SDT-S-112DMR relay - where to buy in qty = 1

Re: SDT-S-112DMR relay - where to buy in qty = 1

Thanks for all the suggestions so far. I'm working on this as time and the weather permits. Summer is a precious commodity here in Canada. If it is sunny outside, I'm outside. Today it is pouring rain.

I decided to post a few pictures to make it easier for everyone (since it is raining, the quality of the pics isn't great).

I'm having a tough time taking apart the board connectors. They are shown in 2 pictures and I cannot figure out how to release the connectors so I can remove the input PCB board.

I tried using a pen (blue marks) to depress the "latches", but they won't budge. I tried a small flat blade screwdriver. From the schematics, that board should come apart from the input PCB board.

Once I get that board connector off, I can access the main PCB and test all the components in question.

It may not be those 'latches' which move, it may be the other half of the assembly which is pushed out.

Depending on the design you may need to release both connectors at once.

If the board still won't move, check it's not bolted on to something else somewhere...

looking at Your pictures, it looks like they are soldered together.
The board to the right is the connectorboard to the Main PCB.
To remove the Input PCB follow the step <9> on page 19 of Your servicemanual.

Came across your post looking for more info on a problem with a HK avr125. Have you found a solution.

Found this article

Apparently no 15v is getting to the ic's because a bad cap (possibly) is blowing out two fusible resistors.

Have you found a solution.

Someone else actually fixed it and it was Q901 that was bad.
