Consumer electronics "war stories"

"Chuck" wrote in in sci.electronics.repair in message ... The receiver tech was flummoxed by one of those large 1970s Pioneer receivers. It had a problem none of us had seen before and we were a high volume audio chain. There was slight audio distortion on both channels, only on FM. We all worked commission only so I was the only one to volunteer to help him out. To cut to the chase, the receiver had an over designed mute circuit that was 3 or 4 stages deep, At the deepest stage there was one of the Sanyo electrolytics that became a common failure item many years later which was slightly leaky. Many electronic devices will have a common problem. It may take a while to find it,but once found, the first thing to look for. Most of them have microchips (that you can't open up and repair). And they have software and wireless or hard wired connections to larger facilities elsewhere where techs can come in and review the software. Many problems seem to be caused from malware or spyware (maybe some even from the government or other places) that intentionally interferes with the intended software provided by the company on the package's label. I worked for a large company and we had a new building built and equipment installed. Right now, I'm not even working. I'm just sitting around looking at space cartoons and video games. |

Consumer electronics "war stories"
OK, we got one of those fancy energy-saving washing machines. After a few
years, it started having trouble filling with water. I replaced the solenoid valve assembly twice over about 6 months, and then started invetigating deeper. The control board had a micro and about a dozen electeromechanical relays on it. The one for the cold water valve eventually developed contacts burned so bad that I was able to diagnose it. I replaced it with a solid state relay, and all has been good for several years. I gues the cold water valve gets cycled the most often, so that relay got burned up first. No problem yet with any of the others. Jon |

Yeah, obviously a current relay or just that kind of an interface or something. Tell 'em about it, so they can buy you a whole new one. You can't get anything if you stay silent.

I assume everybody else that has this or a related model ends up replacing that board every 2-3 years. Geez, I'll bet that is the largest moneymaker they have in this business! So, are you going to tell me that this is a coincidence, or are these thieving bastids designing this crap to fail quickly, then making an equal amount (to the sales profit) by servicing their dead crap? I'm strongly guessing the latter. sigh Congrats on the troubleshooting. -- Courage and perseverance have a magical talisman, before which difficulties disappear and obstacles vanish into air. -- John Quincy Adams |

With wifi connected everything you will simply rent or lease all your appliances, easy monthly payments, no need to spend big bucks appliances. Lets not forget the monthly use tax that will be automaticly deducted from your bank account. Fridge, stove broken? no problem the manufacture will simply remove the broken one and replace it with a factory refurbished one of the same model. Missed a payment on your wifi connected car? no problem they will simply disable it when your in a high crime area. Best Regards Tom. |

I'm strongly guessing the latter. sigh No, I think the evil *******s is pretty appropriate! On the other hand, it may have just been ONE crappy relay. I bought a bunch of parts to put arc suppressors on all the relays, but never did install them. So, there are still 11 relays of two different types perking along merrily for the last 3+ years! I was expecting the rest of the relays to start failing, but that hasn't happened. Jon |
