    Full refund from UTs on my order 50x30F131s. UK buyers Panasonic B1JBDN000004 (30F131) are in stock from sparedparts + chsinteractive (Charles Hyde) expect to pay £3.50+ each and they should come in a nice Panasonic parts bag.

        Well the refund failed to show back in my account so am now claiming through paypal and sent the IGBTs off to Toshiba for them to look at with notes of were and when they came from.

          I too was a victim from an ASS CLOWN on ebay, here in the states.
          Bought his repair kit for TC-P50S30 SC board and they all went a pop pop.
          Let us know if a good batch starts showing up.Oh Christ, that sounds like drug lingo!!!!

            I thought i just had some bad soldering on my part but it can be that i use bad IGBT's? I have like 6 TNPA5349 boards here. One board had 4 shorted IGBT's , all 30F131. Replaced all 4 of them with parts from china and i got like 5/6 loud bangs. All known parts on the board got shorted.

            This gives me hope though , just need better parts and im not afraid to buy original panasonic parts. I'll follow this thread.

              I bought a repair kit from shopjimmy this past weekend for a tnpa5349 and after installing the 4 IGBT's and hiooking it up, I heard a pop fiz and smoke.
              But since this was my first attempt it could have been my fault.

              Will probably my last attemp at repairing them myself.

                Sometimes you also need to replace the small ic also. It can be that the igbts you got are fakes also.

                  "part is discontinued since 2015 ,....... no replacement part.......
                  You may want to check IR part no IRG6S320U is a suitable substitute for GT3F131."

                  The IR product is also obsolete.

                  No news about authenticity.

                    AliExpress seems to have the IRG6S320U (10/20 pcs), but the web site claims Free Shipping! and then charges DHL rates for 3 to 7 day delivery.

                      But why take IRG6S320U if you can use the RJP30H2A?

                        So this evening i decided to repair the TNPA5349 again but this time with just the RJP30H2A instead of the GT3F131
                        Just to be sure i also replaced RFN10 and RF1501 as they measured short also. Short went away after removing the IGBT's but i had them laying here so i thought , just to be sure!

                        Replaced all parts and again RF1501 was short. Reflowed some parts and the short was gone.... ?

                        I took hiding behind a corner and plugged the mains in. I was waiting for the "pop pop pop pop" but nothing happened. It did turn off but now with 6 blinks. This means the DG302 or IC is bad. Will do some further checking but im already happy that the board is still working and did not blow up like with the fake 30F131.

                          DG302 are all ok. Tomorrow i'll replace IC504 and the small ic next to it. Fingers crossed!

                            Picked up a Panasonic 50GT30 today for little money that went out with a big bang. Owner wanted to place the tv with the dumpster lol....
                            When i got home i turned the tv on and as aspected , 7 blinks! Took the board Ysus board out and all 6 IGBT's were short together with RF1501 and DAF30. 1 IGBT was blown of the board. Removed just the IGBTS and the short on RF1501 and DAF30 was gone but replaced 1501 just to be sure.

                            Replaced all six parts and the diode for the RJP30H2A / RF1501 and tv turned on and is working great! Thanks for the tip TW2005!! , Im not going to use the 30F131 again until there is a good supplier for the parts. Also i now know that i can fix these boards when nobody has played with it before....

                              hi everyone i couldnt reply to previous comments,buy with a move to larger workshop batch1412 batch 1117 all fake under rated igbts they been re etched
                              some 1412 batch are good but the fakers have copied the batch numbers i test my igbt on diode test using postive probe just tickle the gate and then check on diode drain and source should read 1.8v on diod,or better still using variable power supply stick 4.8v on the gate and you will get the igbt saturate,i sold so many kits for panasonic i mkae sure all mosfets are ok but now it seems gt30f131 are getting hard to get i even had some direct from panasonic out of spec i am looking to add eqivulent igbt anyone any idea i was going to try fgd4536 no idea if it works seen this igbt on lg plasma can anyone shed any light

                                  FGD4536TM , works great as substitute! Fixed my very first sc board with it and tv is working for almost a week now without problems. Extra heatsinks and the tv is not even warm on the backside.

                                    i been looking at spec of fgd4536 wattage bit low side but i think might get away with it i sell so many of my panasonic kits lot of technicians are asking better igbt instead of the toshiba 30f131 which is not in production and is i been told is obsolete i have ordered from rs in uk see how it does the job will be including in my kits now and are well priced

                                      TW2005 and Flocko also use fgd4536 and the one from TW2005 is running for 18 months now without problems.

                                      My GT30 with fgd4536 is working perfect also.

                                        i feel fgd4536 not suitable for gt30f131 the gating voltages required is lower for the fgd and gt30f131 requires more thus possibilty of killig the 15v reg and other bits

                                          lolzz i knew i will cause damage to the board, i fitted 4 fgd igbts and in went dg302 both smd transistor and smd chip rf10 and rf1501 switched on loud bang checked all igbts all ok but damn 15v reg short, blown the face off few resistors. seems fgd not suitible ,confused now all spec are ok on both igbts only thing i can think its switching to much voltage over

                                            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.

                                            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
                                            Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

                                            Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock

                                            I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

                                            This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

                                            Panasonic TC-P54VT25 No image. A or D board?

                                            I have a Panasonic TC-P54VT25 that will power on and prime the display but there is no image at all.

                                            The panel is primed as there is a slight glow from the entire panel. This means the problem should be logic related. The service manual also confirms this and recommends replacing the A or the D board.

                                            I have tried to get the TV to display the test sequence but I have been unable to and I don't even know if this TV has a test sequence or not. I tried following tom66's instructions in post #3 on this thread https://www.badcaps.net/forum/showthread.php?t=26790. There was...

                                            Hi everyone!
                                            I happened several times, in the search for help from the web, to consult this very interesting forum.
                                            So I decided to sign up and I intend to participate actively by making available my knowledge and experience on the subject, I'm a new user but at the same time I'm old in the sense that I have 4 decades of experience in repairing and designing electronics but above all I'm a great passionate about the subject.

                                            Having said that I come to the gist of my post on the forum as the title suggests.
                                            For my passion for technology I'm now collecting several...
