but I eager to learn and have learned 1 or 2 things about repairing some basic stuff.

to help you get started with the basics. It explains how to use the multimeter, take readings, and things to check.

Your english is a lot better than most posters here who write in twitter style or without punctuation.

Well I had some help with spelling with Google :P

There is no problem with your English. It's obvious it's not your native language - it's too well written.

Pictures are a big help. We prefer as close to 2000 x 2000 pixels. I prefer a single shot showing the entire top of the board from directly overhead, and a similar shot showing the bottom. Three out of focus close-ups of the same capacitor are seldom useful .

Above all, attach them using 'Manage Attachments' (below the text entry area). Do not post them inline; it inconveniences those with slow internet connections and irritates the rest of us.

Hi there.
I know this type of LCD has been discussed here before, but they are old threads that I did not want to wake up and they didn't appear to have my exact symptoms.

I have few HP 1940 LCD's here that came from local company,
I'm not sure what it was that caused them to break, but I would point at the
power surge demon

Any way, they all seem to have the "same" trouble's, as in
having the 2 sec blackout and others have "flickering" (blinking on and off)

I've taken 1 apart and by quick inspection there seems to be no visible problems on it, other than from "normal" heat brownish dots.

Just to clarify it now, I have almost no experience in repairing electronics (as in testing transistors or knowing what is transistor and what is rectifier),
but I eager to learn and have learned 1 or 2 things about repairing some basic stuff.
English is not my native language so I apologize for any error's or wrong word use.

Pictures will come soon as the camera has finished charging.
