    VP50HDTV10A YSUS Board Help

    First time poster, long time reader, and may I say I have learned a bit from you all.
    But now I have an issue that I am unable to find the answer to on here so here we go.I am getting open result on R54 and R55, What are the replacement specifications for these resistors/fuses?

    Thanks in advance

      I believe they are 5 Ohm 5W x2. Check your IPM module. Its probably shorted.
      Did I leave the soldering iron on?

              Voltmeter on Ohm setting black lead on ground red lead on every Other pin on the IPM module besides ground if you have a short it will show up. of course there are two modules you need to check both

                  OK here is what I did and what I got. Grounded to mounting hole and verified by touching grnd pins. Tested on each side of both IPM's all open no shorts. But In the picture attached hopefully you can see the red circle around 5 pins those sounded off like the grnd next to them is that correct? Are my IPM's ok and I just need to replace the fuses?

                      Is this the resistors I need?

                          I just replaced resistors on R54 and R55 on the Y-sustain of the same TV. If the colored bands are brown, black, black, gold it is a 2watt 10 ohm 5% tolerance flame proof resistor.
                          I purchased From digi-key part #RSMF2JT10R0CT-ND
                          R265 was blown on my board as well.

                              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...

                              TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
                              by howardc64
                              All left and right refers to looking from rear of TV (or looking from front with TV upside down)
                              • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
                              • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

                              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

                              TV Model - LG OLED77G1PUA

                              Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...

                              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"...
