    phillips 32AV504D power fault

    can someone please give me some advice regarding the fault with my tv.
    when you press the power button on front panel the green led lights up then the relay on powerboard clicks after 5 seconds the green led goes out and just the red led remains on.i have checked the electrolytic caps all seem ok with good esr readings.i have tried it without inverter board plugged in but the problem is the same.
    i have taken some voltage readings from top connector of power board
    these are with the cable unplugged from main av board.

    5v-------------5.16v
    5v-------------5.16v
    3.3v-----------0v
    6v-------------0v
    9v-------------0v

    i then reconnected the cable to av board and tested again.
    switch on power button on front of tv and get these voltages
    5v--------------5.07v --------relay clicks then drops to 0v
    5v--------------5,07v---------relay clicks then drops to 0v
    3.3v------------3.4v-----------relay clicks then drops to 0v
    6v---------------6.07v---------relay clicks then drops to 0v
    9v---------------8.9v-----------relay clicks then drops to 0v

    i have tested the white resistor in photo 3 out of circuit and its showing faulty.could this be the cause of the powerboard switching itself off.
    thanks in advance.

                  I have exactly the same problem? Has anyone found the cause? Has anyone solved this defect?

                      Panasonic SA-MAX770PU SMPSU board fault....
                      by Rictech
                      Hello everyone. 😀

                      As per thread title, this unit has a serious SMPSU fault. It blows F1001, which is a 10A M205 in the phase from the mains input.
                      Very first thing I tried, was simply replacing the fuse, but the replacement ceramic fuse blew immediately.

                      Looking at the schematic for this PSU, I then removed what I thought was the next likely candidate: D1001 - the HV main bridge rectifier.
                      This isolated the fault(no longer blows the main fuse), but does not point me to the actual fault.
                      There are no devices that have exploded or otherwise show signs...

                      Samsung QN75Q6FNA backlight no display, red LED blink 2x, fault in panel
                      by howardc64
                      • Prior owner tried a replacement main board. No difference.
                      • Samsung 2x red blinking standby LED = panel fault
                      • Jumpered FB_TRDY_1 (pin 1 CN1300 left. main tcon->left side buffer boards) and FB_TRDY_3 (pin 95 CN1301 right. main tcon->right side buffer boards) This allows testing individual T-Con (on main board) connection to panel on this Samsung. Found fault on left side (viewing from rear of TV)
                      • Each side has 2 buffer boards, disconnected left side flex between 2 buffer boards. Fault is on the left most board.
                      • Tape masking eventually isolated to CN1300 pin 15 (CKV4_GOA) Display

                      ESR meter came to the rescue again today with a PLC I/O card fault
                      by sam_sam_sam
                      I have been having a fun time at work with two pieces of equipment that had shorted components or shorted component cables to machine frame
                      I would check what my multi meter was telling me about how many ohms I getting with the multi meter was telling versus the ESR was telling me about weather or not it really was a short to machine ground or not

                      One note at first we thought that it might be a bad I/O card or a malfunction PLC including me as well but I thought I would try and see if removing the I/O cables would make a difference or not and this time it did make a difference...

                      Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                      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...

                      Strange fault on Lenovo ThinkPad E14 Gen. 2
                      by cazi1001
                      Hello,
                      I have a strange fault with a Lenovo ThinkPad E14 G2 (Board No. NM-D011 Rev. 1.0).

                      The first Problem, which I fixed already, was a dead TPS65944AD (USB Type-C) controller. After I fixed this fault, all functions working fine and the notebook run very well with the charger and battery.
                      On the next day, I tied to start the notebook with the battery, but nothing happened. I started with the charger and on windows, I saw, that the battery was empty. And this was nearly impossible, because the battery was charged. I disconnected the battery and found out, that the board...
