice 19" SVGA display that has some scratches on the face.
 They are somewhat invisible unless you happen to be looking at something
 at that part of the screen (lower third, right of center).

 Can this be buffed out or ... ?

 I hope there's a way to do this because I've been wanting to fix the face
 of my 35" ProScan TV that has the same problem.  You barely notice it, but
 it is slightly distracting when you do. 
If the scratches are minor, so the CRT faceplate is not significantly 
weakend, then there are kits available for polishing car windscreenss 
(Oh, OK, auto windshields, right?). They'd probably help.

If the CRT faceplate is weakened, then replace that CRT before it implodes!
