    Re: Phillips 50PF7521d/12 Wont turn on

    Yes i do want to replace them just cant seem to find the right ones? maybe im looking at the wrong ones. Could you possibly point towards the correct caps if poss? Those 2 are roughly 25x16ml 63v 470uf and 130 degree.

      Sure about 63V 470uF?
      Here is replacement:

          You probably don't. The original capacitors were of poor design and ran hot, so required a higher operating temperature. Generally, 105°C is fine. Acquiring 130°C capacitors is next to impossible. I'm guessing the caps are Samwha? There is a well known manufacturing defect with a batch of them around 2007~2010.

            Your right they are sanwah! And that is probably why i cant find the 130 degree ones if as you say its impossible to get them now lol. So what about heat wise if i was going to swap them for 105'c will they still be able to cope? these sanwahs are bigger then normal caps too.

              If the heat inside is hot enough to boil water, I think you have really bad problem in the TV.

                        yeah they are like half the size of the gold caps that are in the pic (The samwha ones) but are 105c not the 130c

                          What is the brand/manufacturer and series (usually a letter code e.g. FC, FM) of the capacitor?

                            Panasonic FC series 16x20mm EEUFC1J471 - part number. Decided to go with these as ive heard good things about them.

                                  Hello, i have some issues with my laptop Lenovo Y700-17ISK (motherboard BY511 NM-A541), it started when i turn on the laptop, but the lcd wont turn on, i then connected it via hdmi to tv and screen was ok. So i thought maybe lcd stripe is faulty, i removed the bottom cover, disconnected main battery, reset the cmos by disconnecting battery for 1 min, then slighty move the lcd stripe. Conncted power supply and tuned on my laptop, the lcd turn on, it started to load os, then it turn off, after a second it turn on, then after like 3 seconds turn off again, and so on. Removed power supply, waited...

                                  Asus X453MA won't turn on and green led light blinking
                                  by jxrepman
                                  Hi there,

                                  I have this ASUS X453MA Laptop that's not turning on. When I plug in the charger, the green light just keeps on blinking and pressing the power button does nothing.

                                  I have checked the charger and it is giving 19+ V

                                  I have disconnected the battery and pressed power button for 30 seconds.

                                  I tried another RAM stick.

                                  Tried disconnecting the keyboard and touchpad.

                                  Tried disconnecting the HDD and the wifi adapter.

                                  The problem persists.

                                  Hope you could help me out on this one. Thank you.

                                  Hello, Badcaps is my last resort. I am the first owner of the monitor. I reached almost every repair store in my area, but no one even wanted to hear about troubleshooting an old CRT monitor. At this point, I have been trying to figure it out by myself, but I have no idea where to start or look for.

                                  I wish to know how to think and locate a failing component. I will put all my efforts to learn and contribute.
