Hi Sami,
Have you tried other inputs ? - Had KDL-32V4000 in today where scarts worked but nothing on DVB. Admittedly OSG worked for menu - Had a spare main board on the pile - sorted it.
All the best - Chris

Hi Sam,
Good guff from the Turnip as usual. Hope he's an organic one. Without further diagnostics I'd have to agree with him.
Chris, re your main board with no DTV/DVB (depends which side of the track you're on), usually one of 2 fuses F1 or F2 on the small tuner module that piggybacks onto the main board. Chip fuses they be, very tiny, and susceptible to being bridged out when I find one open. You may get to recycle that board again.
Very eco-friendly, if not organic.
And a bonza Christmas to you - none of this 'crimble' rot - even spellcheck doesn't want to know about it.

Hi Bruce, and well said, as ever, Though it's Sami - not me.
Have no experience of the model, never having met it, but still trying be helpful, as Quuq folks ever are.
Guess you've had a glass of Aussie festivities and are louching on the beach.
Quuq folks are asking about the next trip to Oz, but with all those snakes.
Gather Ireland was freed from snakes with gentle Jesus, but as he didn't quite call, as was rather busy.
Seems the biz, as ever - Chris.

Sorry Turnip, I hink you are wrong.
Gather Ireland was freed from snakes with gentle Jesus -- .
In fact it was St Padraig (Patrick to normal people) or Pheric (or something like that here on the island) who did the snake thing, and at the same time he visited us, and we have none either.
And whilst on missing things, whilst we have a "Foxdale", we have no foxes.
We do have Wallabies, I can confirm they taste good after correct cooking. It should not have jumped out into the front of my pal's Trannie, or maybe its grandparents should not have escaped the Wildlife Park.
Happy holiday all. -- That should upset nobody!

Hi Oldles,
Could it be that old Paddy was a charlatan, and there never have been snakes in Ireland for millennium.
Was a tad surprised to know they were wallabies there. I thought maybe you were referring to the Australian rugby union team.
While visiting the Beijing zoo once, we were advised that they kept kangaroos there, but that they were
very loathe to leave their shelter. We checked it out. Sure enough they were out of sight, but on hearing
our voices they emerged. Must have recognized the Aussie accent.
Case of nicking our wildlife and selling us their c$%p electrical goods. Bruce

Hi Les,
Guess you are right but suspect said chap acted vicariously on behalf of Gentle J as he went to spread good tidings or some-such - not yet convinced as Ireland is still trying recover from excess zeal.
Hi Bruce - gather elephants are now up for dibs due to the fall in worldwide oil prices. Gather going price is £30k per beast plus food at 50kg of something or other per day.
Would stop other chums grinding down their bits for chess pieces - well, half of 'em - Chris.
PS - Thanks for your thoughts re. those fuses, would be nice to recycle board and flog it again.

As you may have gathered, we have a Wildlife Park here, and some wallabies escaped many years ago. The area is the Ballaugh Currachs, a damp and flat area. Untill 60 or so years ago, it was "farmed", but allowed to go to pot. (No, not that sort!) Willow trees quickly invaded the whole area, which all makes good cover for the Wallabies. Apparently in the breeding season, they queue up by the fence hoping to share something. Until that same 60 or so years ago, the island was populated, infested maybe, by "little people", and stories still do the rounds. There is the church whose roof was blown off, every time it was rebuilt. Can't remember which fairy did that, but all the true manxies know.
If you like a good fairy tale, a book was written a few short years ago entitled "Fynodderee". Don'y know if downloadable, but a good read.
Back to Wallabies. I hail from Staffordshire, and it is well known that one "Sir Phillip Brocklehurst" had some wallabies which escaped and became feral on the Staffordshire Moorlands where they could be seen for many years. However, I am told they have now died out due to inbreeding.

Well, sadly for the wobblies and Irish folklore, none of this helps poor Sam with his Sony.

Hi Bruce and well said, as ever.
Perhaps there needs be a fresh column for such folks, where if they stray from the current point -
eg - Fun thoughts, plus - Historical/Hysterical remembrances, might be placed 'Somewhere' on the site for a short but justly revered period of time.
Suggest it's called 'Fynodderee' or some such, as serious mending folks won't tie it in with anything too serious, like duff Eeproms and Vestel.
Suspect 'The Isle of Man' is simply 'Phin Mc'Cool' fantasy - probably doesn't exist at all.
Reported - He chucked it there some while ago, after an argument and unknown glasses of the hard stuff.
Prosperous New Year to all Quuq Folks - Chris.

Hi all, sorry for delay. I have KDL-26u3000 with smashed screen , the main board its the same as KDL- 23b4030 main so I replaced it but no joy also I checked it from other in put and no pic. I want ask these 2 main board are the same or I made mistake.
Regards sami

Hi Sam,
You finally got a word in edgeways! Not sure if using the 26U3000 main board is conclusive. It uses a WAX2 chassis but I cannot glean any info whatsoever on the 23B4030. Do the numbers on the white stickers on each board match up exactly?
If the unit turns on OK and you have backlights, there's a chance the main board is OK. Are the symptoms exactly the same with both boards? If the tv has AV OUT, you could check to see if a monitor hooked up to AV OUT displays a picture. If not, then main board is suspect.
Guess the next step would be to check the t-con. An OK fuse doesn't exonerate it. Is it the same on both sets? If so you could try a swap. Don't forget too, the old flashlight on the screen trick.
Bon chance, Bruce

Hi Folks,
Gather WAX2 chassis has well known firmware issues. Have one myself where led error flashes don't relate to anything sensible, and the set cuts to S/by after a minute.
If new firmware sorts mine, will advise - Chris.

Thanks folks, I'll try to find T-con and check it.

Hi Sam,
It's the panel - Main board to screen - Chris
