    Technika x22/14c Backlight issue..component part number

    Hi

    Got the TV with backlights shuting off after 2 secs, the two caps have blown on the inverter, took a guesstimate and put some 10pf 3kv caps in, tv booted up and was happily playing away for a few hours, turned it off and on a couple of times no problems, then tried turning on nice little crack and the problem is back.

    I have no schematic nor an idea of what size caps are supposed to be in the inverter, any ideas, should I go with 10/15pf 6kv

    Thanks in advance

      3kV is quite small, I would try 6kV for those caps, I know budm usually uses 5~6kV caps.

              Sorry, would you stick with 10pf??

                  10pF seemed to work the last time... no idea what the originals were??

                      No both blown out the board, cant find any info, have been cheeky and asked an ebay seller to read them off but no response :o(

                          Could try the trick "trying to verify if my boards are compatible, as have heard they were also produced with 22pF cap" Has worked before for me.

                                  Just read on another forum post with the same inverter that they are 9pf 3kv, so I have another fault with the TV, I do not think its a ccfl tube as I have had the tv running with no dim lines, for quite some time.

                                  Will have another look now I am not sure if one of the ccfl leads shorts to the frame as the wires do look quite tight around it.

                                      Fitted new 10pf 3kv caps just in case and it was still the same, replaced the two 16v100nnf caps and everything seems to be working ok

                                          this tv is throwing me for a loop. do samsung tvs no longer have the backlight self test feature built into the power supply?
                                          i tested the backlight with my LED tester and it lights up both strips. one of them reads 100v and the other reads 63.7v.
                                          unplugged mainboard from power supply but left backlight plugged in, and then plugged psu wall power in. expected to see backlights light up but see nothing.
                                          according to how ive diagnosed in the past, this would almost always be a bad power supply. replacement power supply was cheap like 20$ from ebay. but still i get not even...

                                          Hi There!
                                          I'm trying to help my friend who owns a restaurant be just bought.
                                          He has a very long LED strip running along all the walls and columns. The strip is attached facing down 2in above the floor, using a wall panel that ends in a metal rail that finishes the panel underneath
                                          It's stuck using, I guess, the 2 sided tape that comes with the strip
                                          The issue is that like 1/2 of the full length, including 1/2 one wall, another entire wall, and one column, flickers after 4 or 5 minutes ON. Particularly it flashes staying OFF most of the time and flashing ON for 1 tenth...

                                          by G-Sting
                                          So My iPad was not charging and booting up . i went to a local technician and he checked with thermal and this Part marked in 1st Photo is Short.
                                          So then i went on to boardview and downloaded the schematics and identified this part in 2nd Photo. Now i am confused what exactly is the part called ? where should i get this from ?


                                          i contacted my technician and he sent me his BoardVIew screenshot in 3rd Photo. In his Boardview the part is called X2826.... Something

                                          SO My main concern is what part should i order what should i search the name for ?
                                          on Ipad...

                                          Guide me through repairing a Dell p2210f LCD ccfl backlight monitor
                                          by DanPoka
                                          I bought this p2210f dell monitor to fix. Schematic is the same as p2210.
                                          Behaviour is that monitors comes on but then backlight switches off almost instantly. If I look with flashlight I can still find the "No signal message". So definitely a backlight issue. Trying to advance the issue I proved that the protection circuit is switching off the backlight by shorting out C3 and resistor to disable the INL chip then re enable by removing the short.
                                          This is where it gets interesting. When I disassembled the monitor to solder leads on c3 capacitor I noticed the backlight flickered...

                                          Hello all,

                                          Am trying to figure out this backlight issue with this A1990 Macbook Pro.

                                          Tests performed:

                                          There is no backlight even with a good screen.
                                          Backlight IC is receiving the correct support voltages.
                                          Fuse F8400 ok
                                          Current sense resistor R8400 ok
                                          Backlight IC is receiving 3.3V on enable pin.
                                          Backlight IC receiving voltage from PPBUS_G3H, aprox 12.5V.
                                          Backlight IC receiving 5V from PP5V_G3S
                                          Backlight IC BKLT_SCL and BKLT_SDA both measure 0.545V diode mode to ground
