Well I started it seems unsoldering to old solder is really hard.oh will do because I am learning more than I realize definetly wanna see it thru.

Re: Magnavox 19md357b REPAIRED!!!

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

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.

Re: Magnavox 19md357b REPAIRED!!!

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?

Re: Magnavox 19md357b REPAIRED!!!

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

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

Thanks so much for the replies! I'll post pictures if/when I have the thing taken apart.

Re: Magnavox 19md357b REPAIRED!!!

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.

A photo - probably does not help ..

Re: Magnavox 19md357b REPAIRED!!!

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

Re: Magnavox 19md357b REPAIRED!!!

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.

Re: Magnavox 19md357b REPAIRED!!!

Look, see the bad caps? I'm almost ready to begin the repair - yay!

Re: Magnavox 19md357b REPAIRED!!!

Look, see the bad caps?

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