I'm assuming there was no rubber strip either? That stuff is used
sometimes.

No, just metal-to-metal. My reaction was the thought that I'd never buy JVC
again :)

I clean the inside of my 5 TV's once a year to make sure everything
is running cool.I also check all caps for high ESR.(Thanks to Bob Parker).

Whenever I encounter an IC/Transistor that is too hot to touch I simply
bolt a larger heat sink to the original one.Makes wonders!! I even added a
small and quiet fan to cool down a reluctant vertical output.
I believe that this will prolong the life of my TV's and prevent future
failures due to excess heat. Jacques

I'm often amazed when working on TVs at the sheer amount of filth
inside. Especailly with, say, old 1980s sets, with some I've seen it
is a miracle that they have not died sooner from overheating. I have
seen scan coils coated in a carpet of fluff and circuit boards covered
over so badly that even a domestic vacuum cleaner had difficulty
sucking all the dust off.
All that must cause premature failures , insulating components,
trapping heat and preventing air circulation. Or in humid weather I
have seen sets with dust absorbing moisture and causing HV problems.

I also hate sets that have been in heavy cigarette smokers houses, or
came out of bars. That sticky tar and grime is repulsive.

Hi,

I have been servicing TVs for years. One thing I learned,
when I see a picture, I can usally tell if the picture tube is getting "soft"
(below normal emission). When I see this in TVs that are not very old,
I will check the picture settings (via menu), and sure enough, almost every
time, the "Contrast/Picture" and/or "Brightness" is turned up full or almost
full (high). I always reduce the settings and tell the customer. Most
times, this is the default setting from the factory, and you know what that
means? Shorten the life of the TV requires replacement sooner.

It's not so much to shorten the life but to make the set stand out in a
store display. Set correctly, a TV will look rather bland and faded under
bright showroom lights and in comparison to other TV's on display.

That's unusual, JVC is usually quite good, perhaps it was simply a
manufacturing defect?
