Blown resistor i need to know the value of resistor r 152 in your teac tv model eu3242st. this fried when i replaced a blown fuse, i didn't put the board back in the holder and the board arcked on the screen. could i have done more damage past the resistor. cheers steve

The treadmill have dcmd67 control board I need to know what value resistor R 19 have


I can't help you (directly) with the resistor value, but be aware that if it exploded, there is probably another bad component (such as a capacitor, transistor, and/or an SCR). Replacing only the resistor may result in the same problem, or may not even work at all due to another bad component. If you do find out the value, try putting in a resistor of the same value, but with a higher wattage rating. I once had a washing machine in which the model had a known problem with circuit boards blowing. I solved it by replacing a bad transistor and installing a higher wattage resistor that had blown up like yours. It never failed again. The way I found the value of the blown resistor is, I looked up a replacement board online, then magnified the photo, and looked at the color code on that same resistor in the photo. How I found the bad transistor is too complicated to explain in few words, but you can google the procedure. (You'll need a multi-meter at the very least; preferably _with_ a built in transistor checker. However, a _totally_ blown transistor can be found with only the resistance settings on a regular multi-meter).

Best of luck...

Model ST-21SF1. What is the value of resistor R609?


I don't know the value but if you haven't figured out why it burned you need to fix that first, usually a transistor has cooked somewhere to fry the resistor

Interior fan want work


First, check the fuse block for an open / blown fuse. You didn't provide the make & model of your car, so you'll have to find out which fuse is used for the fan. Replace any open / blown fuse found with the correct size as determined by the manual. If it still doesn't work, keep reading:

Many cars and trucks use what is called a "resistor pack" that is used to determine various preset speeds for the heater & A/C blower or fan. When you switch the fan from one speed or another, power is passed through a different value of the resistor - which changes the voltage to the fan motor. The different voltages provides different speeds.

The resistor pack is usually the problem if the fan works at one or more - but not all speeds. It can be the problem if the fan doesn't work at all either. The location of the resistor pack varies with vehicle make and model, but is often very close to the motor itself and accessible from the passenger compartment. Consulting with a employee at an auto parts store or Chilton's (or similar) auto repair manual should get you to the right spot. Resistor packs are relatively inexpensive at about $25 or less.

I hope this helps & good luck!

My 73'' mitsubishi model #wd-73738. Is flickering.


Hi!
That's a clear indication that you have a bad power supply in your TV.
If you know how to DiY...I suggest you open your TV. Locate the power supply section, it is where the end of the power plug is connected. Replace all blown or bulge or leaked capacitors with same value. That will fix your TV problem.
The hardest part is to disassembling your TV cover, cause you will need to pry off the snap in lock at the edge of your TV.

Power supply board should look like this. Examine the capacitors in the board
power%281%29.jpg2_23_2012_11_31_16_am.png

After replacing blown capacitors...it should work again.
caps%281%29%281%29.jpg

Things you will need.
1. A plastic flat end screw or any object with flat ends....to fry off the cover
2. Soldering iron.
3. Soldering lead
4. Soldering pump.
5. Flat and Philip Screw
6. Replacement capacitors (of same value with the blown one) that you can buy to any electronics store.

Or try replace light engine..if the above solution won't work..

Sony 6060F blown fuse


hello!
there is a standard procedure for proper replacement of blown fuse: CRT TVs: unplug degaussing coil, replace blown fuse with 2amp fuse and turn on the set. If it works, reconnect degaussing coil, replace the fuse with correct value(5-8) amp, depends on model(see fuse note next to holder). Enjoy the show! If in a process of replacing the blown fuse with 2amp w/o degaussing coil it blows again, forget about the next step. Set need repair. It could be an easy one, replacing 1 or 2 shorted diodes or bridge rectifier, but could be real piece of work if the power supply got "fried". If your knowledge won't go further, than fuse replacement, I'd recommend local TV repair shop.
good luck,
Alex.

No picture.


Your set may be fried, or at least the power supply or fuse(s). If you feel like you could work on it, open up the power supply (if it's outside of the TV) or open the set itself (if it's an internal power supply). Look for the fuse(s) (the little glass tubes) and pull them out and check them one at a time (in case they're different values and you forget which one went where). If any of them have a broken filament (the little wire inside of them), especially if they have any black soot or brown-ish stuff in them, then the fuse is blown and needs to be replaced with an identical value fuse.
DO NOT REPLACE FUSES WITH DIFFERENT VALUE ONES. I can never stress that enough. On the metal band, it says the current it allows. Match it up with another fuse (it'll be the same size and everything) and bam, that could fix your problem.
If it's not a fuse, then perhaps the filter capacitors in the power supply are shot. If you don't know what they look like; they're cylinders that are usually placed right by where the cord comes into the supply. If any of them have a hole or any black or brown residue around the bottoms, then they're blown and need to be replaced with identical ones (or at least the same capacitance and max voltage). Be careful with capacitors. If they're put in the wrong way, are shorting out against anything else, or have a max voltage that's too low, they can blow immediately and sometimes violently. I've seen them blow out and have electricity arcing across them, frying everything around it.

On the circuit, one of the resistors got blown up


U can see one or two bands of the colors of the resistor right?Compare it to a couple resistors beside it or around in the board.U should know and determine it values.
