Hello!

I'm working on a Wow Wee 9001 Alive Chimp. Trying to bring it back to life as a sentimental piece for someone.

The monkey consists of sensors on the head, ears , motors, and IR sensors for eyes. It will react to movement and touch. It also has a large remote controller to control movements and to program.

When I opened it up the only visible damage was this transistor pkg. Code: BAP59 Pkg: SOT-89 (See attached Photo)

After looking up some SMD codes, the closest I came to a replacement was the following from DK. https://www.digikey.ca/en/products/detail/rohm-semiconductor/2SB1132T100R/1158569

I replaced the SMD transistor pkg using the DK replacement. Powered on using a benchtop DC power supply at 6V. The manual says it requires 6V 3.5A. (Manual attached) The smd transitor started getting hot, to the point it began smoking. Removed power. I assume this was the problem to begin as the original component was smoked. (See attached Replaced SMD Transistor photo) Note: the middle pad was not electrically connected to anything, It came off during desolder.

I replaced a few caps that I had on hand.
Blue=original
Black=replaced

I later found a shorted component in series with the VCC to the control board. (Ceramic Cap Photo attached) I didn't have the correct value on hand which I believe to be 11pF? So I replaced it with a tantallum capacitor that I had on hand just to see if I would get any change. Powered on, drew almost 2.8A. Same thing happened, SMD Transistor got hot again.

After this I replaced the following:
-zener diode
-op-amp IC

I am not really sure where to go from here. Any advice would be greatly appreciated. I'd really like to see this thing work again.

I've attached a picture of the boards in the whole unit as well as a photo of the chimp in case anyone is curious.

That shorted ceramic capacitor is not a capacitor. It is either an MOV or a PTC resettable fuse. In the latter case it should read very low resistance if it is working correctly.

Great. Thanks for your input!

 

Hi Anna, I was wondering if you were able to fix your 9001 robot chimpanzee? A friend from work ask me to take a look at one that makes a short "burp" sound when you turn it on then does nothing else. Any information would be helpful.

 

Imagine waking up and having that looking at you.

 

Anna, curious if you ever got this figured out. I’m actually waiting for a replacement BAP59 for mine as well, but I’m not sure if that’s the initial failed component or a symptom of more issues somewhere upstream. I’ve already replaced 2 capacitors and a resister, and this is the last component I can see as being damaged. Also, have you only opened the base, or did you ever get up into the head? My assumption is that there must be another controller board in the head itself since the board in the base only seems to control the speaker, one motors in the neck and then there’s a rainbow ribbon cable into the head. There don’t seem to be any ic chips or memory on this base board to control the programmed actions.

 

This is an old thread.
