I have a resistor problem in sanyo please help me. location R617..the problem is the resistor of this tv has change value and can't find the the sign color of the resistor because it the resistor will burn.

In order to answer that, one would need to know the manufacturer's name and model number to the CRT you're trying to repair- in order to look up the schematic for that particular unit...and the printed circuit board number that the resistor 617 is positioned on...
Try an online search engine to locate the service/repair manual for your t.v, or go to a local t.v. / electronics repair shop; they'll be able to ID the resistor you'll need.
it's very difficult to give the exact value of that resistor.,but i can give some tips to find the value of the said resistor .( find how the resistor works, it is a dropping or fusable? if fusable used .47 or 1 ohm resistor if it is a dropping resistor you should make a trial and error .from 100k,10k or 1k.
Vcc is on Pin 6 of the vert. output IC so you can trace that back to it's feed resistor (not sure the location number but you can find it easily by following the circuit trace).
Depending on what your problem is you may need to replace some
electrolytic capacitors as well. Follow pin 7(pump up) back to it's electrolytic
cap. and look for swelling or bulging. Look for other bulged capacitors in the vertical section. You may also identify a bad resistor by a discolored look but not always, if in doubt meter it. Let me know if you need some more info.
Yes it can be replaced if you know the value in ohms and watts and you can use a soldering iron. Resistors normally blow because of excessive current flow sometimes caused by downstream or upstream components that have shorted out or are being overloaded beyond what they are rated at. Sometimes (but rarely) they just blow for no reason.

There is much more likely wrong with the TV. Resistor don't normally burn out with help, say, without a failing flyback transformer and possibly taking a transistor or two with it.
If you need the manual, go to
and type in "F31317" into the search field, you will several listings.
If you decide to replace it yourself, here's some more part numbers in case you need them.
Necessary parts: Transistor(Q14401)
Main Voltage regulator Q14101
Resistor R14109 open.
Research indicated the flyback transformer most probably bad
Hope this helps you.
