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.

well ive come to learn that engineers dont give a hoot. They just engineer the crap. they dont have to worry about fixing it.

if they had to fix what they engineered, the electronics world would be 180 of what it is today.

Example: if you ever have to service a 5 disc CD changer trayload mechanism from Panasonic, such as the SA-PM19 or SA-pm29, or SA-PM33, etc etc etc... DONT.. BE WARNED.

I tore it apart and retimed it 3 times already, and still the timing isnt correct and jams at the trays. There are timing marks and holes all over the thing, but the service assembly manual being in broken English does NOT help matters any at all.

well its almostly completely recapped, i recapped all the ones near heatsinks and most of the other ones, i left some of them alone because of the locations,..
i had to adjust the brightness, i must of have bumped it when working on it.
this set has a great picture.
