    Smd wg4d

    I would appreciate knowing where I can find a data sheet or any information on a SMD component WyG4D or WG4D.

    The transistor / regulator was installed on the main board in a RCA RLDED4633A-D television.

    WyG4D or WG4D


    Thank You

      The one transistors in the red square is MMBT3904 (H1A) The burnt one is likely for VCC_Panel, it should be a fet, ME2325-G, some use WPM3407

                  R_J, do you have an address to where I can get the SMD conversion codes for components like the transistor H1A?

                  H1A = MMBT3904


                  Thank You

                      Not really, search for "smd codes databook" there are a couple smd code books around, for the transistor search google for sot23-3 h1a

                          The smd code books I've found have not been much help.

                              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....

                              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...

                              60LN5600 white reflective sheet
                              by lfhlaw
                              So I had to replace the LED lights on this TV and that worked out nicely. But the White reflector sheet that helps to diffuse the led lights evenly was glued into the back chassis which had to be removed to replace the LEDs.

                              Placing the white reflector sheet caused it to not sit evenly - causing weird diffusing when TV was all put together. Picture is still decent, but now there are dark and light spots due to the white reflector sheet not sitting against the back chassis.

                              Anyone have thoughts on replacement white reflector? or do I just scavenge broken TVs for...

                              Intel PC hooked to X90L television picture cut-off
                              by Jackching
                              I have my Intel PC hooked to my Sony X90L television and each time the power is cycled on the tv, the bottom of the PC screen gets cut-off. Only half of the taskbar shows until i go into display settings and cycle the display size and it'll work fine until the next time I power off the tv. I updated the drivers. The graphics is UHD 630.

                              Hi,

                              ​​​
                              I am attempting to repair my television. When I turn it on, it seems to start normally and then the backlight turns off after a couple seconds.

                              Initially on the main power board I replaced diode D1202 which was shorted, and capacitor C1201 which was bulging. I was still getting some wonky voltages, so also replaced C1204, C1250 on the main board, as well as the filter caps on the LCD module, which were 3 680uf caps in parallel, which I replaced with 2 1000uf caps in parallel.

                              The tv is still showing the same symptoms, although now...
