Question about Philips Magnavox 51MP392H Rear Projection Television

2 Answers

Convergence problem We have blue wave at top and bottom of screen, when we try to manual converge on multipoint blue screen the crosshairs just won't move, they shake but that's it. We live an hour away from a repair shop, would like to fix myself if possible. tv is too big to haul very far. And I don't want to spend 2 to 300 dollars on it either.

Hello nursecmp,

You have a convergence amplifier problem. Now you have two choices: 1) fix it yourself or 2) Get it fix by a qualified TV repair person. Granted if you choose the latter, you will spend about $200-$500 depending on the shop. So as you stated you would want to do this yourself. OK, I will not get into the problems with this, rather I'll give you the basic procedure and the you can search fixya for a more in depth solution (I'll show you how to do this after the basic instruction on how to replace the Convergence Amplifiers (I rarely give these instructions) Here goes:

1) Get the schematic/service manual for this TV (You will need it because it contains the part numbers and component values you will need for replacement)

2) On the schematic/service manual locate the convergence amplifiers (STK392-110, 120, 150) and the biasing resistors (Write the resistor values down from the schematic)

3) Unplug the TV and remove the rear cover to expose the electronic circuitry.

4) Using the schematic/service manual find the physical location of the two convergence amplifiers (Usually attached to a big metal silver in color heat sink) (Basically it will look like two big black six sided flat modules with a lot of pins on the bottom (18-22 to be exact)).

5) After finding the heat sink and amplifiers remove the screws or the tension bar holding the amplifiers in place.

6) Using a soldering iron and a de-soldering device (either a de-soldering pump or de-soldering wick) remove the solder from the pins of the amplifiers and biasing resistors that protrude from the solder side of the circuit board. (Take into mind that you may have to remove the board in order to do this, use the instructions in the schematic/service manual to do this, and make sure you mark everything you remove to make sure you have a guide as to how to put it back)

7) After removing the solder from the pins off the amplifiers and the biasing resistors, remove the resistors making a list of the value, part number, and location on the board (all of this should be in the schematic/service manual). Then remove the two convergence amplifier modules taking care so as not to damage the circuit board. NOTE: The heat sink compound (the white goopy stuff) may have hardened and caused the module to stick to the heat sink, you will have to gently pry the module away from the heat sink, I have used a light application of isopropyl alcohol to dissolve the heat sink paste.

8) Once the modules are loose from the heat sink, you can gradually remove them from the circuit board.

9) Clean the heat sink off by using the alcohol and a heavy paper towel (remove all of the heat sink paste, and yes this is messy)

At this point you have removed the two convergence amplifier modules and the biasing resistors and cleaned the heat sink.

Now you will have to use your schematic/service manual to find the part locations, values and numbers you will need to replace the old parts I suggest replacing the biasing resistors first.

1) Sort out the resistors you will need and as stated in the schematic/service manual and replace them according to the schematic/service manual locations and part numbers.

2) Solder the components (resistors) in place making sure not to short out anything in the process.

3) Apply heat sink paste to the metal side of the modules one at a time and the put the modules into the circuit board lining up the screw holes of the modules with the screw holes in the heat sink, use the removed screws or tension bar to hold the modules down once in place in the circuit board and on the heat sink.

4) Solder the pins of both amplifier modules to the circuit board, taking care not to short out anything.

5) Reinstall the board to the TV, reconnect all cables removed (DOUBLE CHECK EVERYTHING)


If all went well the convergence amps should be working, and you will need to realign the convergence of your TV, I suggest using the AUTO Convergence feature of your TV (Use the instructions in the schematic/service manual).

All should be good now.

Now these instructions are generic in nature but can be use for a number of Models of Projection TVs.

Is there a code number that needs to be entered to bring the convergence pattern or menu on screen.


From a user standpoint you would follow these steps to bring up your Convergence menu:

1) Press your MENU button.

2) Press the Right Cursor Button to enter the Picture menu.

3) Press the Down Cursor Button until you highlight the MANUAL CONVERGENCE choice on the menu.

4) You will then see the following choices on the right hand side of the menu: Convergence Red, Convergence Blue, Multipoint Red, Multi Blue, Save Multipoint.

5) Once you choose either the Red or Blue choices you will get a crosshair in the middle of your screen. You will then use either your Up, Down, Left, or Right Cursor buttons to get the two images to line up correctly. If you still have multi images on your screen in either Red or Blue you would then have to adjust the Multipoint choice for that color.

Need code to enter on remote to engage multipoint convergence adjustments.Need save proceedure after adjustments are made & exit proceedure for RCA Projection TV Model # HD52W59, ITC 222A


Hello,

To get the code to enter on your remote to engage multipoint convergence adjustments, you need to contact the rca customer care for that, you get them your model number and they will get your code for you.

To process and save the adjustment made, follow the steps below;
  1. Look through your manual. Your manual will always give you the most specific directions for your particular model. Look for an "adjusting convergence" or "set manual convergence" section.
  2. Enter the menu on your TV. Use the remote control and bring up the menu.
  3. Choose "Convergence." This may be under "Picture Settings," "Function" or "Advanced Options."
  4. Select a color. You will have red, green and blue to choose from. Do each one, starting with red.
  5. Press "Enter." A crosshair pattern will appear on your screen.
  6. Adjust vertically. If there is a horizontal red line visible, press the up or down arrow keys (or channel up or down) to adjust the convergence until the line is superimposed on the horizontal-center line of the white crosshair.
  7. Adjust horizontally. If there is a vertical red line visible, press left or right (or volume up or down) to adjust horizontally. Do this until the line is superimposed on the vertical line of the white crosshair.
  8. Save settings. It is important to save your settings when you are done, instead of simply exiting the menu.
  9. Repeat these steps for all colors.
Take care

I have a Philips 51PW9303 Rear Projection TV that had blue shadows around the sides of the screen and now has a green and red bowed line at bottom. Does I need a convergence board to solve this?


If the following doesn't work the tubes could be at the end of life:
Adjusting convergence:
Note: For best results, the Projection TV needs to be turned on for 15 minutes or longer before adjusting the picture tubes (convergence).

To adjust the convergence of the picture tubes:
  1. Press the 'MENU/SELECT' button on the remote.
  2. Press CURSOR RIGHT to enter the PICTURE menu.
  3. Use CURSOR DOWN and RIGHT to select and enter MANUAL CONVERGE.
  4. Press CURSOR RIGHT to select CONVERGE RED or press CURSOR RIGHT and DOWN to select CONVERGE BLUE.
  5. A crosshair will be shown on the screen. If there is any red or blue fringe around the crosshair, use CURSOR RIGHT, LEFT, UP, DOWN to try and merge the fringe colors with the crosshair.
  6. Press the 'MENU/SELECT' button to return to MANUAL CONVERGE menu.
  7. Press the 'EXIT' button to exit the menu.
If you are satisfied with the convergence you may stop now. Otherwise, you can continue and adjust the convergence more using mult ipoint convergence.
To Adjust multipoint convergence:
  1. Press the 'MENU/SELECT' button on the remote.
  2. Use CURSOR RIGHT to enter the PICTURE menu.
  3. Use CURSOR DOWN and RIGHT on the cursor ring to select and enter MANUAL CONVERGE.
  4. Press CURSOR RIGHT and DOWN on the cursor ring to select MULTIPOINT RED or MULTIPOINT BLUE.
  5. A grid of crosshairs will appear on the screen. If there is any red or blue fringe around any of them, press CURSOR RIGHT to enter NAVIGATE mode.
  6. Use CURSOR RIGHT, LEFT, UP, and DOWN to move to a crosshair that has a color outline.
  7. Press the 'EXIT' button to enter ADJUST mode.
  8. Use CURSOR RIGHT, LEFT, UP, and DOWN to merge the color with the crosshair.
  9. Press the 'STATUS/EXIT' button to return to NAVIGATE mode. Repeat as necessary.
  10. Press the 'MENU' button to return to the MANUAL CONVERGE menu.
  11. Press CURSOR DOWN until SAVE MULTIPOINT is selected.
  12. Press CURSOR RIGHT to save the multipoint settings.
  13. Press the 'EXIT' button to exit the menu.

I have a blue/green wave on bottom and on top of my tv tried to reset convergence, still the same, crosshairs won't line up.


Your symptoms sounds like a damaged convergence IC.

There are two and sometimes three very large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink.

Most of the time you can just correct the convergence through the television menu. All that needs to be done is line up the blue and red to the green. If the colors do not move then there may be faulty components in the convergence circuit.

I hope this information allows you to resolve this issue.

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 email and they will put one together for you. Their kits includes photo instruction guides, original Sanyo STK chips, convergence resistors, pico fuses, etc.
