Hello,
Ive read a lot of about possible issues with AL1916W, but I can still find out the right source of the issue.
Monitor after power up flash up for 1 second, green LED flash up for one second and thats all.
My AL1916W had:
1) Bulged caps CE108, CE103, C204, all 220uF/25V on inverter board. Replaced.
- still same issue
2) The fuse F200 was blown out. Replaced.
- The inverter board start work every second and shut down and again, again...
3)Q206 AP40T03GP was blown. replaced with IRF540N. Its only for test, because...

Re: LG W2241S white screen symptom
Ive attached images of PWR, logic and panel board. Caps on logic board looks ok. Ive tried change PWR PCB+logic PCB+cable from similar type LG monitor, where is no white screen symptom. Without success.
It looks as panel board problem, but where or how to find it?
