RT-10 / RT-12 REPAIR BLOG

Recommended Posts

Tommy,

 

That is perfect. I am going to call those 330ohm 5% (Orange Orange Brown Gold) 2W. Since these seem to get rather hot and burn. I will use 3W flameproof replacements. Such an odd failure, but then again people leave these things on 24/7 so I am not suprized.

Where does pin 1 connect for the control board 660045-1on the 640007 Power Supply?  The pin 1 seems to go no where on the PSU? No trace on top or bottom?  The 640007 does not seem to be a multi layer board?

My sub is also dead... looking for a repair.  How much will this set me back?  Is anyone available?

Pin 1 is not connected. If I remember correctly it is a shutdown pin to turn the entire supply off.

And so it begins. I have started my video blogs and will continue to support the repair community with detailed videos of how I do a repair.
