I am trying to find a part number for the clear prism that sits over the emmitter diode on model HSU520 mitsubishi vcr.it sends the light to the end sensors. I faxed mitsubishi twice for this , and they faxed back a blowout for a different model that doesnt use the prism both times. any help would be appreciated, Gary Gary Chambers Chambers T V Bradenton,Florida Since 1982 Help make your TechAssist online repair tips database better!
