Repair Guru's needed...Magnavox ZV427MG9 VCR/DVDr

So...I guess I entered the Twilight Zone.
Bought a 'scratch&dent' Denon AVR-X1300W.
My subwoofer then went out, blew a fuse. Fixed that and its working good, weird how you notice not having that 'thump' of the sub.
The X1300W got super hot and would not turn on after a couple weeks, Crutchfield replaced it pronto. New one seems to be working better.

It may sound like I am complaining about the new AVR Denon, I do like it for movies.
Its just when the weird stuff started and most likely coincidental.

On to the actual question...
I hooked up the 2011 Magnavox VCR/DVD and POOF! Had been working not 2 months before.
Powers on...then immediately off.
Smells like burnt electrical components.
I pulled it all apart and it looks like a transistor burnt/smoked.
Its the DVD side, looks like.
Car battery died that day too.

I know its not the greatest VCR/DVD of all time but it did work OK. I don't use it a ton.

I can solder and pull things apart and usually follow directions.
So what transistor would I need to repair this? Thoughts?


If this is the wrong place/forum please feel free to point/redirect me.

Thanks guys.

This is with the DVD unit out.

You’d have to have a repair manual with schematic to know the value of the resistor. Maganovox customer service may be able to help. That may or may not fix the problem. For instance – what caused the resistor to burn out?

By the way – what is it about this unit that justifies the high selling prices on ebay?

I have not tried to contact Magnavox...or FUNAI, (same machine).
Was hopping some one would just be like..."oh yea that's a number...transistor" :)

I have no idea why these things are so much money now...I think I paid around 150 bones back in 2011.
Maybe no one makes the VCRs anymore?
Price is part of the reason I was trying to fix it, also I bought a cheapo Craig DVD player, it says ERROR bad region...or something like that with the Magnavox burned DVD's.

I don't intend to sell this one just wanted to see if I could fix it.
When I pulled it apart and saw the burnt TRANSISTOR I figured I could de-solder and replace it.
I was thinking these are NPN or PNP. Just 2 types...I just started to look into this.
I am just hobby level.
I have an old 1994 Radio Shack '300 in One Electronic Project Lab' it has the 2 styles...so i am thinking easy peasy.
If it popped because of a related failure of something else, well that maybe beyond my scope of repair.

It is most unusual for a transistor to blow out like that. You will need a service manual to get the replacement part. More than likely there is a failure elsewhere that has caused this, so you will have to check voltages carefully.

When you solder a transistor you need clip on heat sinks, otherwise the heat of the soldering iron will destroy the transistor.

No one could possibly guess the correct replacement part.
