    InFocus SP 5700 and whine

    Hi there,
    I have in the past few weeks picked up a high pitched whine from my PJ.
    It only comes on when I feed it a signal. If it is on and the Player is not playing, the noise is not there. As soon as I play a disc, or feed a signal from the satellite receiver, then the noise starts.
    After about 30mins if I continue to play the disc, the noise then goes away.
    Any thoughts? Any similar experiences?
    Pls. help as the noise has now become a distraction while it is there.
    George. :M

      I have a SP5000 and am seeing something fairly similar to what you're describing. If I turn it on, without any signal, it's as quiet as a projector can be. But, when there's any kind of signal, the fan noise kicks it up quite a few notches, and suddenly becomes a mini leaf blower. I haven't noticed what you've noticed, where it gets quiet after about 30 mins, it just stays loud until I turn it off. I do have both the component and DVI input occupied and it didn't do this loud fan noise, when I only had component connected. For my SP5000, there's not much of a whine, but more of a loud "whoosh" noise from the fan. Really irritating.

          I have sent it in to the local dealers/importers and the first thing they asked me, have you serviced it every three months?
          If you haven't then the warranty is void. My dealer took the matter up with them as he had never been told this.
          Am waiting for a respones from them now. I suspect it is the colour wheel.

              well then it'll be strictly a DLP matter, 3 chip LCD designs like the SP5000 don't have any color wheels. I believe it has to do with the weather getting hot the past couple of days. Next time I use it, I'll make sure the air conditioner is on, and see if the fan kicks up louder.

                  I also had thought that it had to do with the heat, but Infocus got back to me yesterday and said it was the fan and not the color wheel, that was on its way out.
                  They will fix it as it is just under the guarantee, but it will take 4weeks, since they have to get the fan from the states.
                  4weeks!

                      I've been curious whether or not people have had problems with color-wheel bearings....

                      Fan bearings go even easier.

                          Infocus got back to me today, it is not the fan but the colour wheel(as i thought in the first place). It will still take 4weeks, but they will give me a loan unit. :T

                              Ref 50 processor whine???
                              by RedStep
                              I have been reading about the coveted Ref 50 having noise at low volumes. While some can live with this, some find it annoying or unacceptable.

                              From what I can gather, it is the absence of the mute circuitry. Now when you add volume, you can't hear the noise. I have also read that one...

                              the whine of RMB1075 during shutdown
                              by csuzor
                              Has anyone noticed that there is a high pitched whine from the surround right channel from the RMB1075 during shutdown from the trigger? Nothing from the other channels, just sR, and very repeatable. It's like a capacitor discharging itself, just as the red lights go out.

                              Don't worry...

                              Price Point of the Infocus SP5000
                              by ktaillon
                              Infocus is selling their Sp5000 for $999.00 after a $300.00 rebate. I've been waiting for the price of the Sanyo Z3 to come down a little more but now the SP5000 seems like a good deal. The only problem is the 1yr waranty for Infocus compared to a 3yr for the Sanyo.

                              Any thoughts - pro's...
