    Samsung 215TW - Bad Caps?

    Hi Badcaps users,

    I recently was given a broken Samsung 215TW that I'm about 90% sure has bad caps on the power board. When the monitor powers up, the blue power light appears, but the picture only comes up after warming up for a few minutes. When it does appear, it's super dim. After a few more minutes, it will get brighter but flicker like crazy then the picture will completely cut out entirely.

    I searched on google to see to if I could find any reason for the problem, and I stumbled upon this super helpful forum. I read the thread located here which explained a lot but I still have a few questions.

    I took out the power board and placed it in a known working Samsung 215TW. The good monitor would power on, with the blue light, but no picture. It never had any picture appear after waiting a few minutes, not sure why, but it seems that board is the issue.

    I unfortunately didn't have time to put the known working power board into the non-functioning monitor to see if it was just the board and nothing else. So for now I'm assuming it the power board and not logic board with all the input connections.

    Anyway, taking a look at the 6 brown caps, it appears that all of them are bulging. So I plan to replace them with better caps, but I'm a completely new to replacing bad capacitors. I don't know which brands would be good to replace it with. I know Digikey has a lot of selection for cheap capacitors, but it's a bit overwhelming.

    I know that I need the following caps but other that info, I'm not sure what what type, or what brand to purchase.

    1x 47uF50V
    2x 820uF25V
    3x 330uF25V
    1x 180uf450V?

    Also, I'm not sure I need to replace the larger. Can anyone give any suggestions?

    Thank you,
    JWatson

      1) Great pics. It helps a lot.

      2) Thanks for doing some research.

      3) The largest cap rarely, but not never, fails. The largest cap doesn't undergo the same stress as the other caps. Most here leave the largest cap as is.

      4) To order from digikey, do this (to pick Panasonic FM low ESR series).

      In the search field, click on in stock. Then type "820uF 25V fm" into the field. Make sure the diameter and height dimensions fit.

      Do the same for the other caps. If FM is not available, replace with FC.

      5) If you want verficiation, post your list and someone will verify.

          6) It looks like the original caps are Capxon GL. Capxon has a terrible reputation for making capacitors.

                  Yeah, that's what I've been reading on various forums. Seems like samsung has terrible Quality Control because of using cheap caps. It's too bad because the picture quality is stunning on the working 215TW. Hopefully with the replacement caps, the broken one will too

                      Post more information...

                      1) Voltage
                      2) Microfarads
                      3) Diameter in millimeters
                      4) Series (Like Capxon "GL" or Capxon KF")

                          Okay, time to update this thread!

                          So I finally got around to ordering replacement caps. I ended up taking the advice from retiredcaps and ordered my caps from Digikey and used the Panasonic caps for replacing all the Capxon caps except for the largest one. I bought the following caps:

                          Qty Part# Manufacturer Part# Unit Price Total
                          2 P12391-ND EEU-FM1E821L 0.75000 $1.50
                          3 P12386-ND EEU-FM1E331 0.51000 $1.53
                          1 P10321-ND EEU-FC1H470 0.34000 $0.34

                          I got some help from my father who had a professional soldering kit, including the oh so useful solder sucker, which made replacing the caps a breeze. It took about 20 minutes to remove and replace all the caps. Once the caps were replaced, I reassembled the monitor and now it's working great! No more flickering image

                          Thanks for the advice retiredcaps!

                              Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                              by Tynan Dill
                              I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                              Upon bringing it home and plugging it up, it showed a standby light.

                              I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                              The screen seems to blackout and stay black, but with a flashlight I can see the display.

                              With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                              Assuming...

                              Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't

                              Upgrading a Samsung ue55nu7096u with logic board from an ue55ru7105k -- good idea?
                              by ohren
                              I hope this is the right forum to post in despite not technically being a repair, but still a question of swapping boards.

                              I thought I'd explore the possibility to upgrade an existing working Samsung ue55nu7096u with the logic board (and power board if needed) of a newer model (ue55ru7105k) of the same size and appearance (and resolution). The reason being I'd like the extra inputs of that board including component in, an extra HDMI port and bluetooth. Its panel is broken so I have no use for the board otherwise.

                              The models launched in 2018 and 2019 respectively....

                              Replacement caps for Samson Resolv studio monitor 65A Amp board.
                              by black6host
                              Good day!

                              I have a Samson Resolv studio monitor that has no sound output. I've opened it up and found two caps that are bulging on what I believe to be the power supply section of the amplifier board. The board is marked Resolv 65A AMP V1.2. The caps in question are YUSCON, 2200uF, 35V, 85C temp and have markings of RA(P) and are 16mm x 25.5mm tall. I've attached the schematic and the caps in question are C5 and C6. I'm assuming they are low esr caps. I've tested both caps and they test low uF, nowhere near 2200uF.

                              I'm going to replace the caps and I'll be the first...
