Question about Mitsubishi WS-65809 65" Rear Projection Television

2 Answers

Mitsubishi Rear Projection WS

Have bent lines, all three color not aligned, 3d effect.
Just changed the two STK convergence IC. Is there a convergence amp or convergence generator that needs changing? if so where do I purchase one? I'm told the problem could be a pico fuse and not the ICs.
Is it possible the two new ICs were blown immediately because some other issue was not first resolved such as the pico fuses or resistors?
What do you suggest?
Thanks

Mitsubishi Rear Projection WS - 5ebe434.jpg A projection television and a convergence control method thereof are provided. The projection television, which magnifies images displayed on cathode ray tubes (CRTs) for the colors red, green, and blue using lenses and projects the magnified images onto a screen, includes a convergence control apparatus capable of adjusting the convergence while an input image signal is displayed, the convergence control apparatus including: an image signal decoder which processes the input image signal to generate a data signal, horizontal and vertical synchronous signals, and a start signal indicating the start of either the horizontal or vertical synchronous signal; a convergence control unit which normally projects an image signal output from the image signal decoder onto the screen and performs convergence control using a predetermined region of the screen displaced from a visible region of the screen according to a convergence control command; and a main microcomputer which inputs the convergence control command to the convergence control unit when the start signal is input from the image signal decoder, stops the convergence control when a completion signal is input from the convergence control unit, and performs a control operation to continuously display the image signal during the convergence control.

the pro in convergence control circuit only..so better change tat..

It's a convergence problem, as mentioned go into Settings in the TV menu and select Convergence if Auto it will do it when you select this. If not it will ask you to do "Multi-Point Convergence" which will bring up a huge grid on your screen. You must use the TV remote and using your up and down and left and right buttons to place the "curser" on each grid and adjust the Red and Blue on each point till you get a pure white "grid point" Think of the picture as split up into say 72 different puzzle pieces and when you adjust each piece it fixes that one piece of the puzzle or screen. You want all lines to be pure white and by looking at the grid if you see either blue or red on the side of the white line, you want to move the right, left, up or down button so that the blue or red line gets back on track with it's corresponding white line grid.

It sounds complicated but you will get it after a few seconds of playing around with it. Convergence should be done after the TV has been on for at least 30 minutes and should be done at least once a year (twice would be better at minimum) You see the problem with RPTV is they use three color lenses and as you watch TV, the lenses over time get out of alignemnt and need to be readjusted to get a clear sharp picture.

I adjusted a TV once that had never been converged in ten years and it took me over two hours to get all 72 points back on track, once done you will notice a way sharper picture and the colors won't be off kilter.

It takes time, but once you get it, you'll get it. I converge mine once a month and it takes me about 2-3 minutes to do the whole screen because I keep up to date on my 58" Pioneer RPTV.

    Grab your remote, go to your "Setup" menu, and choose "convergence". If
    there is an "Auto convergence" option, do that and it should fix
    itself.

    What happens is that the red, blue and green projection guns (lamps)
    get knocked out of whack if the TV is moved. Whenever you see red, blue
    or green lines, it means that the projection guns are not aligned. To
    realign them, you COULD do it manually, but I wouldn't suggest it
    unless you know what you're doing. Mitsubishi has a Magic Convergence,
    or Auto Convergence, or Auto Focus or something under those lines in
    the setup menu.



    Auto convergence should fix that right up for you, and will take less than a minute.

Red.yellow and green colors do not align. What is wrong? Isd it something I can fix?


If your picture has a 3D effect and you try to align with the cross hatches, then you have a convergence issue. I usually change both convergence IC's and any resistors that are open in the circuit. It requires unsoldering and soldering in the new convergence IC's. To locate the IC's, you can identify them as two side by side black chips about 3 inches by 2 inches with 18 pins each soldered to the board and on a metal heat sink. The numbers on them are identical and start as STK 392- 120 or 110. It is quite a job even for a skilled tv tech. After installing them and any resistor that is open, you will be able to align the cross hatches.
