    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.

    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.

    Could use some help, trying to fix HP 1940 LCD

    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.

    Topcat's Budget Telephone System- Panasonic KX-TA624 Conquest
    by Topcat
    About 10~12 years ago I was given this Panasonic KX-TA624 analog telephone system with its 'master phone' and box full of extension telephones. It's been up in the attic all this time, untouched/unused since I didn't have a land line. It has all the line expansion cards, making it able to handle up to 6 outside lines and 24 internal extensions. I was told this system was removed from a shopping center that upgraded to a VOIP system.

    Why am I wasting my time on this you wonder? Well, I need a phone number for a little venture I'm working on....and I sure as hell don't want my personal...

    Monitor HP-1940. PSU - BEN 48.L1G02.A01
    Hallo! I carefully check all the tips. At first there were bad transistors C5707 I chaged them, but after few hours problem repeated. I changed all capacitors and resolder transformer solder. And changed transistors again, but two of them all the time "blow".
    Fuse is ok.

    Picture: http://*************/photo/my-images/10/dscf3309s.jpg/
    Some of capacitors are larger then original, but it's just becouse I could not get the right rated voltage so I took higher voltage caps, but the same capacitance

    Hp 1940 flicker
    by terminatorX
    I have one hp 1940 (Benq 48.L1G02.A00) that when plugged to power starts flicker rather rapidly and just keeps doing that. To mention not connected to PC. The power led is on.
    It's not originally my screen so I can't really say anymore in the symtoms department and I removed the power board from the inside now. Nothing really seems to be blown or damaged, no bulging of capacitators. Is it the usual C5707 transistor problem?

    I have googled alot and found a couple of threads here but decided to make one thread of my own.
