Question about Mitsubishi WS-55907 55" Rear Projection Television

2 Answers

When I turn on my big screen, I see the input channel (Input 1) in 2 lines: one line with red letters and one with green letters. I supposed my blue light is out, but it might be something else. How much would it cost to fix and/or can I do it myself? Please help!

This sounds like a convergence problem.

In the customer menu with the Mitsubishi remote select convergence and then advanced. You should see a grid of lines yellow in color.

If red or blue lines appear and are skewed and out of place you have found your problem.

I have step by step start to finish instructions for this type of repair in MOST OF THESE MODELS.


Let me know if it looks anything at all like the attached photos.

Hi
It's a good bet that the convergence chip is failing. The chip itself sells for $29. to $50. Replacing the chip is not greatly difficult but insuring that that is the exact problem is. With a good scope you can walk right through the circuitry on this set. I would recommend a reputable repair person. Note: anyone who can give you and estimate without going through the set and/or is willing to do the work in your home is worth bypassing quickly. Good luck

I have a hitachi rptv model #43FWX20B and the picture has a red tint to it. Opened back up and red green and blue bulbs light up. red bulb stays bright while blue and green go dim to bright as tv plays....


Howdy;
Since you don't have any white lines with the red screen/picture I would say that the red bulb (CRT) is conducting too much. There is an adjustment control for that. The 'sceen' control is behind the speaker cover and service cover. Turn red screen control slightly to the left until you get a good black and white picture.

Good Luck, Big Irish.

Faint lines show up when i get dark screens in movies


First check what color of faint lines comes then reduce Screen Volts in TV of that CRT (tube)
Take off lower front cover, speaker grille of TV, there you will see focus control block that has 6 control knobs, upper 3 knobs are focus adjustment of red-green-blue CRTs and lower 3 knobs are screen volt controls for red-green-blue CRTs. Turn screen volt control knob CCW to reduce screen volts of desired CRT.
Put TV on any free AV input so screen will be dark enough to adjust screen volts.
Thanks.

Screen is red with lines when channel is changed


If its a kp-51hw40 : go to an unused video input and look at the screen---if it is redish in the background with curved faint trace lines you have one of two things wrong; First: the red "screen" control may be set too high. Second: you may have a problem with the RED picture tube.


To try to adjust the RED screen down you have to remove the entire front grill plate on the front of the TV(some have screws on the back on either side that have to be removed---and then you should be able to pop it out. Behind it there is a masonite inspection plate held in with screws----Once you have that off look for a SMALL SQUARE BLACK PLASTIC BLOCK; it has 6 black adjustable controls---you have to use a flashlight and look carefully---one row left to right will be marked FOCUS--DON'T TOUCH THOSE---THE OTHER ROW left to right will be marked SCREEN; if you look carefully you will see marked by each r (red) g (Green) b (blue)
you want to locate the RED SCREEN CONTROL.

WITH the set still on a blank video input where you can see it clearly turn the RED Screen Control to the left until the lines and red tint go away---do this slowly and make sure you are adjusting the RED screen--not the FOCUS.


IF this has been helpful give me a vote here as I do this for free; yesterday I adjusted one of these in a home that was blue with the faint lines---about 15 minute job for me.

How do I get sounds when I use the red green blue rca hook ups?


The red, blue and green RCA hook up is just video. You must also use the red and white pair of RCA jacks for the audio. You can usually find the audio red and white jacks right below the video red, blue and green RCA jacks. Get yourself an audio RCA cord with the red and white connectors and run that from your video device audio output to the audio input of the TV that corresponds with the video input of the TV. An example would be if the red, blue and green are on the "Video 1" input of your TV you will find the red and white audio input for "Video 1" right below or right next to the video inputs.

The red, blue and green video jacks are called "component video" and they only have a video signal for high definition video, so you must also run a separate audio line for it. The same holds true for the yellow video RCA connector, that one is called "composite video" and it also has only a video signal with no audio.

I hope this helps, if so a "FixYa!" rating would be very much appreciated.

If you need more help just post your concerns right here onthis thread.

Blue Screen


Your blue crt has a short - you can verify this by unplugging the socket from the blue crt and powering up the set and you should see a yellowish looking picture with just the red and green crt's operating. You can try turning down the screen control pot (B) for blue with the blue crt on (just to the point where you no longer see retrace lines in the picture on a blank input)Sony has had a lot of problems with the crt's on these models and sooner or later all the crt's will fail - For a permanent repair all must be changed.

Changing the inputs


It might depend on the type of input. VCR often use A/V or component cables. if you are using AV (red, white, yellow) make sure they are plugged into the right input. if plugging in to a component (white, red, green, blue, red) make sure the yellow plug goes into the green input. If plugging in component make sure your red wires are not backwards. There should be a white and red together (these are the audio) and a green blue red together (these are video)
