    Samsung 245BW cold start problem

    Everyday morning for the last one week, when I turn on the PC, the Samsung SyncMaster 245BW display doesn't show anything, just a black screen. Then I just disconnect the power to the monitor or flip the switch in the back, the display comes back live.

    I noticed that, it happens when temperature in the room is below 75F, other times it is as normal.

    Anybody knows what is causing this?

        If you don't have a tester, you should replace all of them, or at least the ones that are leaking.

              I found two bulged Capacitors in my monitor. Both of them are 1000 uF, 10 V, 105 C.
              I have been looking to buy two capacitors to replace. I prefer Panasonic, but I can't find one or don't know where to look.

              I am not familiar with this, so the silly questions .

              1. Is this a correct part showing in this link?
              https://www.digikey.com/product-deta...4-1-ND/1662564

              It says "lead free". If there is no lead how do I solder it?
              Where can I find a Panasonic capacitor with the above specification?

              2. I saw a repair kit for Samsung 245. It comes with 15 capacitors and 3 resistors. It says, " We only use the highest quality Panasonic, Nichicon and Rubycon capacitors in our repair kits "

              I wonder if those capacitors are genuine or counterfeit. Anybody has any experience with them? Here is the link
              https://www.amazon.com/Repair-Samsun.../dp/B0067G3HAQ

              Please give me some advice regarding this.

              I don't have any idea which one to buy.

                  It means it does not contain any lead:

                    I didn't take Caps out of the board to measure and don't have the specification sheet. This power board model is BN44-00173A. I put everything back and using the same monitor now since I don't have a spare one.

                    But I took a picture of it. Please take a look at it.

                      Samsung UN55JU650DF network/streaming problem
                      by howardc64
                      Fixed a 9 year old UN55JU650 by replacing backlight. Original backlight LED was still working after 27k! hours but terrible picture of course. Few LEDs were out, 5-6 lens fell off (bright white spots) and another few popped off with slightest force. Surviving LEDs were all slightly blue so picture has a blue tint.

                      Hello
                      I have a problem with a samsung 943B, initially thinking it was a power problem i replaced the power board which is a bn44-00082e, i had a flashing of the ccfl lamps and the monitor would not start, i replaced the power board and the problem is remained, thinking they were the lamps I tested them with a ccfl lamp tester and they are all working, at this point I think it is the main board which is a BN41-01172B, my question is, before making a further purchase there is a way to turn on the lamps without the main board to exclude that the new power board is also broken? Of course without...
