Latest video from Alex at NorthridgeFIX. This time he finds a failed MOSFET in a iMAC ‘all-in-one’ computer in quick time using his thermal camera. :-+ Can any laptop/pc repair shop afford  to not have such technology on their test bench these days ? The technology has never been more affordable and the likes of the Uni-T UTi260B and Infiray C210 are adequate for the task so no need to buy a FLIR E60 unless you really want to  :)

Professional users may wish to consider buying a dedicated thermal imaging system like the Dianyang CA10 as that is configured for hands free use with the image appearing on your computer for ease of interpretation.


Correction : It was Alex’s Uncle “Big Boss” who identified the area of concern with the thermal camera. Big Boss dismantles the computers and reassembles them for Alex. He also does other repair work that does not justify Alex’s time. In terms of first line triage Big Boss helped Alex to identify the failed component using the thermal camera as the PCB needs to be mounted in the bulky iMac chassis for power-on testing.

Alex at NorthridgeFIX has just provided his review of the Uni-Trend UTi260B that he is now stocking in his shop. Alex is a great believer in the use of thermal imaging to aid fault finding on modern electronics. He uses a FLIR E60 camera but has clearly looked into a more affordable model to offer to his YouTube following.

Sadly no. I do not have a UTi260B so have no personal experience of it. There is discussion of the camera by others on this forum though  :) If I had the spare cash I would purchase and review the UTi260B cameras performance, but alas such is not possible at the moment.

Another nice repair video from Alex at NorthridgeFIX. He uses the FLIR E60 to prove a suspected faulty MLC and shows how even the E60 would benefit from a close-up lens for PCB work. In its place he tries the X2 eZoom mode and it works well enough for his needs.

The Exx series focus to around 30cm so a decent close-up lens bringing that down to around 10cm is of great benefit. Why Alex has not pursued this I do not know. I even tried to make a comment pointing to the required information on this forum but the comment was deleted :(
