Re: Seiki SC-32HS703N puple lines

Until this happened, it had set on top of a entertainment center in the living room. It was secured so it could not fall. It's at an angle, but that is the entire screen.

The pictures and the pdf I include are from the FCC application, but I've confirmed it matches mine.

I was hoping to get general idea before I start tearing it apart. In my mind, once I break out the screwdriver, I'm committed and I HAVE to fix it.

Is it safe the assume that the backlight works? I've got a pulled main board/power supply being...

Greetings,

I have a Seiki SC-32HS703N that has purple lines like the picture below. After being off for while it may take a min or two for this to happen. I've done just about every reset/adjustment I could find, so I'm going to guess it's hardware related. I do have sound.

Could anyone give me a clue on where to start? I've got meters of various types and have no problem with metering a live circuit(one hand in the pocket helps).

Let me know if more information is needed....

Re: Power supply build quality pictorial. part 2

Just an update. I've been using that supply as my master supply, this means that I'll take an out, lets say 5V and then use that as an input for when I'm doing linear reg work for audio or precision analog work. Or better yet, I used the 12V as an input to a buck converter(3V and 6 amps) that supplies current to a candle/cigarette(yes, I smoke, so??)/whatever lighter.
I did ramp up voltage slowly(I'm got an old true sine inverter that my son had bought broken(he thought he a use for the big caps, but lucky me, he never did)...

Re: the gutless, bloated, and fried power supply hall of shame

Ok, my late father-in-law collected "stuff"(The only way to think of it). We started with two sheds full and ever since he passed(in '10) once a month I go grab something and see what I can get out of it. Dirt, insect's, etc, etc are just the beginning. Most of the time I can get a decent amount of componets or even get it working. I don't think I'll get much from this one.

I present the "King Star" KC-250 ATX power supply. First picture has the written specs:
+5V 25A
+12V...

Re: Power supply build quality pictorial. part 2

Ok, I had to take them from my phone so they are not the worlds best. That computer had sat out in the shed(Where I keep random machines running) for about a year and the PS case was starting to rust(I guess that swamp cooler was just too much) so I'm going to re-case it, move the fan control board over, the fans everything else. I'm going to make that into a bench power supply using a plug in board.

Please note, I had bought that system from ASU salvage years ago and used it as a FreeBSD server until I moved that system...

Ablecom SP-450RP
NOTE: This has almost the same part number as a prior entry. This is a YM-1062PK 450W compared to a YM-1062A 420W. A couple of changes include reducing 5V output to 26A vice 40A and increasing 12V output to 20A from 15A. Combined +5V and +3.3V max power reduced to 160W from 220W. This one also has dual fans, led and reset button.

This came out of an OLD dual Xeon system that was in a SuperMicro tower case.

First off the specs
+3.3V 30A
+5V 26A
+12V 30A...
