    how to test eefl lamps?

    Hi,

    i have problem with 26 inch lcd tv. the 2 seconds to black problem.
    i inspected the 2 inverters but found no faulty component so far.
    so maybe there is a bad eefl lamp. I'm not familiar with them .
    there are 2 connectors with only 1 wire going to the panel.

    i have a ccfl tester, but i don`t know if i can use it to test it on the connector because only 1 wire , do i need to hook the other wire to ground ?

    or do i need to open the panel and test each lamp individually?

      Do you have the LCD panel model? There should be a sticker on the back, then you can look up the spec sheet for the panel, it will tell you the requirement of the lamps and the electronics.

          test active pfc power with lamp test
          by khelane
          Hello
          I have a big problem and that is that in some cases when repairing active pfc power supplies I cannot work with a test lamp. I can only get help with 5 volts standby and for starting and starting I have to work without a lamp and this way there is a possibility of parts exploding and other parts being added.
          Sometimes with a multimeter test the problems can be reduced to some extent, but I had several cases that had to be tested on and online and recently two varistors exploded. They had terrible resistance because the power supplies were over 800 watts.
          Is there a way...

          How Can I test PWM DM0365R?
          by chth96
          Hello
          I have power adaptor(220V/input, 12V 1.2A/output) which has symptom of fluctuating output DC voltage between 11.5V-12.2V.
          So I opened its plastic case and when switched it on, I heard constant tik tik sound from inside its PCB.
          I measured DC voltage between negative and positive pin of the largest capacitor(400v 10uf) and it was measured contant 300V.
          I also measured ESR value of all capacitors and I noticed that one of capacitor(KMG 16v 470uf), which located in the secondary side, have high ESR value(10 ohm),So I replaced it with same specification NXH capacitor....

          Mats / mods: detected and repaired GPU fault. Cant seem to test after!
          by chronic519
          Hello.

          GPU came in, green lines. Spent lots of time using to get the Mats / mods drive working (found on youtube).
          Found issue with a RAM block
          Replaced, green lines gone.
          Trying to test again, assuming getting the false positive. Originally had over 1K on a single bank. Now getting tosses low between banks.
          Used a good card to test and same results low errors 32+.

          I am just search for some form of command to do a full test on the GPU.
          I just ran the mats command with my good GPU and passed after roughly 40 min.
          The repaired one, ran...

          Tiny Tech ATX480W output power ticking
          by mikey5791
          Hi to all forum members,

          ​​​​​​This psu (Tiny Tech model ATX 480W) had been installed in a very old Windows XP PC but recently i pulled it out as the pc cannot start. To test it, i jumped the green wire and black wire on the 24 pin connector. The psu fan jerk a bit but not spinning. I used my dmm to check dc voltage on output connector wire, the 5v red wire keeps ticking a bit at around dc1v....then drops and ticking again around 1v. It is the same situation with the 12v yellow wire.

          Fyi, i desoldered the secondary side electrolytic cap those over 1000uf...

          New wire for my RDE3340 Whirlpool electric range
          by wnlewis
          OK. I got the rocker switch figured out thanks to the good advice on this forum.

          Now I need to figure out the correct wire to go to the switch from the broiler element and from the oven element.

          This is a Whirlpool RDE3340 electric range.

          The common wire on the switch appears to have a high temperature insulating material. I am guessing that both the wire to the broiler and the wire to the oven elements also need relatively high temperature insulation. What do I need to look for? The broiler is rated at about 2400 watts.

          Where may I find parts...
