        i'm replacing all the sam young caps on the power boards because none of them will turn on. should i replace all the Jamicon caps on the output board? or will even those cheap caps be good there for a while

              Awesome. I'll be fixing a lot. I'll be getting 15 Vizio's with bad caps a couple times a week. They're all 37"

                    Can you also use FM series on logic boards/main boards?

                      You can. But the usual culprit in the main boards on vizios are 1117 LDO voltage regulators. The tvs your getting that won't turn on, does the orange standby logo stay orage after you hit the power button. It seems the newer vizios are having corrpted eeprom issues today versus the bad LDO regulators of yesterday.

                        Most of them turn on, they just get stuck with the "Vizio" logo, and you have to unplug them to turn them off. It looks like some of the Jamicon caps on the logic board are slightly bulging.

                          If they turn on vizio logo goes white but can't be turned off unless the power plug is pulled from the wall would be a very likely candidate for bad 1117 LDO voltage regulator. Before you start swapping caps get a service manual and scroll down to the dc-dc converter flowchart and check voltages. These tvs could only need a 50 cent regulator.

                            Alright, I will. Just in case of a misunderstanding, the Vizio lights up white and you DO get a screen, it's fully lit up and bright, but it just says "Vizio" in the middle of the screen and won't do anything else.

                              If its showing a vizio splash screen and freezing then it's probably not the regulators. What are the model numbers of a few that you have gotten?

                                I'll check in a couple minutes, thanks for your help so far! I don't have any 470uf 25V Panny's, would UCC KY series work? that's all I have on hand. they're taller and skinnier than the Jamicon's.

                                  The KY series should be fine. The panasonic FM's have a higher ripple and a little lower impedance but either has to be better than the jamicons that are in there now.

                                    It doesn't hurt to check the regulators regardless only because it is a Vizio. Checking the regulators only 10 minutes or less. Well worth the time, if you ask me.

                                        All the voltage regulators on the main board. Search this forum for "U33 Vizio" and you will find multiple hits with instructions on how to test them and verify they are within specifications. I might have one or two posts in the threads.

                                        Like I said, checking them is easy and doesn't take a lot of time.

                                        This thread also talks about the corrupt eeprom as Mr Bill mentioned in post #11.
