Elenco MO-1252 35MHz Scope Part 3: Repaired. Wait..what?

I know, right? I accidentally fixed it! I have learned that just replacing caps may fix a lot of issues, but you really need to take the time to see what cap failed and look for other issues. A failed cap may cause damage to other components in the circuit. Just changing the caps and hoping for the best is a lot like throwing a bunch of parts at your car and hoping you fixed it. Diagnostics help narrow down the field and ensure you are fixing it right. In this case, after the visual inspection revealed some acid adhesive damage in the power supply, I removed and tested each cap. Problem was, they all tested good. A 27 Ohm resistor that looked heat damaged turned out to work just fine. I powered up the scope on a current limited supply and was very surprised to see no excessive current draw. I tested all the transformer voltages and found they were dead on the money. Same with the power supply outputs. At first I thought the CRT was dead as it did not appear to glow, but adjusting the channel position brought a trace from the bottom of the monitor that actually scared me! So, there you have it. Magic flux and some solder seems to have brought a very nice scope back from the dead. I will be doing a cap job on this in the not to distant future as I don't want any of that acidic adhesive residue causing issues that will be more difficult to repair in the future. I hope you found this interesting or helpful. Thanks for watching! ... https://www.youtube.com/watch?v=RJ0Z5qxGx4w
