Maytag MDB7100AWB dishwasher board burnt resister


first of all they wont give you any specs on circuit boards for most appliances,they just want you to replace the board besides that,if a resistor burnt its because there was a heavy current draw on another component that is supplied by this resistor and you would need to locate this defective part such as a motor/solenoid/heater or the new resistor will end up in the same manner,the 2 oozing parts are probably capacitors leaking their die-electric compound from heat and age so they are in need of replacement too,you might go online and ask somebody with a board like yours for the part values,but still you need to find the main problem for the problem on the board first

Pioneer sa-1050 2 burnt resistors, cannot read


where exactly are these resistors located? any idea about the circuit board resistor numbers? sometimes burnt resistors do not go completely bad and is still possible to measure their values. why not take them out and try measuring their values. otherwise u have to b very specific about the rsistor numbers

I got this one dead. There is a burnt resistor on the main circuit board ( the one with the on/off sw). Would anyone know what value it could be.


Hello,
You can determine the resistors value by reading the color code bands that are marked on it. The following picture is an example of the color codes and there values.

To show you how to read the color codes on a resistor, I am including a link to a video that will explain how to do this easier than I could probably explain it.

I hope this helps you in solving the problem. If you need further assistance please feel free to ask.

If you would not mind, please rate my help. I would greatly appreciate it. Thank You

I have no power getting into my dvd recorder. would it be the power supply to the unit is burnt out.


If you not getting any indicator at all, then the power supply is dead, if you get some indicator light and that all it does, then the 5v standby voltage circuit is OK but not the main power section. Look for bad filter capacitors that will have bulging tops.

How do I find the value of a resistor if it is burnt?


sometimes the component is listed on the circuit board in it's value where it is mounted.
can you read the color bands? if not than a schematic will list it.

Y-SUS board: How to determine if it's fried?


Your solid green "resistor" is probably a fuse and will have an amp rating stamped on it, if you can read it with a magnifying glass. Before you replace that you need to find out what else on the board or somewhere else in the TV is blowing the fuse. Resistors have bands to denote their value unless it is a large power resistor and the value is written on it.

There is usually an identical resistor somewhere else on the circuit board, so if you cannot read the colors of the burnt one, you can read the colors from an identical resistor on the same board. If you just replace the resistor, it will probably just burn out again or damage another component, you have to find the cause of the resistor burning out, most likely an electrolytic capacitor failing. Look for bloated or seeping capacitors and replace those as well. Also look for broken or burnt toroid coils.

Magnavox resistor problem


The CRT board is the one that connects to the back of the CRT.
Follow the 200VDC line to locate the burnt resistor, is normally a low value fuse resistor.
