Have you tried contacting them for a schematic yet?

Hello.

A friend of mine found out I sort of know how to repair televisions
so I'm
fixing his. It has a blown resistor in the power supply section of
the
circuit board. The TV is a Citizen 25", model number JCTV3413A.
There is
also a number on the printed circuit board TMX456A. The tube was
made by
Orion and is model number A63AHC26X. The TV was purchased and is
used in
Alberta Canada. The blown resistor is in the Power section of the
circuit
board and is R515. I can't identify the resistor as the colour code
was
burned away and I haven't been able to source a schematic diagram.
Can
anybody help me with identifying this part? It is probably between 1
and 5
watts. It may be 1.5 ohms. Also any theories on why the resistor
may have
cooked? I didn't want to start troubleshooting until I was sure I
could get
a replacement resistor, so I haven't looked yet. However if you have
some
clues you could offer I would appreciate that.

One other thing I noticed. There is a large 20 watt resistor that
actually
sits more or less overtop of the resistor which burned it's value is
180
ohms. I noticed it's ceramic casing has a crack in it. I tested it
and it
still has the proper value (or at least it does when it is cold).
I'm going
to replace it as well because they are cheap. Might this have
something to
do with R515 burning. The PCB is ambiguous but it might be R506.

Thank you for any help you may be able to offer.
