"No User Serviceable Parts Inside"?

[FWSnake]

This warning is on my 1981 Sony CFS-45 and my late 70's ERC stereo receiver and I was always skeptical of it. Is it advising consumers to always take it to professionals or should it just be ignored if one were to wish to repair it oneself? I'd like to get into repairing electronics myself, but this cautionary sign haults my confidence in opening up the units and getting a good look at what's inside.

Get out the screwdrivers if you want to fix your box. It's a bit difficult to do repairs without removing the rear or front cover.

Just remember to have the unit unplugged from AC.

thanks for the much needed piece of information! This also confuses me as to why this warning was even enacted, other than just cautioning the general market that lacks repair skills.

Thankfully you have access to all these "Professionals" here on Boomboxery. Just take pictures of everything as you take it all apart. Then when you are ready to put it together, start with the first picture you took and work your way backwards!

Also, if you need any help, just ask!

Also a good tip, if you have your box open for repairs and what to test something do it with batteries rather than mains if you are not confident. Safer.

Yes, the user in this case translates to "stupid general public"
It was probably a legal requirement, manufacturers generally don't waste their time with warnings and labels unless they're forced to. They cut into profits.

If you want to practice, go buy a piece of junk model at the Goodwill and tear that sucker apart!

That is really good advice!

Thanks for the advice, but can you explain why doing repair with the AC cord attached is not recommended?

Thats actually really good advice, will definitely do.

Hopefully I don't reach the point to where I'm the annoying moron of the forum board, hehehe

The 'No User Serviceable Parts' meant the device didn't have radio tubes (valves) - which actually were (for the most part) intended to be user-replaceable.

I presume that users serviced them anyway?

The ones that knew what they were doing did...


...and plenty that didn't know what they were doing did as well. Just mind the capacitors - they bite. Even when unplugged.
