  • Re: another Samsung 2233

    postscript, I need a decent DMM which can measure low R values!

    0.2 ohms does not equal 0 ohms!!

    this can help:

    think I'll make a 100mA CCS with an LT3092 and a couple precision resistors 2k/20k and a 9v batteryRe: another Samsung 2233<br /> <br ...> <br /> think

    replaced all the (low voltage EL) SAMYOUNG caps, only $13 from Norvac, but not my favorite brands, which I was ready to order from Mouser for $3.

    IT LIVES! THANKS ALL!

    I may not have the resolution to measure 0.2ohms, my cheap DMM doesn't have a zero knob or calibrated leads but the primaries read identically (0.4 ohms) P2/P2, P3/P3 and P2/P3 so it looks like continuity to me. If shorted primaries are unheard of, secondaries which seem to be ok by R measurement are more common right? I plan to replace transformer regardless, and caps too. Bad CCFL is always a possibility too, unless I test with good inverter.

    thanks for the tip on image hosting, I know of no other site which does this

    another Samsung 2233

    bought from Dell in part because of its 3y warranty , but now Samsung says its 1y and back light failed at 2.5y

    started to flicker a few days back, went black a few times and then re-fired. Now it flashes on and off and then goes totally black although display is still visible with a bright light.

    board is different than most I have seen.

    2 fuses (circled) at least not tiny pico units and test OK. Pulled all the SAMYOUNG caps and they all test ok...
