You can get the value of this resistor from the circuit diagram of your model TV.
Usually a burnt resistor is caused by some other component failing that is connected to the resistor.

Hey boss. Just follow this guide and replace with a resistor that matches the value and tolerance. You have a 5 Band resistor, follow the guild and you should be good. Click here for a chart to help you identify the values.

Radio Shack Multimeter, 22-168a, shunt resistor value????


Go to the Radio Shack site and you may with the model number find a schematic or you can email/contact them for the value of the resistor.

I predict it is a precision value and type you will have to get from them if available.

PS: you posted in wrong catagory as this is TV section.

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...

Resistor burned on my Grandmother's Emerson model NR303TT


Hello Gio, Hi, a burned resistor is usually caused by a shorted part like a semiconductor or regulator, there are two things you should do, find the value of the resistor and what caused the resistor to burned, for the Resistor, the value is usually written on the board, If not you can find the value on schematics diagram (which is usually hard to find, but if you have one, fine), and on the same working model (very remote a possibility). IF this are not available, you now need the assistance of a technician.

Burned resistor, need value for replacement


I re-drew the schematics from the PCB-layout and did some backward engineering to determine the resistor value. The machine is now again in excellent working order.

Burned resistor... no clue what is its value


brYze,

take a look and get the resistor number printed on the pcb. i might be able to give you what you're asking for.

Burn resistor


if its a 4 band resistor, use the following calculator...

if the resistor is a 5 band, use the following link....

Re:tv


Hi Redd, You might have better luck posting this under Sharp TVs: http://www.fixya.com/support/sharp/standard_televisions The black lines at the top of the screen are usually an indication of a problem with the vertical output section. It's often bad electrolytic capacitors, the vertical IC, or both. That's apparently not a US model, so it will be hard to find the values but you could contact Sharp Philippines: SHARP (PHILS.) CORPORATION [Philippines] Km.23 West Service Road, South Superhighway, Alabang, Muntinlupa,Metro Manila, Philippines Tel: 63-2-842-1371 Fax: 63-2-842-0530 Service Center Tel: 63-2-807-4991/4992 Fax: 63-2-807-0388 Home Page: http://www.sharp.ph/ Good luck.
