Micky <NONONObobbyburns1111@gmail.com>: Aug 24 12:29PM -0400 I took the back of my back seat out of my car and was surprised to see that I have a woofer!   It has 4 wires running down the cone, two on each side. Is that because it has 2 voice coils, one for the left channel and one for the right? So it can combine the signals audibly but not electrically, because if they mixed here, they would get mixed on all the other speakers too?   But couldn't they do that in the woofer amplifier and use a standar speaker with only one voice coil?   Also one pair of wires, unplugged from the car, has 32 ohms between them, and the other pair has 2.5. That's a bad sign, isn't it?   I wish I'd noticed this before I spent $25 for a new foam surround, but the I bought that before taking the speaker out, and since the speaker was facing me, I couldn't see this.   How good do you think it will sound with only one channel? Will I keep steering the car towards the side of the road?

Jorge Ricardo Rodriguez <jrrz.iescd@gmail.com>: Aug 24 08:48AM -0700 Hi all, I am just starting into this world of fixing industrial PCBAs.   As you may know, in this kind of repairing, normally there are no schematics available, most of the times you do not have a PCBA in good conditions to use as reference of what is wrong and what is fine.   I just knew about the VI technique for these cases which is useful, but I would like to know more about it and about more other techniques to use in these cases to debug industrial PCBAs.   Do someone of you have blogs/books/nice online courses with useful information?   I would highly appreciate your help and advises on this topic.   Thanks! Regards

I could ask the dealer but then parts $$$ will go up.....

My guess would be that if the evaporator got too cold and it was in recirculate, open 1/2 of the re-circulate door. If it was not in recirculate, then turn off the compressor if the evaporator got too cold. The temp lever mechanically controlled a water valve.   I tried to look up the parts, but seeing how the door worked wasn't really possible. The real reason I knew is because I installed all of the pieces.   When a 1968 Chrysler "Aftermarket" AC got too cold, you would get water on your feet on turns. They made units that would bolt under the dash in that ERA. This particular mounting bracket used the thermostat housing to mount the compressor.

The Dew point determines when this occurs. Lowering the humidity of the air increases the heat capacity of the conditioned air and raises the dew point.   It's hard to get people to use the AC and Heat at the same time especially when it's cold out and you want to get warm. From a Thermodynamic view, it doesn't work.   See, I use thermodynamics in everyday life. Hot water freezes faster than cold water does. Ice expands when cooled. Increasing surface area increases heat loss. A hat will increase body temperature significantly, A hat prevents heat loss from your head. layering clothes is important. I somewhat regulate sleeping temperature by wearing one, two or no socks to bed. A bare foot in a slipper with an air gap will be warmer than a slipper, and a tight fitting sock. Wet clothes are bad when trying to stay warm.

Most car climate controls abbreviate it to "DEF", and I always assumed it was short for defrost.       "It's hard to get people to use the AC and Heat at the same time especially when it's cold out and you want to get warm. From a Thermodynamic view, it doesn't work."   Again, what I wrote were the suggested temperature knob settings for defrost/defog/de-what-ever. For Heat and AC, the temperature knob positions should be obvious - although my particular owners manual suggests setting temperature knob to approximately the 10 o'clock position when using the Auto climate feature for cooling in summer, and 2 o'clock for heating in winter. I followed the instructions for Auto in summer and so far, has been transparent and satisfactory.       "See, I use thermodynamics in everyday life. Hot water freezes faster than cold water does. Ice expands when cooled. Increasing surface area increases heat loss. A hat will increase body temperature significantly, A hat prevents heat loss from your head. layering clothes is important.

KenO <kenitholson@yahoo.com>: Aug 23 12:23PM -0700 ohg,   "There's no "design" issue involved with your particular failure. It's a simple full wave bridge and bypass filter."   Thank you for the clarification.   Since this is an inexpensive TV do not want to over do things so the Panasonic is not cost effective.   You have way more experience than I do so when you say "the cap in your TV was likely just a bad run of caps at least..." I believe you!   Am thinking about using a Nichicon replacement and have not found any problems with this brand.   Any experience with them? and last is it even cost effective to upgrade any aspect of original 47uF 160V 105C cap?   Thanks again for your comments!

Ken, the cost to ship a capacitor of this type will far exceed it's cost.. If you're buying a few hundred thousand of them, then pennies matter. The cheapest Nichicon 47/160 radial I could find at Digikey that was in stock and could be purchased one at a time is 0.61c each. The cheapest Panasonic is 0.71c.   A 68/200v 105 Panasonic with 10K hour life is $1.14   http://www.digikey.com/product-detail/en/panasonic-electronic-components/EEU-ED2D680/P13526-ND/1086751   In any case, you're going to have to pay shipping. Does the cost of the cap actually matter?

It took a large pipe wrench (the hex top of the rod was above the tank) and a 3 foot or so section of galvanized pipe on the wrench handle and lots of effort to remove it.

Usually if it's not a separate rod, it's part of the cold water inlet tube which introduces the cold water at the bottom of the tank.
