            Flow some new solder into the joint first. That will help melt the old solder.

                How did you make out? I just replaced a few capacitors on a 26" Magnavox. Very simple. High school electronics came in handy. lol

                  hoping the caps get here soon.Like i said in my previews post. when desoldering to old solder is was very hard but someone gave some great advice and solder new top of the old and that will make it simpler to extract. Name is dood and thanks to him a million.

                      Re: Magnavox 19md357b REPAIRED!!!

                      Hello everyone. This is my first post here. I googled Magnavox 19md357b and found this thread. I garbaged picked this same tv/dvd player combo this past Saturday. Plugged it in, came on for two seconds, saw a green line and heard a noise, then it went blank. This was my third attempt at repairing an lcd monitor or tv. I'm two for three after replacing three bulging and leaking caps.
                      All three were 1000 uf 10V. I replaced with 1000 uf 16V. A bonus was a dvd still in it of the movie " I love you man". Worked out well for my daughter who's 19" lcd tv had a bad speaker. Gave her this tv and replaced her 14" lcd monitor (previous repair 1 bad cap replaced) with her tv with the bad speaker.
                      Thanks to all for the info found here. Much appreciated.
                      Mike95 in NJ

                        OK, so I have most of the information I need to try to repair this TV. When I order the caps listed in the first post do I need to specify a brand or just this, for example: 10000uF 10V?

                          You can order them from www.Badcaps.net to remove all doubt of what you're getting. He has low ESR caps here.

                            You need to order "low ESR" caps. For a SMPS application, low ESR (ohms) caps are required.

                            A number of companies like Rubycon, United Chemi-con, Panasonic, and Nichicon make quality low ESR caps.

                            A complete list is here at

                            https://www.badcaps.net/forum/showthread.php?t=2280

                            Members here like Panasonic FR, FM, and FC (in order of lowest ESR). This immediately simplies your choice down to one company and a few series of caps. PlainBill has written instructions on how to order from digikey at

                            https://www.badcaps.net/forum/showpo...33&postcount=2

                            Or as Dgtech writes, you can order them from this site at

                                I know I should probably have more training and experience to try this but figure I have little to loose; the tv won't work and I'm not going to pay to have it fixed.

                                So -- I'm in the process of taking it apart and have the base unscrewed and the back of the monitor loose and I'm at the point where I need to detatch the small, delicate connections to the DVD player part. I can see how to detach them but how on earth am I ever going to get them reattached when it's time to put the whole thing together? It is such a small, tight space to work in.

                                    They just slide out. Use needle nose pliers if you have them. If not, just give a little wiggle and out it comes.

                                      Thanks for the support!

                                      Also, I found that there is a removable panel that makes this more accessible - that will make it MUCH easier. Posting a pic for other dummies like me!

                                      Gently but firmly just pull it off.

                                          They look like Capxon brand? If yes, they make terrible caps and have a poor reputation for reliability.

                                            Mats / mods: detected and repaired GPU fault. Cant seem to test after!

                                            Hello.

                                            GPU came in, green lines. Spent lots of time using to get the Mats / mods drive working (found on youtube).
                                            Found issue with a RAM block
                                            Replaced, green lines gone.
                                            Trying to test again, assuming getting the false positive. Originally had over 1K on a single bank. Now getting tosses low between banks.
                                            Used a good card to test and same results low errors 32+.

                                            I am just search for some form of command to do a full test on the GPU.
                                            I just ran the mats command with my good GPU and passed after roughly 40 min.
                                            The repaired one, ran...

                                            A2338 M1 Not turning on - Repaired slightly but still having issues

                                            Repaired a customers computer, had a faulty APL 1097 chip and replaced, all well, not shorted anymore, however I am finally getting 12.28Volts on PPBUS_AON, however it stays at 12.28 and doesn't increase to the normal 12.60 Volts. I read that this is the cause
                                            • If the voltage is approximately 12.28-12.35V, it may indicate a communication issue between the SOC and PMICs, or corrupt firmware.
                                            ​Can someone point to me what would be the next step to fix this. I can feel we are getting close to fixing this board, however this is a data recovery and we need to fix the computer to recover the data....

                                            MacBook Pro 820-01987- condensation damage repaired but has sensor issue

                                            Hi guys.
                                            Got a customer MBP 2020 which has a dad of corrosion from condensation, resulted in no power at all.
                                            I replaced the corroded components and repaired the traces. Restored power and now Iccan get to login screen.

                                            But when the CPU gets warm (not hot) and fan gradually starts spinning faster and then MBP turns off. Pressing power button turns it back on for couple of seconds then it turns off again.

                                            Seems sensor related, but it won't even let me get as far as running the built-in ASD.

                                            I can get back to you later with the components...

                                            Magnavox 27MS5402/17 CRT - no picture, flashing green light

                                            I'm going to assume my beloved Magnavox CRT is toast, but also figured maybe this was a good opportunity to dip my toes into he circuitry waters and maybe learn something new. Also, I don't want to trash it if it's a fairly cheap/easy fix!

                                            My 20-year-old Magnavox has gotten me and my kids through many a gaming console change and worked great up until the other day. Following a long distance move, it sat in our garage for a year and now that I brought it in and turned it on I get no picture; instead, a green light blinks on the front of it; 7 flashes, one long flash, then 3 more...
