Compaq TFT 5000?

[Ehuwiko]

I see a couple of these on eBay. I've read that the TFT500 was DIY-able, but the ribbon cables are short. Is the TFT-5000 similar(or the same)? Anyone know the specs, I can't find anything other than the fact it's active matrix and 1024*768. Also, no power, do most LCD monitors take standard adapter voltages/heads? If the specs are decent I might get one, there's three for $85 a piece, working, with no defects. I'd be willing to take a gamble, If it didn't work out I could always use it for it's intended purpose.

Hi there!

The old Compaq TFT monitors are a bit tricky. I bought an old Compaq TFT 450 which is basically the same as the TFT 5000 except for the possibility to use the screen vertically. They have this special Compaq-only AC Adapter which costs around $120. It uses AC220/110 for input and puts out 12V and 5V at 2A plus the plug is PS/2 type. Two pins of the PS/2 connector are 12V, two are 5V and the other two are GND.

So either you have to buy a new AC Adapter for around 120 bucks or you have to go and build one from two other ac adapters one with 12V and one with 5V, put them together with a PS/2 connector and there you go.

Not easy, but doable.

Good luck!

I might be disassembling one of these LCD panels myself. Is there any difficulty with ribbon cables or the pcba's orientation with respect to the LCD?

Thanks

Hi There drwenkman,


You wouldn't happen to know which pins are 12 & 5 vollts

I am going to try I may get a tft450 / 5000 this weekend but no psu

If this is the coonnector

which would be 5V/12V/Gnd

Thanks for you help

I've got a FP500 where the psu broke down a few months ago.

I just got a 7810 (10 volt 2 Ah regulator) and hooked it up with an old 20 Volt printer supply and it workes great actually better then before.

Hi there!

the pins of the male connector should be like this:

______GND_GND
____5V____I____12V
____5V_________12V


Enjoy your TFT 450/5000!

Hi,

I'm quite new to electronics, but I got also one of those TFT450 without the powersupply.

What I don't know: Is this the pin layout, that one sees, when one looks at the male connector (as one would do it normally), or the way it should be soldered to the connector (as if one would look from inside the cable to the connector)?

Can someone help me with this?

the compaq TFT5000 will work, but you will have to extend 1 of the 3 FFC's. ( the smaller one)

i can get you a pic if you would like.

as for the power supply. i have a TFT500, it uses a normal barrel type plug. it takes 12V 3amp input. it also does have this PS2 looking type connector but i believe this to be a service port ( correct me if i'm wrong.)
the power input i'm using in on the opposit side.
here's a pic.

Hi DR_WEH,

The 450 has only the VGA-connector and the female PS/2 one.

Check postings #2 and #6 for some other details.

For the power supply I am considering to use an old AT-psu or the psu from an external SCSI box. I was told, that it is a bad idea to connect two power supploies (as suggested in posting #2).

The 450 has two fuses quite near the PS/2 connector, which lets the power connector thing sound more likely.
But it's really hard to guess, what belongs where.

Yeah, if needed, I can also take a picture of that (it's currently open anyway).

Hi there.

Was wondering if anyone had any luck with those tft450 pinouts?
