Radiators adversely affecting CRTs?

[[email protected]]

OK so I've only just started to put this together..

About a year ago my TV (28" Sony Trinitron) started to lose picture
completely every 5-20 seconds when displaying bright images, so I
thought right, it's quite old (1997 ish?) so maybe it's just on the way
out. Thought nothing of it other than "I need to buy a new TV"

2 weeks ago I rearranged this room, and now my computer monitor (22"
Sun Microsystems X7149A CRT) is about 2 feet away from where the TV is.
Today I've noticed the EXACT same symptons my TV started exhibiting
about a year ago, although a lot less frequent. The screen loses
picture (just goes black) for about half a second, approximately once
an hour. Which is how the TV started off, and got worse kinda fast.

Now, I thought maybe it's because I have hi-fi speakers both by the TV
and my monitor. (Magnetism) But then I thought it can't be that because
I've had hi-fi speakers next to my monitor (this one and my previous
one) for about 7 years. So I thought about the other common
factors..the only thing I can think of is there's a radiator in this
corner of the room, which the monitor and TV are equal distance from
(about 1.5 feet) Does heat have this sort of effect on CRTs? I'd kinda
like this screen not to die the death that my TV is undergoing..

Any ideas? Even better any ideas how to FIX my TV? lol (that's probably
hoping for too much )

By put this together I meant, realise that the two may have something
in common (since they're in similar places). Just thought I'd make that
clear.

Hi!

2 weeks ago I rearranged this room, and now my computer monitor (22"
Sun Microsystems X7149A CRT) is about 2 feet away from where the TV is.
Today I've noticed the EXACT same symptons my TV started exhibiting
about a year ago, although a lot less frequent. The screen loses
picture (just goes black) for about half a second, approximately once
an hour. Which is how the TV started off, and got worse kinda fast.

So I thought about the other common
factors..the only thing I can think of is there's a radiator in this
corner of the room,

What type of radiator is this? Is it an electric type or is it connected to
a boiler of some kind?

Heat could certainly be a concern here, but I wouldn't think it could such
sudden malfunctions from 1.5 feet away. Can you be comfortable that far from
the radiator?

I'd hazard a guess that you've plugged the monitor into the same outlet that
the TV was plugged into. If so, I'd look there for a problem...such as low,
high or unstable voltage. Get a good voltage meter or call an electrician to
check the outlet. Find out what else may be on that circuit...is there
anything that pulls a large amount of current and might cycle on or off
about hourly?

If your TV is still working at all and you want to have it fixed, take it to
a repair shop promptly. Any repairs that must be done to it will be less
expensive while the set is still "working". Waiting until it fails entirely
will result in a much larger repair bill. As for your monitor, I'd move it
away from that outlet (use an extension cord and plug it in somewhere else?)
and see what happens.

I don't think the heat will affect a crt to any degree unless its hot enough
to warp the shadow mask, but the heat could dry out the electrolytic caps in
the PSU which could explain the symptoms. Probably a cheap enough fix if you
get it done now.

Now, with that power comment you may just have hit the nail on the
head..everything in this room and I mean -everything- runs from a
single outlet, since this house is quite old they didn't really need
more than 1 outlet when it was built.. As for the heat output on the
radiator it's not very hot in the day its an "Economy 7" storage
heater, turns on between 1 am and 7am and slowly releases heat
throughout the day.

I'd say it's either a fault with the power outlet there or a freaky
coincidence.

Could be there's some heavy power drain for a second or so on that
line. Do you have a fridge or air conditioner plugged into that outlet
or line?

Define "everything"...how many and what kind of devices run from this
outlet?

It sounds overloaded to me...especially if your home is quite old. If the
wiring in your home is in otherwise good shape, you might consider expanding
the wiring and number of circuits you have. Be careful not to overload the
capacity of the electrical system.

If the wiring is not in such good shape, you might look into renovating it
or upgrading the system entirely. Old wiring can be perfectly serviceable,
but sometimes it needs a little help, especially after many years of
service.

In any case, you should do something. Electrical fires are not fun.

As for the heat output on the
radiator it's not very hot in the day its an "Economy 7" storage
heater, turns on between 1 am and 7am and slowly releases heat
throughout the day.

Hmmm...still not sure what kind it is, but I'd be surprised if the heat
coming from it was the problem. If it is electrical, then it could be
overloading something.

Well I've determined that it's not the power (I think) by using an
extension cord from downstairs (it's on a separate ring) and the
problem's still the same. As for the overloading issue, I've been
running all this for about 5 years from that socket lol, so it's
probably not that. Running from that single socket is: TV, Computer,
Monitor, 2 Stereos, Lamp, DVD Player, PS2, Phone Charger, iPod Charger,
Guitar Amplifier. Rarely if not never, used all at once though. I think
the TV's just broken, as it's quite old (1998 ish?) Only way to stop it
losing picture is to turn the brightness right down, making the picture
almost unwatchable in some situations. I'm guessing it's either not
fixable, or would be rather expensive. Should I just junk it and get a
new one? (Not that I can afford that right now, probably gonna get a
plasma/lcd when I get a new TV.
