SOURCE: jvc 52 inch tv. the picture on the upper left

Hi if your tv is a Dlp or Lcd it will be a problem with the light engine.Basically there's 3 chips green,blue,red that create the image and colors.When they start to go bad or melt you will get color discoloration on corners on the center.You will need to replace the optical block ,you can find it on www.discount-merchant.com www.shopjimmy.com or ebay .Have a blessed day!

I have a blue streak on the left side of my Hitachi ultravision digital TV. This streak is not solid but hazy and irregular in size.


projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Our 1991 RCA P52150CP rear projection TV has gradually been getting bright cloudy blue, slight haze around letters & shapes-(especially blue channel change headings) when first turned on and then it...


Hi

First check whether all the cables from your dishnetwork are fine and connected firmly.If yes then you'll need to pull off the front of the tv, behind the speaker grill there would be a panel. Remove the panel and check for a black box hanging over there. It has 6 controls on it, 3 are marked as focus and 3 as screen. You'll need to adjust the screen. If you turn these too high you can damage a tube. so we are doing real small adjustments. Turn the color off on the tv and adjust the red, blue & green controls up till you get a fine picture. Also adjust the focus until you get a clear picture.

And, if it doesn't resolve your issue then it is an intermittant blue picture tube, a bad blue driver transistor on the CRT board, a bad connection on the blue crt board, or a problem in the RGB coming from the video jungle IC. A set this age, most likely will run you about 300 to 500 bucks to have this problem fixed, unless it is the picture tube.

Please do accept this solution and revert for further assistance.

Thanks
Rylee

Mitsu #WD52327 DLP replaced bulb but hazy picture


Did you clean the small mirror. Dust will cover this mirror and give you a very hay picture. This is easy job and takes 15 minutes at the most. Someone posted detailed destructions on how to do this already if you look for it under WD52525 hazy picture.

Is my bulb going bad!!!!


Without seeing your Tv it is hard to say what is really going on.

The cloudy picture sounds like one of your "bulbs" needs to have it's fluid changed, not "bulb" replacement.

Rain bowing normally means convergence adjustment or circuit repair is needed.
