    Emerson LC401EM3F ps replaced, tv comes on, inputs dont work????

    So I replaced a power supply on this tv and it fired right up, so I put the cover back on hooked it up and couldnt get any of the inputs to work. I can go to the menu, picture is crystal clear and even though the inputs are on two different boards none of them work except for the USB input. It is the weirdest thing. I tried another main board and it does the exact same thing. All I could think of is possibly one of the ribbon cables got messed up. I'm trying to find replacements now.

    Thanks in advance,
    Jonathan

      I'd try cleaning the ribbon sockets and ribbon connectors with 70 or 90% rubbing alcohol and a tooth brush. Make sure ribbons are fully seated probably.

        It was the digital board. Works like a top now.

          MSI MS-16W1 no power, EC replaced by other.
          by MicroSMD Lab
          Hi, I'm working on a MSI laptop, Motherboard number MS-16W11, GF-65 Thin 10SDR-459US. Went to another shop because the screen was flickering, but it was working well on an external monitor. The LCD was ordered and the laptop was returned to the customer and it no longer worked. It was then sent to another tech (by the shop who ordered the LCD) and the EC (ENE KB9028Q) was replaced with a donor from another MSI board with different board number and no programming was done. It looks like work was done on PU6 (TPS51225) as well as one of the GPU mosfets was burnt (I removed all three GPU mosfets)....

          Asus FX505DD REV 2.0 no power after someone replaced the cmos battery with a screwdriver.
          by thesame
          I have a dead FX505D, motherboard FX505DD REV 2.0 , the owner replaced the cmos using a screwdriver and he touched something on the board, since then the laptop its not starting, i have managed to see that U8800 (BQ24780SRUYR) charging IC is getting hot under a thermal camera , i have desoldered it but the laptop still doesn't power on, i also have no voltage at power connector on the board. I also replaced the U8800 but still no power. What should i check next?

          HP Probook 640 G5 - replaced blown components, getting power led, fan full, 5-flashes on CAPS Lock and NUM lock, black screen
          by zlr8r
          Hey guys, bit stumped with this laptop after replacing 2 blown components i.e., MP86493, MP2979A.

          To begin with, this laptop was dead-dead.

          Now with replaced (visibly) blown components, i do get some progress; after connecting battery or main cable;
          • am getting white power led
          • 5-long-flashes on CAPS Lock and NUM lock
          • then, fan full speed
          • CPU heats up some (smaller die PCH, does not)
          • always constant black screen no matter what's tried
          • no USB recognition
          • no HDMI output
          this is as far as I can get with it and not sure where to inspect next ?

          I tried...

          HP Victus 15-fb (DAG3PRMB8D0) – ISL88739B replaced, now PROCHOT EXT active and slow CPU (0.4 GHz)
          by adelfr2009
          Hello .
          I have an HP Victus 15-fb laptop with the DAG3PRMB8D0 motherboard, Ryzen 7 7535HS CPU, and RTX 2050 GPU. I had a short on the 19 V line, and I was forced to replace the following components:

          1- 2 nmos near dc jack connector
          2- ic charger (88739b) + small resistor between CSIN pin and sense resistor output
          3- i changed also a 1 dual mosfet in VRM

          After replacing the VRM MOSFETs and the charger IC, the laptop works and the CPU survived 🙏

          However, now I have a problem: the laptop is very slow, running only at 0.4 GHz.
          After...

          ViewSonic Pf815 (branded as P225f) Horizontal Deflection Issues - Running out of Ideas
          by rstrube
          Note: apologies I initially posted this request for help in the wrong forum! I am reposting it here and will take down the original posting.

          Hi Everyone,

          I've been working on repairing this beautiful CRT monitor off and on for the past several months and I'm really at a loss for what might be causing the problem.

          Unlike other common Horizontal Deflection issues which result in a steady vertical line, when I turn the monitor on, there is a pulsing (somewhat segmented) vertical line. I've attached a photo that shows the issue (difficult to capture without video)....
