Tamper-proofing screws - 09/17/07 11:37 AM
My Aiwa stereo threw a wobbly last week and with it being 7 years out of warranty, I decided to have a go at repairing it myself.
That was until I turned it around on my workbench to find some very strange looking screws holding the rear cover on.
I've got a very large collection of screwdrivers and bits for tamper-proof screws, but this was a new one on me.
It seems that every time I need to loosen a tamper-proof screw, I end up buying a new bit or screwdriver.
Unfortunately, these screws in the back of the stereo were the sort that only screw in, you can't get them out again, there is no "reverse" part to the screw slot.
Anyway, Mr Dremel won that argument and I found a dry joint where the power transformer secondary feeds into the main board, it just struck me as strange that it took 8 years to fail.
Anyhow, has anyone else ever had a similar experience with these annoying screws?.
