I know that chipset is Realtek. I know this only because I've seen that funky crab logo before, on modem cards. It's a memorable logo in comparison to other logos on chips, imo.

To unscrew those seal screws I used to push onto the screwdriver to force it open or use a steel drill to file the screw head off, maybe that is helpful?

I usually just tighten the screw until what it is threaded into breaks, or until the bit it is clamping snaps from the extra force.

i used to do this way too.

superglue/hotglue/silicone/liquid nails and its all back together neat and tidy.

GET THE PHASER !!!
Those squirt hot wax instead of the classical powdered toner !
The 'ink' is a block of colored wax that is melted and squirted like an inkjet...

3d printer anyone ? Might be a killer extruder !

That usb hub is real quality. There's even common mode chokes on the datalines !

Yep, it's easy to spot so you can stay away from it!

The UPS probably just needs a battery. Hook a PSU up to it and see if it comes on.

Those cam head screws will usually unscrew if you use a sharp screwdriver with plenty of pressure, they just bite into the screw head enough to undo the screw if that does not work hold the screwdriver down hard with some torque to undo the screw and lightly tap the screwdriver handle with a hammer, I have never had one that did not come undone.

[David_AVD]

That UPS battery looks to be a standard 12V 7.2Ah type.  When they fail you can sometimes hear them rattle when you shake them.

Like Monkeh says, hook up your bench supply and give it a whirl.  Do it without mains so the UPS doesn't try to charge your power supply of course.

If it is one of the solid ink (wax) printers it's certainly worth a quick look. Totally unlike a normal laser and the output on the few prints I've seen is beautiful - slightly raised, slight shine, it really stand out.

I had a failed LCD monitor I took apart last year. I didn't use any of the electronics but I did keep some of the mechanicals. It had a very nice large piece of plexiglass, and several nice thin sheets of translucent and pure white plastic I can use for modelling.

Removing the security screws may be an application for a left handed drill bit. The drill will cut into the head and since it's a left handed bit, the drilling torque will act to back the screw out. Even if the screw does not back out, if the head is drilled off, you can separate the enclosure halves and remove the screw body with a pair of locking pliers.

It's jut a crappy mono laser Phaser.

Hi Dave,

I see that dead monitor is a LED backlight unit.

Any chance of giving us a look at the led back lighting matrix layout.

You might have a lifetime supply of rgb leds there

Many thanks

I have removed those security screws before by dremeling a slot into the head and using a flathead to remove it. Only works if you can get the dremel in there though.

[DavidDLC]

I do something similar, but instead a dremel I use my micro mill machine. It works very good as well.

David.

Why would they use RGB LEDs? Yeah, the light spectrum is different, and possibly better suited for blocking with an LCD because of the narrow wavelength, but I don't think they'd bother. At least not on a cheapo panel like this.

[FrankT]

KVMs often use custom cables.  Did you keep them?

[maddhatter]

With the UPS - try a new battery.

Typically (maybe not on this particular model, but on many others) there is battery failed protection which prevents mains input unless the battery is good.

[SeanB]

Got the Phaser 340, works, but the running costs are astronomical...... But black is free, though you will have to spend at least $100 per turn on, and $500 per month if you keep it on.

Was nice to strip it's cousin, as it had been switched off with a paper jam.............. Scratch one printer.

My grandmother has a finlux led lcd tv that has a array of white LED's (blue led with yellow fluorescent) at the top and bottom edge of the screen, the weird construction allowed to see some of the LED's from the back panel ventilation grid. I would love to see the rgb version of backlighting too.

A common drill defeats them, too.

You might be able to use the driver board to replace one in another monitor that has a bad (as in buggy) driver board and a LCD with the same native resolution. (Assuming, of course, the driver board you salvaged isn't also buggy!) I have a 1080p Viore monitor that has a great panel but a really horrible driver board (HDMI is cut off on all 4 sides and it takes a really long time to boot up). The only solutions I have found cost at least a significant percentage of just buying a new monitor.

Or you can just hook up the LVDS outputs to a FPGA board and get a video input on your FPGA without having to deal with all of the HDCP, EDID, and whatnot.

[peter.mitchell]

or you could just screw them up until there is no thread left in the plastic then pull the cover off? when you put it back together you're going to use different screws (that have a normal head), so you just get some with a bigger thread so they bite.

[Unixon]

Dave, make a T-shirt with the image from that broken monitor. It is enough artistic for that. 

[Ferroto]

You should throw some cheap used video cards into the video editing PC and run 6 monitors. Any serious video editor needs atleast 6 monitors the more the better.

Trust me once you go multi-monitor you don't go back

[sullyRD]

I cannot believe you got a 8 port KVM switch as well what a score, i hope you picked up the cables as well because they always sell on Ebay easy enough. I use a Belkin OmniView Matrix 2x8 (16) model F1D208-OSD and it is rock solid reliable, I always have at least  :-+5 computers hooked upto mine with a spare cable for connection to the computer I'm repairing. 

[tom66]

Dave, if you still have the cables going to the LED panel (one thin one and one white ribbon one) I am in need of these to fix another monitor I picked up for scrap. Any idea how much you'd want for them, including postage to the UK?

[newtond]

I had issues with this one way screws before.
I solved with this little tool:
