As a former owner and Chief Engineer of a Sony Master Service Center I can assure you that the best procedure for dealing with a broken warrantied item is not taking it apart and trying to fix it yourself. When something fails under warranty, don't smack the product -- go back to where you bought it and smack the salesperson's desk.
TomT, that sounds like that game where everyone gets in a circle and the first person whispers something in the ear of the person next to them and so on. Once the message gets all the way around - it is completely different from the original. I guess that shows the importance of documentation, although you did mention an "official" procedure had already been documented. Any engineer worth his/her salt should be able to transfer the idea of a documented solution into another method if it makes sense, but it looks like junior wasn't grasping the concept - he was merely doing what he thought he had been told...
BobDJr, those were the days...I recall my TI99/4A with its "state of the art casette recorder"...at least the chips on yours were socketed and not surface mount like today :)
I'll just remember to be ready to "duck" if I see you getting frustrated - the trajectory of a "spiked" screwdriver can be unpredictably if not aimed well - I can say that from experience ;)
I can relate to the "hit it with a hammer" solution. I worked for a large telecommunications company. We used to have carrier systems that used quartz filters. Sometimes the filters would grow "whiskers" that would short and fail a carrier channel. The Labs guys recommended a procedure that removed the filter, place it on a 45 degree plane made of plywood, allow it to slide down the plane. The controlled impact would break the whiskers and make ithe filter operational. This was documented with drawings and detailed instructions.
The procedure followed the law of entropy as it was passed down by word of mouth. One technician found he could tap the installed filter with a rubber mallet and get the same result. It went further to the point of my finding a new junior tech standing on a ladder with a 22 oz ball peen hammer poundin on a bent steel frame "fixing a filter". He would up nearly destroying a complete bank of a dozen filters.
Nancy, the starter thing comes up occasionally on Car Talk, and Tom & Ray give the same advice as your husband. Then they usually tell the caller to go get it replaced.
(Years ago I was getting *so* frustrated trying to load a program from cassette onto my 48K 6502 computer (wink) that I picked it up about 2 feet & slammed it on the desk. IIRC I had to replace 7 (socketed TTL) chips, so now when I get *that* mad I spike whatever screwdriver is handy.)
Hubby just told me about another smacking trick. If your car won't start, smack the starter with a hammer or a piece of wood - there is a good chance that it will reseat the brushes (its a DC motor) if the starter is bad and your car will start (maybe) (once)...worth a try...
Yes, Nancy, you probabloy did. I was surprised by how consistently effective the smack was. It was also interesting to see how well the kids adapted to the reality of the smack -- and how to do it just right. I guess it's a matter of motivation.
JimT, I agree completely in that frequently we have sacrificed quality for cost reduction. I used to buy a printer with the expectation that it would last five years or more because they actually used to. When I purchased one that crashed after two years and commented to the salesperson how surprised I was, they responded that 2-3 years was the normal life expectancy. We now live in a throw-away society and that is a shame.
And it still is today, Ann - I had lunch with a friend today and when he got in his car to leave and turned it on, the AC blower was not working. He nonchalantly got out of the car, popped the hood - and gave it a good wack. When he got back in, it was working!
For 3D printing to make the jump from rapid prototyping to manufacturing, engineers will need to find easier ways to move products from their CAD screens to their printers.
Gigabit and PoE are two networking technologies moving ahead in tandem as industrial users power remote Ethernet devices such as IP security cameras at 1,000 Mbps over existing CAT5 cable.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
