Samsung RV520 wont turn on, won’t power on, no display, black screen problems

Laptop Samsung RV520 won’t turn on, won’t power on, there is no display, just a black screen. This is a general diagnostic and repair steps to fix those problems.

Troubleshooting laptop Samsung RV520 won’t boot, won’t power on, no display just black screen

When you push on the Power Button the Power led lights ON or NOT, your Samsung RV520 won’t start up, and there is no display just a black screen. Possible problem and the fixes steps:

Battery has no charge left + AC adapter failed; you press the power button on laptop Samsung RV520 nothing happens, laptop won’t turns on and there is no display, the battery has no charge left, the motherboard doesn’t receive any power, laptop cannot turn on. You plug in the AC adapter but that doesn’t help, your laptop Samsung RV520 still won’t power on, there is a chance you have failed AC adapter. In this case try with another charger or check AC adapter with a Multimeter. If it’s dead, replaced with a new one.

Power circuit in wrong state or Over volt protection trips; you press the power button but nothing happens, laptop Samsung RV520 won’t turns on and there is no display just a black screen, your laptop has static electric charge made power circuit in wrong state. Unplug AC adapter, take out the battery and hold down power button for 30 seconds, the static charge will dissipate. Plug in the AC Adapter and turn on your laptop Samsung RV520. This should restore the system to normal operating mode.

Hardware failure; the laptop powers on, but there is no display just black screen with Power led lights ON or your laptop Samsung RV520 stock on logo or restart. In this case, it’s possible one of the Hardware failed. You can try to disassemble the laptop to bare minimum and try to reseat the hardware one by one and power on the laptop every time you reseat a hardware, to know the failed one, replace the faulty hardware.

Screen faulty or bad video cable connection; laptop Samsung RV520 turns on, but screen is black, with Power led lights ON. Test the laptop with an external monitor connected to the HDMI port, VGA port, press the appropriate key to switch to it. If the external monitor works fine and load the operation system, most likely you have a faulty screen or bad video cable connection. Check them and replace the faulty one.

BIOS failed; Laptop Samsung RV520 won’t turn on at all, if the voltage 19V, 3.3V, 5V OK  and electronics components on the motherboard are good, there is chance you have failed BIOS. There is a signal test confirmation on EC/SIO pin name RSMRST# . This pin must available 3.3V(tolerance 10%) than Bios Confirmed OK. If the test failed reprogram or replace the BIOS chip.

Laptop Power System has problem: Laptop Samsung RV520 won’t turn on at all, probably some electronics components or chipset on the motherboard failed;  Disassemble the laptop and take out the motherboard. Ceck No burnt marks visible on the mainboard. Check chepset temperature (CPU,  GPU, Power-Supply IC …). Check power jack. Check motherboard receives 19V. with a Multimeter measure voltages on coils, check for any components shorted to ground.  checked 3.3v/5v is up and running?

If you  have 3VALW And 5VALW at coil. 3VALW should go to sio and from there you should get 3v at power button. Check SIO for corrosion,shorting or any componenets which looks suspect. Check 3 & 5v SUS voltage.

Will need an electronic boardview or Schematic Diagram for Laptop Samsung RV520. The failed electronic component has to be replaced.

Note: (In the comments we will be updated electronics components failure).

Motherboard dead; The Samsung RV520 motherboard has to be replaced.

    HI this machine is dropped and after this black screen . on LVDS i have 3,3v only on 3 pins .
    the problem is i have only schematic but i need board view to trace components .

    model BA41-01610A SCALA2_R

    Goodmorning friends of the forum. This laptop has isegent defects:
    When I give power on it does not react,
    I have to make several attempts until that main power up.
    I have no image on both lcd and vga screens.
    I noticed that it warms up the pch.
    The tensions seem to be there in the coils except that of the cpu (cpu_core) that are missing.
    I tried to exchange the cpu but nothing.
    I tried to reprogram the bios with dumps found on the net but nothing to do.
    I did a reflow on the NVIDIA bga but nothing.
    Also changed the ram but nothing
    The resistance on coils with inserted cpu and 12 Ohm, I think it is correct.
    The thing that leaves me perpplesso and that pch warms up a lot and does not seem normal.
    Since I do not have printing on the board it is difficult to follow the diagram but I have measured near the pch of the capacitors and I find a resistance of 3ohm which seems to me low.
    I checked on U511 at pin 7 and I find 3V.
    Thank you
