You have several bad grounds in the convergence board. This TV will also need a new convergence IC. I believe it is a STK 393-110. It has poor grounds on its pins to the circuit board. I would suggest you replace it with a new one, it would be heart breaking to resolder the original IC and discover it is bad. It takes quite a while to pull this board out and replace. Be sure to check the 2 watt less than 10 watt resistors too. They can be bad. And I cannot tell you enough...there are also many,many bad grounds through out this convergence board. Please really examine this closely. Solder any and all ICs attached to heat sinks, power resistors, transistors, transformers etc. This TV is worth repairing. Thanks for asking and show a few hands of support!

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.

Picture in concave on all sides and blue and red are off


The shape of the picture indicates that the convergence circuit is not working properly. Generally speaking this occurs without making any sound at all. The popping you heard may have been a capacitor in the power supply. If the power line effected supplied the convergence circuit, repairing the supply should return the set to normal. If not, then the convergence ICs may be faulty. If you can solder, and are confortable working inside the set where potentially dangerous high voltages exist (even when unplugged), you may be able to repeir this yourself.

Let me know and I'll provide additional details and instructions.
