I would fit the same type, unless the schematic shows a change, which clearly it doesn't. However I would be surprised if R42 burnt up alone! Look at the schematic, is R42 linked to any other transistor or part? If so check them if you can.
By the way is R42 a fuseable resistor, for example is the symbol on the schematic or on PC board different to most other resistors?

Value of R065 on power supply module of the RX-884V


value not cost $ but a resistor is it to hard to say resistor.?
OHMS and color bands all that is easy but no VALUE eve guessed
and if burned up and my guess it did (not said)
and guess what even if you had a correct resistor
it too will burn up, due to other part is shorted 99% chance.


see?

I want talkback on cobra 18 WX ST


Probably to Chassis Ground. You may want to experiment with the resistor value if you use a power mic. A 100 Ohm resister may be too low a value and cause audio feedback if you do use a power mic.

I need to know the value of the Resistor "R1" in


Let us use a bit of logic to resolve this... I have an Axiom but it would be a lot of screws to take out to get to the part... so let us think about this. The resistor value starts with a "1" and we know it is 5% tolerance (gold). we know the resistor burnt up with likely 5 volts on it... Value could be 1000 ohms, however the voltages present (12 volts max) would NOT have burned up a resistor of 1000 ohms. The USB area is mostly 5 volts and across 100 ohms is only a quarter watt... not enough to really burn up a resistor... First thing is to MEASURE that the resistor s open... in spite of being burned, it MAY still be OK... these resistors now usually either open or remain close to their value. The resistor ALSO may be a fusible resistor intended to act as a fuse... Is the resistor open or not? is it near a resistance with a "1" as the first digit? If it is not open I suspect it is not all of the problem. In that case, look for a burned circuit trace on the board. If it is open, then MEASURE the voltage across the resistor with the power applied. If you find 5 volts, then it MIGHT be a 10 ohm used to limit the USB current to 500ma. Get back to me with your findings... I have unraveled many of these things...

I Need values of resisters R-82 and R-85. They feed plus and minus voltage to power amps. amps shorted and burned resistors. The amp is a subwoofer amp in a B & W model DM605 s2 speaker. Any help would...


If the resistors were blown, the power amp which is either transistors or an amplifier package has been shorted out. The resistors are very low resistance, and used really as slow blowing fuse. The value is probably a fraction of an ohm (eg. point two ohms)

I see only horizontal line on TV Samsung CK-5339ZB


h/line is due to vertical section failure. 1 reduce brightness as you will get h/line due to vertical failure. 2 check v/section for loose contact or yoke connection. 3 check supply to vertical section. 4 check associated parts in v.section 5 at last check for vertical ic. resistor R410 CONNECTED TO high voltage transformator T444 is low value resistor. .5ohm to 10 ohm. it burnt again due to short cht in vertical mainly due to ic. hope this will help. as per schematic diagram go to www.serviceinfo.com
