Did this fix a year ago and my amp still works... i love this thing with the electro-voice evi-28 speakers and image dynamics 15'' subs, this is a crazy clean loud lifelike sound setup. I never thought i would own a system this nice sounding. Ohh i found the amp in the trash....

They will be value of 10 ohms or less in the secondary power supply attached to the front assembly

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...

Lightning damage


Replace the parts with the original ones, a .5 ohm difference on a resistor on the video circuits will cause the unit not to work correctly.

Integra 7.8 display bad


The bad resistor is on the ps board that drives the display, well on mine at least. The resistor is supposed to be 10 ohms at 1/8 watt "i think" i replaced it with a 1/2 watt resistor. Either way its R9310. the board is right behind the display on the right side just behind the volume knob. when open and looking from the back you see it just fine. it's not hard to get out. fairly simple to fix. integra-7-8-display-bad-otccdugj0mk41z1tpuysbqy4-5-0.jpg integra-7-8-display-bad-otccdugj0mk41z1tpuysbqy4-5-2.jpg

Digital display not working


Do you know if your display is the VFD type (usually lights-up greenish-blue or amber on black,) or LCD (usually has a backlit backdrop with either black or colored digits)? Most are the VFD type and can dim over-time due to a resistor gradually changing value. Look on the board near the display, and see if a resistor appears to have gotten too-hot. I've repaired many displays on VCRs that have exhibited the same symptom. Hope it helps!

How do you fix the color to a model 43fdx11b hitachi


Hello!you mean: colors out of convergence? nothing you can do about that, unless you replace 2 convergence amplifiers I.C. chips, plus all those burned 1 watt low ohms resistors with exact values, which only could be obtained via service manual or schematics. After resistor is burned, there is no way to read color code properly, due to partial evaporation of pigments. this is a "pro" job. If you try or tried, already to converge those "stubborn" crosses, there is more to do, even after you removed and replaced two 20 pin I.C. chips, soldered dead into sweep module, plus located and replaced resistors with precise values, you need to get your settings back to normal, by going into "factory service mode' or, at least into "convergence alignment" menu and fight with those crosses!Don't forget the white "****"! Otherwise, you will be re-servicing your set all over after 30 days of usage.good luck,Alex.

Sony resistor values?


It is recommended to use the same value due to the function of the resistors and their values.
A lower value will let the current flow a bit faster and the higher value will slow it down according to their design.
Try installing the same value of 220 ohms.
Hope this helps.

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.

Need value for part R14109


R14109=750ohms 5% 1/4w (Resistor(750r5%.25W/R14109/179317) There is much more likely wrong with the TV. Resistor don't normally burn out with help, say, without a failing flyback transformer and possibly taking a transistor or two with it. If you need the manual, go to http://www.samswebsite.com/photofact/pf_search.asp and type in "F31317" into the search field, you will several listings. If you decide to replace it yourself, here's some more part numbers in case you need them.

Display not working.


This Problem needs an expert Technician: Your problem is due to a missing Voltage around -30 volts that supplies the screen Processor. It could be an open low value resistor or defective switching transistor. Good Luck Toufic Malek
