Viewsonic monitors
My 2 year, 11 months and 1 week old Viewsonic flat screen monitor crapped out recently. Yeah,
that's right, it had only 3 weeks to go on the original 3-year warranty. I called Viewsonic and they gave me a RMA for return to Walnut, CA. The 19 inch monitor was replaced with a 22 inch model of better specs than original. I can't say enough about Viewsonic. Bob Swinney ** Posted from http://www.teranews.com ** |

Bob Swinney ** Posted from http://www.teranews.com ** My 2 year old 19" LG Flatron started blinking on "wake up" a couple months ago. Warranty - 3 Yr. on monitor itself, 1 year on back light. I contacted the local LG repair depot and was told that they don't repair, only replace monitors and gave me the contact info. RMA was declined since they diagnosed the problem to be the power adapter and gave me a phone # to give them my shipping address. The package arrived three days later, only to turn out to be a power cord (billed out at $17.30) After several e-mails and phone calls, I got P****d off and started a new request for RMA and, once again was requested to phone with shipping information. This time I almost needed a water cooled telephone, but I got results. Sure enough, when the power adapter arrived, I plugged it in and its working fine now, over a month later (due to some idiot part picker/shipping clerk) Gerry :-)} London, Canada |

I'd gotten mine through a local dealer and worked everything through them. No having to ship, etc. |

Hmmmm. Going on 9 years on my Proview 19" CRT monitor. On, on standby
24/7. Best color depth and definition I've ever seen in a monitor. Have 16 years on my Viewsonic 15" CRT monitor at work, same use. Have 2 Magnavox 27" CRT TeeWees, circa 1993, both perfect. 2-3 years old? TSK,TSK,TSK. Why are you lauding Viewsonic for selling you junk electronics-just because they warranty it? That's a given.

I can't say enough about Viewsonic. I cant say enough about them either - or, indeed, most Chinese manufactured monitors and TV's. In warranty, fine - they replace it, just like the $10 toaster at KMART. Write off the old one as a tax deduction. Out of warranty - your totally on your own, no spares, no service data, Chinese IC's with no datasheets available. Not unusual to write off a 3 yo Plasma because the repalcement boards are suddenly NLA ( translated, this means the extra boards they made on the original production run have all been used, so tough titty...) Rat cunning and experience can help - power supply caps are very common, much more than this, forget it. But this is consumer capitalism - as long as your working, in the consumption loop, its not a problem - just buy a new one every 3 years. Wonder how long we, as a society, can keep up this ever increasing consumption....oh, and don't lose your job, or retire - your then out of the loop. Andrew VK3BFA. |

The difference is in the dollar - not the price of gasoline. In the fifties we had *silver* dollars and today a *silver* dollar will still get you four gallons of gas. Not only is someone stealing the silver out of our currency. They are removing the nickel from the "nickels" and the copper from the pennies.

That's not the case with modern electronics.- I believe that is an unintended consequence of Surface Mount Technology, specifically thermal stress cracking. I've worked on the R&D side of electronic development and seen the shift from thru-hole to SMT up close (literally & figuratively). In the lab a good tech can replace almost any part with an iron or hot-air machine. But prototypes don't suffer from environmental stresses like production units, and temperature cycling a single hand-made example doesn't predict the failure rate of 10,000 repaired units. I didn't hear the dictum that consumer-grade SMT boards were to be considered unrepairable until they had been out for several years. Higher-value assemblies such as the medical battery packs I worked on recently are still repaired. Old stuff has the problem of parts availability. Often they only stock an later model's equivalent part which isn't quite an exact replacement. I am slowly becoming the parts maker for the old washing machine and lawn mower. Jim Wilkins |

What a ripoff! What odds would you give that the "tech" had a bad "brain" in his own (or a friend's) projector? sigh I've been out of the loop for several years already, but... Ditto. I went through Coleman College's Computer Electronics Technology course back in '88 and worked as a test tech for an electronics company until '91. We were taught to test to the component level and replace said components both at school and at Palomar Technology. I was just getting a grasp on electronics when they were bought by SKF. I had a chance to bail rather than working for a big corporation (and all the bull**** that comes along with it, including a couple hour commute to Sandy Eggo daily) so I took it. After starting my own company and troubleshooting hardware for several years, I discovered the fun of software troubleshooting and training. After I built my first website, I found that even -more- fun and that became the focus of my company. The t-shirts and glare guards came later, during times of boredom. g To make a short story longer, I got out of electronics in 1991-92, shortly after getting in. Motorola's new radio equipment all had to be shipped back to the factory for the first several months. They simply wouldn't release service info (we were an authorized Motorola Service Center) nor any parts for them. They wanted to see every failure at the factory to determine what was failing and why (so the story went). On one hand, I can see why they wanted to do that. On the other, since you're authorized, why should they want to do all the work? Strange. When they did finally release service info, many small parts couldn't be had, only assemblies. Many times the schematics were only block diagrams of these module/assemblies. Parts pricing was such that it wasn't worth fixing a lot of the time. Suckage. My friend Bob works as a tech for Hobart (no, their foodservice division) and has to go with assemblies most often, even if he knows which particular component failed. Companies who charge $100/hr+ find it cheaper for their clients to replace assemblies. (They wouldn't lie to him, would they? I don't think Motorola was doing anything much different than everyone else and I sure things haven't changed much since I got out (shrug). I'm sure it has only gotten worse. If you can't get service info (schematics, operation explained) and parts, it isn't worth fixing... Too often true! The smaller the pieces, the harder it is to get the magic smoke back inside. sigh -- Challenges are gifts that force us to search for a new center of gravity. Don't fight them.

The gear in the ambulance certainly doesn't, I've examined the internal data logs of field returns. It's real obvious when the thing was left out overnight in Toronto or all day in Phoenix. (They took it well, BTW) Critical equipment is tested in burn-in chambers. I built them for the auto and electronics industries back in the 70's. GM parts were cycled rapidly between -25C and +125C while operating. They had CO2 plumbing all over the factory for their temperature-shock chambers. Condensation makes high volume cold testing for commercial-grade products difficult. And they keep on making the same old design "errors" after, what, 50 years of solid sate - cheap flexi bendable PCB's, low grade electrolytics (with known failure curves) heat generating components with inadequate heatsinking, even to the point of making the pads they connect to too small... They don't need to - they know, from engineering knowledge, how long it will last. Automated production machinery wil take care of the tolerances involved and make a "perfect" product... There isn't any one THEY behind this. What you describe is a compromise between conflicting requirements. The PCB designer picks a library of component decals that may fit someone's idea of a solution to his particular problems rather than industry 'standards'. Whoever bought that library probably hadn't test-driven it. Very likely the pads were sized for packing density and manufacturability on a certain brand of pick-and-place machine. People solve their own problems first. For prototypes I generally extend the pads half a millimeter in one direction so I can hand-solder a replacement without overheating the chip. Thermal calculations are handed off to an ME who is too busy to care. They are really quite hard because of all the uncertainty, especially flatness and surface finish. If the heatsink is adequate someone will object to the cost and size. You can design for a Belleville washer properly torqued, then see a flat washer overtightened with an air tool later on the production line. Dilbert isn't fiction. There aren't enough capable and willing engineers to complete the boring end of the design process. They move or are pushed on to the next project while co-ops or lab techs manage the details. From what I've seen, the board designer at a contract house almost never understands the circuit well enough to get the subtle details right and they are under too much pressure to finish it yesterday even if they did. Funny that - oh, and BTW - when they can charge you more than the cost of the appliance for a spare part, they can say they have honoured there spares supply obligation......like, say, the $10 fusible resistor....and as for custom VLSI ic's - pick a number, any number, bang a few zeros in there, and add exorbitant shipping and handling to it... www.digikey.com I try to buy either older, repairable expensive equipment or cheap, disposable new stuff, like a $30 DVD player. That's difficult with cars but my welding machines all have large transformers and fairly simple schematics. My machine tools don't even have DROs. Custom VLSI chips are probably a good part of why electronics are disposable. They are a real pain even at the factory. Most of the board's logic is hidden, you don't have the internal schematic or source code and the programmer quit years ago. I've designed a couple myself and a year later couldn't easily reconstruct how they worked. What's the point of troubleshooting a bad $4 chip anyway? The repair paperwork time costs more than shipping a new board. I am slowly becoming the parts maker for the old washing machine and lawn mower. Good On Ya - thats what RCM should be, and is, all about - to develop the skills to do this stuff ourselves...its "not economical" but we do it for the sheer joy of beating the system. I know how I do and don't use the thing and make a simple functional replacement rather than a full copy of a molded part. It isn't as pretty and may need greasing or tightening or replacement more often than the original. For example, I build up car starter contacts with brazing rod. The brass might last only 40,000 miles but it's easy to do over. The washing machine now has a plug to add transmission oil so I don't have to pull the agitator, and a slinger cup on the bottom where the oil leaks out, to keep it off the belt. The reel lawn mower sits on tires from cheap replacement wheels turned down to fit its hubs (messy!). The ball bearings from those wheels are part of my sawmill, the metal hubs are baseplates for a hoist. Maybe its an age thing, but it rankles with me that perfectly good gear has to be thrown out because a 10c part is No Longer available - thats why I got into metalworking, so I could make the 10c part.... (its turned into another bloody obsession, which I dont need, but what the hell...) Someone else's loss is our gain. Yesterday I acquired a free pool pump motor that doesn't always start. I showed him where to whack it to shift the armature but he wants it to run on the timer. Andrew VK3BFA. Jim Wilkins |
