    dv 172 repair?

    Mitsubishi's repairer quotes $200+ for repairing/replacing faulty board. Can anybody enlighten me about the possibility of doing the job myself or of getting spare parts (circuit board - the display itself has no faults).
    Otherwise it seems a better option to buy a new display.
    Thanks for comments/advice

          To open DV172 monitor case, it needs to

          1) remove 4 bolts keeping monitor stand.
          2) remove stand pulling for the body of the stand.
          3) then remove 5 screws from a cover.
          4) open plastic locks around the cover.
          5) open the cover.

          That's it.

                  Problem

                  This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                  Samsung UN65NU6900FXZA Stand-by light on but voltages on PS indicate TV should be on
                  by DXseekerMO
                  Hello everyone!

                  Tonight I picked up a Samsung UN65NU6900FXZA with a curious issue.

                  Symptoms:

                  1) Plug TV in to AC outlet, stand-by light illuminates briefly and goes out.
                  2) TV does not appear to turn on
                  3) Backlights do not illuminate, voltages associated with backlights on Power Supply are not present
                  4) "Power on" terminal on Power Supply has 3.26v
                  5) "A13V" terminals have 12.9v
                  6) Stand-by test jumper on Power Supply has 12.9V
                  7) Optical audio jack on Main Board illuminates
                  8) With stand-by...

                  Schenker VIA 15 PRO, PF 4NU1F V1.0, P/N: MBPPF4NU18-F310 - 36mA in stand-by
                  by FriedFred
                  Hello, everyone!
                  I have here a Schenker VIA 15 PRO, with this numbers on the board: PF 4NU1F V1.0 and P/N: MBPPF4NU18-F310 .
                  I took out the memory and the battery and the SSD.

                  So, in stand-by, only the board, takes 36mA. No power-button pressed at all, I can measure 1.8V, 3.3V, 5V. All coils present voltages except the two power rails for the CPU. The CPU is a AMD Ryzen 5 4600H.
                  After pressing the power-button, the current raises to 500mA and the two power rails for the CPU show up with 0.8V.
                  After several seconds, the fans switch-off and the board keeps powered...

                  LG OLE65C1 Stand-By issue
                  by Titus6
                  Hello everyone,

                  I bought an OLED65C1 refurbished TV back in 2022 from a shop. The TV is awesome, this is my first OLED and I really love it.

                  However I have an issue with the TV since the end of last year. I noticed when my TV is in Stand-By, sometimes the LED goes off then comes back on. When do so it seem periodical. It only goes away for 1-2 seconds, than comes back on. The TV NEVER turnes off, while it's on, so it's not overheating issue or electrical power issue.

                  I bought a service remote (MKJ39170828) and checked the menu 3. Power On/Off Status. I took...

                  Macbook Pro A1706 820-00923 no power after replacing top cover and keyboard
                  by johnbeton
                  Hello,

                  I have a A1706 with 820-00923-A board. The laptop came in with non-working keyboard. I bought a new top-cover with keyboard and transfered everything to the new topcover.
                  Since then the macbook will not charge or power-up. Before replacing top cover, I started the macbook to test, and it worked fine apart from keyboard. Then shut it down and did replacement.
                  This is what I measure so far:


                  Resistance from F7000 to ground is 123 Ohm on pin 1 and 2

                  PPBUS_G3H = 0,79v
                  PPBUS_HS_CPU = 0,79v
                  PPBUS_HS_OTH5V = 0,79v
                  PPBUS_HS_OTH3V3...
