Re: Acer 1916w monitor

DAP8A is a NCP1203D6

I assume that in the full part code is NCP1203D60R2G,the '60' being the internal 60Khz ???? I have a DAP8( no letter A after it) would it be logical to assume that it could be the 100KHZ version NCP1203D100R2G.
I am trying to repair a Power Supply from a Viewsonic VX800. I have replaced the DAP8 with a NCP 60Khz version, and although that has the Supply now working, the PSU Output pulses constantly when any load is placed on it,and I am thinking the problem is because of the frequency difference between the DAP8 and the 8A ???

Re: Acer 1916w monitor

If it helps the DAP8A is made by ON semiconductor, and there sub package part number is DAP008D
The full number is DAP008DR2G
