    An unusual problem. My 2yr old son Greg got hold of real darts and has thrown them at our panasonic 28inch CRT flatscreen telly while his favorite program bullseye was on Sky.[You couldent make this up].
    The result is there are about 30 pits and one or two 2mm across/0.5mm deep smallchips in the glass ,they appear as black dots etc from a distance .The screen isnt cracked so i dont think theres a safety issue but its annoying especially since i know they are there. Has anyone ever repaired similar damage? Im thinking of the car windscreen or scratch repair kits etc.Any advice would be helpful.

    I should add the 28inch is our second room TV and thank goodness the Main Panny 42inch Plasma has not been similarly damaged (panic !!. )Never the less I am gutted as the CRT was only just over 2 years old and I anticipated years of sterling service. Its not worth an insurance claim but if the damage can be cosmetically covered its something.

    I can't realistically see this being repairable. The front face of the tube is supposed to be quite tolerant to abuse, but i'd still be a little concerned about the fact it has been chipped, and this could fracture at some point considering the huge external air pressure involved, especially on larger CRTs.

    I went to the skip the other day to dump an old CRT. They have a special porter cabin there for old tv's. It was a Wednesday, so you wouldn't expect it to be busy... however there was a portacabin literally full of CRT's, and not crap ones either, I spotted a 32" Philips from the designer range, a 36" panny... some serious Tv's.

    So the point? Go down to your local skip, identify said CRT dumping area and bag yourself a new tv free.

    Many moons ago their were companines who would polish out minor flaws in CRT screens, it needed special equipment to do. To my knowledge they are all long gone. I doubt if the structural integrity will be compromised. The implosion protection on a CRT is pretty good. From my own experience suggest you see if the house insurance covers accidental damage if you cannot live with it. Alternatively its a spare set...

    Suggest you remove pointy darts from offspring and replace with the suction cup variety :)

    The idea of picking up a TV from the tip? Why has it been dumped??? Probably not viable to repair would be the obvious answer..

    Because you literally can't give CRT tvs away. Everyone already has one, and if people are getting a new one they get a LCD/Plasma. I've known at least 5 people now who have had to skip CRT's because they literally cannot give them away.

    Last year I got offered a Beovision free! Unfortunately I couln't pick it up so it went in the skip :O

    This can be repaired by a glazier, but it is an expensive process, and a specialist one at that as the equipment isvery expensive. IT also take's such a skilled tradesman to reshape glass, as it is such a precise art.

    So it would cost you more than a new Tv is what I am trying to say, quite why even a kid, would throw dart's at a tv screen is beyond me. My dad would have belted me up and down the place had I done anything like that and rightly so.:lesson:

    My daughter and her partner picked up a 3 year old 32" Sony Trinitron from one of his workmates who was throwing it out if they didn't want it :eek: If you are patient enough you could fill the pitted screen with clear superglue and rub it back down with fine emery then metal polish to finish it off similar to the method used to repair chipped windscreens I would imagine. It must be worth a try if it annoys you enough.

    Hm, I used freecycle to shift an old 4:3, working fine but not a great TV, and had about a half dozen people wanting it. In this part of the country, at least, giving the things away is easy (though they sell secondhand for pretty little...)

    I was told that chips and scratches cannot successfully be repaired on flat tubes, either by repolishing or filling.:(

    The reason given was that all flat CRTs have a coating on them which resists scratching and controls reflection. Any abrasive polishing removes patches of the coating and apparently this is more obvious than the original scratch or chip. The surface also has to be polished after use of any of the resin glass fillers.

    Unfortunately, I know from experience that the coating is not hard enough to resist the efforts of a 2 yr old... by strange coincidence my 12 month old HD CRT also sports a nice deep scratch, courtesy of our 3 year old son...:mad:

    It depends on the tube..Philips used to laminate on a plastic film, others used a wet coating process - the coating also darkens the screen (it's tinted.) Whatever, if you have damaged it then it's not readily repairable.

    I suggest you wait with the old 'un until your kids grow out of vandalism...

    Too right! He let a two year old play unsupervised with pointed darts? Still he should think himself lucky he isn't having to plan a trip to the eye hospital to get the nipper or its sibling fitted with a glass eye as happened to a mate of mine when a neighbours four year old got hold of some darts.

    I'm not absolutely sure he was letting him play with the darts, exactly... ;)
