Dont plug it on your tv the FLYBACK of your tv was defective. Need to replace your flyback or else more parts inside was damage. Bring your tv to a Electronic tech.

The slight flash on the screen is usually because the CRT (picture tube) is holding a better than average charge and this is what we call "pre-glow" The noise that you hear, is that everytime you turn it on or just after it has been off for a while? If only after the set has been sitting off for a while then your noise is the internal degauser for the CRT and that noise is 100% normal. The degausers in Sony TV's are so strong they usually make the plastic cabinet vibrate a bit.
