Hi,

i just wasted 80eur on a broken TFT i can't repair.

When i got it and opened it i suspected bad things, the cable to the buttons was cut, and all the wires to the backlight CCFLs hat the plugs cut off. Also the fuse was missing and a few screws...

After i fixed the button cable and patched up some of the backlight tubes i got a picture - a very disappointing picture.

It shows clearly a spiderweb broken TFT, but the front glass is flawless and you can't see any break with the power off.

Now i'm very fed up with this, because there was a sticker on the panel front, mostly peeled off but you can see the remains. I bet my arse it did read "broken" before the seller ripped it off and sold it without telling what is wrong.

Oh well, not much to do about it i fear.

Any idea how a TFT can break "inside"? I would think this is the back glass broken, but how can this happen without the front glass beeing damaged?

I don't see how i could identify this before buying. Dead tfts are so incredibly expensive on ebay.
I really want a 18" one for the bench, the 15" one is ok for reading the odd schematic or datasheet, but recently i discovered for programming it is really not enough. And constantly moving about between the bench and the PC is quite a workout...

Oh man, that sucks! Is there anyway to contact the seller and find
out from them or is it too late with the mods you did to it?

You are also correct that in programming (as with video editing,
desktop publishing, etc. etc. etc.) you simply cannot have too big
of a monitor :-( Furthermore, the older you get the bigger the
monitor needs to be too!

I'm afraid the seller would just say "piss off it was sold defective".

IMO there is a small difference between "defective" and "has been tinkered with already".

No i don't think i'll see any of that money again. But the thing is i still don't have a second proper sceen, which is worse.
Don't understand why they are so expensive, if i get unlucky a second time i can almost buy a new one!

Until now i had been lucky with defunct TFTs, one 15" and one 18" with minor problems still working fine.

Well, sometimes you get lucky, sometimes not...

ST

Oh well problem solved.

I just bought a working 19" (pictured working and promised working) for 121eur, my limit was 122eur.
What insanity, having to pay half the price of a new one at the shops.

I still can't figure out how the back glass of the CRT could possibly break without the front beeing damaged at all.

Do you think something like a shock could do that? The break is centered about 2cm from the left edge.
I can't see any way to cause that even if i wanted to on purpose...

About the only thing I can think of that could cause
that would Maybe be thermal stress or shock. Maybe
the inside glass expanded more than the case would
allow or the case shrunk more than the glass would
allow but I HIGHLY doubt that this is the case.

It also could have been dropped. I know it's not the
same thing but I've dropped calculators before and the
screens have broke with the outside glass still
intact. (I'm 6'7" so they have a long way to fall).

In any case, its a strange part to break. Good luck
with your "new" screen.

The front is *much* thicker and stronger than the rest of the tube.

Sorry i meant to say TFT when i wrote CRT there.

So no tube.

But the back glass might be thinner as well, i dunno...

Ah, 19", you are going to love all that realestate!

I don't think it is much different to the 18" i use now, since the resolutions are the same.
But it will definitely be much better at the bench for programming.

The 18" annd 15" never worked together properly because of different resolutions. Basically i would most like to run a cloned display, but that doesn't work with different resolutions.

I think i'll make a drawer under the bench today for the keyboard and mouse. Could use your woodworking machines here, i see that getting awfully wobbly with the jigsaw, and i don't feel like clearing up all that stuff on the table saw. Hwo on earth decided a table is a good idea to put on a table saw? it is a prime surfact for cluttering up!

Sounds a lot like here, where every horizontal surface tends to accumulate
"stuff"...
