Hello
Check its CRT base connecting socket. If the Focus pin do not get proper connection, this type of fault can occur. Replace the CRT base coonector socket, which can be located on the base card, directly soldered on to. You can desolder it out from the baord, and can insert a neq one in place, and solder. This is not a very skilled job. If you are handy, and have desoldering and soldering equipments, you can do this work by yourself at home.
The suggested part, can be bought from most of the electronic spare part selling shops at your town. Hello Check its CRT base connecting socket.
