Re: What Is This Component?
Will do and thank you budm! I'm learning a lot more than what the Electronics for Dummies book had in it and I really appreciate it.

Re: What Is This Component?
Won't I burn something out further down the board by going with a 4A version instead of the original 2A?Leave a comment:

Re: What Is This Component?
Yes, that is exactly what it is from! I'd like to think I can replace just the fuse that is dead and the diode but I don't know what a comparable part would be....Leave a comment:

What Is This Component?
It's next to what looks like a couple of diodes, but it only has two legs instead of three. It's blow out and I need to replace it but I don't know exactly what it is so I'm having a hard time finding the part.

Re: LG 42LH40 - No Power
If it helps any, the fuse by the power input is also popped.Leave a comment:

LG 42LH40 - No Power
I have an LG 42LH40 that no longer powers on, owner reported a loud pop and it shut down. I believe the schottky diode blew out on it but I'm new at TV repair and I'm curious that if I replace the component will that fix the TV or is there a good possibility of another component being the cause for the diode to fail. Below is a picture of the diode, still on board. All the caps look good, however their is a ceramic disc cap by the fuse, it has a plastic coating on it that is all sticky so I'm thinking of removing to test the cap, not that it's goo that leaked from the cap.

Re: What Solution To Use In Ultrasonic Bath?
Sounds cheaper than IPA but I'd be afraid of not getting all the water out, even with forced hot air. I might try it on some of my junk things around here and see what happens....Leave a comment:

Re: What Kind of RAM Is This?
Ok, so I found a board with the right chips on it, replaced the suspected DIMM and the Tivo does the same thing, blinking green light, heat up the chip and the light goes solid and the Tivo works.
Ideas? I don't see anything wrong in the area of the chip I replaced.
I think I'm going to reflow the side of the two other dimms closest to the suspected dimm in case it's a cold joint along one of those instead.Leave a comment:

Re: What Kind of RAM Is This?
I think this is going to be a bust. I don't have any micron dimms and this is going into a 1st gen TiVo that has the 4 modules soldered to the board. It's a different story if I could just desolder a 128mb chip and put it in it's place, but I doubt that'll work.Leave a comment:

Re: What Kind of RAM Is This?
Good idea tibd, I did that twice and still no joy, but when I heat it up with a heat gun it powers up every time. There are a few small smd caps by the module as well, I ran the soldering iron over those as well, but I might remove them instead and test them, there is only 3 or 4 so it's not a big deal, only problem is I have no idea what voltage or uF they should be.Leave a comment:

Re: What Kind of RAM Is This?
Ok, so it's a Micron module. Any idea what the numbers on it mean though?Last edited by Nerfinator; 03-06-2015, 12:47 PM.Leave a comment:

What Kind of RAM Is This?
The photo is of a memory module that is going bad in a TiVo. I know it's the one in the picture, because when I power up the TiVo I get the green blinking light of death but when I heat up this specific module (there are a total of 4) it will come back to life. Turn it off and let it cool and back to the green blinking light of death. My question is, does anyone recognize the company that makes this module? I'd like to assume that I could get a DIMM and desolder one from it and solder it in place of this one to replace it.
As always, thanks in advance, I really appreciate it!... -
Re: Are These Capacitors?
First and formost, thank you all for your input and expertise. As a person that never really did anything with electronics and now diving head first into them, I am continually amazed with how little I know.
As for bad sound, no. The photo is of the input control board for a 60" Sharp that sounds like it has a bad LED driver board (panel death). I'm just a rabid dog when it comes to stuff like this and don't want to admit defeat but as I've already replaced the T-Con and power board and I've ordered a new input control board, I think I...Leave a comment:

Re: Are These Capacitors?
Interesting Agent24. Is there any way to visually determine if an inductor has failed? I see some blue coloring on the sides (as per pictured) and the top corner of three of them look oily-wet.Leave a comment:

Re: Are These Capacitors?
Ok, cool and from the sounds of what an inductor is, I should be able to test it by using a continuity meter on each terminal, if it chirps, it's good, if not, it's bad, right?Leave a comment:

Re: What Solution To Use In Ultrasonic Bath?
And after reading through these (some of which I read before I bought one, so go me go!) it sounds like it's safe to use on smd populated boards. Well, I have some deadish boards laying around, I guess the only way to be sure is to test em, right?
Thank you everyone for your posts, I really appreciate it!...Leave a comment:

Re: What Solution To Use In Ultrasonic Bath?
So since I bought this ultrasonic bath for trying to revive water damaged cell phones which are full of smd parts, it was a waste and I should just return it?...Leave a comment:
