    Can someone help me identify value of this component from Sony Tcon board. Thanks

    Hi

    bit of a long shot, but here is the challenge lol. Can anyone help with the value of this regulator ic I have circled in the attached picture. Markings cant really be read but what I can read is its marked 50 in the small circle in the middle of the ic. I need to change this component but cant figure out the value and what to change it with.

    Thanks

      Is there another one of these components on the Tcon that could help you identify it?
      Willing to help but I'm no expert.

                  If you can't read the markings buy yourself a jeweler's loupe or pocket microscope off ebay.

                          The way it is connected, it looks like MOSFET.

                                  It's a pity you don't have one of those cheap component testers / identifier and then you could check one of the other identical devices.

                                          Hello everyone,

                                          I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the...

                                          Sony KD-55X9000F TCON Issue
                                          by thelankanguy
                                          The TV shows a black screen with no image.
                                          TCON ribbon connectors were disconnected individually for image and there was no half image even.
                                          Later both ribbons were disconnected and TCON voltages were tested.
                                          12V, 3.3V, 1.8V were seen present but VONE signal reads 0V.
                                          There is also a short to ground in this circled inductor.
                                          Is this a TCON issue or something else ?...

                                          Hi,

                                          I have this problem with my Sony 55' AG9.
                                          It flashes 4x.
                                          I have found the service manual, and seems it is the TCON.

                                          Before I buy a TCON can someone check the vid?



                                          Thanks in advance!...

                                          Help to identify chips on Sony SRS-XB43
                                          by maleksa
                                          My Sony SRS-XB43 won’t turn on, won’t charge (no LED light when plugged in to USB charger) and won’t run on batteries. I tried changing batteries but no luck.

                                          I am trying to figure out the cause of the problem and I need help to identify two (2) ICs, which are U4 (with marking CKUCFA) and U6 (markings MPMS9428A643). I have attached a picture.

                                          Appreciate any help or pointers....
