Heres the time line, a little over a week ago I first notices a bit of slow downward drift on the filter 1 cutoff knob. This has been happening since. In addition to eventually fully closing if I'm not attentive, it also hijacks the screen. Then yesterday, it started halting and jumping the filter cutoff level. Then tonight, the screen would shutoff very quickly after turning it on, and not come back on until I repowered up, with the screen going out winthin a minute or two consistently. HOPING I dont have to send it to San Fran....
