    Westinghouse LD-4655vx - I think I just lucked out

    Bought this from a guy on CL; the ad is still up (http://kansascity.craigslist.org/ele/3919422549.html). I talked to him on the phone and he seemed like an ok guy. He said it wouldn't power up, so I am thinking power supply. So, I go do some research and it uses an external, laptop style, power supply. But, I feel surely he tested it before buying a new tv.

    I call him and we agree on $50. When I get to his house he has the tv, manual, and remote waiting for me, but not the power supply. I ask and he says, "Aw yeah. I knew there was something I was forgetting." and he goes and finds it. The way he forgot it made it seem to me like the thought never crossed his mind it could be the culprit.

    I get home and test it, and sure enough it is dead. I tested a few other power supplies just to make sure I wasn't goofing up with the technique. Ordered a new one for $15 online. Here's to hoping it is that easy of a fix.

    A more common fault with these is the LED strip shorting out to the chassis damaging something in the TV eventually. Usually have no light from screen but power LED works. Repairable, though, if the power supply is not at fault.

        Was your power supply dead, also?

          I just picked up this TV yesterday as well. Guy had already replaced the dead supply but that wasn't the original issue. It powers up by unplugging one ribbon cable as noted in the other thread on here. I'm positive its the shorted out cable problem but it was getting late last night and I didn't have time to dig any deeper in to it.

          I'll be following the leads in this thread:

          https://www.badcaps.net/forum/showth...ight=LD-4655vx


          I'm certain the supply was originally killed from being plugged in for an extended period with the cable shorted out.

            Aaron, is there any point in opening it until I get the new power supply and see if it fires up? I don't really see one. I would have the check the amps, but I highly doubt I could use a laptop power supply to test it.

              Plugging in a new power supply may quickly damage it.

                So you are saying I should open it up? How can I test it if I have no way to get power to it. The power supply I ordered is for this tv. Are you saying I still shouldn't use it?

                  Mine survived some brief testing. Not saying yours will or will not but I wouldn't leave it plugged in if it doesn't come on immediately. If it won't power up, unplug and follow that thread I sent to check the ribbons going to the backlighting. You can unplug both ribbons to start and see if the unit powers up. If it does, proceed to connect one then the other and attempt to power up each time to verify which one is shorted.

                  Go ahead and read through that other thread now regardless to get an understanding of what may be happening.

                    I guess I did luck out. After opening it up and not seeing any problems with the ribbon cable, I plugged in the new power supply, and boom!

                      Nice, do check the display has even intensity.

                        It does. The picture looks great. If only I was good at selling tvs on craiglist as I am at fixing them. I now have 4 to sell and my wife is giving me the business about it.

                            I will check on the PS. I got it here:


                            Looks good. I might keep it.

                              Ok, so I know I know, it's a Westinghouse....lol It's got the backlights but no video. Likely the panel, but I'd like to take some measurements on the buffer board with help from you experts to confirm. See the attached pictures. In pic #1, there's a nice pin reference to use to take some measurements. The large IC in pic #7 gets up to 60degC when the TV is on.

                              So, backlights, no video, go! 🙂...

                              Westinghouse 32" Smart TV (Model: WD32HBR105) . Originally stuck on logo with no response from remote and no firmware file available to flash via USB. Westinghouse Support stated it would require service but that wasn't a cost effective option. I used dental floss to remove the motherboard processor heatsink to identify what make it was (Mstar). Unfortunately that knowledge didn't help with a solution. After the heatsink removal it only displayed a completely white screen. I then decided to replace the motherboard with a universal 3-in-1 board but the white screen problem continued. This...

                              Hello all!

                              Westinghouse TV WD48FAB100 Not Powering On – Burn Mark Found on Power Supply .

                              I have a Westinghouse LED TV, model WD48FAB100 that is not powering on. Upon removing the back cover, I noticed a burn mark where the AC cord connects to the power supply/main board. In this model, there is only one board combining the two functions. Previous owner said the TV experienced a lightening strike, but who knows. I checked the main fuse, tested OK. Here are a collection of readings from the power supply ports. Looking for some guidance on what to test/check next....

                              Hi All... Me again. Begging for help. The guy who now believes it's possible to fix a TV (one of the millions) one can find on the streets of NYC. I hate hate hate waste...

                              Thanks to y'all's help I fixed and am happily watching a 70inch Sharp Aquos. Perfect. Learned a lot, replaced LEDs. Pulled screen/panel. Proud.

                              This is a newer set. It's a Westinghouse Roku WR58UX4019. It was RIGHT outside my place literally, and I couldn't resist. 58in. 500$ new, but I'm not a rich man. So, I want to try.

                              There is sound. It turns off and on. Screen is black. I can...

                              by flashcoder
                              Hello,
                              I got this TV (Westinghouse DWM40F1G1) that did not came on one day, blinked for a split second and turned off. I looked at it closer with flashlight and figured that the TV actually works, its just the backlight that does not.
                              There is one PCB board - all of the components are on it: TP.MS3393.P85

                              I took my oscilloscope and looked what is coming to the MOSFET that is switching current to LEDs - I could see that the PWM signal comes in but it cuts off almost instantly. I thought its the driver chip OB3350CP and so I replaced it.

                              After that the...
