One of my Acer AL1706b monitors finally died recently. After doing some research here and elsewhere on the internet I'm not sure how to proceed from here.
After checking the T2A/250VAC fuse I moved onto the 82uF 450V capacitor (170V). Then the wires heading from the power board (ILPI-003 REV:C - 2006.06.19) to the logic board.
From bottom to top the wires are:
1.VCC5V - 5V
2.VCC5V - 5V
3.GND - 0V
4.BRIGHTNESS - 0V
5.ON/OFF - 0V
6.GND - 0V
Assuming that's what they should be I moved onto the logic board. After reading PlainBill's Post in a different thread I took down the following readings:
U101:
1. 0V
2. 1.27V
3. 5V
U102:
1. 0V
2. 1.85V
3. 5.2V
After consulting page 5 (or 44) of AL1706x.pdf I was lead to believe these are not the correct voltages for these regulators. Could it be as simple as replacing these two regulators?
I got excited that perhaps I would just be able to short or remove U406 (Reset Controller) however that component would not appear to be present on my board.
I'm not sure how to proceed from here but I'm sure the vast knowledge of the internet will point me in the next direction! Thanks in advance for any help or guidance anyone can offer me. Also, sorry for the blurry pictures, my camera is very sad. I can have my friend take far better pictures if necessary.
