Greetings All,

I am working on getting a Putting Challenge II working and I cannot figure out why it will not start up.

It lights up but otherwise nothing else.

I am wondering if these capacitors are blown or if it is hot glue.

Blown.....Not Blown....what do you think?

Hi Hewitson. Thanks so much for the post. Sounds good. I think I may need to replace the power supply. You ever worked on a Putting Challenge before?
 
Seems common for big caps to be glued down somehow.

Yeah, for large axial capacitors it's kind of common for them to glue them to the boards to keep them from getting knocked around. Some companies did, some didn't. I like the idea behind it... but it's just a PITA sometimes.

Why would someone hot-glue capacitors to the board?
Manufacturers knew op's treated the PCB's like shit and decided to glue them in place to prevent them from being ripped off the board.

Common for large radial caps as well.

Too true... when I see a board that has a large axial up top like that and I have to move the board... I just treat it like a handle.

Common for large radial caps as well.

Good call, see that on chassis that haven't been worked on before.
 
Something I was learned at school: a soldering is not (intended as) a mechanical connection. It is an electrical connection. The mechanical support has to come from the PCB carrying the parts. Of course, with small parts the PCB provides enough support for it. However if the part becomes too big the PCB cannot provide enough support. Thus you will have to provide a mechanical support in some form. The hot glue is one of the possibilities.

Apart from that, in my experience the bigger the cap, the less likely it is to fail over time. The small one's are the one's to look out for....
