HP Pavilion F1703 TFT Monitor Blackout - factory reset
by andyoddjob - 6/29/08 1:17 AM In reply to: HP Pavilion F1703 TFT Monitor Blackout by germansalI was given a faulty f1703 by someone as it was out of warranty, had no help from HP and bought another brand replacement.
Same problem everyone else seems to be having. Press the on button, came on for a second or so and then went blank. Press button again, turn on again and the same happened.
I managed through trying time and again after pressing on to quickly press menu, then go down to Factory settings, press select, go down to Yes and press select again. This reset to the Factory settings and it seems to be working okay. Been like this now for about a week. I don't know how long it will last - if it goes again will try re-soldering. Guess I won't be buying HP products as this was a part of a very expensive system.
I don't know if this will help anyone else but if anyone tries and gets a monitor back up and running please let me know.
All the best...
Same problem with f1903 model
by Perky Pants - 11/7/08 5:35 AM In reply to: HP Pavilion F1703 TFT Monitor Blackout by germansalHi, a few months ago my f1903 had exactly the same symptoms as displayed for the f1703, after almost two years of service, not very heavy usage. Can see the desktop very faintly, and the backlight goes out in a couple seconds after doing the off/on thing.
I only just now found this thread, and since I've been wanting to get a new monitor (I'm on my backup CRT) figured I should try the fixes first. Tried all the screen resolutions, power cord things, but no dice. So I opened it up and inspected the capaciters, none are leaking or burst. I found one suspect solder spot and heated/added solder, but no dice. Then I went kind of crazy and soldered a lot of connections but nothing. (well, I did get better at soldering!)
Part of my problem is that I don't know what inverters or coils or even an inverter board is. My f1903 has three boards instead of the f1703's two so that compounds the problem. One at far left as looked at from back is brown, with aluminum heatsinks, the AC adapter that the cord plugs into, and one toroidal copper-bound thingie and one square box-like thingie that has two sideways cylinders in it wrapped in copper (plus of course a lot of other stuff). Then in the middle there's the green board with the processing chip, it connects to the video adapters, and has one connection to the screen. Then there's a light beige board with four plug-in connectors to the screen which I think (?) is the inverter board. It has two horizontal cylinder thingies wrapped in copper, and two others that look almost the same. And two larger rectangular box-like things where the copper is wrapped vertically, and the rest of it is black, looks like a long box and has a lot more leads out of it. The two larger boards connect to each other with a cord going past the green board, so I don't know if they act as a single "inverter board" or "power supply" or what.
I'm about given up, but am going to try to suck some solder (didn't have that before) out in case the heating up and adding a touch of solder didn't get it. But I don't really know which board to do it on, or which copper thingies are analogous to those in Wong's pictures. None of my components are horizontal "doughnuts" laced with wire as in that board. Does anyone have an f1903 that could tell me which ones are the likely culprit? Or maybe what surrounding objects I should look for in order to figure where the culprits are?
Sorry I couldn't post link to pictures of the boards as I can't find examples of mine anywhere. And I don't have a digital camera.
Good luck everyone!
Correction

The four thingies wrapped with copper on the beige board are actually vertical cylinders rather than horizontal, if that makes any difference. They look kind of the same but two have labels on the top, a different base, and some kind of silicone on them attaching them to something, or something. I'm so ignorant.
