Every time i use my tv for a short period of time start a background acute noise.... it`s very disturbing noise and in a very high frecuency
This is a problem in almost every tv set made as whats causeing this noise is a loosly wound coil or transformer thats vibrating so fast cause theres a tiny gap in between the windings that it makes a noise or "sings". Sorry to tell you to fix this problem could be a hit and miss thing as it could be in the deflection yolk on the neck of the picture tube ,the flyback transformer, the horizontal driver or power transformer or one of the many many coils on the circuit board. If you have no training on tvs then this is not a repair you should try. But to find out where the singing coil or transformer is could be very time consuming and if you do find it theres only a few small things you can do to try and stop the singing. Like sqeezing around the top and the bottom of a coil some silicon and letting it dry before you turn on the set or for a transformer you can take small homemade shims and stick them around the core or underneath but dont break the core!!! other then this simply replacing the part works most of the time too. Good Luck
