Help with eMachines E19T5W LCD

[Howie]

This monitor was gave to me and wouldn't power on because of bad caps. I replaced all the caps on the power supply and now the monitor will power on and display perfect for a few seconds, but has an issue like its losing signal feed from PC once Windows loads. I'm using the VGA input because my PC doesn't have DVI outputs.

It will display correctly till Windows loads the Welcome screen and then it will go black a second or two, then display the test screen "no signal" icon, then go black again a few seconds, then display the Welcome screen with the "VGA Input" icon. It will repeat this over and over. While its doing this the power button and menu buttons are non responsive.

Anyone have a clue?

You might have to recap the control board as well

In another thread, this was due to the computer being set to a refresh rate the monitor couldn't handle. Some LCDs accept 75Hz, most want only 60Hz. Also check that the resolution isn't higher than the monitor can handle.

Thanks for both replies. I 1st tried to boot into bios and let it sit there about 20 seconds and it started to repeat the issue so that eliminated a Windows setting. I took it back apart and recapped the control board as suggested and it now has been on the desktop for 15 minutes without any issues and the menu controls work great so that was the problem.

The control board had about 12 tiny caps made by Teapo . They ranged in value from 10uf, 22uf, 100uf and one 220uf.

Thanks for the help, and after a complete PSU and control board recap, monitor is now working.
