The electrical power was lost, and when the power is restored the convergence isn't adjusting as it should help!

    I have the same problem. Had a power surge and the convergence especially on the top left and lower right corners are way of.

Replaced Convergence chips, same problem


This set has pico fuses on convergence board and also on G power board, there should be 2 5 amp pico fuses on power board.

If convergence is bad exactly as before double check the power board fuses and check to see if voltage (it is marked!) is there with power board disconnected from chassis..

Sony kp-46v15 convergence problem dont know were to start on adjusting main convergence board in front were do i start there is 15 or so red green blue ajustments for horizontal and the same for vertical...


Do not mess with those, they don't just go out. they are also for skew linearity, heighth, width for vertical and horizontal adjustments. If your convergence went out need to find convergence circuit and look on the plugs for your vcc voltages going to the convergence circuit. If missing, trace back to power supply and look for an open low value resistor.

Sony kp-53xbr45 please let me know step by step how to enter convergence service thank you


Hello,

To enter into the convergence service of your sony, follow the steps below;
  1. Press "Menu" on the remote control. Use the up- or down-arrow button to move the cursor to "Setup" and then press "Return."
  2. Use the up or down arrow to move the cursor to "Convergence" and press "Return." This will bring up the convergence-adjustment screen.
  3. Press the up or down arrow to move the cursor to the line you want to adjust (either vertical or horizontal for red and blue) and press "Return."
  4. Press the up or down arrow again to move that line until it converges with the center green line and press "Return."
  5. Repeat to adjust the other lines until all three lines converge and are seen as a white cross.
  6. Press "Menu" to exit the convergence menu and return to the original screen.
You can as well follow these steps;
  1. Press the "Power" button to turn your TV on.
  2. Wait at least 30 minutes before you adjust the convergence in your television. This allows your TV ample time to warm up before you make the adjustment.
  3. Turn your TV to a cable channel or to an antenna channel with a picture that you can see. A music channel with a static shot of music notes isn't the kind of picture you need. Instead, look for a picture like what you would see on a movie, sitcom or drama.
  4. Press the "Flash Focus" button located in the front panel on your TV. You may need to open a hidden compartment on the front of your TV to access this button. The convergence will repair itself automatically after you hit this button. It may take several minutes.
Any of the two processes are detailed steps on how to enter your convergence service.

Take care

CONVERGENCE IC ADJUSTMENT


My KP-46WT510 picture is out of alignment. There is no conversion of the red, blue and green pictures on the screen. They're off by about an inch of each other.
Some tech told me that it was the power control that was bad. I can see the picture, just very blurred.
Is he right? The tv was not move at all before this started happening.

Loss of electricity due to the ice storm...


if it worked before and not after i would claim it, also sometimes if you complain to the electric company they will foot the bill on there insurance. power surge can cause all sorts of problems . just my 2 cents.
now this set is also know to have bad convergance ic
check this site out for repairing it.
http://www.techlore.com/forum/thread/18970/Sony-KP-46WT500-Convergence-Repair/

By manual convergence, if you mean electrostatic convergence, then I'm not sure this is included in the service manual. However, if you join the http://groups.yahoo.com/sonyhdtv/ group, there is a file download called ws500tweaks.doc that documents this (with the usual caveats, like don't get yourself killed, when in doubt hire a pro, etc).

Convergence problem


Sounds like bad solder connections on the convergence circuit board. Better get it looked at before the damage becomes permanent.
