Re: RGB colours all over

It is due to magnetic effect in television due to problem in degaussing circuit. solution 1 remove the things which have got magnetic effect like speaker, phone etc. 2 change the direction of tv. 3 do not change the direction when tv is on. 4 call tech. to degauss it by using degaussing coil at your place. 5 it is not a major problem.

Purchase a Color Wheel & The Repair Job

My television is model Samsung HLM4365WX and the color wheel part number for that is BP96-00250A. This color wheel is used in many, many Samsung televisions, but you should confirm that your model is on the [affmask= BP9600250A%2FNew.aspx]compatability list[/affmask]

The Repair Job
  • Philips screwdriver, not too small and at least 5 inches long. There’s one screw that’s a reach.
  • Tiny (jewler’s) screwdriver. You may not need this. I needed it to get a connector off.
  • Tweezers. I needed them to get to a few screws in tight places.
  • Compressed air. I didn’t have this, but I wish I did. It’s dusty in there.
  • Pen and paper. I took copious notes. If you do anything that I don’t talk about here, you should write it down. I carefully documented every cable that I unplugged and every part I removed. Thank God I did that.
  • 1-2 hours (first time I did this, it took 90 minutes. Second time 60 minutes, with photography)
  • Nerves of steel and air conditioning. Don’t drip sweat into your television.
  • In this document, left and right are “stage-left” and “stage-right”, or the left and right sides of the set as you look at the back, facing your sofa.
  • Almost all of the screws are identical. You can safely keep them all in the same cup, or pile on the table, or carpet, or wherever you store the screws.
  • Don’t touch anything that looks like light will shine through it, like the projector lens or the colorwheel itself.
  • DON’T rely on this document entirely. Pay close attention and take notes or digital pictures.
  • If you were just watching your TV, your projector lamp will be HOT. Let it cool down.
1. Remove the back panel from the television set. The panel runs the entire width of the bottom rear of the set. There’s no need to remove the access panel for the lamp. That’ll come off with the panel. There are 14 screws.

Just unscrew the two brass screws holding it in. It’s on the right side of the TV. The screws won’t come out, just pull them out with the whole unit by pulling on the handle and sliding it straight out. Carefully store it somewhere safe.
lamp.jpg lamp-removed.jpg 3. Remove the panel on the left side by removing two screws holding it in place. Carefully slide it and the attached PC board out a few inches until cables stop you. You won’t actually need to remove any cables from this board to get at the color wheel. (Of course I removed most of them the first time.)
left-panel.jpg left-panel-out.jpg 4. Carefully note how the power cable is positioned in the set, and the route it takes out the back. Once you have done that, pull the power cord out of it’s notch in the bottom of the case. It’s blocking the next part that has to slide out.

You don’t need to take off the regular sized screws that fasten the back panel to the base. They’ll all slide out together. Remove the top two screws that hold the panel to the plastic case.
Center panel. The two screws on the bottom have larger heads than the rest. Remember that these go here. There are two more screws on the bottom that hold the vertical panel to the base. No need to remove them. If you do, things get a bit floppy.
6. Slide out the center unit slowly, just a few inches and take a peek inside as you do. It’s a snug fit, so you’ll need to ease out both the top and bottom at the same time. Some things to notice as you do this. Look at how the projector lens is fitted inside a foam sheath. You’ll need to put that back later, so take a good look.
projector-lens.jpg There are a few cables on the left side restricting it. You’ll need to unplug these:
  • blue/brown two-wire power cable. You’ll need to unplug this from the main set.
  • blue/white cable connecting to the left side. Squeeze the plug to unlatch it and remove it from the center unit that you’re removing.
  • Sensor switch on the right side. Unscrew this from the tv case bracket.
This arrow is pointing to two of the cables. Follow the brown/blue one to the other end to unplug it. Right behind this arrow is the white connector for the white/blue cable.
Here’s one of the screws that are different. Remember to use the smaller brass screw here later.
Now you can slide the center panel and all the parts behind it out of the television. If you didn’t remove any cables on the left panel, you’ll have to swing everything over to the left to clear the television.
open-tv.jpg Note: Steps 7-9 are removing the bad color wheel. I suggest doing these steps carefully, as if you were going to need to use this color wheel again. You never know if you may need to reverse what you’ve done.

further steps will be continued

I have a 4 year old WEGA Trinitron HD TV (model # KV- 30HS420) that over the last few months has been switching between full color and color missing green colorations. Most of the time now the full colour...

A good TV repair shop should be able to repair this but given the current price of flat panel TV's you might want to think about scrapping it.
I was a little confused about your description of the fault, one colour disappearing is in a very different area of fault from all colour disappearing. Does it flash into correct colour momentarily if you fine tune it? Is the picture as far as you can tell black and white or does it have a strong colour cast on it where everything is for example reddy or bluish etc?
I hope I have been of help but please do not hesitate to ask if you have any further questions.
I appreciate your vote if you appreciate my reply.

Sony KD-36XS955 36 inch wega televison has yellow caste, cannot adjust to get any blue color. Has same problem on both cable and Directv. Unit is about 3 years old.

It is one of two issues, the blue video driver is defective, or the blue gun in the picture tube is open. This will need a tv tech to varify the problem and suggest a course of action.

Wierd Pink colour in corners when on AV

Do you have any speaker alround? Or something with magnet material, on the top?, if yes, move out . If not.......... I recommended this, But!! be carefull!! I dont responsability for incorrect damage ok?. With a speaker or magnet , pass alround area on bad color, just pass quickly from the bottom to top.....Be carefull!!, don't do this on other area, will make big shadows and bad picture... If still there, maybe tv need work on degaussing area.

Error with red color

i've never had to fix this problem before, but give this a try, it might work. remove the front bottom panel of the tv, their should be 2 to 4 screws then the panel should come off. it might need a little prying & sometimes they use velcro to hold it in place along with the screws. now remove the small plastic or wodden panel, another 2 to 4 screws. now in the upper right side you will find the screen/focus block ( 6 controls). i think the top 3 are screen & the bottom 3 are focus. you will need to adjust the screen control., use a flashlight to read it. now the center is the green tube, i do not remember if the red is to the right of left. the screen control is like the master brightness, which sould help with the low sensor output. if you turn up the red too high you will get small red lines on dark picture/or in a dark room. good luck.
