I-INC IF281d Flashing on and off

[matt230]

I have an I-INC IF281d Monitor and am having an issue where for the first few minutes when i turn it on the screen flashes on and off and eventually turns on and is fine. Here is a youtube video of someone elses monitor doing the same thing as mine. http://www.youtube.com/watch?v=1eVEJimknzk Any idea what the problem could be?

Did you open it up and do any inspection yet? We need to see good clear pictures of the boards, please use file attachment function upload the pictures, do not post the pictures in line.

Sound like bad caps, but like the man says, open it up and post some photos.

Your mainboard appears to be the same one used on the hanns-g hg281d. Caps C80 and C83 are a known problem on this board for drying out.

You need to check the voltages on the two 3-pin regulators on the bottom right of the board as shown in your pictures, it does look similar to hanns-g hg281d main board.
You can also try setting the pc video resolution to lowest setting to see if the screen will stay on.

You figure out which caps need to be replaced, mine is doing the same thing.

I had a similar problem and replaced the caps you have circled and it fixed the problem in my Hg281D and my If281D.

Thank you!

I know this is really late, but I just wanted to thank you for your help on this. I was able to fix it thanks to you guys. Your help was appreciated very much.

Just found this thread. Could I just replace the board with the hanns-g instead of trying to replace the capacitors??
