SONY BRAVIA pixel question
I have a 40" sony bravia LCD , and every so often, only once a night, one or two pixels in a line go WHITE. I have only noticed it whilst watching SKY though a SCART input, and turning the sky box off then back on cures the problem. I have not noticed it whilst playing any of my consoles connected to the TV via HDMI or RGB. Also it looks like this only happens when the TV has been on for a while. Has anyone got any suggestions, what the problem could be

Are these toward the top left of the screen? Could they be the WSS line 23 widescreen flags?

We had a problem with a missing pixel on our Sony TV that only appeared occasionally. After a lot of hair pulling and research we found that the pixel only disappered when we were watching a recording that had the child lock on the programme - when we removed the lock the pixel appeared again. Could this be the answer to your problem?

Not sure if it's related, but on my 32" Bravia - when I play DVD's that are 16:9 format, I've noticed that I often get some - what look like black 'sparklies' at the top of the picture. Only ever happens on 16:9 and not 2:35:1
I'm yet to investigate if it's the DVD player or the TV. Just wondered if anyone's had anything similar aswell? |

LCDMAN, you may have a point they are towards the top left, but not exactly in the corner and not always in the same position. but it looks as though there are 3 or 4 pixels joined. And as i say flicking the SKYBOX of and on makes them disappear..............My main concern is that its the dreaded dead pixel scenario. We have had the TV for well over 2 months now,

![]() Sony are currently working on a software update to cure it, and (last I heard) it was expected from Japan 'imminently', however, they then have to test it to make sure it cures the problem, we've actually supplied them a set that does it, along with photos of the problem. If you ring the Sony helpline number, they know all about it. But it is VERY intermittent, I've never actually seen it happen, only seen the photos. |

There is a known fault on a range of Sony models, it looks like a sideways '!' near the top of the screen, about quarter of the way in from the RHS (as you look at it). It only affects SCART, RF and HDMI are OK, and it's VERY intermittent - if you flick from RGB to PAL (or the other way) the fault disappears again.

Sony via email support have "never heard of this problem before" and directed me to my local Sony repair centre who also have never come across this problem either.. An AV Forum I frequent has a number of people with V3000's experiencing this problem and also at least one member with a W3000 and another with a D3500 also with this fault. Does anyone know if it's ONLY scart that is affected? Could I use a Scart > component lead and get around the problem? has anyone tried this? One guy has had his set in his local service centre 3 weeks now and they cant say when he's getting his TV back which I find wholly unacceptable. thanks... Ray |

Tell your local service agent to RING Sony technical, they know all about it, all they will be doing is checking Assist (Sony computerised service system), it's NOT on Assist, and won't be until a cure has been released, and it will take a few months before it appears then.

Hi Nigel
thanks for the info, please keep us updated on anything you hear it is much appreciated, you seem to be the only guy in the know i've found so far. It occurs on my TV only when it's been on a good 4+ hours. I've never seen it yet within an hour or so of the tv being on. There is seemingly no aparent cause of the problem, IE: not changing channel, happens regardless of bright or dark video viewing, regardless of cheap or expensive RGB scart leads. Mine is exhibiting the problem quite often now, approx 4 times this week already since Sunday evening. This is what i mean about Scart > component lead.. or am I barking up the wrong tree here and have the wrong cable? http://www.tvcables.co.uk/cgi-bin/tv...ml?id=Tb5ZrmJt or http://beststuff.co.uk/specialist_rgb_leads.htm I'm after knowing if taking an RGB SCART output from my SKY+ can be input to the KDL-40V3000 component (not composit) connections and if that will eliminate the white line problem. has anyone tried it? Would there be any degradation in video quality over RGB SCART? Many thanks.. Ray |

If I get chance, I'll try and find out what's happening tomorrow - so far our stock set has disappeared to Sony, it's not been replaced, we've not been paid for it, and we haven't heard back from them at all (apart from the last time I rang and asked). |

Hi Nigel Quote:
It wouldn't work, there are no Component outputs on almost all SCART sockets, and certainly not on any Sky box SCART - the lead (which is ludicrously expensive) is for the extremely rare sets that might provide Component over SCART (which is really a complete waste of time anyway).
![]() I'd love to go HD but currently cant spare the funds for SKY-HD. Will perservere with the RGB SCART and hopefully Sony will come up with a fix soon. Quote:

that would be excellent thank you. Ray |

Also, just remembered. Sometimes on the E4 logo the TV goes screwey with dancing cubes and weird blocks on the edge of the blue logo on white background as if the set cant make up it's mind how the channel should be decoded. have you had this reported before at all? No biggie as the logo is off in seconds and the set returns to normal, just looks weird.

I will try get a picture. It's no big deal really though just looks weird. could be related to the white line problem, the only person i've seen mention it so far is another guy who is experiencing the white line fault..

In the meantime, any service dealer requiring it can ask Sony technical and it can be emailed to them - mine came with the email they sent me. BTW, our TV they had is on it's way back via UPS. |

In good company..
I've been having this stuck pixel row issue with my V3000 practically since I got it, and confirm that it is definitely a problem and I can supply a picture of it happening!
If it can be solved with a software update could someone please post here, who to contact, number etc. to get this arranged. I mostly watch a Topfield PVR on AV2 and it happens at unpredictable times on both the top and bottom of the screen. Regards S |

Can I get this software update to do myself? Or have I got to get Mr Sony over to do it for me?
If anyone could post the number here to arrange a visit, I would be grateful. |
