Call for help...
I've just acquired an HP 1702 TFT in unknown working condition. I connected
it up, and (to my mild surprise) it worked fine. I've had it connected to my
PC for a couple of days without any problems. This morning, I moved it over
and connected it to my second PC, and since then it has stopped working. It
doesn't turn on. The same happens when I move it back to where it was in the
first place. It's not completely dead, but nearly: by this I mean that when
first connecting it to the mains, the status light goes briefly orange, then
green, then shows the correct display for half a second, then completely
turns off. Then it's completely dead, unless I unplug it, wait a few
minutes, and plug it back in, at which point it will usually go through the
orange-green-off cycle again (plugging it back in immediately normally does
nothing). I've put up a really bad video (admittedly not very helpful) of
what happens when I plug it in: http://users.panafonet.gr/annalef/screen.avi
Any experts able to diagnose a specific problem? Any advice on what to do? A
friend of mine said he may be able to repair it, but would need the service
manual/circuit diagrams for the screen. Can this be found anywhere? Would it
be economically feasible (compared to the price of a newer and better
display) to give this to HP for repair?
Any advice appreciated!
Thanks,
Gregory
