SOURCE: colour problem on rear projection tv

This might be something really simple... In a large number of DPTV310 chassis, of which this TV is, the yoke connections where put in place with black electrical tape just below the retaining rings. Job is to loosen the rings, remove the tape and push the yoke back in place and tighten down retainer.. Be careful not to throw off the tilt of the yoke. The adhesive on the tape, over time, gets hot so many time it becomes slippery and allows the yoke to fall away from it's position dulling the look of the image (or focal length) causing the problem you're describing here... It also throws off the convergence - so in attempting to converge it just looks worse. Good Luck Bill

SOURCE: My Sharp LCD 26" TV

the problem with LCD tvs are that they have back lamps that shine thru the LCD sceen. the job of the screen is to block the light of the different colors to make the picture. the problem is that the very thin screen can not block all the light. if the set has a back lamp setting turn down the back lamps and adjust the brightness control it should help a little. you my notice that the blacks and dark sceens look better when the room is fully lit and look much worse in a darken room.

Reset will not cure a convergence problem.

this model (ws-65711) uses a single convergence chip located on the middle circuit board (see photo).

If convergence is skewed and will not adjust in customer menu the chip needs to be replaced.

Good news: I have start to finish, step by step instructions for this repair in this set. They tell you everything you will need and exactly how to do the repair.

No two sets with convergence problems will look exactly the same but I will also attach a few photos of this kind of trouble.

If the photos or what I have told you told you something you did not know and you want the instructions (free) rate this solution as very helpful as I do this here for free.

Rear-Projection TVs have a lamp, which picks up the picture and projects it on the TV screen. A burned-out or connected lamps are two of the most common problems for Rear-Projection TVs. First, you will want to confirm the bulb is still good. If the bulb is bad then then replace it immediately. Second consult your user manual and verify the lamp and lamp cover are installed properly. Most Rear-Projection TVs have warning light which notify you when there are lamp problems. Again consult the user's manual to see what each light means.

Overheating

Temperature is a common reason why many Rear-projection TVs do not perform well when they get to hot. You may start to see your TV shutting down automatically when it overheats. Here are a couple of things you can do to prevent overheating. First make certain any TV ventilation ports are free and clear of debris and dust. Second make sure the TV has enough room for airflow. Third, the temperature in the room should be around 72 degrees. Due to the high degree of heat generated by a rear-projection TVs, it is not advisable to watch TV on a hot days when you don't run the air condition. This could cause damage to your TV.

Configuration Problems

Improperly configuring TV setting can cause problems. Verify the TV settings are set correctly. First, brightness and contrast should not be set to high or to low because this can cause poor picture images. Second, adjust the color on the TV when the picture displays colors poorly. Third, if you are having sound issues then check to make sure the volume is not muted or turn down all the way.
Reset component settings. Usually, the problems you encounter with a projection TV may be resolved through the resetting to its factory settings. If you experience inaccuracies in the color, reset the television's PerfectTint/PerfectColor capabilities. Simply press the Menu tab and then highlight "Perfect Color" using your right key arrow. After this, press "Enter" and then "Reset" in order to reset to factory settings. If you have audio / video problems (VCR or DVD player), simply press "Menu" and highlight the "Reset" option
If the problem persist you have problem with power supply see the video attached.

Do not have copy of owners manuals and user guides


Problem is likely with a setting at the picture source. Make sure you only have enabled the setting your TV is capable of (480i, 480p, 1080i, etc)

Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Samsung Tantus (SP-43J8PF) Has Green Tinge - Easy fix?


You may try to get into the service menu and adjust screens/drives level(procedure below). But first turn the color off completely and adjust you brightness to mid-range, what you`ll want to do is a grey raster or bring it as black and white as you can while adjusting the red/green /blue guns or tubes. Also get a piece of paper and pen because you`ll want to record the original values of the items you may change. You want to go into the adjustment menu. Hope this will help Good luck
In quick sequence on the remote press:
MUTE - 1 - 8 - 2 - POWER buttons.

The TV will turn On with the Service Menu displayed.
ADJUSTMENT - TEST PATTERN - SET OPTION BYTE - FACTORY RESET

Select the function and use the VOL+ button to enter.
Save settings and exit by pushing MUTE twice then POWER .

The problem is that everyone has a different "taste" when it comes to these settings. I like to turn the color all the way down to start with. You should (if the set is factory adjusted correctly) have a black and white picture. If it's not B&W, then there's something inside the set that needs adjusted and you should get a service call. Then I adjust brightness and contrast to get the best B&W picture. Then I turn the color up until I'm happy with the color level, then I adust tint.

Hope that helps

Bad ghosting of all colours


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu.
