  1. hello
    problem =
    5 year old 32 inch crt t.v makes a high pitched buzzing noise, this happens randomly, it goes away if i put a little pressure on the top, or if i bash it, but it soon comes back.

    any thoughts ... thanks

    Open the back of the old CRT television and carefully clean the dust and dirt away from the high-voltage components, usually located on the right side of the chassis looking at the back of the TV. The CRT holds a high-voltage charge where a big red or black wire connects to the glass tube so be careful. The area around the red wire rubber cup can be cleaned using a spray bottle of window cleaner, but again be careful not to get shocked... 25,000 to 30,000 volts can be present on the CRT
