Hello everyone,
First of all, I apologize for being absent from the forum for so long.
Some time ago, I ordered the capacitors and have already replaced them. However, I made a mistake: instead of buying 10?F 35V, I purchased 10?F 16V, a big error. Well, it's only two of them, so I will find a way to fix it.
Regarding the power supply, it seems to be fine, but it clicks, which suggests a short circuit. That’s why I checked the bottom board (acquisition board) and found that it is shorted, seemingly on the 5V and 15V lines.
I am thinking of injecting 1V at 100mA to locate the short, but I don’t know which pins correspond to these voltages on the connectors.
Additionally, the rear BNC Signal Output connector is also shorted, which might be a useful clue.
I don’t have the service manual for my TDS, otherwise, I would be able to track the issue better.
Once again, I apologize for being away for so long.
73!
