  • hum in the transformer

    greetings to all colleagues!
    I have not specified the brand/model of the projector because surely it can happen in all of them.
    The fact is that my Beaulieu 708el for a month began to make an electrical hum in the transformer when it takes a while (approx 45-60 minutes) of projection. The soft "electric hiss" is appreciated when it is turned on but not playing (for example when you have finished watching a movie).
    Can it be a warning / symptom that something bad is going to happen?‚Äč

    PS: I use the google translator, sorry if there are things that are not well understood!

    Hi Arnau
    Providing your projector is running ok you have nothing to worry about. Transformers do hum it is normal, however you could check the fasteners holding the transformer down , if they are slightly loose the hum will be more pronounced. I am sure other members will add more information to your post.
