      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.

                  What happens if you hit the power button?

                            by Mark D
                            The TV is a Samsung UN65JU67ODFXZA Version TD01. I replaced the power source board and the TV is now working, but I decided to try and troubleshoot the old board to fix at the component level. Trying to get a schematic and a parts list has proven to be an issue. Trying on my own, I can't tell you how many times my Norton security has flagged sites as "malicious". I ordered a service manual from ServiceManuals.net, paid $16.99 and got 66 pages of everything BUT schematics and component parts list! Can anyone steer me in the right direction? Some of the surface mounted component parts...

                            This is a list of compatible laptop motherboard information that I have been collecting for some time.
                            And it's still ongoing.
                            Every time I come across information that a board is compatible with another, I write it down.
                            Anyone who wants to, can continue to expand the list.
                            Packed in the rar, is an excel table that has additional information.

                            Hi, Badcaps.

                            I am troubleshooting a monitor
                            Viewsonic VX2718-PC-mhd.

                            by lostone
                            Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.

                            First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
                            When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected...
