What do you think? Fixable?
So I got a 40" Dynax (Best Buy?) TV for free, with a note that just says "won't turn on."
Opened it up and found that the huge capacitor had literally blown its top (piece of shriveled plastic), a blown fuse, and this:
Looks like I need a new one of these since the on there is literally melted:

Replace that huge capacitor, probably replace all the surrounding resistors and other bits and bobs.
Think it's fixable?

I'm in the process of going through a bunch of old mac stuff I've had kicking around. My interest in the hobby has waned significantly in the past few years (though browsing over a couple forums here almost make me want to finish my SE/30 webserver, my Power Color ClLassic, my 7500 linux box, my 9600G4, give my Quadra 605 a non-LC 33mhz 040 and affix it with a scsi->IDE->CF setup since it's currently hosting a website.... list goes on *cough*)
A few years ago when I got my hands on a Quadra 630 (ah, see, what was meant to be the source of my non-LC 33mhz 040 chip
), I got the machine off ebay from a lady who worked at MacWarehouse way back in the day. Se was within driving distance, and when we talked on the phone, she was pleased to find out I was a classic Mac fan. When we met up, she unloaded the entire trunk and rear-seats of her Inifiniti into my car D: She said over the time she worked there, they had given her promotional copies of software just as a trial so she could get a feel for them if customers ever asked her. She never did much with them, and so I now have all of that along with the other things she passed off.
I'm trying to get rid of this stuff now, though, because it's just taking up too much room and I no longer have the time or attention span to sit and fiddle around with these old machines anymore :/ I have a simple 2ghz sempron that has run XP for 5 years straight with no hassles, and my PM6500 w/ 500mhzG3 and tons of upgrades still serves its purpose now and then.
This is a list of all the software she unloaded on me.. I could still use a couple of the programs but I just can't sit and fuss with them anymore. They all seem to have their own license/serial number, and some are even unopened. I'll assume most people here know what the programs do or can research on their own... if necessary I can give a description of what a specific program is. Here they are in no particular order:

Square One v2
HyperStudio v3.1

Art Dabbler PPC (Might also have Kai Photo Soap and Kai Power Goo in the box, couldn't tell)
Color It! (looks like the first version or something, can't tell)
Avid Videoshop 3
Corel KPT Vector Effects 1.5 (plugins for something?)
Kai Power Show
Pixel 3D (Windows 3/95... dunno how this got in here)
Ray Dream Studio 5
Terrazzo (texture & tile application)
Macromedia Director 3.1.3 (looks complete)
Poser (PPC)
Aldus Persuasion 2.1
nik Multimedia Photoshop 4/5 plugin packs:
-color efex pro!
-sharpener pro!
-efex!
-sharpener!
-type efex!
-color efex!
I don't even know what to ask for these anymore... partly because I'm wicked broke, and partly because I just want to get rid of them (but still know they'd go to some use), so I'm kinda conflicted. If there's something you want, contact me with an offer. Or if you wanna just take it all in one batch, that works too

I'd ask that you pay for shipping, but since it's software, I can ship it media mail for dirt cheap.
oh, also, if I don't get rid of this stuff by the end of the FIRST WEEK OF OCTOBER, I will be THROWING IT ALL IN THE GARBAGE.

It would help a lot if you can figure out why it blew in the first place. It seems like something shorted out to cause those parts to burn up and blew up the cap. I would hunt around the primary side of the power board, a major failure is almost always caused by something on primary side. In my experience, failure on the secondary side almost never burns up like that, the circuit (via optoisolator and switching transistor) usually shut down the whole thing when there's a problem on secondary side.
Parts are cheap enough. Could have just been a power surge or lightning strike that took it out. I would check for a direct short once you replace those parts and BEFORE you try to power it up.
You can also buy the whole power section from somebody with a working unit but cracked screen (look on ebay for that model).

That is the standby 5v circuit. It likely went when the cap went. The cap saw extreme overvoltage or possibly too high of ripple current.
You will need to change all the parts in that regulator. Diodes included.
But..... you will need to check the mosfet in the PFC boost circuit as well, it could have went out of regulation and blew the cap as well.
There are many many things that need checking. Overvoltage seems to be the cause.
It might be far easier to replace the power supply.
But you may find the mainboard dead as well.
Another scenario involves the main CPU shorting out when a surge/spike hits the HDMI. this will overload the regulator and blow up the power supply. I have seen this a few times as well. Inspect the HDMI ports for surge/blast damage. Cheaper tv sets route the HDMI directly into the processor, makimg it highly vulnerable to spikes. Older/more expensive sets use an outboard hdmi to Rgb converter IC before it goes into the processor.
I have changed dozens of those ICs, because they fail and dont take the cpu with it. But the cheaper more integrated processors do not survive.
