    Re: Vizio vp322 hdtv10a

    this is all beside the point though if u have found the best all around caps to get which are the panasonics...
    do they stock them here and im just blind?

        I don't know if badcaps.net stocks them because I've not ordered from them before, being in the UK. Tried digikey? Badcaps.net store is more for motherboard repair than power supply repair.

            almost there but im having trouble finding just one of these caps:

            the samwha 16v 100uf 11mmx6.3mm lists impedance as 0.15

            but in the panasonic fc and fr series the only equivalent is 0.3 impedance
            the rubycon yxf is 0.4
            and the panasonic fm doesnt exist in 16v 100uf apparently...

            is .3 ok compared with .15 even though thats double the impedance?

              For a small 100uF yes that should be fine. Significant ripple current not expected.

                      Because PayPal take 3% extra... AND they don't let merchants pass this cost on (as e.g. a PayPal payment fee +3%), so they have to roll it into all of their payment methods.

                          Yes, a leach on the industry IMHO...
                          Merchants SHOULD pass on payment charges to the customer (and no more, just the exact rate)
                          That way there would be competition for these companies to offer lower interchange fees...
                          Right now it's actually ILLEGAL for a shop to charge extra for using a credit card, what the hell?

                                wouldnt u know, i found another one of these TV's with some minor screen issues but all the boards are fine. swapping out the working psu I know now that my other 2 tvs are just fine...when the parts come in ill have 2 perfect ones and one with a minor screen issue (burn in) is there any way to reverse the screen burn in on plasmas?

                                  It depends on the circuit and what function the capacitor is performing there.

                                  Low ESR is good for switching power supplies because it means the capacitor dissipates less ripple as heat, meaning it stays cooler and thus lives longer.

                                  But switching power supplies are tricky circuits to design, and require rather tight tolerances on components. You already know what happens when the ESR of a capacitor gets too high, or the capacitance reduces. The PSU outputs are not filtered properly anymore and the power is full of ripple and noise, which results in improper circuit operation or even damage to the load.

                                  In some cases the PSU becomes overworked trying to compensate for these bad capacitors and can itself become damaged due to overheating etc.

                                  If the ESR is too low, a similar thing can happen. Filter and feedback circuits which were designed for a capacitor above a certain ESR value do not operate properly when the ESR is too low. This leads to improper PSU operation, stressed components, and ironically, higher ripple and noise.


                                  So when you are selecting new capacitors, it is a good idea (in most cases) to choose ones which have an ESR value close to the originals. It does not have to be exact, though, and a replacement with a bit lower ESR than the originals is preferable to one which is higher.

                                    I need to find me one of these, as far as burn in repair... Not likely fixable but you can put it on tourch mode and run a pixel shifting or a screen wipe for a hour a day.

                                    Disney WOW bluray has all this stuff for TV/Audio calibrations and what not.

                                        Torch mode is vivid/dynamic setting with contrast/brightness/cell light/ or what ever makes the screen bight as possible (all settings set to max).

                                          ...so wait...i have to get a blu ray player and this disney disc...and it can fix the screen burn? is torch mode something i can do without that? how do i access such a setting?

                                          err is it just setting everything to max brightness and displaying a white screen?

                                          for how long?

                                            by Tynan Dill
                                            I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                                            Upon bringing it home and plugging it up, it showed a standby light.

                                            I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                                            The screen seems to blackout and stay black, but with a flashlight I can see the display.

                                            With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                                            Assuming...

                                            Hi.

                                            picked up another TV. This time is a Vizio M65-C1. TV does not turn on. I had repaired another 60 inch vizio , Bad main board.
                                            When power button is pressed, the Power led indicator on the bottom right, turns for a few seconds and then it fades away. No backlight or Vizio logo on screen. Removed back cover and repeated test.
                                            This is the TV This TV is a little different from the Samsung I have worked on. Power supply is on the Left side, Main Bd is on the right side, T-CON , not in the picture is on the bottom. I am assuming that the boards in the middle are the LED...

                                            Failure Symptom



                                            No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.

                                            Where is the short?

                                            Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.



                                            Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but...

                                            Vizio SmartCast TV software bug that looks like hardware
                                            by howardc64
                                            Bug looks like hardware so thought I posted it here. Exact same behavior on 2 different model 4K Vizio TVs running their SmartCast smarttv software. After launching youtube app, press vizio button on remote to return to the smarttv menu, once in awhile, a column of bad pixels will show for few seconds on the left hand side.



                                            It seems the vizio software is reinitializing hardware when returning to the smarttv menu. In general, SmartCast software isn't very good. Also will randomly (relatively infrequent) get no network connection when on wifi and require reboot....
