Hi, I'm new. Every once and a while my Hitachi shutters, I suspect it isnt recieving sufficient power. I'm using this surge strip: radioshack.com/product.asp?catalog%5Fname=CTLG&product%5Fid=61-2433 I noticed on the plug that the set draws 7amps. Is there any UPS I can connect to this to prevent that from happening? Is it a problem with the set? Also what can I use to clean the screen? Any specific solution?
