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?

HP does not publish schematics.
what we do is buy a new one. every time.

WHAT IS THE VALUE OF RESISTOR R10 IN THE CIRCUIT BOARD?


Look at the color bands, they will determine the value. Last band color is the precision value of the resistor. You can find the color band values on many websites. The size of it tells you the wattage raring.

Power supply damaged, Can I replace it with any other model power supply?


A standard ATX PS won't fit in your low profile case. The plug types can be different too. Usually there's a schematic with a PS that describes the wire color of each voltage. So you could conceivably shove the pins out of one PS plugs and insert them into the different plug, or solder the wires to the correct pins, and leave the PS outside of the case.

What is the brand name and model number to your TV? Provide more details please. To give you the proper value of that resistor, i must get its position or part number. for more information go to http://electronicshelponline.blogspot.com/. It has schematic diagrams to many popular TVs' power supply. Hopes, it might help you.

Samsung home-theater model no# HT-E330K, power supply resistor RA805 completely burnt can't see the value of the resistor. Pls help with the value of the resistor


This may sound like a lazy answer but without a schematic, its going to be tough. Perhaps you know someone...or maybe there is someone here who has the same unit who wouldn't mind opening it up to get the value. Good luck.

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

Missing part


Charger does't connect to DVD player.

Connects to battery. Built your own, Radio Shack, female to male jack, power supply from anything handy or spend $2 at thrift shop, $2 multimeter (Harbor Freight, Cheapo), junk variable resistor (pot).

7.4--8 V adjust. Or, get fixed value resistor dependent on PS voltage.

Charge anything,

And power supply for DVD house current.

The best way is to get one off ebay by part number. Take it apart and write them down. Then order the resistors and you will have 2. Then you can either sell the other one back or keep it. You cant lose if you have electronics skills.
