I've noticed how manufacturers like to put capacitors close to heat sinks and nice warm wirewound resistors. Often, they just get cooked and fail.

I have a 1991 Sony 27" that used to eat the big regulator IC regularly, about once a year or so. It got so bad, that I now keep a spare IC when I buy them in stock for this set.

The last time I did the repair, I installed a 3" box fan that blows air across the IC and its heat sink. It's a 220 volt fan running on 120 volts, so it runs really quiet. I dont notice any noise from the set. It's been almost 3 years, and the IC is happy.
