 Posted: Mon Feb 11, 2008 8:00 pm Post subject: Sony 51" projection KP-51WS500, Convergence card bad? |
 |
|
We picked up this TV recently and this is the picture we have. I someone thought it might be the convergence module (D card?) that needs to be replaced. The picture is little fuzzy with all the 3 colors visible but look a lot better in the center, the further out from center of the picture the worse the picture is. Can anyone help with what the problem might be from the pictures?

Start with IC8001 and IC8002 STK392-560's.
PS8002/3/4/5/6 are your pico fuses check them also.

Is there a card that is also responsible for the convergence? Not sure what else to do with the IC's but replace them. |

| The 'card' is a DCU/digital convergence unit. It stores the data. 99% of the time it's the IC's. |

Also found that in Maintenance Mode, auto focus throws the error, "Error G, lo level SO". That should be the top light sensor, so would that also mean the guns are out of alignment? |

The guns are out of alignment because of the bad ic/ic's and open pico fuses. You lost you convergence reference. Sensor error because it can't realign the convergence until it's fixed. |

Thank you!! I will replace them and see what I can get. |

| I modified the post about the pico fuses. Their 3.75 amp so use 4 amps. |
