Question about Projection Televisions

1 Answer

Bought a new Sharp 46" HDTV. On HD channels only, the picture is sharp but the reds are brown in color and cannot seem to get any red into the picture. Flesh tones look brownish and not lifelike. Have tried adjusting everything from minimum to maximum. On standard TV channels reds appear fine only the picture is not sharp. DVD colors and picture are fine. Any assistance would be greatly appreciated. Thanks.

Picture is still sharp, but the colr red just disappeared from the picture. It all looks washed out. Any suggestions?


This set used an LED for the illumination source IIRC... a total loss of one color means the loss of one of the three LED's that drive the DMD module. In your case--the RED LED module --or it's driver--has failed. There is NO color wheel to deal with in this set.

I have a Sony, 54" Projection Screen HDTV that I bought in 2002. I believe it is a 1080i. When I am waatching TV, I notice that when the screen is mostly black, for instance a night scene, the black areas...


Confirm the actual model number as the one indicated in the title is not HD.

Some of these sets had bad picture tubes that on a black screen or blank video input may in your case show faint curved lines and or some color (red,green or blue) present in the background.

If this is the case there is a fairly simple way to attempt to adjust something for this--not in the customer menu but fairly easy to get at and try.


Most of these sets were KP51ws500, 57500 etc.

There is a wave in the picture only in the upper left hand 1/4 or the screen. The rest of the screen is sharp. You get the colors separated and thus double image.


Projection TV sets have several common problems listed below.

Problem #1) Convergence

Symptoms:

  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted
  • No Audio/Video - makes a chirping sound.
Example Photo:

Problem #2 CRT Fluid has clouded over.

Symptoms


  • Dull Video, Washed out
  • White/Bright looking video
  • Halos around objects
  • Red/Orange looking

Panasonic pt43lc14 no red color. picture is good. cannot get anything to look normal color after trying to adjust color/tint/picture etc. Have alot of blues and yellow, and brown. seems like no red.


It appears that your light engine is broken, I have the same problem. Have you recently changed the bulb with a non-panasonic part bought on the internet. I did this and think thats what caused the problem. I believe the new bulb burn at a higher temp thus causing damage to the Light engine filters

Dark picture


use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.

Sharp DLP No picture


i have a 56DR650 and it does them same thing. It is still under warranty but where i bought it, they said they can no longer fix it so they are giving my money back. the problem has to do with the color wheel inside.

Colours all messed up and reds dull look brown


You should first turn off all the color on the set, or play a b&w Tape or dvd. What were looking for here is, what the color balance or grey scale looks like first. If a B&w video or whatever looks true to grey and black and white then you have whats called croma problem in the color or video demodulator. My friend I wish there was an easy way to assist you in this type of repair but theres not, as it could be a problem in the video/croma demod section of the video jungle IC and this is not a user serviceable part or repair as thers several issues concerning Hi voltage as well as x ray radiation. Now if its a problem where the grey scale or the B&W is not true to color then theres a problem in the R G B driver circuits. Could be a simple drive adjustment or even a soft or weak picture tube. I hope if your not a tech you seek a pro to assist you in this troubleshooting as this could be dangerous for you as there are no user serviceable parts inside this set. Good Luck
