TV zapping, buzzing sound, help!?

Question

My son was foolishly playing with his BB gun and hit the TV screen with the BB. The TV worked fine for about 18 hours after this and now makes this buzzing, cracking sound and turns on and off. Can you tell me is this related or could it be seperate. The glass has a chip out of the front and almost like a fish eye behind the chip. Please tell me if this is fixable or not worth it.

Answer 1

Sorry but chip in the glass has penetrated enough to let the air into the tube. The noises are caused by the EHT voltage arcing inside the tube !

No repair is possible to the tube. Replace or scrap .

Cheers Pete
