Pioneer pdp-436xde when I turn on the tv the seperate media reciever flashes from blue (on ) to Red ( standby) about 9 or 10 times ( the tv stays on blue and comes on. After the the 9th or tenth flashing of the lights on the media reciever it shuts down to red ( standby ) and the tv also shuts down to red standby. it is not an external cable issue as I have tested with new set of cables. regards Roger

Hi and welcome to FixYa,

Almost always, a blue screen on a TV display indicates a video mute, there is no intelligent video signal detected. Additionally, this would refer to the Media Box in your Pioneer. Initial suggestion would be to disconnect/unplug all connectors to & from the display unit and the Media box, leave then unplug for an extended period. Should your concern be a system glitch, then the unplug would simulate a reset to revert the units back to factory defaults. Pls give this a try.

A friendly reminder, most Plasma TVs (to my knowledge) do not react favorably to constant powering off then on then off again. Additionally, when trying from the unplug condition, try the other connectors/jacks than the ones usually used.

Post back results/updates. Good luck and thank you for using FixYa.

    Pls include the power plug to the mains/wall outlet. Leave the unit unplug from the mains for an extended period of time.

The issue is either the external receiver or the input board on the TV.

Test the TV on a different receiver, if it works fine , get a replacement media receiver.

Did you try using different input/outputs? It's worth trying, mabey one of your board capacitors are loose.

You are having a problem with the convergence circuit. Since it recovers, I would first resolder the connections on the convergence ICs. These are large black ICs attached to a heatsink and will be marked STKxxx. Try resoldering and report the results here.

    What's the typical monthly tab for a cable card?

  • mohammed marika thambi
    mohammed marika thambi Jan 31, 2009

    I have my cable box set to widescreen viewing (16:9)



    -Next to that setting I have the 4:3 material being stretched



    -I have 480i 780 1080i selected



    Do these settings still allow me to manipulate the way the screen looks
    by way of the pioneer remote. Basically, letting the TV rather than the
    cable box do the screen changes? I dunno I'm getting some 4:3 content
    with both black and grey bars but can't zoom the channel. Just wanted
    to see if I have things connected right



    D-Nice...anyone?



    Those setting are for an Oppo 971H dvd player *ONLY*. Here are some corrected settings for your 8300:



    Main Menu

    AV Selection: User

    Contrast: 32

    Brightness: +1

    Color: -13

    Tint: 0

    Sharpness: -3



    Pro Adjust

    Pure Cinema: Off or ADV



    Color Detail

    Color Temp: Low



    CTI: Off



    NR

    DNR: Off

    MPEG NR: Low



    These settings have no effect on picture formatting. Make sure you have
    auto size in the menu turned off or you will always get bars on the
    sides when watching 480i pictures.

    About 24 hours. Keep an eye on it. Sometimes it will stop and go to a
    light gray test pattern.....well it did when I had my 930.....just a
    heads-up.

    Did you sit around for 24 hours and just keep switching it back to the
    wash screen? Its changing to the grey screen every 20 minutes

  • mohammed marika thambi

    Mirrors out of location. But it usually throws the picture off
    center, also. This can be caused if the set is dropped or kicked badly.



    TWO: Out of focus. Can be caused by drift of the circuits or from a
    malfunction of the video drivers. You can check this by going to the
    crosshairs and see if the lines are sharp and narrow. If not, then the
    focus is off badly - most likely the blue gun. You may be able to set
    the focus and other levels for brightness and contrast and color to
    optimize this weakness as these are all somewhat interrelated,
    especially in the extreme settings. You can make adjustments for these
    above what is available from the OSD by getting into the service mode.
    See this web site for instructions on how to enter it. http://www.fixyourowntv.com/servicemenu....



    THREE: Worst case is the blue gun or projection tube is failing and
    needs replaced - which I don't recommend due to the very high cost of
    doing so.



    FOUR: And it is possible the blue gun/tube has been knocked out of alignment by dropping or moving the set.



    I favor the focus adjustment as the first remedy to try. You can do
    that yourself. But if it turns out the mirror is out of location or
    the blue gun is defective you will need a technician for help on those
    items.

    you are pretty sure that it is , in fact, IR and not burn in. I stayed
    up for about 14 hours doing the screen wash thing, then i got tired and
    had to shut off the tv and take a nap. Now I am back up and going to
    start it back up again. Should I already be seeing a difference? Can I
    just watch tons of Varied Dvds/HD TV etc to accomplish the same thing?
    I appreciate your help, It's just difficult to not use the tv for 24
    hours when I just got it.



    Check it and see if the IR is gone (it really should be).

  • mohammed marika thambi

    Watch only full screen programs with a contrast setting of 25. Also turn the power save mode to save2.

    You will need a SCART to SVHS
    adaptor (and cables) to feed both an SVHS cable and the red & white
    RCA audio cables into the Hauppauge card. Pay a bit more and get good
    quality cables, avoid the typical ‘wet pieces of string’ often bundled
    with most components. Don’t pay hundreds, but a few tens are worth the
    investment. But that can wait, anything will do for now. The
    improvement is only subtle to most eyes and ears, but it’s there, and
    if the quality is lost at this source stage, you can’t get it back.
    (Can’t polish a turd)



    You will probably want to use the other SCART plug
    on the Foxtel box and go directly into your TV set. Depending on your
    TV and Audio Setup, you may also want to run the digital audio out from
    the Foxtel box (or the analogue outs) into your TV or stereo. This will
    enable you to watch Foxtel without going via the MCE box in times of
    trouble, or when you want to use the ‘Red Button’ interactive features
    (more on the red button issue later). I haven’t used the direct
    connection to my TV for ages, but it’s a good option to have, and only
    needs another cable.



    The Foxtel box has a setup menu which allows you
    to access the preferred output video type. (Setup-System Setup-System
    Settings-Picture Settings-Video Output). It’s important to note that
    this option will affect BOTH SCART plugs. So if your MCE box is getting
    a SVHS signal from Scart 1, your TV will have to also have an SVHS
    input via Scart 2. There is also a composite video output on the Foxtel
    box, so you’ve got a choice of what to use, depending on your setup.
    Just remember that signal quality improves in this order… RF (aerial
    plug type), Composite (PAL in Foxtel talk), SVHS, RGB / Component. I
    haven’t seen any MCE tuners that accept an RGB or Component input, so
    SVHS is your best option.

Hi I have a Pioneer PDP-436XDE its over 3 years old and has worked perfectly until today when it switched itself off and would not switch back on. Ive unplugged it from the mains and left it for some time...


The reason for your tv not switching on properly may be due to

The main filter capacitor or other filter capacitors in the low voltage power supply is dried up and this can cause all kinds of regulation problems.

The power supply regulator is defective (or marginal) allowing excessive voltage on its output and then the X-ray protection circuitry shuts you down.

blue or red colour may be due to fault in chroma decoder circuitry.

I have a 56" samsung rear projection tv that won't turn on. the red standby light is lit and when i push the power i hear two clicks and the green timer light flashes quickly then the green led stays lit...


I suspect you probably have a bad LED assembly. It could be either the red, green or blue that is bad and give you the same symptom. The problem is locating parts for it as it looks like the light engine is no longer available. I would have a technician look at the TV to verify this and what parts are needed for repair.

Pioneer plasma media receiver problem



The Pioneer multi media reciever box is only serviceable from the manufacture. They should have authorized service reps that they equiped to do service for Pioneer devices. They normaly change boards to service it. The regular service man would only be able to fix a simple cold solder connecton or fix some other simple part of it.

Contact the place where you bought it to find out about servicing it. You may find it cheaper and easier to simply replace it completely. It is very possible that there is no service support for this box. Get an estimate before accepting to service it.

Most of the small electronics of today are throw-away anyways...
