    Re: Cap exploded...help required. Philips LCD 42PFL5404H/05

    I've recently had help from budm my self, same type of cap and same problem, the way I confirmed it was by plenty of research on the net and a simple look over the power board to see if this very cap had been used else where, his suggestion was indeed confirmed by the above two methods.

    For what it's worth I had a fuse and an electrolytic cap that also needed changing so make sure nothing else has blown.

      I would go with higher voltage:

      But wait awhile to see if some one has the same board as yours first.

        Thanks lads, i dont think there is a corner of the net i havent searched, the cap isnt used anywhere else on the board. They sell the boards on ebay and ive even emailed the seller and asked what the values are! I doubt he'll reply!
        I obviously dont want any fire hazards from incorrect components so its a waiting game i suppose

          The first tv I worked on would not power on. Not knowing anything about tvs at the time I took the cover off and plugged it in after looking for visual damage. After trying to turn it on a couple times I blew a hole through the varistor. It looked just like your cap there. I haven't been this lucky since with that sort of thing but After I replaced it the tv works fine and has worked for the last year and a half.

            Also, I have a 32PFL power supply at the house right now. I haven't read enough into your post to see what you're trying to figure out though. Do you need a part number?

              Hey Ashroyer, thanks for the post. I'm trying to find out the values of the component blown so I can order and replace it. It was damaged so the values are illegible. I have a 42pfl so I'm unsure as to whether your board and mine are similar. The location of the cap is c502

                ok. I will try to look at the board tonight after work or tomorrow. Maybe we'll get lucky.

                    There is no C502 on the board I have. Can you send me a pic of the board where it would be. Also give me the number of the component. I know when I replaced the varistor I couldn't find an exact I had to get something close as I could. Maybe with a cap go bigger to be safe. But lets see first.

                        His blown component is the high voltage snubber cap for the PFC MOSFET, not Varistor.

                          I bought a new cap from ebay, havent installed it yet but ive attached pics of the specs. It is however a bit smaller and thinner.
                          I'm wondering now what risks will come into play if it is the wrong cap. I've searched the net but cant find any info on my board so it'll have to be trial and error

                            The spec matches the one from Mouser, hope it is not fake.

                                So I soldered the new cap in, connected everything back up and the tv powered up as normal. Happy days, I'll monitor it for a bit just for peace of mind. Cheers lads

                                    No worries, I presume it was the right cap after all and it's not under stress? As I said I'll keep an eye on it, switch it off after use etc

                                      by rakonja
                                      Hello everyone! I am the owner of a Philips 42PFL7008k/12 TV! It served me well all the years. Sometimes it used to get "stuck", after which I used to disconnect it from the voltage, hold the power button on the device for about 30 seconds, and after turning it on again, it worked like new!Only once it threw something like no software!Now it happened that it won't turn on anymore, the red LED blinks twice!Do you have any suggestions? They are probably not cost effective to repair, but I am sorry to get rid of it, it has served me well and looks like new!The only downside is the slow...

                                      Philips 32PFL4901/F8 BA4GF0F0102 2 Not getting standby led

                                      Hello, guys!

                                      The same 32" Philips TV I was having video issues, but now I don't have standby led at all. Someone here shared with me the schematic of the power supply, and checking the voltages, I see right after the resistor R604 I'm getting 1.6 v which is too low for enabling the Gate of the Q601 mosfet (the diagram says 4.2). On the R614 resistor I'm getting 181 V in and 117 V out, then through R603 I'm getting the same 117 V in and 59.9 V out, finally getting the latter voltage in the R604 BUT getting just 1.6 V out, which is the voltage that goes on to the Gate of the Q601...

                                      Philips 8200 series 65PUS8204/12 stuck at Philips Logo

                                      Philips 8200 series 65PUS8204/12 stuck at Philips Logo, it does not reboot it just stays on the logo.

                                      It does power up when pressing the power button.

                                      I already try the power button while plugin the plug with no result.
                                      Also put the latest firmware autorun-TPM191E_R.001.004.100.000.upg on a MBR/FAT32 USB stick at USB port2 with no result either.

                                      Could this be an PSU or eMMC issue ?

                                      Philips curling iron - is this a common AC cable?

                                      Hi all,

                                      Wife has 2 Philips hair curling irons half defective - after learning how they're supposed to work and testing them, it turned out that both have defective power cables, and both on the same place; broken wires due to wire bending.
                                      As they were both relatively easy to disassemble, and cables are plugged not soldered (as they can rotate in the handle), I was sure it would be easy to find replacements. But - NO! I'm unable to find anything similar on ebay or Aliexpress.

                                      Not sure if this is something Philips proprietary, or a standard, but the cable plug...
