    I know you've said that before. I trust you.
    I just don't understand it. Lol.
    I trust Einstein was right about his theories but I don't get them. Lol

    By the way, thanks for your help.

        Just out of curiosity, has anyone ever come a cross just one bad led?
        Would it be possible to bypass one? Would you notice it on the display?

            You can use 5 1N4007 Diodes to simulate the Vf of the White LED.

                    I just cracked one of these open....same problem...took a while but once I got the white plastic cover that's over the leds I found one string unplugged....put it back together and it works...think I messed it up though. ..one line of pixels is blue ...

                        Emerson LF501EM5F, turns on, logo appears, shuts off, the perfect storm?
                        by DXseekerMO
                        Earlier this week I got an Emerson LF501EM5F that turns on, the logo comes up, a menu and the channel box come on and it immediately shuts down a split second later.

                        This was bought new and went in a Laundromat. From there it was on from 7AM to 10PM every day.

                        So why is this the perfect storm? A month ago I got an Emerson LF501EM4 and an EM4A, both will not turn on. The EM4A was struck by lightning and has a serial of DS1 The EM5F has a serial of DS5. The EM4 has a DS4 serial and the chirping transformer problem with a replaced power supply.

                        The info...

                        (SOLVED) - Emerson lf501em5f - Turns on, shows logo, then shuts off.
                        by JDC
                        Issue: Emerson lf501em5f turns on, shows logo, then briefly shows what input it is on, then goes black.

                        Solution: Bad LEDs. In my case, there were 2. This repair may not be worth it unless you're doing it for yourself. I'm personally not a fan of Emerson TVs nowadays.

                        PS4 pro PSU (ADP-300FR) shuts down when turning on 12V
                        by Norrecito
                        Hello all,

                        I would like to ask for your help to troubleshoot a faulty PS4 pro power supply (ADP-300FR).

                        A couple of weeks ago, I've picked up a PS4 Pro (CUH-7216B) from one of the local flee markets. According to the seller, it has a "no power" issue and the PSU is most likely faulty. Based on the cracks on the housing, it was probably dropped.

                        Tried it at home and sure enough, it had a "no power" issue. (Pressing either the power or eject buttons had no effect).

                        I took out the PSU and opened it. Immediately noticed...
