    Re: LTV32 w1 westinghouse tv

    Transformer pins are constructed of steel pin plated with copper, sometimes this a issue. Trust me.

    How I found out? They are magnetic and once halved a dead flyback transformer and polished it smooth, this happened to be one of pin got polished as well... showed a layer of copper plating on the steel pin.

    Very cool to see how a flyback transformer looks like once you get it polished smooth to see individual turn of the magnet wires, clearly even on high voltage section.

    Cheers, Wizard

      I've taken care of my problem(s) - the picture cutting off was indeed the cold solder joint at C301; the sound "blipping" off is a fault in the comcast cable box.
      I contacted WX Digital and have been promised communications with one of their engineering staff. When I get an answer, I'll message back.......

        WX go-to guy called me back - engineering couldn't help me because of the "reverse engineering for the blue power-on LED." Sounds like a bunch of hooey to me.
        Would someone with a functioning power-on LED trace the source of the power to it, maybe post a photo of the board? I just can't believe that there's not something very simple that would help me to enable functioning of my LED.................
        A source for schematics would be REALLY helpful !!!!!!!!!

I know that it has the ABILITY to work since it flashes on whenever the set is either unplugged or plugged in to wall power. The remote sensor on the same board works just fine. I've taken a photo of the board [attached] and even though everything SEEMS to be OK, the silk screened area under the capacitor shows two mounting possibilities; I'm wondering if a different capacitor of whatever size would "enable" the light. I want it to work because without it, we sometimes need to push our power on button on the remote several times before we see backlight and the input source graphics.
          Any ideas???
          Thanks in advance.............Dave H.
          If the unit is working, the Blue LED light can be controlled via the television software. If you want step by step instructions on how to turn it on, let me know and I would be glad to go through it once I get home tonight.

          I realize it might be a different problem for you, but if you are able to, I suggest trying the software approach; it might be as simple as pushing some buttons

            That's a very good point - I can disable the blue led in the standard menu system for my LG TV - take a look!

              That would be great but I must warn you......the WX tech support guys had me go through the drop-down menu for the settings and there is no on/off setting. If there's another way, I'd be glad to give it a try and, thanks in advance !!!!

                I know it probably doesn't help you, but for the hell of it:

                Menu > Option > Power Indicator:
                Standby Light: On/Off
                Power Light: On/Off

                  Thanks for the try, Sean. My WX menus do not include a setting for turning the indicator(s) on or off - that would've been the simple way around this.
                  Somewhere out there, there must be a schematic floating around; it's almost like trying to scare up a unicorn - you've heard that they exist(?), but no one's ever actually SEEN one..............

                    OKAY! i am new to the site and to be completely honest I don't know a whole lot about electronics but i can definitely take something apart! I have my tv in pieces and want to thank you guys for posting up all the info! Using your experience, knowledge, and pictures i found a cracked solder joint (c301 i think) NOW i just have to try and solder it again... This should be interesting!

                      Same here, I just found this thread when Googling on the power supply for an LTV-32W1 , and the pictures from the OP convinced me to take the power supply out (I'd heard a popping, but thought it was either a short or transformer)..well C310 (J on top) right next to T1 has a bad joint. Same lead as the pics on page 2.

                      What happened here was that when you left the TV plugged in, things would heat up and about 5 minutes after turning on, it would just lose sound and video (LED still blue). I took the back off, powered it up, and it worked, but did same thing...just quit while I was checking 24v power for inverter...I turned it back on immediately, heard that pop, so I thought it was a short, but it was that joint I guess.

                      So I'm off to solder it, and reassemble.

                      Update: Still working so far. Thanks forum. (I'm going to have to find some more of these to repair) : )

                          man, im gonna buy every one of these tvs i can..

                          $35 investment and $.25 worth of solder fixed her right up. Had cold solder all over but broken bad right at that black component just like everyone else.

                          I have the box and everything. This should be an easy flip.

                          badcaps comes through again!! I LOVE this place!!!!

                              I was having the same symptoms. My board also has a cracked 310. Also had to touch up a couple others. Now I have sound, still no picture. Any ideas?

                                Wow, thanks for this information! The C310 solder joint on my LTV-32w1 was cracked exactly like yours. A touch-up with my pencil iron, and it's working fine!

                                Thanks again!

                                          Hi - I dont htink you can expect much help resurrecting a 2year old thread. You can use the thread but need to start again. This is what I ask of new members.
                                          Welcome to the forum- Please update the mains voltage in your profile.
                                          We can help a lot more if you please post good clear pictures of the whole chassis, and then pictures of each board, front and back and close up of connectors, (max resolution 2000x2000 and 2MB) using the manage attachments button, which is found by clicking "go advanced" under quick reply.

                                          Please do not post inline and offsite as they slow down the loading of pages.

                                          Examples of what is needed

                                          It will be useful if you can say what the supposed fault was, what you have done tried so far and a bit about yourself - skills tools etc.
