Re: Acer AL1916W Ab Monitor, DAC-19M008 - No Backlight, Recapped, Can see with Flashl


Update!
I've replace the OZ9910GN and something news appens. Now, while powering on, it flash for a brief moment, then goes black.
If I leave it powered on for some minute and try switch it off-on, sometimes it starts and works fine.
What can I check now?
Thanks

Addendum: With oscilloscope, I checked pin5 oscillator. At power on or after Screen Wakeup, it starts from 0V, then start to oscillate at about 3 Khz for few milliseconds ( about 20) then goes fixed to 5V.
Tomorrow I'go to buy a OZ9910....

Hi all,

I've read all previous post and none helped me to fix the problem.
My situation is the following:

- Voltage on pin 15 and 16 follow as described on [url]https://www.badcaps.net/forum/showpost.php?p=118789&postcount=4[/url]
- Voltage on pin 8 follow the Enable signal.
- Voltage on pin 5 and 12 is 5 V for some seconds...
