Hi Jim.
Here’s a dropbox link to an image of the board, blown IC is arrowed….
https://www.dropbox.com/s/9vqnbr2fh8rrynf/IMG_20191109_132840.jpg?dl=0I have the model number! It had been all but polished off (perhaps an OCD wife?), close inspection reveals that it is a W1607W, and the inside of the front panel looks very much like the one in the link in your post #7 iadom.
Many thanks for your replies guys, it gives me something to work on…. when I get a minute! It IS a 7-pin device Dave, I assumed the 8th pin had been cut off as it wasn’t used. In face I have a couple of TNY devices on old boards in my scrapheap so I shall be looking closely at those.
Yes iadom, I do have the full front fascia, but it only reveals the brand, no sign of a model number unfortunately. My latest Win10 PC kept badgering me with MS Drive ‘reminders’ which I managed to turn off, I’ll have a look at getting that going.
I’ll keep you posted, thanks again 🙂Hi @Iadom.
Many thanks for your quick reply.
I understand what you say about ‘exploding’ ICs, I’ve spent many years repairing satellite receivers, amps, TV’s etc. and I always look for the underlying cause before risking a new IC. Often enough there is nothing in the unit itself, we just have to put it down to an external cause like a power spike.
This is a particularly low power smps, basically a standby circuit. So far I can’t find any problems in the primary or secondary circuits so am reasonably confident (cough) that a new IC will sort it.
I’m more than happy to sift through the images to hopefully spot the offending panel (I’ve not seen the machine itself – it’s in England and I’m in Portugal!) but I do have the front panel & hopefully the owner will know the model number.
Where do I find these images – and do I simply copy them across to my Onedrive? (I have it on my Win10 PC but I’ve never used it).
Thanks again, apologies for being so ‘green’.
