    Smd wp9f

    I would appreciate knowing where I can find the data sheet for SMD components WP9F and WP9U.
    The 3 terminal WP9F, SOT23 component is from a RCA / Proscan LED TV.

    Thanks

    can we see a high resolution pic of the board marked with the location where these supposed to be? Also the model number of the TV and board.

          Yeah I am still around, just busy...
          let me guess... you don't have any panel power on that LVDS connector next to it, right? It is probably some lower power mosfet.

              I had the same thing happen on a diy lcd controller. I accidentally sent 12v to a 5v panel fried the lcd conroler and panel 5v regulator. If you really had to you could connect a diy lcd controller. Im just hopeing it didnt take out panel . if its a 12v panel i think it should be ok. Can u you get a pic of the lcd model.code?

                That wp9 P-channel mosfet is a WPM3407C The (F) and (U) sorry, are the month codes
                The (H)1A is a MMBT3904 I believe (H) is the date code

                  Yes sir that is correct.


                  Thanks for all the information

                  All the WP9*'s are the same type of P-channel mosfet WPM3407C.

                  I replaced a WP9F with a WP9U and the WP9U overheated and burned up.
                  Thanks for confirming the WP9F and WP9U are the same type of p-channel mosfet.

                    Please help with a blue screen on this RCA RLDED4633A-D TV

                    I have 5v standby
                    I have 12v supply

                    When the TV is turned on I only get a blue screen


                    The Power Button is working normally for on/off control
                    All other Control buttons have no control

                          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....

                          Hi guys
                          I have a sony tv that doesnt turn on but it gives me the white light followed by 4 blinks.
                          Power supply seems ok but was drawn to this regulator.I have seen these chips usually have pin 1 and 2 as input and output respectively. Just wanted to confirm this is the case with this chip. thnx
                          I have checked the backlights already and they all work.

                          Identifying a 'FS45' SOT23 device
                          by Nevillet
                          Hi All,

                          I'm trying to repair a PCB that has some surface mount SOT23 devices that apear to be transistors but testing them on the board are giving confusing results.

                          Its named FS45 but I can't find a datasheet that seems correct.

                          The device is used in 10 places on the PCB. In 4 cases they appear to be controling triacs and the attached picture it shows it connected to a BT136 triac with the FS45 connected to the gate leg of the BT136.

                          Can anyone identify the device and suggest an alternative?

                          Many thanks.

                          PS: I have...

                          by Lee M.
                          Hello all, new member here. I replaced the LED strips and found that the BL can be turned on with the TCON board and LCD panel disconnected. So new LED strips are working fine. Now the problem. There are 3 diffuser sheets on this set. One sheet is thicker than the others and I know it goes in first next to the LED strips. But one side of this sheet has a rougher texture than the other side. Does the rough side go up or down? The 2 thinner sheets have tabs that will only allow them to be installed one way so that's good. One sheet is what I would call plain translucent. The other sheet is whiter...
