    Re: Vizio XVT3D474SV Completely Dead

    Did you make sure to reconnect the IR sensor board to the main board after replacing it? its usually a small connector or small ribbon and could easily have been forgotten.

        I did, and went back into it and removed and reattached again but nothing.

            when you purchased your new main board did all the numbers match up? also have you tried to test your remote control handset? or try a universal remote if you have one handy.
            Im wondering if its possible this mainboard is used in another make of tv and the remote code etc is diffrent?

                The numbers are the same. Not sure how to test the remote handset.

                    There are some guides on youtube you can sometimes use a camera phone to test if its transmitting etc.

                        Just took my Time Warner remote handset and programmed it, and it worked. Must have something wrong with the Vizio factory remote

                            I tried the phone camera but did not see anything. Must be bad.

                                yes i just tried mine on my camera phone it shows a redish colour dot on the screen when working ok so yes maybe strip the remote and check for broken solder joints ive repaired a few the led just needed resoldering.

                                    I will try, but this one has the slide out key board on the bottom.

                                            Yes, and they're pricey!

                                                Out of frustration, took the remote apart and found the ribbon cable broken. Can you find ribbon cable for repairs such as this?

                                                    Hi, I disassemble my laptop to replace the speakers, to access them, you have to remove everything including the heat sink and fan, unscrew the motherboard, lift it up a bit to access the speaker wire.
                                                    that was not the first time I dissasemble it, i did replace the same speaker a few year ago and I repaste it last year, so I had nothing to worry about. but when I put everything back together, its completely dead.

                                                    After a bit of investigating, i found one pin of the status led ribbon cable that was unglued from the cable and bend touching another pin, I bend it back at his place...

                                                    by Iain P
                                                    Hi everybody!

                                                    I've got a Vizio E65-F0 smart tv that is good and dead. It shows no signs of life when I press the power button on the back. The power LED in the lower right corner doesn't light, there is no backlight and no picture.

                                                    So I took the back off and started poking around figuring one or more of the caps had dried out. My esr meter says all the caps on the power supply board and the mainboard are less than 1 ohm.

                                                    I decided to check the voltages coming off the power supply they are as follows:

                                                    connector CN201
                                                    pin 1 (18vsb1)...

                                                    Hello Gurus,

                                                    I got a ThinkPad T480s. It was running fine but suddenly started random shut down. When it turned off, I had to push the reset pin to bring it back to life. But it got aggressively worse and became completely dead. No charging light, no life.

                                                    I did some initial diagnostics with just the board (no battery, nothing attached, and no CMOS battery as well)

                                                    Initial testing of the coil resistance seems to indicate no dead short. The only low resistance I measured was at PL701. It reads 38 ohms.
                                                    charger gave - 20V - ok

                                                    Completely dead MSI z490 tomahawk

                                                    Trying to troubleshoot MSI z490 tomahawk board and would appreciate your help. The board is completely dead and shows no activity when the power button is pressed.

                                                    I have tried to look at the Superio, the PSIN signal seems to be correct (goes from 3.3V to 0 on button press) but the voltage on PSOUT pin is quite low. I

                                                    t is only 0.8V which seems to be incorrect but goes to 0 when the button is pressed.

                                                    Can you please let me know if this is indeed incorrect and what else should I look at next?

                                                    Hello.
                                                    I received a T14s Gen1 ( NM-C891 motherboard ) that is completely dead, no indication of life at all.
                                                    I tried hard reset without RTC battery and short both pins of it for 1 minute but no luck.
                                                    Since it's type C connector i have no idea what to measure or where to inject voltage, so any advice are welcomed
                                                    Thank you in advance!
