Toshiba 57H82 convergence problems. TouchFocus


See my solution <http://www.fixya.com/support/t2795690-convergence_off_blue_line_only_vertical>.
You need to get to the service menu--it's been 4 years so go to AVSforum.com to turn off the different guns and get the better pattern.
At your risk: To get into Service mode:
1. Turn your TV on. 2. For X81 or earlier series: Press MUTE on your remote and release. 2. For H80/H81/HX81 series: Press MUTE on your remote and release two times ("Mute" on-screen) 3. Press down MUTE on your remote again and hold. While holding, press the MENU button on your TV set's front panel. 4. Release both buttons. 5. An "S" should appear on your screen. Press MENU again on your TV. 6. Now you're in service mode. Channel Up/Dn - Scrolls through Parameters and Volume Up/Dn - Changes Parameter Value
To get into convergence mode:
Get into Service mode, then Hit '7' to bring up the convergence grid. Buttons 100, 0, and ENT control which gun you want to turn off (if you want to align the red to the green without seeing the blue gun and other variations). 2=up, 8=down, 4=left, 6=right, 3=change gun to converge, 5=converge that point. To exit convergence mode you press 7 once and your screen should look like it's imploding then return to normal and then you press 7 to get back into regular service mode.
I have more info found on the board. -Ken

You need to check for bad soldering in your tv .

Also bad capacitor can cause this problem ,

How old is your tv ?

Samsung HC-P4252W convergence problem


You need to change the convergence ICs. This is an inexpensive repair if you do the repair yourself. The ICs are located on the big heatsink they should Be STK392-110 or 120 or else they could be STK 392-010 or 020 . But what ever STK number you have you will need to replace both. Here is a link where you can get replacement ICs and they include step by step installation instructions with the new ICs. Here is their link.

More than likely your akai has defective stk392-040 Convergence chips . it also may have open resistors generally 3.9 ohm flame proff. this board is attached to the top left looking from the back of the set it is screwed on by 1 screw black in the center . after installation this will probably half to be converged dinamically. which means you will half to get to the grid this is done by using the remote press mute 183 quicly to enter numbers on thew remote 2 to adjust red 4 to adjust blue horizonta 6 to adjustred vertical and 8 to adjust red vertical using center button to go up and down

Service mode for convergence


You enter the service menu by using the remote. Press DISPLAY, 5, VOL+, POWER in rapid succession. Once the screen appears, you should notice green letters and numbers at the top of the screen. Your remote acts as a navigation tool to allow you to select and change values. Keys 1 and 4 change the Item, keys 2 and 5 change the Category, and keys 3 and 6 change the Value. MUTE enters the write function, and ENTER executes it. Power exits the service menu. Keep in mind that while in the convergence mode, the keys have different functions, which we'll get to in due time. The service manual will also have this information.

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.
Controls
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,
trin

Convergence


Replaced convergance power packs (2) stk392-110 check all 2watt resistor the packs, to enter the convergance alinment mode on the set. Using the remote control press and release the sleep timer button when sleep timer displays timer equals zero immediately press the display and V. status buttons at the same time.  If done quickly enough the service menu will appear once entered the careful not to does disturb or change any other settings press the number seven to enter the convergence alignment mode a full crosshair pattern will appear in this alignment mode you can adjust the blue and the red to line them on the green using the select and the number pad you can move to the next crosshair to align the boot to the green and then the red to the green when done pressing the muting button on the remote control will save your changes will take a little while to figure this out as you work with.  If you make an unwanted error pressing exit without hitting the muting button will restore your convergence to its previous  setting.  If you're green is off after entering the service mode press the number six on your remote control in this setting will be able to adjust the green only once that is done us the muting button.  Then enter button seven if need be to adjust the blue and the red.  Remember no changes have been stored until the muting button is pushed open this helps.
