    DVD player freezes

    It's the discs, not the player. Where did you get your DVD? Did somebody burn a pirate copy of it for you? That would explain the problem as you never know what system the other person is using. If you're buying it commercially, looks like a bad lot that made it to your area. I'd return it as...

    Grandsons Project

    If you're up and running, good work. If not, are there any part number markings on the IC? Somebody can probably find a data sheet on it for you.

    Auto Channel Search With Antenna TV

    Sounds like a clash between your service provider and the unit itself. If it doesn't clear up in a day or two, you'll probably have to make some phone calls to straighten this out. The fact that it worked when installed, and is now doing something else indicates to me that the RCA converter box...

    Need to know about this part

    If you've got the troubleshooting skills, if you find a transformer you think will work, I'd check those caps and bridge rectifier diodes before I tried to fire it up again. If your transformer burned open-circuit, it may have taken-out more than just the transformer. Good luck with the...

    A simple question on 2.5mm headphone jack

    Yeah, that fourth contact on the plug makes it more than just 'stereo'. Like davenn said, wrong earbud for what you want.

    AMP connector identification

    I'm going to input some trivia here. I do a lot of MilSpec work. Without telling anybody, AMP moved their production to China. I found-out the hard way, that Chinese-built product is not authorized for use in military or aviation flight systems. Depending on your application, I thought I should...

    Op amps with one or no supplies in schematics

    I remember a discussion about this topic here a few months ago. It was my observation that depending on where in the world electronics people received their schooling, and how pig-headed their instructors are, resulted in how they draw their circuits. I think the previous discussion centered...

    "Good" DMMs with bar-graphs - crippled by design?

    If what you want to do was easy, the original equipment manufacturer would have done it. Trying to re-engineer what the designers did, does not seem to me to be a very practical fix. I'm of the mind that if you really want an analog representation of what's happening with a reading, take...

    Publishing my notes and potentially selling them

    I don't see why not as long as you don't plagiarize somebody else's copyrights with your notes. It probably wouldn't be easy to make a comprehensive book-worthy product unless you wanted to spend years doing complete research on the topics covered. But you never know what will sell on eBay...

    HTC Motherboard; need help to ID a component

    Excellent detective work. Congratulations on the fix.

    Was, Were, Wasn't and Weren't

    See it before it completely disappears, you mean, Harald? (Sorry *steve*, I gotta learn mobile abbreviated slang before I can shorten my posts, to save you review time) Good one Hop.

    Was, Were, Wasn't and Weren't

    Ya' know. If we all wrote our posts in mobile abbreviated slang, we could have saved *steve* a whole lot of aggravation time.

    Was, Were, Wasn't and Weren't

    I lived in Japan for a while. What I noticed is that the man-talk seemed harsh, and the women-talk seemed soothing. Often wondered if they've got some kind of separation there between the sexes in the spoken word. My concern about not teaching kids to write, is what's going to happen if we ever...

    Was, Were, Wasn't and Weren't

    My daughter, who is a grade-school teacher, moved to another state years ago. She left a boat-load of construction and other paper products she didn't want to pay to move. A contractor was at my house yesterday working on the plumbing, he mentioned his mother was a school-teacher and that she...

    Was, Were, Wasn't and Weren't

    You know somebody that still writes in English? Fast food restaurants with product symbols keyboard instead of numbers so cashiers don't screw up the cost. Grocery store price scanners so cashiers don't need to know the prices, or enter them. Kids on mobile devices where everything is an...

    Salvage haul - 7/11/16

    If you keep the haul together, put a note in with it that lists the model numbers of the printers you got them out of. My experience is that you may run into somebody who needs a spare part you may have. Of course you'll use the parts as needed for your own projects, but I've found it pays to...

    HTC Motherboard; need help to ID a component

    I can see the second set of pictures. That symbol you can't ID is the manufacturer of the IC. ST Microelectronics That damage isn't from a circuit fault, that's physical damage that may have been done at the factory during installation and just didn't affect the operation of the IC, so they...

    HTC Motherboard; need help to ID a component

    I can't see your pictures. Don't know if it's my firewall, or that the image just didn't load correctly. From your description of what you found, I wanted to say that I have seen IC's with cracks in them. An overcurrent literally 'blows-up' the micro circuit, and can burst the IC housing. It is...

    LG S protection

    Hell. Try the Best Buy remedy. Temporarily disconnect the internal speakers and see if you still get the scrolling msg. If they were right, at least you'll know if the speakers are ok, (or if there's a problem with the amplifier output to the speakers). There are so many cheap components in...

    Repairing old stereo

    Nuts. I, can't do it. I can't find a schematic on this unit either. To people like us, a schematic is a road-map that gets us from one point to another within the circuits. Somebody here might be able to come up with some ideas if we have close-up pictures of the connections to the circuit...
