What is the value of resistor 601


600 ohms

A resistor with a number code instead of a letter code is a SMD:
Surface Mount Device. You might have searched for SMD resistor code and got some hits.
The system for SMD resistors is:
1st value-2nd value-multiplier
6 - 0 - 1 following zero
= 600 or 600 ohms
603 would be 60,000 Ohms or 60k
6 - 0 - 3 following zeros

While replacing the caps on on the LCT32HA36 power supply i noticed a corroded solder joint the Z3 diode. When i attempted to re-solder it the trace came off the circuit board and I lost the R3XX surface...


The resistors are color coded.There should be 3 bands which are slightly separate from the 4th band.The 4th band is usually gold,silver,or i forget the third color which is actaually a %.The top 3 bands can tell me the value of the resistor.If you tell me all 4 colors I should be able to tell you the value,with the gold/silver/whatever as the fourth.The first one should be right near the end or top.The only 1 problem will be trying to determine the wattage rating but is usually very small within a circuit.Greg

Black Screen One resistor is found Blown inside BWB but value unknown ! Please help !


Depending on the resistor, the values for a resistor is color coded, meaning that there are a couple of lines of colors and each color line represents a value. Do a google on Resistor coloring chart and you might find your answer. If the resistor is a surface mount one and very tiny, you might be out of luck as these are too small for the manufacturer to print the part number on. Only the manufacturer has that part number and can be very hard for you to contact them about.

Amp repair advice


check on the board to see if there is a resistor that looks similar, 90% of amps amps are matched in there design, meaning the left side is usally a carbon copy of the right, so if you look at one side and there is a resistor that looks like it's in the same spot on the other side, good chance thats the same one, read the colors off the one thats not burnt up. resistors come in different wattages,1/8,1/4 1/2 up to 10 watts, each wattage is a different size, most of the ones you see in the amp are 1/4 watt but some are 1/2 and 1/8. some on the output are 2 to 5 watt, but those are generally 10-18 mm in length, they are big ones you cant miss those. so once you get the color code, read the colors, ex red,gree,brown,last line is either silver or gold, that will tell you the resitor value. then google resistor color codes and then you can match the color sequence with the value codes, and that will tell you the value you need in ohms but then you have to get the size 1/4 watt resistors are generally about 6 mm in legnth, im measuring the actual part of the resistor not including the metal leads, just the body, so if its larger its probally a 1/2 watt if smaller its an 1/8 watt, 1/8 watt are about 4 mm. now go buy the resistor, but you might find it that tough, if its a common value radio shack might have it, but resistors are so cheap, pennies for a handful, good luck on your search.

Dead set


Try taking out battery and plug in power. If it works, battery is faulty.
If not, try taking out your hard disk plug in power, if it works, hard disk is faulty.Try taking out memory card, if there's a sound, memory card faulty. If no sound, it's your motherboard that is causing the error.

Note: If machine is under warranty no need to pay for the repairs.

Motherboard resistors RV2 and RV3


RV1, RV2, and RV3 are capacitors. They're actually dark green in color because they're made primarily for automotive applications. If you remove one and measure it with a capacitance meter you can find the value. On a 600M/D600 I believe they're 150pF, but on other boards they may be 100pF. Digikey part numbers for them are 490-4962-1-ND for the 100pF, or 490-4767-1-ND for the 150pF. Good luck!

Battery not charging. Power Adapter ok


DC jack issue usually.

Or a bad repair- many techs not skilled enough will wind up losing RV1,RV2 or RV3 MOV. this is so small that I had documented it on my site. The chip has no values printed on them, and are hard to find "Close-Up"

But fear not, most of the times it is simply a DC jack replacement. They are about $8 on ebay. And only a skilled tech should replace it.

How they fail?
It is a circular tri-axial ring inside, the leaf type contacts become fatigued and no longer pick up power. Or the center contacts become fatigued.

OR the jack left the factory with insufficient solder and repeated use caused it to crack.

Toshiba 57H82 resistor value???


When I get to work in a few hours, I will get the value for you.
Yes,you can use a regular 1/4 watt resistor and you might be
able to measure the value of it's twin in the other IC circuit....T.
