I had a loud fan problem on my Media Receiver (PDP-R04U) for my Plasma TV. I opened the top of the receiver to see which fan (there are 2) was making the loud wering sound. It wouldn't go on so I put everything back together (didn't touch anything) and now it doesn't work at all. I took it to the Pioneer local repair place and he said that I tripped a switch and he couldn't reset it unless I took in the large heavy 43' screen. It worked fine until I opened the set, Is there any way I can reset this switch myself? Thanks, JOE hello, i have the same problem but MR model is a pro-r05pu and i can,t get the display to turn on- the red lights on the display & MR along with the green on MR stay on (no blinking). the display model is a pro-435pu. any help will be very appreciated. thanks,
