My GQ4-X programmer has stopped reading 24C eeproms, it will read other eeproms but just not the 24C range. I checked the chip had something on it by using another programmer but its not the first 24C range it hasnt read. Used to be fine just wondering if i have altered a setting which i cant see.

Anybody else come across this?

Make sure you placed the chip on the ZIF socket correctly. The 24C EEPROM should not have any problem. Make sure you select correct device in the software. Different 24C chip has different algorithm.

No just a blank read, put the eeprom in another programmer and it reads

Try an hardware test on your programmer...

Do you not think i have tried that one!

Had it since 2010 and its been very reliable and i know how to use it, i would just like to find out why its stopped reading 24C eeproms when it reads others.

Do you have any serious ideas

Will have to get a replacement, but the import duty makes it very expensive to replace it from mcumall

So what are the results? Every pin responds correctly?

Use a good known 24CXX DIP chip to try, no adapter, lock the chip on the ZIF socket. if it is not working too then the programmer need a service.

Thanks for that, already tried numerous chips all read blank, contacted tech for a cost for the service but with shipping etc it might work out better to buy a new one.

Hi undo the programmer and remove the zif socket pcb and test with a meter each pin on the pcb mounting sockets to the top of the zif socket, as I have had a problem with mine,

No need to open up the programmer to test it, you can simply use the software...

Hi, ok
so if I go to test H/W , voltage diag, what pins on the zif socket are for what voltage, as we need to test for good contact, like I say I had one pin on the zif socket not making contact with the track/side connector,
Thanks for your info,
Thanks Dave

Use the Hardware I/O Diagnostics instead.

Thanks for the tip, took the programmer apart and checked the ZIF socket put it back together and it worked once, messed about with the ZIF socket and it worked again so looks like a i need a new ZIF socket, No in stock and they are under a 10 but postage to the UK is 28 so it might be worth buying a new programmer and trying to bodge my old one.

ZIF sockets should be available locally

Soldered on to a plug on board that fits the programmer ? where from ?

Cheaper to order one than my time changing one, but they havent got them in stock.

Changing the ZIF takes no more than 5 minutes unless you don't have the proper tools.

5 minutes really, 7.5 seconds a pin to desolder, refit and solder a new one

Can you post your 5 minute long video of you changing one on youtube, when you have to change one.

In reality it takes about 2.5s to unsolder each pins and 1.5s to solder them back. That is if you do it manually, using a solder bath would be dramatically shorter. The longest part of the operation would be waiting for your irons to reach their temperature, about 1m, if you start from cold.

YouTube is already full of videos showing how to change parts on PCBs.

If you are not familiar with soldering equipment you are better of paying more to let a machine or someone else do it correctly.

Still if you could post a video in under 5 minutes using a soldering iron that would be great.

been soldered 40yrs + i must not be doing it right by your quoted times.

Like I said previously, lots of videos on YouTube depict how to do it the proper way.

Here is a classic one using ancient Pace equipment. I do not use Pace irons except for ThermoBond Cir-Kit application.

https://youtu.be/M0wI-5YZQm4?t=2804

If you have been doing it for 40+ years and it takes you more than 5m for such a common job you most certainly need to revise the way you do it.

Hi fist thing to do is just try re-flowing the solder on the zif socket pins, use some extra flux,
or get a new zif with pcb,

No, he stated his ZIF is bad after dismantling it so no solder or dlux will do.
