 Posted: Tue Aug 16, 2016 9:19 pm Post subject: Sony Bravia KDL-40CX520 off colour and now ghosting |
 |
|
Model number: KDL-40CX520
Year: ~2008
This Sony Bravia started being off-colour on start-up about 4 months ago. The TV would be normal after 30 mins, which took progressively longer. Now the TV has started ghosting (parts of the image remaining for some time) and the off-colour does not go back to normal. Instead, over time, parts of the TV goes to patches of black over the first few minutes. There has been a strip up at the top, however, that has been normal throughout.
I have pulled the casing off and can't find anything obviously blown or out of place. I also updated the software and have tried leaving it unplugged for a while.
On other models, similar issues were isolated to an IC on the T-con board. The TV repair shops in my area refuse to touch it now that I've opened it - oops. Any troubleshooting advice? |

Based on your description, I'd try replacing that Tcon. You can get a used one really cheap here in the US. not sure what your market is like there.
My quick research indicates a part number of V315H3CPE6
Please confirm that before buying anything. |

Thanks for the reply.
The part number on the t con board is esp_0b_s4lv0.4
I found one supplier for this but it's out of stock.
Also, this board seems a bit different to others in that the ribbons from the LCD to the board are not detachable. See the pic below.

1) any ideas on how I could get the part?
2) how would I attach the ribbons to the board? |

I don't think that is your TCon. I think that is the panel driver... which is typically considered part of the LCD panel, and not replaceable.
I think I would probably benefit from some better pictures. |

I tore the ribbon cable at the LCD end turning it over for pics.
I suppose this one can't be revived now  |

Those are basically "ironed" on at the factory. I can't imagine anyone being successful at reattaching it in a way that would work for the long term due to the heat/cool cycles of normal use.
I'd chalk this up to a "good attempt, lesson learned". |

Yep, chalked up.
So I don't contribute so much to the ewaste out there: is there a way I can turn this into a lightbox?
Turning it on with the LCD removed doesn't work.
Also, are there any special uses for a (now) broken LCD? Other than a poor quality mirror. |

Put set all back together, have your local 'arteest'-type paint a masterpiece on the LCD screen, (signed, of course), mount it on your living room wall with appropriate lighting, brass plaque, etc. Voila. |
