Digitizer 4 Noisy Transformer

(1/5) > >>

kissfan113:
Got the battery replaced in a new to me digitizer4 today and powered it up for the first time, all very good except the transformer has a pretty good buzz going on, if I pinch the case right near the transformer area I can feel it but it quiets down, is this a common issue or a one off

rnolan:
Hard to say, I expect it wasn't buzzing when new.  I have an IPS33 smart shift that has the same buzz issue (and didn't when new).  If I take off the lid you can't hear it, so it's reverberating through the case lid.  You could try checking the transformer mounting points, maybe some rubber grommets on the mounting bolts may help?

kissfan113:
It’s worth a shot, the transformer has a pretty loud hum when the covers are off, which I’m assuming wasn’t likely when it was new, not sure if transformers would be available for replacement or not.

MarshallJMP:
Does the transformer gets hot after a while?

kissfan113:
I havnt run the unit enough as of yet to tell, only about 5 mins at most. I will get back with you once I have a chance to run it for an hour or so
