Re: ViewSonic VA1912wb

I have a simple suggestion. I believe this is about the third or fourth request you have made for this information, and I'm getting a little bored with it. Instead of spamming the forum with requests for a list of stock numbers, how about YOU doing a little work?

Make a list of the electrolytic capacitors on the power supply. For each one, show the capacity, voltage, and the diameter. Also show the height of the tallest capacitor.

Then go to this post, follow the directions, and make up your own list of appropriate replacements.

Now, if you are properly apologetic, and you post the initial list and your proposed replacements, someone may confirm your selected replacements are correct.
