Re: Acer 1916N goes blank after 2-3 seconds
Good suggestion ...
In the moment I have an WinXP running under recovery mode to check the HDD for bad sectors. The other monitor is like in DOS mode, so I just plug the problem monitor to the PC and stay ON for much longer (I don't count the seconds, because I try to go faster to the OSD), but for sure it was 30 seconds showing the DOS mode.
I found the reset option into the OSD and run it, after that, the monitor went blank again. I turn it off (from the power too) and then turn it on, but now after the ACER logo it goes...Leave a comment:

Re: Acer 1916N goes blank after 2-3 seconds
Hi guys
No, when I open the monitor it was like this, nothing is removed.
Ok, the diode mounted on heatsink is D920. The middle pin of that diode shows 14.65V.
The other one (D922), shows on the cathode (white line) 4,9V.
Both voltages are measured against the GND1 ground. This is the one on top of the connector (the nearest one).
Hope that helps. I'm still waiting for any other ideas, because I can't think of anything else....Leave a comment:

Anyone .. anything? I really have no ideas and the elements I measure don't seems to have any problems

No, I mean that there is no cable going out of the connector
In the pictures of the first post you can see that not all pins of the connector has cables attached

Re: Acer 1916N goes blank after 2-3 seconds
Hi selldoor,
Well, the PC was running before I test the monitor, so wasn't booting at the moment, but was fully loaded. I check the resolution and the frequency on an old CRT brand CTX monitor and it was 1024x768 @ 60Hz. Then I just switch the cables between both monitors. And when the monitor shows the windows screen for a second, just before to show the "Input not Supported" was showing the same resolution as on the CTX monitor.
Yes, I read the two seconds to black topic. The instructions...Leave a comment:

Re: Acer 1916N goes blank after 2-3 seconds
Yea, but I check that and it was in normal ...
1024x768 at 60Hz
This should be supported by the monitor for sure
Sorry that I forget to mention that.Leave a comment:

OK, the BIG capacitor is replaced, but the problem stay the same.
Same frames during the logo fade-in ... and when the monitor was off for longer time, actually I get a windows desktop after the Acer logo.
However, just before it went blank again, it pop-up a message box saying "Signal not Supported".
Any more ideas?

Acer 1916N goes blank after 2-3 seconds
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,... -
Re: LG Flatron L17NT-A no power
Hi guys.
Yes, I know the value it should have at the output. However, I have to desolder this component to test it, but I don't have the right equipment to do it For this one I may go to some electronic service to do this test for me.
I try this case (not connected to the LCD panel), but the voltages still drop off. So, with or without the LCD panel the voltages continue to drop.
About the resistance on pin6 against the ground, I hope I will have a time to test it tomorrow....Leave a comment:

Re: LG Flatron L17NT-A no power
Hi all.
This is my first post here, but I'm very happy about the things I found in this thread.
I have LG Flatron L19175 which is dead. No indications on the panel, no leds flashing, no backlight, just nothing.
I do the measures described in this thread and think my power board is OK.
Here are some numbers:
Main voltage is 230V
C101 - 313 Vdc
U101 (FAN 7601) - between pin1 and pin5 - 295Vdc
Then I measure the 11 pin connector against PG2.
On pins 6 and 7 I get 4,91Vdc...Leave a comment:
