Hello:
I am checking out my 2235 (US/AN version), and apart from some other idiosyncrasies, that I will leave for later, the unit is making a quiet, but very unpleasant high pitch "whine" after about 5-10 min of warm-up. The best I can say it is coming out of the power supply portion, but the source of the sound is difficult to pinpoint for certain...
What would be you suspicion? Is it a PSU showing signs of fatigue? Recommended steps? Time to recap?
Not sure if this is relevant, but 2 out of 3 small neon bulbs close to the PSU are briefly flashing, when the power is being turned off... Switch-off voltage spike protection possibly?
Advices would be appreciated.
DS
