Issue: when switch ON, the screen blink very quick showing "Acer", and black screen, and the power LED also blink from orange to blue.
Open up the monitor
- No bad cap
- With connectors remove from logic board and CCFL, the power board has stable voltage of 5V and 14v
- On the back of PSB, the U501 & U502 Mosfet (9962GH) no short (measured the leads desoldered from board)
- IC501 i believe is inverter controller, part (MPS 0805, MP1008ES). Can't find the datasheet online
- Inverter transformer: secondary leads 517 ohms for both transformer
I am thinking of opening up the CCFL backlight to see if the problems lie in there.
Any advice before i proceed further ?
thanks
