Question about Mitsubishi WD-62725 62" Rear Projection HDTV-Ready Television

1 Answer

TV shuts off on it's on after about 20 - 30 minutes of play

I initially thought the problem was signal related, but have tested three different inputs and none of them solve the problem. TV will freeze then shut itself off.

Freeze like the picture is in pause?

picture freezing is desired function on the remote and handled mainly by the "picture and picture" circuits. but the video that is involved and processed there is handled by many circuits and microprocessors.
what you describe is an intermittent heat related problem if you almost can set a watch to the the shut-off time. you can feel, if your a tech, what part is running hot with a finger or start freezing a suspect part with freeze spray and see if stays on long past overdue. make sure your vent holes in the back are not covered and keep the back at least 1/2 foot from the wall.

Samsung DLP 72" HL72A650C1F keeps turning off amd on


Hi,
Did you buy the original lamp?
If the problem is related to the lamp door switch, you will get a different error instead of lamp LED.

Do you hear the color wheel spinning?
Again, if it's a color wheel problem the error will be different!
My good guess is the lamp but, it could be the ballast or both.

Best of luck

Mitsubishi Rear Projection WS


5ebe434.jpg A projection television and a convergence control method thereof are provided. The projection television, which magnifies images displayed on cathode ray tubes (CRTs) for the colors red, green, and blue using lenses and projects the magnified images onto a screen, includes a convergence control apparatus capable of adjusting the convergence while an input image signal is displayed, the convergence control apparatus including: an image signal decoder which processes the input image signal to generate a data signal, horizontal and vertical synchronous signals, and a start signal indicating the start of either the horizontal or vertical synchronous signal; a convergence control unit which normally projects an image signal output from the image signal decoder onto the screen and performs convergence control using a predetermined region of the screen displaced from a visible region of the screen according to a convergence control command; and a main microcomputer which inputs the convergence control command to the convergence control unit when the start signal is input from the image signal decoder, stops the convergence control when a completion signal is input from the convergence control unit, and performs a control operation to continuously display the image signal during the convergence control.
.
the pro in convergence control circuit only..so better change tat..

What does hdmi is blocked mean


Hello!
HDMI blocked could mean, that one or more HDMI inputs are turned off. In WD- series DLP TVs it's possible to disable one or more inputs, which are not to be in use, to speed up signal source switching. Most of modern sets are constantly monitoring inputs and automatically recognizing "plug"n"play" signals. blocking any input would not cause TV to shut down.
Yellow(amber) light means: lamp door interlock switch is off or malfunction. green blinking: set is initializing, about to begin normal operation. So: quite possible that lamp has been replaced incorrectly or door is not tight intermittently. Last possible issue: door's interlock switch is bad. Take lamp door off and you will find the switch with blue lever on the left side of the door inside plastic compartment. Push it with your "pinky" or pencil carefully, then ask someone to turn set on. Make sure, yellow light is off, before do so. If set starts normally, observe lamp's activity: it should stay on and getting brighter, while you holding switch. If lamp stops working, while there is no "amber" light, then TV shuts off, red blinks, lamp is bad. I just had to replace lamp twice, due to defective batch of lamps with housing. 3rd time I replaced bare bulb and it solved the problem. But there was no "amber" issue!
good luck,
Alex.

I have a RCA HD52W59 TV. Shuts off automatically.


Power supply is my initial thoughts, but then again it could be that one of the three CRT's tubes has an issue.
My thoughts is that it would be best to bring it to a good TV repair shop.
Why spend money on a power supply and then find out it's a CRT.

Auto sensor finding wrong inputs, cant find good component signal


as any new technology TV as yours. your tv has a microcomputer (kind of mother board) that is not detecting your video inputs or any information to control. The initial set up cannot finish and there it go the answer: you have a blue screen or green with the bars (of course this is another area but still related with the control of video that it is another funtion af the main board). So the outside of the tv is ok now because you made many actions directed to troubleshoot conections, and there are fine, but the problem isn't there this problem is at the board level of the tv. technician is needed.

After playing for a while DVD will stop for a few minutes and than start playing again by itself.thank you


Good Day, amchel2;
It sounds like the 'DVD" player may be the source of your concern, and not the TV. Try using a different disc or input to the TV, if different input and okay then bad TV input. If different disc then okay, then bad disc. IF no,no on both then bad DVD player.
Good Luck, big IRISH.

Tv shuts off sporadically, and now won't recieve any video signal


Check the solder on the vertical output IC this is a common problem and can cause loss of video while sound remains and often will shut the set down with a vertical deflection error
