Hi there.
I'm not native English speaking person, so if something is not clear please let me know and I will try to explain it more detailed.
Power supply is 220V 50Hz.
I have Acer 1916N monitor, which when turned on it lights, shows the ACER logo, but the fade in effect is shown like frames which the normal eye could catch. And right after the logo is shown, the monitor goes blank (total darkness), nothing is visible on the background under external light (so I think it's not background light issue). However, the power LED is always ON and do not switch OFF, neither blinking, or switch to orange (when sleep).
I read the other posts for similar monitors in this class AL1916, but nothing of the listed things help me.
I don't see any bad caps, or other burn in elements. However, the main power board has brown areas due to hearing or something like that, and the logic board has one regulator which seems to be heating, but when I measure it shows good voltages.
Also, the big PET capacitor is in good looking shape (don't be mistaken by the labels .. they are printed in non-perfect line .. the capacitor has perfect cylindric form) and under power shows 310V, but on the positive lead it has small drop of something like dry electrolyte which I push and if falls.
Under power, the voltage on the cable between power and logic board shows the same values as listed on the power board (next to the connector)..
So between black and red wires I have 4.95V/4.96V as listed on the board (5V).
The attached images are both used in this monitor.
Any ideas what could be wrong and did somebody has been working on similar issue?
Thanks!
