N_Cook <diverse@tcp.co.uk>: Mar 11 10:58AM I could not find any pics of the internals of these watches, so pic here http://diverse.4mg.com/casio_wr50m_r.jpg The wire to the antenna broke , handling the pcb for this pic and self-weight of the small coil, not before, but it is obviously a week point at the solder points if subjected to a lot of vibration. For the moment I'll clean battery and contacts and reaasemble to check that I can and run for a while, until date 2005 returns presumably, and hopefully find out more info on the internals. The yellow caret marks a SMD with 200mV on it 20 minutes after removing the button cell, 3.06V open cct voltage. Seems 3 crystals relate to the radio blob and 1 for the watch. Red is my mark for +ve so I can solder a pair of wires to convenient spot , to power from 3V to monitor some DC levels at least, next time of playing with it that is. Beware of the tiny phosphor-bronze spring dropping out, on disassembly of the 2-part plastic sub-frame, it connects to the piezo sounder. Battery contact simply slides to release battery. A number of tangs need prizing back with a needle to release the metal screen and 4 spring tangs for the button returns. |
N_Cook <diverse@tcp.co.uk>: Mar 11 02:37PM Reassembled resoldering antenna wire and a small spot of hotmelt glue "strain relief", deliberately leaving out the piezo contact. Watch returned to non-rc function but button A spring must have been misplaced and no function. Could reasign London instead of Tokyo and left in timesetting mode , with flashing seconds. It later dropped into normal timekeeping mode and could then select RC! , we'll see if full function returns and then go back inside with more confidence, to take voltages and play with SM or whatever. |

First, a 125V or a 250V rating will be fine. You'd be best off mentioning the make and model of you VCR. To answer your question these vendors will have a vast array of fuses: www.mouser.com www.digikey.com It is unusual for a fuse to blow just for the heck of it. If it is a typical glass tube fuse, is the element broken or has it plated the inside of the glass? If a second fuse blows right away, there are other issues in your VCR. Regards, Tim |

Unfortunately, yes, especially if you use the term "identical model numbers" loosely, in which case there are often numerous variants of the same basic model even in the same country. IMO the worst offenders are laptop and cellphone manufacturers. When I wanted to buy a high mid-range laptop for my architecture-student son a few years ago, it was a real PITA to choose from, not only different models but also from the numerous sub-variants of each model with slightly different suffixes. One Samsung model alone had about twenty variants!! |

Goof-off or Goo-Gone are probably cheaper per volume, and they can be dripped on instead of sprayed so your supply lasts a lot longer. John :-#)# |

One of the popular cleaners is Nathpha, or like Coleman Fuel. It dries slow enough to use mechanical switch action to clean. For lube I like CRC 2-26. Greg |

I was able to easily lift out the broken button.

It cost the same to mail a $2 button as it does to make a 2K diamond (assuming you're not adding insurance), so I wouldn't call it "gouging" >>Also, how easy or difficult is it to install the button? Will I be able to just pop it in or will I have to unscrew and disassemble anything on the unit? Look at the knob: if it has a flange wider than the space it takes to insert it through the vacated opening, you'll have to remove the transport. OTOH, if it does require transport removal, you can Dremel the button down and snap it in from the outside if you don't mind the wider gap that will result from the trimmed plastic removed. |

Not true. None of those machines use anything else but the shaft to hold the buttons on. If it pops off because the mechanism trades functions with a significant snap (that a bottom skirt might contain), a tiny bit of loctite or even a shmear of RTV will keep the button in place. Besides, there's a 99 percent probability the transport does not have to come out. Most of those buttons just push on the shaft and are held in by friction and no part of the button is larger than the opening. A few buttons are molded with skirts but the vast majority are not. I've seen some high end machines with floating buttons but never on a bottom feeder like this one. |
