Help to ID blown resistor
 

A resistor on my Vizio LCD tv's power supply just blew.
It is not color coded, it is grey with black writing as you can see in the
attachment.
The writting looks like "F0457" "0-1 ohm" "R ?? 2J"
Any help IDing it would be much appreciated,
or send me to another newsgroup or website that might help.

The power supply maker is Delta Electronics Inc, Model: DPS-210EP A rev:00, S/N
ADDD0421008022

The TV is a Vizio L30, date of mfg: sept 2004

0.1 ohm 1/2 watt fusible flameproof.

Yes, but the true problem is that whatever caused the fusable resistor to
"blow" will cause its replacement to blow also unless fixed.

Since the value is burned away, you'll need a schematic
to find out what the value needs to be. It's not determined
by looks or shape or size.

I didn't notice that this might be the same resistor in
the three shots.. But, if it is, then it's a 1/10 ohm resistor
as labeled.

Mouser and Digikey only had .47 ohm, so I got 10 of them.
If one blows, I'll parallel 2 or 3, and if those also go, I'll just get a new
power supply, there are same model # but higher revision numbers for
$110.
Thanks for the help.

An update.

The fusible resistors I installed blew, even with 2/3 in parallel. And it is
assumed that it is either a relay or the transformer, which I did not want to
waste my time trying to trance the prob, especially if I can't find a component
to replace it(right size and all).

So I ordered a PS with a revision # near mine (from a place that takes parts out
of tvs with broken screens and stuff), got it and it works fine now.
