We have a older CRT TV screen that has a few small chips (5 in total)
in it, courtesy of our 2-year old hammering on it with a small toy
Most of the chips are the size of a pin-head, but one is big enough to
make it really annoying to watch hockey (it looks like the puck!)...
any advice on what can be done? Clear nail polish?
The general consensus in the electronics repair group I subscribe to and
where this question is frequently asked is that attempts at repairing
scratches or chips or other defects doesn't improve viewing and in some
cases can cause additional visual distortions.
yes, my thoughts as well, a CRT can implode with extreme prejudice.
Although if that happens, the 2 year old will likely learn not to
hammer on TV screens...
(seriously, don't let the 2 year old hammer on the TV screen, no
matter what you end up doing with it. Not only is it bad for the TV,
it's potentially really bad for the 2 year old.)
They only way I would know to fix it is with windshield repair resin.
(used for stone chips) You should be able to be a cheapie kit at an
auto parts store and do it yourself. All you need is the resin and the
plastic film to cover it out in the sun until it cures. (about 5
minutes) Then using a single edge razorblade scrape down the dried
resin until it's flat/flush with the screen.
Han a nearly new SONY about 20 years ago with a chip about 1/8 inch long and
1/32 wide. Deep enough to feel, Buffed it out with toothpaste - TV ;lasted
20+ years. The glass on the front of a CRT is nearly 3/4 inch thick.
I'd try the windshield repair kit from the auto parts store. Has some liquid
that soaks in, and dries clear.
Tip the TV so the screen is up, and clean the surface well (glass cleaner,
paper towels, and let it dry). Drip the stuff on, let it dry over night.
I've not actually done this, but it seems like it might work.
