SPOILER: Wasn't capacitors. Lead free solder going moldy probably was.

Although my Sony GDM-W900 24" widescreen CRT isn't [I]quite[/I] dead yet I started looking for a replacement. 24" CRTs are extremely rare these days, the couple I've seen in the last year are silly money and far away. I don't trust the seller to crate it up properly or UPS or ParcelForce etc to transport a 41kg fragile object.

I liked the look of the HP LP2475W and nearly bought one for about £75, but then I started looking for faulty monitors I thought I could fix.

Ended up...

Nomenclature fail on my part, sorry.
I noticed them when I first repaired it years ago and was setting up colour and white balance etc.
Once seen they unfortunately cant be unseen, but they're only visible against a bright white background in a dark room.

Its still alive, in fact been stable for ages. No snapping noises or need for refocusing. Im loath to disturb it to get to the service port at the back (theres at most about 9" of clearance between the back and the wall/window.

Yes, picture is top notch. Needs the odd screwdriver tweak for focus but I can put up with that, for now at least.



Looks nice, theres just something richer about the colours and blacks you get from a high-end CRT that flat panels cant quite equal.
I'll concede that [I]some[/I] of the very high-end flat panels may be getting pretty good, but since Im a Starving Hacker© they're right out of my price range. And even if they werent Im a bloody minded bugger, I love this screen and would...

Thats some really useful info there, thanks a lot!

The stairs tumble was while it was in a cardboard box with some foam peanuts inside, it originally belonged to a guy I repaired some stuff for via FreeCycle.
He had 3 that he'd bought new! They sat on a really nice custom made wooden desk.
After I admired the two he had working he offered me the broken one for parts, still in its box with ominous rattling bits inside.

I took it on the grounds that by the look of it thered be some juicy...

This interests me a lot. I have a battered GDM-W900 (not the FW900, sadly).
Got it free after it took a tumble down some stairs. Front buttons were smashed, inc the PCB behind them.
Found out that they saved IO lines by using a different resistor value for each button, all feeding an ADC.
From the values of the existing components on the PCB fragments(!) I was able to work out the progression and repair it.
Its like the FW900 just limited to 1920x1200@72, and no USB hub.
