    p50hdtv10a z-sustain question

    I have a p50hdtv10a in the shop, been sick and these meds, got my mind ,,,, well say unclear. Question is , got sound and a faint picture, had a Burnt psb, ,replaced with a spare and replaced the z and buffers, now just a faint pic and sound stays on so a bad z-sustain is likely ?
    Thanks
    Mike

      If you mean you replaced the "Y" then yes sounds like the z board is failed but without pics...

          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...
