    The problem is simple its the eeprom that needs replacing. It sends the signals. Check voltage on eeprom

      It looks like U702 was changed before I would test that regulator.

        Which EEPROM and is this the same as the E320-A0?

        I have a E320-A0 with sound, no picture.

          Hello everyone! I know this thread is old but I have another question. I am having the same issue. The TV will not power on at all. No lights, nothing. I am testing with a volt meter on the rainbow colored set of wires going from the power board to the main board and I am not getting any volts. Any info here would be greatly appreciated.

              There are two vesrions of the power suply board used in the same model TV and they look almost identical, so your board is the EXACT match to the OP for sure?
              See SJ for the exact model you have.

              Partial part number (CL801UXE3) can be found on a sticker.
              Partial part number (CL801UXE3Q) can be found on a sticker.
              We are going to troubleshoot using the pictures, so the correct pictures are VERY IMPORTANT!.
              BTW, the main AC fuse is good, and you are getting 160VDC or so between the two legs of the main filter cap?

                    OK, your board per sticker is 'CL801UXE4'

                    Board is $25. So what do you want to do?

                      well, I want to make sure that is the problem because I have been seeing the same symptoms and the issue was a bad EEPROM

                        What did you use for GND for the meter?
                        When checking in coming AC to the board, you have to measure between LINE and Neutral.
                        DCV measurement in the primary side circuit, you will use the negative leg of the main filter cap as the GND ref. for the meter.
                        So what DCV do you have MEASURED between the two legs of the main filter cap?

                          But you have to have at least Standby Voltage to run the main board first, so you have at least one problem dues to dead power supply which you need to get it running first then you can find out what other problem you may have beside the power supply board.
                          What is the history of this TV?
                          Bad EEPROM will not cause the power supply not to put out ANY Voltages.

                            Your last post may be a touch over my head. I have the dial on 200V (wavy line over the V). I touch the black to the GND on the 13 pin rainbow wires and I touch the red on the metal of the fuse holder.

                                tv history. my friend had it for 3 months and one day it just wouldn't cut on. he just gave it to me to look at it. I am now getting around to it. He said he didn't notice a storm or surge around the time it stopped working

                                  You CANNOT use the COLD SIDE GND or Chassis GND as the ref for the meter when measuring the incoming AC, you have to measure between Neutral and at one end of the fuses at a time.
                                  Why don't you just check the DCV between the two legs of the main filter cap?
                                  BTW, do not touch anything on the HOT side of the board or you may get killed.

                                      Why don't you just check the DCV between the two legs of the main filter cap?
                                      BTW, do not touch anything on the HOT side of the board or you may get killed.
                                      Is that the long black horizontal capacitor left of where the plug goes?

                                        I have a soldering iron, solder and copper thread.

                                          C9810 is the main filter cap.

                                            PS5 digital / No Power / No Beep / Good power supply
                                            by MisterAIL
                                            Hi everyone,

                                            Brought a non functionnal PS5. Apparently only a bad PSU...
                                            No beep, nothing.

                                            After some tests i found this :
                                            - PSU is fine (12 volts stable)
                                            - 12 volts line is shorted
                                            - DA9065 was fried, F7003 also => Replaced both of them, short is gone on 12 volts line, no dead short anywhere else.
                                            - By the way, nothing change. No signal, no power, no beep.

                                            - 12 volts, 5 volts, 2 volts, 1,15 volts are presents (suppose new DA9065 do is...

                                            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...

                                            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...

                                            Hello,

                                            Dell Latitude 5420 P137G
                                            Board: LA-K491P REV A01

                                            I have received this laptop which was described as "does not power on or accept charge." Battery shows no sign of charging when charger is plugged in, nor does the board show any signs of life when battery is unplugged and charger is plugged in. No light from the LED at all or any other indications of activity.

                                            Board seems to have no shorts, all power rails are fine and show high resistance.

                                            When charger is plugged in, voltage is present in 3.3V rail but absent in others....

                                            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....
