I bought another lcd today without a power supply; another with the four pins in something like a five sixteenths square. This is an "Ever Yoke" model tl700a; the other is an hp pavilion 170. Can anyone tell me the voltages on the pins, by any chance? I know the Ever Yoke is 12v but not on which pins.

Re: Lcd power
Look at the PCB.
+12v will be the pins that aren't ground.

Hey, thanks for that, PCBONEZ. I've worried that mystery for awhile.Comment

Re: Lcd power
Rigged a 12v power supply and the Ever Yoke works fine. The hp however starts up with a very yellow screen, cuts on and off randomly until desktop, at which point it shuts down completely. Do I have a problem here of the wrong voltage maybe_ it's not marked_ or does this sound like a pcb problem? I haven't checked caps or anything yet.Comment

Re: Lcd power
Check your power is right first.
Look up replacement power bricks for the HP.
Some of the ads will state volts and amps.Mann-Made Global Warming.

Looked for that thing for I guess a year or more now; have yet to find one_or any kind of documentation on this bird. You'd think they only made the one unit.Comment

Re: Lcd power
The HP bird or the Yoke bird?
I was talking about finding the voltage for the HP.

Re: Lcd power
Both birds actually. I've had the hp quite awhile without being able to find anything on it; the Ever Yoke I just bought but couldn't find anything on it either. Add to these the Apple Cinema I have and it's getting to be a flock.
Anyway the Ever Yoke is good now; I'll just use it for a bench unit.Comment

Re: Lcd power
HP Pavilion 170 is a system not a monitor.
Look up replacement power bricks for the monitor's model number.

Re: Lcd power
I'm cringing in shame, PCBONEZ. Took another look at the hp for another number and suddenly realized I'd read the number wrong to begin with. It's f70, not 170, and ebay has the supplies.
But_since it calls for 12v like my jury-rigged supply I guess that means the unit it's self has a problem. I'm ordering one anyway since it will presumably work on the Ever Yoke. My rig is only 3.3 amps rather than 4 but I doubt that would account for the problem.
Any ideas on where to start looking for the bug?Comment
