    Lg 60pa5500 eax64279701

    Hello everyone!
    I got one LG plasma TV 60PA5500 with faulty Y-sus board. The tv power up when i push the power on button but screen not turn on. I check all voltages at power supply board,main board,etc and looks fine when Y-sus board is disconnected. With the Y-sus board connected the VA voltage flashing 35V to 55V. So after i checked the Y-sus board i noticed some burned parts like diodes and transistors at back side (SOT-323). I marked them at attached image.So i wanna 1st ask if any same tv owner can help me whats the transistor marking code Q504 because mine its totaly burned( i only see a "*W" mark on it), 2nd whats the mark code of Zener diode Z0501 and 3rd whats the voltage measure at 5VF pin at buffer connector because i measure 205V like SUSDN pin. If anyone can help will be very kind.

      I checked for you on the service manuals and these never have the plasma driver boards. It only talks of the main AV board. Unless there is someone on this forum that knows you are stuck.

              I understand that these plasma driver boards are used on different tv brands but where do we get the circuit diagrmas for them. I have never seen a single one for LG or Samsung. Koreans????????????

                          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...

                          Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
                          Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

                          LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
                          by Hakuu
                          Hi There,

                          This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

                          After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

                          More Details

                          Sony xbr-65x900c main board issues?
                          by jb_Bak
                          Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

                          Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
                          Power Board Connector that goes to Main board
                          CN6401
                          Pin 01 NC
                          Pin 02 NC
                          Pin 03 "BL_ON": 0V
                          Pin 04 "N/C"
                          Pin 05 "STBY 3.3V": 3.5V
                          Pin 06 "GND": N/C
                          Pin 07 "AC_OFF"...

                          Panasonic TC-P54VT25 No image. A or D board?
                          by canadaboy25
                          I have a Panasonic TC-P54VT25 that will power on and prime the display but there is no image at all.

                          The panel is primed as there is a slight glow from the entire panel. This means the problem should be logic related. The service manual also confirms this and recommends replacing the A or the D board.

                          I have tried to get the TV to display the test sequence but I have been unable to and I don't even know if this TV has a test sequence or not. I tried following tom66's instructions in post #3 on this thread https://www.badcaps.net/forum/showthread.php?t=26790. There was...
