    Identify Source of CCFL Reflector Assembly

    Greetings BadCappers:

    --I found a bunch of partially disassembled CCFL LCD screens and parts. Would someone please help me to identify the part in the picture below. It is a reflector which measures 424mm, it contains two 2.0mm CCFL tubes that appear to be about 420mm long. I assume it came out of a 20" monitor, but I am not sure. If anyone could tell me what it most likely came out of, it would make it easier for me to sell on eBay to support my electronics hobby. I donate 10% of all sales to the Marine Corps and Law Enforcement Foundation.

    Re: Identify Source of CCFL Reflector Assembly

    Meaurements are the Glass part ONLY,not the silicon bits on the end,and that would give a better idea of what they are from..eg a 19" standard screen would be about 385mm and a 19" Widscreen about 417mm.. hope that helps,As you are aware the CCFL's in the photo are no good, and the Reflector channels vary quite a bit in width..
    hope this of some help to you.

      Dear Rtech:
      --I have 2 of these reflectors with 2 lamps each in them. When I tested them, one of the lamps would only light partially. I discovered that the solder connection had broken off and taken most of the wire with it. So while the bulb was still good, there was just not enough wire to reliably solder to. That lamp and the reflector (the one in the previous picture) was discarded. I managed to get the other lamp out of the reflector and obtained a much more precise length measurement of 416 mm ± 1 mm, so it would appear to be from a 19 wide screen.

      --The other bulb (one of the ones you questioned) still lights up just fine. How did you know there would be a problem with those bulbs? Both bulbs in the second reflector light up just fine. I gave the reflector length (not width) of 424 mm, so someone could measure theirs to see if we might have a match. Thanks for the help. I will put in the ad that the reflector likely came out of a 19" wide screen display. Additional pictures attached below.

      --By the time I take these out of the broken display, test, measure and pack them and then sell them for 3 or 4 dollars each, I am probably making a dollar an hour after months of waiting. I recycle all of the metals from broken units. This activity keeps me entertained (I am retired), helps support my hobby, and reduces the load on the landfill. I want to thank all of the Badcaps folks for helping me in my repair and recycle efforts.

        LCD Connector identify or source
        by reformatt
        Trying to identify where to source the LCD connectors on the motherboard side for a HP 14-cf2051la. This one came in with liquid damage to the connector and the flex cable. It appeared to clean up ok, however customer says that display blanks out intermittently. It's a 30 pin EDP flat ribbon cable on motherboard side. Believe it to be a HEDWIG-6050A3155301-MB-A01 motherboard.

        I've stolen the connector from another HP motherboard which matches up but it's not the best since it's been kicking around my donor pile for a while. This connector is different to most flip type ones I have...

        Asus X532FL 3.2V at source and gate
        by Lvsitano
        I am having some trouble with troubleshooting a Asus X532FL rev 2.0 motherboard, which does not power on. So at the first MOSFET, I am getting 19V at the drain, and then 3.2V on both gate and source (compared with ground). Of course, the 2nd MOSFET's source will have 3.2v at source.

        First MOSFET is a QM3056M6 and 2nd MOSFET is a QM0930M3

        I already checked first MOSFET and source and gate are not shorted (drain with source not shorted either). Also I have 1.7V at the LDO rail (measured at the keyboard connector, as the power button is on the keyboard).

        First...

        Help on Samsung Syncmaster T220 dead ccfl lamp
        by mikey5791
        Hi,

        This monitor previously is my main working monitor which i have been using for 8~9 years. Yesterday, when i switched on my pc from fresh to power on, the monitor is just black no display. I started dismantle to look inside the monitor power board but nothing looks suspicious or burnt. So i took my external ccfl inverter to try to power the monitor ccfl lamps which consisted of 2 lamps on upper part and 2 lamps on the lower part.

        Found out the upper ccfl lamp which is supposed to connect to cn304 on the power board did not light up. Then i installed a used working...

        HANNSG Hi221 -- 2 secs to black feat. CCFL flicker & "burn" marks on power board
        by ttmi100x
        Greetings everyone,


        I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...


        The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
        Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.

        Upon closer inspection...

        Problem

        This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....
