Hi Mark,

I don't remember hearing what "the price" actually was. But if the customer can afford the price then replacing the unit would be a good idea.

Mark, I own these on Aliexpress sold good testers which you'll find when searching on "multi-functional led & ic tester".

Portable tester1

Portable tester2

These universal testers are capable of testing much more than only CMOS or TTL ICs. Transistors, Zeners, Leds, Amplifiers, Opamps, and even Optocouplers can be tested. And they do not even need an 9V blok battery to function because 1 or 2 cheaper AAA or AA batteries suffice!

Hey Charles,
Thanks for your comment. You will be happy to know that I always strip down any boards for useful components and also here in Australia we have an 'E-Waste' recycling system that tears down electronic systems for their metals and other useful materials.

Hey Robert,
Didn't think of that -thanks. But for the price of the control box assembly, which included mechanical and hydraulic components as well and taking into account the age and look of the unit inside, it still seemed the best option.
I will keep in mind using an adaptor next time.
Thanks for your comment!

Excellent repair however the control board was not saved still from trash after identifying the faulty and time invested hopefully you will find the ic and reuse the control board elsewhere.Have also learnt a lot from your repair

Good job, Mark. If the owner didn't have much money you could've used a DIP to SOIC adapter, and then used the SMD Quad Nand.

Hey Anwar, you are right. Maybe that's why the complete part was so cheap. After some research, it seems like a fairly common problem and that's why it is so easily available. Just a shame that I didn't get to repair it fully at a component level, but at least I was able to correctly diagnose it 🙂
