[chrissie jones]

Afternoon guys...just had one off thease set in today..this is my first sharp to look at...when switch on,green light flashes few times and back life comes up for one or two seconds then goes back to red flashing standby light...anyone worked  on this set before.....it's not a vestal

Hi,
Had this fault on a 32", not sure if the same applies to the 46",
but it might be worth a check.
'The voltage across the main smoothing capacitor should be about 350V during
Standby and increases to 395V during power on and normal operation,
if it does not change or is low, replace R7832, R7833, and R7834 (511K ¼ watt 1%),
located underneath the main smoother capacitor.
They change value (go low) e.g. 496k, 455k etc.'
Try CHS, Part No: MFH510K (510K .6W) for standard, wire ended replacements.

Regards

Hi Chrissie, 2 seconds of backlight then continuous slow flashing of red LED (error code 1) is a backlight error. You should be able to make it operational by accessing the service mode....should be heaps on quuq about it.....and resetting the lamp error count to zero. 5 strikes and you're out on these. You'll still have to locate the reason for the failure or it'll come back to haunt you. Mostly CCFL failure on these.

Yes..you where rite oz..all back life ccfl tubes all blackend on ends....thanks for the reply..

[downunder]

Chrissie, backlight is what you mean. They're usually expensive, unless you can pull some from another wrecked set, but precise length and diameter may present challenges. Nice feedback.
Chris la Turnip will be impressed.

Hi Bruce,

Impressed as ever,

Have a whole heap of tubes from screen smashes where length and diameter are carefully noted.

Admit have had sharp tube problems and used anything handy, modifying the end bits to suit.

Made the pound - Chris le Turnip - well, i'm sorta' masculine, still.

Guess one can never trust an Aussie as to gender, for some reason - Chris

[downunder]

Oops, sorry for the faux pas, le Turnip, didn't intend to cast aspersions on your gender, but in this neck of the woods French lingo is a worthless commodity.
One of the aboriginal languages, Pitjantjatjara, is more useful. At least I speak English.

I,ve read of your exploits with backlight adaptation. A tad hair-raising I admit, but as long as it brings in the needy pound (perhaps for the needy turnip).

[Turnip]

Hi Bruce,

You have me there, but suggest you don't ignore French - totally.

Anglophiles suggest the french have something, like 'Le Upper Cut' which is truly 'gallic' in some respects.

Wikky suggests Garlic, which I prefer.

As to backlight tubes, I tend to fit those that I have, maybe have to twiddle the ends a bit - but makes the needy pound where genuine replacements would be daft.

Kai-ora - Chris.

I remember years ago twiddling pots.....Nah, we'll Spooner out of this one.

 Hi, Turnip & downunder

you're really right a little bit of fun helps as our bussines drops.Good luck!

[Turnip]

Hi Mike,

Feel fun is the thing, we mend tellies seriously but can't help giggling at some entries, where folks don't quite know the make or model, but just want a free-mend.

Well, it's a free site, so some crap is us.

There are other sites where professionals chew the biz.

Costs a bit, and some professionable folks don't actually mend anything, just chew on  - Chris.

Hi Bruce,

Guess you'll have to do a Spooner on Quuq,

Our Prince Charles has just suggested that the bare chested Putin might be suspect, or even a dork.

Had some suspicions - Chris.

Bit sorry can't do whimsy on other entries, but only For a Quuq hero.

Guess Quuq heroes were formerly checked for possible future invective, as few can spell, and those who use spellcheck seem still to have problems with English, Giving us lesser folks a chance for a smile.

Suspect some antipodean stuff might be the biz- Enjoyed 'Walkabout', but could have been the gal, as she was well nifty at the time.

Must admit, never had tubes more than 24 inch with this problem unless Sharp with that ghastly inverter edge connector biz.

[OldLes]

I started a thread back in December on a 42" Sharp. That had problems with those edge connectors, but even after testing all CCFLs, including some replacements, it would light up for a brief period then shut down.
I was unable to reset the lamp failure counter, so in the end I returned it to the amenity site just before they started charging. It was a beautiful set, just screaming to be fixed, but it had me beat.

 Hi,Chris,
 
I must confess I'm delighted by this mixture of professionalism and fun.Thanks.

[downunder]

Hi Turnip,

I also enjoyed that film, albeit a distant memory. Probably was the good-looking Jenny Agutter.
I remember an absence of much script in the movie.....Twould be right at home on the quuq forum.
