Thank you!
make sure that you are good with a soldering iron, I am not, so later when I get them I will find someone who is to change both of them. you don't want to make a mess on that board, in my case that is exactly what would happen if I tried
Me too Graham! You have to know your limitations when working on these projectors, and whereas I can get by soldering microswitches, motors etc, when its down to PC board level I just KNOW I would butcher it up. You also need the right equipment. The guy I go to has a precision soldering iron with a digital temperature read out, a precision solder sucker with a motorized pump, and he does all PC work under a microscope with intense illumination. And above all he has years of skill doing this kind of work for the US military, who don't mess around with their specifications and requirements for electronics soldering.
Hello at all!
I have soldered a little Bulb on this Board for the rew and take up Motors where the Voltage come in.
A Bulb make a Short when swiched on. So it gives a little Spark on the Contacts of the Relay.
A DC Motor did not give a Spark when swich it on.
This Spark clean the Contacts in the Relay.
Since I have done this every Relais is working fine. No Problems any longer.
