OzMate Posted October 24, 2023 Report Share Posted October 24, 2023 Hello everyone and thanks in advance for your help. As you can see from the pic here: https://imgur.com/a/Vvnf6uX I removed today the clock cap and I found some corrosion. I cleaned very carefully (probably more clean will need) with a soft brush and isopropil alcool. I have noticed that corrosion affect some SMD component that now are gone, so I navigate the web looking for pictures to find the missing component so I can but and resolder them. Please help me with the values of the following components from bottom to top: R7G2 = 3K ohm R7G1 = 1.1 K ohm Q7G2= 1AM R7G3 = 285 Ohm CR7G1= A11 R7F9 = 2K ohm R7F8 = 256 Ohm R6F7 = can't find any value on the net Can you help me with those values? Also, any tip to double check? thanks Quote Link to comment Share on other sites More sharing options...

OzMate Posted October 24, 2023 Author Report Share Posted October 24, 2023 Some where already gone in the case, some other literally disintegrated while brushing. Quote Link to comment Share on other sites More sharing options...
OzMate Posted October 24, 2023 Author Report Share Posted October 24, 2023 as far as I understand this is the diagram of that section: But I can't locate the R6F7 and the R7F8 Value seems higher than 84 K ohm. Can anyone confirm this? Quote Link to comment Share on other sites More sharing options...

OzMate Posted October 26, 2023 Author Report Share Posted October 26, 2023 Thanks a lot I need all the missing parts in the picture so r6f7 is just one of them. I guess the effort and the shipping may not worth for a single component. If we can have the reading for start I believe it will be a great reference for others too. By the way thanks a lot and I will let you know if I need the part so we can organise ourself. 1 Quote Link to comment Share on other sites More sharing options...

OzMate Posted October 31, 2023 Author Report Share Posted October 31, 2023 I'm starting to think is a 0 (zero) Ohm resistor Quote Link to comment Share on other sites More sharing options...
Marty Posted October 31, 2023 Report Share Posted October 31, 2023 Not sure what your goal was in removing all those components.... Quote Link to comment Share on other sites More sharing options...
OzMate Posted November 8, 2023 Author Report Share Posted November 8, 2023 Well, the removal of the clock capacitor speak by himself. The removal of other components is simply a conseguence of the acid from the capacitor, they detached themselfs and get lost in the case or destroyed.
