Re: convergence

IF in customer setup menu there is no convergence option then there is a possiblility that a special fuse that when blown makes think it s tube tv and then it removes convergence. I dont believe i have seen this problem on this set however. Otherwise it might be one of three different boards. there is one other possiblity that i see. the autoconvergence feature has been turn off in the service menu.

My screen looks like its 3D.

Your tv has a problem with the convergence, adjust it using the original remote go to the setting's menu then go to the convergence section. Adjust the convergence color red and blue the green color is your guide you cannot move this green color, then you should move the red and the blue in all direction left to right, up and down. If you cannot move the red and the blue far enough the convergence IC is defective it must be replace in order to align this convergence. Feel free to send feed back good day and best regards.

I had a convergence problem on my Mitsubishi WS-65711 where the red and blue was bending outward from center giving a 3D effect. I replaced the STK pack and the red and blue look good now, but now the...

green is base line center and some times is not adjustable
.Did you replace both convergance chips?
also there are 6 , 2.2 ohm res that get out of
tolarance. check them first

Convergence is off - Blue and Red are fine Green will not line up

On most units, the Green is constant and the Red and Blue are adjustable. Here are 2 links on how to manually adjust the convergence. There is a menu option using the remote control. Once there, you will find step by step procedure on how to adjust the convergence. Hope this helps answer your question. All the best!

Screen hazzy and issue with blue convergence

bad convergence would cause show to look as if it was supposed to be a 3-d movie, if a bulb was going out then people would look purple blue -green,or some other off color, so likely the green bulb is going out from the color of the people you described.

Pioneer SD-641HD5 red convergence - not chip problem!

Replace Both of your STKs if they are STK392-110s do not go back with them use STK392-180s better ICs, The 110s fall apart and do not hold up.

Red,Blue,Green Image

YOu have convergence issues. Ok first question. IN your setup menu do you have the convergence option/ if you DO not then it can be a specail fusable link. fl231 if you do. next question do the picture bow in at the middle. if you do then it possibly a convergence power supply issue. next if you go into setup convergence does the crosshairs adjust up or down left to right on both blue and red. I if so then theres is a chance that it can be a convergence adjusment or a amplifer problem AS always THIS SET CAN GENERATE LEATHAL 380 VOLTS EVEN WITH SET UPLUGED SO BE CAREFULL.

Converging green?

jaymz, you can`t move the green, the green tube is always mounted in the middle and is not adjustable from the convergence menu. red & blue should be converged one at a time on top of the green, once you have accomplished this the crosshatch grid will be white and that means your done :)

Colors out of alignment; curved lines

this sounds like a convergence issue.. one thing you are going to want is a good test dvd.. avia - guide to home theater or video essentials are two very good ones. anything that will supply you with test patterns and let you pause on them will work.

you will need to get into the service menu, using your remote press DISPLAY, 5, VOL+, POWER in quick sequence. once the screen comes up you should have green letters and numbers at the top of the screen. at this point, keys 1 and 4 change the item, keys 2 and 5 change the category, keys 3 and 6 change the value, mute enters write mode, enter executes it.

you will want a test pattern displayed that has a center point, enter the pje section of the menu and go to tphp, if you don't see a crosshair, press 6. you are going to want the convergence grid and the test pattern displayed simultaneously, so press 9 until both are on screen. it will be a crosshatch pattern overlaying your test image. use the joystick button (left or right) to roughly line the crosshatch up with your test image.

now go to tpvp and use the joystick (up and down) to finish lining things up. once you are happy with the changes, hit mute then enter to save it to memory.

this next part is from a tweaks file in the public domain that i have for this model and use any time i am working on one of these.

How to Enter the Convergence Mode
Once you're in the service menu, you need to access the convergence mode. Press the 2 or 5 key until you see PJE in white blocky letters (you should be able to get there quickly by pressing 5 once or twice). Now press 9 on the remote. You will see a bracket appear in the middle of the screen. Press 6 and cycle through the different types of patterns until you get a white grid on a black background.
Once in the convergence mode (activated by pressing 9 in the PJE section), the buttons on the remote work differently. Keys 1 and 4 move the cursor around on the grid (convergence points) in a spiraling fashion. The joystick on the remote will adjust the position of the current color at that grid point. Key 3 cycles between red, green, and blue adjustments.
You may also depress the joystick, which will allow you to move the bracket freely around the grid. Press it again and you are back to being able to adjust the position of the current color at that grid point. Handy if you are just touching up an area and don't want to spiral through all the points.
How to Converge the CRTs
It's much easier to converge the set if you can see what you're converging. Green should be the color to converge to. The geometry (straightness of the grid) of the green CRT should be good enough - If you notice that some lines are definitely out of whack, you should straighten them.
We need to disable the red and blue CRTs. Press 2 until you get to the 2150P-2 category. Cycle through the items until you get to RGBS. Change the value to 2 (Green CRT Only).
Move back to the PJE category by pressing 5. You should be back at the grid with a green bracket - If you don't see one, press 3 until you do (the bracket may have been set on red or blue, which have been turned off). Navigate around the grid, correcting any obvious errors. Once you're satisfied, turn the red CRT back on (RGBS value of 6, Red and Green CRTs on), and return to the grid. Press 3 until the crosshair is red. Now, align the red to the green, getting as close as you can. By the way, not all grid points are selectable. Keep in mind that the edges of the screen will tend to be more out of focus, and harder to get "tight". Get it as close as you can. You also may notice that some points affect the position of other, nearby points. You'll get the feel for it after a short period of time. Now, do the same for blue, making sure to turn off red (RGBS value of 3, Blue and Green CRTs on). When you're all done, turn all the CRT's back on (RGBS value of 7, All CRTs on), and look to see the results. Touch up where it is needed (if needed at all).
I found the 100 IRE Crosshatch image really showed areas that still needed convergence. I would cycle within the PJE category (pressing 6) between the convergence grid (to fix errors) and the 100 IRE Crosshatch image (to view areas with convergence problems).
Save your convergence to memory by pressing MUTE followed by ENTER.
Remember, you need to do this for each mode you use - This doesn't mean for each input. It applies to 4:3 mode, 16:9 mode, and 1080i 16:9 mode (even though 1080i is a 16:9 mode, it requires its own convergence due to the higher scan-rate). Each mode is separate, and is saved separate, however, each one does tend to affect the other slightly.
Try not to use the Flash Focus. I know it's very easy to use, and they put it right there on the front of the set, so it basically begs to get pressed. But realize that pressing Flash Focus will rely on the sensors to converge your set - It will pretty much re-do all your hard work. It may get close, but it will never be as good as a service mode convergence.
Now that your convergence is done, you should re-register your new convergence to Flash Focus (FF). Ryan says below don't use Flash Focus, and I agree. However, if you do or someone else does, it shouldn't require nearly as much touching up if the new convergence is re-registered to Flash Focus. This is simple to do. While in the PJE category, press the Flash Focus button to initiate a re-registration process to the system. If the operation fails (I've never had this happen), press 0, followed by ENTER to restore the convergence settings you last saved. You'll need to investigate why it did not work. In the PJE category, change to item ERR and it should read a value other than 000 if your attempt at re-registering FF didn't work. If our attempt at re-registering did work, it should read a value of 000. Typically, reasons why re-registering FF won't work are due to overscan being reduced too much but there are other reasons too. Regardless, while you are investigating just don't press FF and you'll be fine.
I have read numerous forums regarding re-registering flash focus. Most say only re-register flash focus in Full. This is what I did. I only watch TV in Full mode anyway, so it worked well. I have read many people having troubles with other modes if they re-register flash focus in Wide Zoom mode so I can only say, read forums and ask questions if you do use your set in other modes before you re-register your flash focus in another mode besides Full.

hope this helps you,
