DIY TV repair advice

Hi guys,

I have a 32" Sanyo tv which I use a a second set for my playstation 2.

Unfortunately my 3 year old thought it would be a good idea to attack the screen with a cordless power drill! (Minus a drill bit)

It now has small chip in the screen which is affecting my sniper aim.

I wonder if there is a product on the market to fill in the chip in much the same way that car windscreens can be done.

If so where could I purchase such a product or get a repair man to do the job.


Hopefully there are some tv repair men out there that can answer my question.

Thanks in advance

Hi, not what you want to hear I'm afraid but if the glass screen is chipped then the strength of the crt has been impaired. You cannot repair it and since the safety of the set has been compromised you must scrap it. Others will say 'Nah, carry on mate and don't worry about it' - but you mustn't, you must scrap it or get a new crt fitted. Perhaps you can claim on your household insurance ? So sorry, regards yt.

Agree completely.

Believe me, you wouldn't even want to be in the same room if the tube implodes, let alone sitting in front of it!

Now, if your 3 year old wants to be four...

I think you could be being a little over-cautious here. My experiences with CRTs as an engineer many years ago is that they are remarkably strong, even if chipped. The face of the screen is made of lead-crystal glass to absorb radiation, but is notoriously easy to chip or scratch. It is also probably around half an inch thick, hence much weight at the front of the TV. It is also incredibly strong. I have not known the face of any tube break, unless it was hit with some force with something weighing much more than a cordless power drill, thrown by someone much older than three years old! The weakest part of the tube is the end of the tube-neck, and even that needs a hefty clout to break it. (I know, I've done it several times using a heavy hammer to release the vacuum to make the tube safe if disposing of it)
Also, that same firm that employed me used a specialist glass "repairer" that ground down the glass to get rid of chips, and the tell-tale sign was a "flat-spot" on the glass. Mind you, that would not happen now though!

Hi, cant agree I'm afraid (and I too am an engineer with many years experience). The safety of the crt is compromised and must be scrapped. When ever I work on a telly/monitor that has a chip on the front of the crt I replace it without hesitation. To do otherewise would I suspect be a breach of current H&S regulations. I agree it is difficult to break the faceplate of a crt but nonetheless I wouldn't want 'fireboy' to be the first. We will have to agree to disagree - no harm or 'loss of face' in that. Regards, yt.

Thanks for the advice chaps

Seems a shame to scrap the TV for only a minor chip

I only asked the question because an ex Radio rentals engineer said to my father in law that he used to repair the scratches in rental sets.

It does indeed.

But if that "minor chip" has compromised the safety of the tube, then you have a potential bomb on your hands.

Still, it's your decision of course.

Good luck.

Minor scratches can be buffed out using a fine powder supplied by some CRT manufacturers specifically for the purpose. A very good substitute is jewellers rouge, used for polishing jewellery. This is only for minor scratches. Since you describe your damage as a chip, I would agree with the opinions above, particularly if the chip is deep with sharp edges. It's not worth the risk, especially with children around.
