Acer Aspire V5 571P 6499 power on but no display or no access to BIOS

[ithe]

Hi,
I am using this Acer Aspire V5 571P 6499 laptop for a long time. Laptop does powers on, but no display after properly shutdown while in its last working condition.
Laptop model - Acer Aspire V5 571P 6499
MoBo - Husk MB 11309-4M 48.4TU05.04M
HW config. i5, 4 GB RAM,250GB SSD, Windows 10 OS


status when laptop turned on
no display no logo no BIOS access
status - power led on, charging led (when power adaptor connected), led on power switch glow when power is on.
fan spins and stops for a minute and again start spinning.
keyboard caps led doesn't turn on or off.
tried few things at first.
RAM - reseated. also seated on second slot.
connected to external monitor still no sign.
tried to turn on without SSD,WIFI,with only battery, withonly power adaptor, without keyboard
by observation - at one spot on laptop MoBo seems very hot only if laptop power is turned on, IC "G11333 01 YK9 also marked as SLJ8C" something is short circuited. how to proceed further to fix this ?

Thanks

SLJ8C is PCH and its supposed to be warm when turned on.I suggest a couple of steps
01.Measure voltage on all coils after turning on.
02.Look for corrossion on the whole mb.
03.Flash clean me bios
04.Dramrst# status?
