Ghost in my DD33?

The emitter should be battery voltage, which is 3.2V in your case. If the base voltage is 1.8-2.2V, then Ve-Vb=1-1.4V (which is Veb), whcih is different than the 0.6V you are stating. What is it that I'm not understanding ?
If Veb stays constant at 0.6V and only the voltage at the collector changes, it is a problem with the chip, as being a bipolar it is current driven (and a change in base current would change the collector current and thus the voltage at the collector).
Where did you find that chip ? I could not even find a datasheet for it... Or it is the CX20084 the one that you have ?

 

sorry if im confusing you, i don't have a lot of knowledge in electrical engineering or circuits. You can ignore my last post because shortly after posting i realized i had tested the transistor completely incorrectly. Yes the emitter is 3.2v (Tested with negative lead on black wire and positive lead on the emitter.) I tested the voltage for the base while plugged in but not playing and it was 2.6v. veb makes out to be 0.6, and i believe that's confirmed through when i placed the negative lead on the base and the positive lead on the emitter and it read roughly 0.6v. On a side note i meant the transistor not the chip, i don't think that chip exists anywhere on the internet, at least not anymore. Anyways i went back at the transistor with the diode tester and it also checked out with the negative lead on the base and positive lead on the emitter and collector, they both had values around 710. Again im sorry if im making this difficult.

 

Ok, I understand now. From what you say, it seems that the servo IC is the problem unfortunately. In which case buying a donor board or donor unit is the only solution. However, you must make sure that the donor unit does not have the same problem.
I must say this problem with powering the unit with reverse polarity is widespread. I bought myself a couple of walkmans and portables with this problem in the past. And it's understandable since almost all units used center negative at that point in time.

 

Well I guess that does it then . I’ll be scouring the internet for a board or for parts device, hopefully one as you said without the same problem. Thank you for everything you’ve been a massive help!
