        I am working on a Westinghouse TV with board DAC-19m015. It has a nice little burn spot where L105 used to be. Can anyone tell me what is supposed to be there? Thanks in advance. :-)

          L105 => L => inductor.

            Agree. L is for an inductor. You can see one in one of your pics ...

              That's what I thought, but I wanted to make sure. :-)
              Since L105 is gone is there any way to find the correct inductor to replace it? Any ideas are welcome.

                I had thought of searching for the service manual for the monitor and other monitors that use the same power supply. The I realized that a considerable amount of current passed through that inductor to destroy it AND damage the circuit trace next to it. There is certain to be additional damage.

                  Good Point. Thank you. I will probably look for another board.

                    I may have missed it, but is there another MOSFET than can be used? Both Mouser and DigiKey show the 863-NTP45N06LG part as no longer available.

                    Thanks

                      Hello! I believe the original mosfet was a 40T03GP. These are readily available on Ebay.

                            Another question about my DAC-19M015 power board.

                            On the solder side, to the right of the CE103 cap (1000uf, 25 vdc) (with the cap positioned to the top), there's a small black square labeled ZD100. It appears to be cracked.

                            Can anyone tell me what kind of component it might be, and the value?

                            Thanks

                                Could someone help me identify this diode? I have a couple of these that are shorted. I've replaced all the capacitors, 40T03GP MOSFET and checked all fuses. I found several SMD resistors that had very high resistance (0.2 ohms -> 1.9 megaohms) along with these shorted diodes.

                                I believe these are LL4148 diodes, but I would like someone who is familiar with these to verify. Thanks

                                  After some discussions on another board, it appears that the prefix 'zd' stands for zener diode. We're guessing a 12 volt, 1 watt zener should do the trick.

                                  I had emailed Delta Products about this board in hopes of getting a schematic and/or a parts list. I got back a fairly curt (snotty) reply basically telling me to take it up with Westinghouse. And we all know how they are.

                                    It should be pointed out that this power supply - indeed, the entire monitor, is sold under a number of different labels.

                                    Two sites that can be helpful are www.elektrotanya.com, which has a number of service manuals. Their 2 downloads a day limit will be lifted if you register.

                                    Also, http://www.4shared.com/dir/7126951/4..._INVERTER.html has a number of original and third-party schematics for power supply / inverters.

                                      Thanks for the links, Bill. I think I can get the power board schematic if I can ever come up with another model number. I thought I had it with a Viewsonic monitor, but it turned out to be a Delta DAC-19M010 unfortunately.

                                        This is a constant problem. Quite often we will find several different power supply / inverter boards and even logic cards used in a given model of monitor.

                                          I have this same monitor: Westinghouse L2046NV. Same issue... but once I replaced all the caps and the mosfets, it still didn't work. The backlights would flicker for a second, and then go out... over and over. I finally found R210 (on the backside of the board) was bad. Ohm'd out it read 900K ohms... and it should be 10 ohms. Reads: 10R0. I replaced it and it fixed the issue. Just wanted to throw my two cents in to help others if they have the same issue. This one was killing me for a while.

                                          Thanks to all those on this, very long, thread that have helped... the info was a great help to me.
