    Old RCA CRT Console TV Repair

    Harald Kapp pretty-much covered the first things to do. My added input is to stay away from the red 'anode' cable that plugs in the back top of the picture tube itself and runs down to the flyback transformer. The picture tube acts as it's own high voltage 'capacitor'. Even when the TV is...

    Electrostatic air cleaner

    I'd check with a furnace/air conditioning supply place. Maybe an appliance repair supplier.

    Weight sensors

    daveen told you what you're looking for. I would start Googleing load cell manufacturers and look at their application information. That would be your best source. You'll find exactly what you're looking for, for your needs.

    Help, I need to identify burnt chip.

    Try Googleing the model number to see if you can find a free (or cheap) schematic so you can identify the burned chip. Maybe even a schematic on the manufacturer's website(?)

    creative 2.1 speaker system repair..

    Not much information to work with here. I used to repair my kid's Creative speakers for their computers. Most of the problems I had with them was damage to the power supply sections. Secondary damage was often the power output transistors. Do you have any electronic troubleshooting/repair...

    American Electronic to Australian

    I've tried to stay out of this, but I'll jump in here with my input. I've used US turntables (60Hz) in overseas (50Hz) systems. The turntable spins slower at 50 Hz. As davenn has tried repeatedly to help with this, I'm reiterate that along with the voltage difference, the 50Hz/60Hz difference...

    CO and CO² Electronic Flue Gas Analyser

    I'm sure we'd like to help. The problem is that we don't know the original circuit of your analyzer, and we don't know the modification using MOSFETs that is supposed to allow the analyzer to give you CO2 readings. You intend to send the instrument in for recalibration. With those results, you...

    Wanted: RCA VCR (VR676HF) power cord

    Show us a picture, if you can, of the socket on the recorder, and we can tell you what type of cord you'll need.

    CO and CO² Electronic Flue Gas Analyser

    Your MOSFET/FET video explains how they work. They are electronic components. They have nothing to do (themselves) with the detection of CO/CO2. Your circuit apparently uses them in the electronic circuitry that is designed to detect CO/CO2. If there is an improvement in your analyzer using...

    Microwave acts wrongly not working properly!

    If it works, nothing is broken. It could have been as simple as a bug shorting-out a circuit in the processing controller, and when the short was no longer there, everything works fine again. (ANY CLEANING YOU DO, MAKE SURE THE MICROWAVE IS UNPLUGGED FROM THE WALL FIRST!) If you try cleaning it...

    Port On The Back Of Automotive Oscilloscope

    Did you get an owner's manual with this buy, or can you contact the seller to ask what it's for? If it's 'new', new. I would assume it has a manufacturer's description of it in a manual or on-line. If it's 'new' to you, but owned by somebody else previously, they may have modified it for some...

    Flourescent light issue

    Yes, it sounds like the socket may have a problem, or the bulb is not screwed-in all the way.

    Need Help Identifying Collector, Emitter, and Base

    Translation in case you need it: (Google FET) FET = Field Effect Transistor

    How to trigger solenoid with very low current?

    Can you supply the information Alec_t asked for? That would help. In your situation, without knowing your application, you are on the right track considering using a relay to control a required current to the solenoid. HOWEVER, the only thing a relay does, is apply some other power supply...

    Microwave acts wrongly not working properly!

    Do not try to fix this if it goes bad again. You have just enough knowledge to be dangerous. The magnetron and capacitors in microwaves can kill you. Bugs can short electronic circuits. Get them all out of the electronics and into the cooking area. THEN turn the microwave on. (Duh. Thanks...

    Can you help me with capacitor's code?

    4V should work fine.

    did i short out or solder incorrectly on ps3 superslim ?help

    You should probably show a clear picture of what you soldered and let us take a look at it.

    What is the real name of this part?

    davenn's got a good point. I'd be more concerned about he TL072 Op Amp (which is also pretty cheap), than the caps themselves. What is your fault? What is the problem you're seeing? The best way to try to search for caps, is to try to get a print copy, or actually access the vendor's catalog...

    Fixing an HP3455A multimeter

    I'm sure management at the companies that helped supply your needs, were happy to rid themselves of their surplus items. The 'big picture' after all for management, is NEW sales.
