This is a convergence problem that can be as simple as poor solder connections to defective convergence ICs. If you can update this with the model of the set, additional details and instructions can be provided.

JUST WANT TO KNOW THE COLORS OF THE RAINBOW AND WHAT ORDER?


Although I am not sure what this has to do with dryers, the color spectrum of a rainbow runs from purple to yellow. The visible spectrum runs from black to white with ultraviolet and infrared beyond the visible spectrum. Purple, violet, blue, red, orange, and yellow are the colors in a rainbow.

After changing the ink catridges and resetting the drum fuse lately (note: it is known that the fuse will be blown off after certain number of prints but otherwise is in good condition), my Epson Acculaser...


The repeating image is a ghost image, and here is described what it can be. Probably if you solve this, you also solve the red-dot problem. If possible, I would suggest to replace the wiper blade.
Repeating images on laser printerThis likely means a faint ghost of the main printout at a distance equal to the circumference of one of the rollers or photosensitive drum.

Depending on where the problem originates, this could be a bad wiper (cleaning) blade, faulty corona, or incomplete fusing.


  • If the distance between successive images is equal to the circumference of the photosensitive drum, it is a wiper blade, erase lamp, or corona problem.A residual latent image or residual toner is sticking to the drum and not being properly cleared.

  • If the distance between successive images is equal to the circumference of one of the fuser rollers, then the fusing may not be complete due to damaged rollers or an incorrect temperature setting.

It is easy to determine where the problem is located: Interrupt a printout in mid-stride (where part of the paper is between the toner/developer and fuser. If the un-fused image has ghosting, it is a fault in the area of the drum

Images have some ghosting, but convergence lines seem to be OK. For example, white images have a yellow shadow to the right of image. Any suggestion?


Some easy steps to determine where and what your problem is:


1) In customer menu select convergence and then advanced (done with the Mitsubishi remote) look to see if grid of lines straight and if "yellow" is seen there.

2) Look to see if it happens when DVD etc played; If only on component from a cable or sat box but not on tuner or DVD inputs it is not the set.

3) Go to a channel that is in black and white and in customer menu turn COLOR all the way down: is problem still there or not?

If problem is not convergence and is present on all inputs it will be a problem with one of the three CRT boards; they plug onto bottom of each of the the three picture tubes this set uses; yellow suggests a problem with the blue one______loss of blue may give you a yellow smear around things/ red and green equal yellow.

You do not need to take the set apart for this.

Let me know what you find, the more you rule out the easier it is to know where the problem is.

Video distortion


You need to take your tv in and have the picture deflector re-aligned.  This doesn't cost much, My dad had to do that to his a few months ago and it cost 30 bucks.

Kp-46wt500 shadow and slanted images with rainbow colors


Here are some of the most common symptoms and example photos of a convergence problem

  • 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.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

Mitsubishi WS-65511 Rear Projection Big Box TV resets with a green flashing light every 5 minutes, Then works fine for 5 more minutes (perfect picture). Acts up worse when cold. Warm it up Works hours It's NOT the DM board caps. I've already replaced the DM caps twice. Not the problem. No repairman will look at the set. Too Old. So am I. I could repair it with help. The power supply must have a safety circuit that will shut down & reset if too much draw. I DON'T have a diagram. I'm not sure how to trace it . Which board? If I unplug boards one at a time, Will it damage other boards ? I know it is NOT the 7 DM board caps everyone keeps telling me. I see no burn't parts, No bulging caps. Tapping on components doesn't reset. What kind of component would act up when cold , But not overdraw when warm? This set has the best beautiful picture when it runs. If you can get past the resetting every 5 minutes for the first hour, You can watch it sometimes for 20 hours. I've left it on at night & it is still on the next morning. Change the channel Or raise the volume, And off it goes. Once or 10 times, Keeps resetting. Then on for 4 or more hours, Maybe. I can't afford a new one. It works GREAT ! when it works. I've notice that even when the set is turned off, The green light starts flashing (resetting itself while it's off) , Then stops. Once in a hundred times it will kick off the breaker & you need to push reset with a pin on the front panel next to the green light. It's probably a 10 cent resistor OR a $ 1.00 cap. If I only had someone with more knowledge than me to help. I know how to use a meter & read a schematic. I built a Heathkit 25"TV in the 70's & all my novice ham gear. I'm 64 & not familiar with digital circuits. Can someone help PLEASE ?
