I received a Sony BVM-20F1E earlier today and need some help:
The monitor emits a quite loud buzzing noise, it immediately struck me when I first powered it on.
I let it run for about an hour now and the buzzing noise is still here, doesn't seem to go away.
I think I won't hear it that much while playing games (except during loading times) but I'm still worried about it.
I made some research about the noise but found mixed opinions, in my case the sound itself isn't really suspicious but I find it loud...
I have owned many CRTs over the years and I've never had a CRT that loud.
Here is a short sample of the noise (hard to pick up with my crappy camera but it really is loud to me):https://www.youtube.com/watch?v=pQH6WLA3C3s
The noise isn't always that stable/consistent, sometimes there are patterns and it gets "faster" like a bomb that's gonna explode, then eventually slows down.
I'm not sure but I think the sound is coming from deflection or power supply boards.
Another thing I'm worried about is that the deflection module's heat sink is really hot (it took only a few minutes to get hot).
Is that normal? My Ikegami never gets hot and is dead silent...
The BVM has around 29k hours of operating time.
Any insight would be greatly appreciated
Hopefully nothing's wrong!
