Question about Projection Televisions

2 Answers

Mintek DTV-323 32 in. LCD Television TV/DVD Combo The picture started out by being distorted (bright, florescent colors and eventually got darker & darker)now; (the next day) I keep loosing both the picture and audio and see only a blue screen with the following message in the upper right corner of screen (YPbPr NO Signal). I have it hooked-up to a moxy box but I believe it is the TV not the cables moxy box. The manual doesn’t mention this type of problem under Trouble Shooting. Thanks, Diane dianedavis13@hotmail.com

    with the blue screen do you see any kind of error message or any blink code?

    if so we can solve the error very easily

    More than likely its a vertical scan failure, you would have to check for that

    YPb'Pr' is analog component video. This is what all "component video"
    connections carry. Many devices have this labeled as YPbPr, which isn't
    technically correct, since it is a difference signal (which is what the
    prime marks apostrophes mean)


    How do I do that?

  • dianedavis13 Oct 22, 2008

    Shoud I do the following:


    Position Reset

    1. Press / to select "Position Reset" in "Screen" menu.

    2. Press OK to activate the position reset, the value of horizontal position and vertical position

    return to the default.

    3. Press TV MENU to exit

Check all cables and connections. Start unplugging power cable for ten minutes and see if this clears the error message.

    Try also changing the video input source selector, using the option on the TV remote.
    If you are not using YPbPr (component video cable) connector to hook up the receiver box, then that is the reason for the error message.

    Here is the picture of a component video connector:

I have a phillip magnavox big screen tv it works fine but the color is too dark i think i need a picture tube


If its the one indicated here or one like it :

The picture tube type (CRT) rear projection tubes require annual cleaning.

With set off and back removed locate the three large black lens atop the chassis--hard to miss them.

The are the red, green, and blue tubes and are your light source for the picture---------if dark and they are dirty or dusty the picture will be darker and not as sharp or clear as it once was..

spray some glass cleaner on a paper towel and wipe them clean.

Do not touch anything else in set and do it with set unplugged.

put back cover on and see if picture is noticeably improved; if so do it once a year or more if in a dusty place.

Let me know if you have questions.

How to fix my hitachi 65 tv


If you are saying that the picture is getting darker and you have already tried to adjust the picture through the menu feature on your TV then it is more than likely the cooling fluid around the CRT tubes. Over time the fluid in these tubes gets cloudy and causes your TVs picture to become dull and distorts the color. You can google tv repair kits .com and I believe they will have a kit for your model.

I have noticed the screen is now not as bright as it use to be, still works just not bright. A darker look is the best way to describe it


Hi,

The most common indications of a weak bulb in a Sony LCD Rear Projection TV are:
  • Dimimage with low brightness and contrast.
  • NoPicture, Dark Screen.
  • Shadowsin Image, sometimes circular.
  • Intermittent Shutdown.
  • Fluctuating or Flashing Brightness.
  • Longerthan Normal starting time.
Also check for distortion caused by Optical Engine Failure. If any of these faults are present, bulb will not fix. Sony Optical Engine Fault Gallery

Black/Green Distortion - Picture Quality - Wharfedale


This is no solution but a point in a probable direction.

A tech guy told me ALL the LCDs they have seen in their repair shop have "swollen" capacitors, this is due to voltage instability. Lowering the internal voltage regulator and replacing the swollen capacitors (which eliminate noise) apparently restores the LCD to new working quality. Without actually "seeing" my problem the tech said that should repair it. I have not tried this yet but eventually will begin that way.

Strange Image Flubbering/Convergence Problem, Flutters From Dark Picture To Light Picture.


you "tooled around with the convergence board" well this chassis has several problems if the convergence doesnt hold replace both stks resolder around that area per tosh tech bulletin the bright problem is probably the hyper module all toshs should be checked with toshiba website to see if they were part of the recalls for power supply caps
