The heat gun I have is a paint stripper. I use it a lot to shrink heat-
shrink tubing but am reluctant to play it on electronics. And I cannot
find the non-contact thermometer I was sure I had.

Viewing the youtube video I think was meant, I see the same capacitors
have bulges in my power supply. So though I cannot pop down to my local
Maplin (like the youtuber) because they have since gone out of business,
I have ordered replacements, fitted three, and the monitor is now
working!

It is sad that a board clearly marked 2007 already has multiple duff
components (assuming they are duff). I notice that the bulgy capacitors
have cross-scores on the flat end, almost like a hot-cross bun. The
scores recall a burst diaphragm, so I wonder if they are a safety
feature for components which are considered quite likely to fail
explosively! The words written on the items include "VENT", which makes
me think that I might be right...

As well as three bulging capacitors there are three flat-ended ones
which are also scored, so I hope those are "good".

I do not have an ESR meter but have noticed many discussions of such in
this NG over the years...

Thanks to all respondents.

Mike.
