N_Cook <diverse@tcp.co.uk>: Sep 30 09:16AM +0100 Will not reliably switch or stay latched in piano or synth mode via the select switch. I suspect the light action switch is too light. Easy enough to remove the keycover and inspect the phosphor bronze action. Is it just a matter of cutting back the spine of the keycap a bit , so the action is farther removed from a hair-trigger situation? All clean and tidy inside the switch.

N_Cook <diverse@tcp.co.uk>: Sep 30 04:14PM +0100 I think cause or part of the problem is the metal casing of the top , containing the switches, has been bent,dished or flexed slightly. The keycaps are then partially compressed by the metalwork. Some padding washers will go in there, as any of the keycaps could be the next affected. Also the wooden end cheeks are loose. Only 2 thin wood screws per cheek , and the wood is now not holding the screw threads. Some bracing plates will go in there with 3 woodscrews extra. Employing the old carpenter's trick of the axis of the 3 screws all angled relative to each other so they mutually anchor themselves in there, also allows longer screws for the relatively thin wood available.

Bill Martin <wwm@wwmartin.net>: Sep 29 09:24PM -0700 Hi, Anyone have a list of "usual suspects" with this HP1740A scope when there is no display at all? Front panel lights seem working, but that is all I find so far. Have not opened the case yet, nothing seems to "smell bad" so far. I won't be stressed if it can't be fixed, I bought it for the nice rolling stand it was sitting on...I have another similar, slightly newer antique scope that is still working that can use that stand.   TIA, Bill M

Also the vertical output chip fails so you will get a trace but no deflection. If you can go over all the joints carefully you might have an easy repair.

It says it can affect 2.5% of the population. I have never heard if it. Surely if it affects that much of the population, I have probably met many people with the condition.   When you first said it, it seemed like it would be a pretty seriously debilitating, but after thinking about it probably not so much.   I would guess you also have close friends and co workers that you can distinguish their faces?

thekmanrocks@gmail.com: Sep 30 04:17AM -0700 Seymore4Head:     Ironically, I can recognize most makes/models of cars by the shape of their headlights at night, as well as most major types of commercial jet liners passing over our neighborhood(we're under a flightpath that takes many of them across to England & Europe).     What I NEED is to be able to recognize the most basic feature of fellow human beings - their FACES for cryin out loud! Watching movies with me is an exercise in patience, as I am constantly confusing similar looking characters. And the condition is not helped by the use of glasses.     I use the example of Hilary Duff and Britney Spears some years ago, when they were simultaneously on top of their careers and on the fronts of magazines. Until I picked the magazine up and read the caption I was SURE Britney was Hilary and vice versa. But most other people, especially women, said I must have been crazy to confuse the two! lol

Phil Allison <pallison49@gmail.com>: Sep 30 03:20AM -0700 ** Hi all,   one thing repair techs dread is being presented with an item for repair that cannot be put under test while in the workshop. Usually, this is because the item requires a missing accessory in order to operate OR is itself an accessory to a larger unit.   Essential accessories could be AC adaptors or multi-voltage PSUs for mixing consoles, IR remotes, power leads with oddball plugs, foot switch units with multi-pin connectors and many others.   A real annoyance is when radio mics arrive with no receiver, or the reverse.   Some customers seem unable to comprehend that repairing electronics involves a LOT of testing - not just final testing ( which they fondly imagine they can do for you) but also initial and continual testing during fault finding and fixing process.   Dunno if Scotty ever said the words in my heading, but he should have - it would make explaining it a lot easier.       ...

It's "Rulycon", a fake designed to look like Rubycon.   These came out about the same time as the "bad caps" scandal a few years ago.   -- (\_/) (='.'=) Bunny says: Windows 10? Nein danke! (")_(")

bitrex <bitrex@de.lete.earthlink.net>: Sep 30 12:58AM -0400 >> How annoying.   > Hey, at least you found it. Thanks for posting what the result was.   > Matt Roberds   Yeah. The switches are that membrane type where a conductive bit of carbon shorts two contacts together. They can be pried open by drilling into the case a bit with a Dremel tool. It looks like over the years the metal contacts had formed a layer of oxidation, preventing a good contact from being made.   Replacing the 4011 stopped the oscillation.

The EPA will either force VW to do a full recall and verification campaign or they could even make them replace the cars. That is what still has to be determined.     -- Steve W.

jurb6006@gmail.com: Sep 29 01:57PM -0700 Possible, but I think the easiest way would be via the ABS. Rear wheels not turning. I could be wrong, I think German engineers get better drugs than most.

That is what still has to be determined.   It doesn't have to be like that. Let's just treat it like another recall and move on! What can I say, I'm a dreamer... ;)

John-Del <ohger1s@aol.com>: Sep 29 02:54PM -0700 > get the new firmware then they get to sue. If not then they would get > no compensation because they have not suffered a loss. > ERS   Owners will NOT have the option to opt out of the firmware being upgraded because the cars are not EPA certifiable at this point. They need to be brought into compliance by U.S. law or be crushed if they cant. If the owner refuses to get an approved fix done, then many (if not most) will fail the car's emissions test and pull the reg (CT).   As far as suffering loss, that depends on the fix. If the firmware (and most likely hardware) changes do bring the cars into compliance, but causes a loss of performance and/or fuel mileage, then the owners have indeed suffered a compensable loss. If it can be shown that the resale of the cars suffered as a result of all of this, then that's also compensable. If the fix actually improves performance and efficiency (long shot but who knows?), then it's a win for the customer as long as the fix doesn't shorten the life of the engine.   If the fix ends up being like so many other recalls, I'm sure VW will also include some VW swag for the customers to compensate for the trouble (VW backpack, key rings, VW feminine hygiene products, etc.) and probably coupons for service and/or extending the warranty.   It will be interesting to see if VW had a fix ready in case the scam became known.
