      The max resolution is 2000x2000 and probably around 2MB for the JPG file size.

      Some proper punctuation to break up your sentences so we can understand what you are saying without having to read it 3 times is also likely to get you some help. This isn't twitter.

        When posting pictures, use "Manage Attatchments" on the post page.

            Assuming you have a meter, check for shorted components. First check from gound to the load side of the fuse. If it is grounded, then check the bridge rectifier and go from there. By the way, that is the black component with four leads in the first picture - bottom left corner

                1) In pic

                https://www.badcaps.net/forum/attach...0&d=1305477971

                you have a bloated cap.

                2) In pic

                https://www.badcaps.net/forum/attach...9&d=1305477948

                the upper right one looks bloated too.

                3) At MINIMUM, you will have to replace both. Since 2 are bloated, most here will probably recommend that you replace all the electrolytic caps with low ESR quality brand name caps.

                4) For pictures, this is an example of what we want.

                https://www.badcaps.net/forum/showpo...94&postcount=1

                We want one clear shot of all the boards so we can see the relationship between each board. Then we want each board close up, but we want to see the entire board (not cropped).

                      As mentioned, Replaced the two bulged caps (the domed ones), then try again.

                      For best results, replace ALL caps with good quality ones

                                Hi,
                                I've been living in the same apartment for about 5 years now, and moved into it with my old Samsung plasma TV (PS51F5500).
                                Ever since we've moved in, we would sometimes see strange power-cycling behavior. For example:
                                • TV would randomly turn off then back on.
                                • TV would turn off and the LED light would blink for a while (over a minute sometimes) until eventually it went back to a regular off state and could be turned on
                                • Sometimes it would require disconnecting the mains cord from the TV, waiting several minutes, then putting it back in and turning the TV back on. This had limited
                                ...
