How to measure the voltage on TV

Voltage measured on DC scale, black cable multitester / avometer put on a negative path or can be slipped on the silver wire in the tube that is not disposable wrapping.

Next, measure the voltages are available:
  • For 180v voltage can be measured on the positive pin elco (10uf/250v) in PCB RGB tube.stick pin red wire multitester
d3f355a.jpg
  • Voltage 110v for TVs 14 "-21" and 130v for 25 "-29" in the B + FlyBack Transformer (FBT), find the path there is elco 100uf/160volt. measure on a positive foot elco.
  • For 12volt voltage, please measure at the foot of the right edge of IC 7812.
534aece.jpg
  1. For voltage 5V, please measure the right foot of IC 7805.
  2. For voltage 33v, please search at the foot of VT in tuner.
  3. To measure 90v-300v, scale use DCV 250.
  4. To measure the 12v-40v, use a scale of 50 DCV
  5. To measure the voltage of 1V-9v, 10 DCV-scale use.
  6. How to measure the voltage on the yoke and in plyback is;
    • From the yoke horizontal = Fcc 110v DC, 1000 V. AC voltage can be removed with a red plug in output and in use as dB meter.
    • From the yoke pertikal 24 DC current model, except for disposable coupling C = 1 / 2 Fcc. While it could be IC 120V AC (with dB meter)
    • At Fcc FBT kolector; 110v DC, AC voltage = 1000 V..
    • At Fcc FBT filement / heater = 5V-5, 5V AC.
    • In the FBT 20-32k anode voltage V measured with 40kv HV probe is added to the multitester 1000 V. DC.
    • Voltage others depending on model and type of TV. 180v out there (for RGB) directly from the regulators, transformers, Video Amp taken from FBT.
    • There are 24V and 46v vertical FBT, also 12-18V depending on brand and type.
    • Voltage 600 V DC and focus around the screen 400v DC.

    Thus tip n trick from me (AGUS YUSTIARA ), hopefully useful.

How do I use this adapter in the US with 220 voltage

is it an 220volt ac - dc adapter you could buy a 110V AC to DC adapter with the same DC Voltage and current rating
or you could buy a 110V to 220 Volt adapter
http://www.banggood.com/110V-to-220V-and-220V-to-110V-Voltage-Transformer-Converter-100W-p-938645.html?currency=AUD&refreshTmp=1&utm_source=google&utm_medium=shopping&utm_content=lola&utm_campaign=Beauty-AU&gclid=CIG68_Gl2cICFVcJvAod7GgArw
be careful with switch settings
http://www.ebay.com/bhp/transformer-110v-to-220v


please be aware if timing is required or electrical motors this could be a problem as usa is 60Hz and your appliciance may be designed to run at 50 Hz frequency
there are devices that can convert freq from 60hz to 50 hz

DOES THE FORD TAURUS HAVE A VOLTAGE REGULATOR

Every car ever made has a voltage regulator

The alternator is just that-- AC Current that is rectified
to DC-- to run the car & charge the battery

Just about every car for the last 40 years has the
regulator inside the alt

How it is controlled varies from manufacture,make,
model,year,etc

You can not charge a defective battery

You may have external issues that provide
regulator control,even a bad ignition sw on
some cars,or module control of regulator

Need a wiring diagram & a good amount of
knowledge to resolve your current problem

I cant plug my 120v input vamp2 power adapter into a 110v output voltage regulator its dont works

I don't understand why you are plugging this into a 110 volt regulator.. If by chance you are trying to run this from 220 volt power, you DO NOT use a regulator or a converter intended to run hair driers and appliances. You need to use a step-down transformer from 220 to 110 or 240 to 120.
The V\Amp2 is a switching regulator and it will NOT like to be run from another switching regulator such as found in those cheap appliance type convertors.

Here is the type you need: http://www.world-import.com/tc-100a.htm

When we will give the power to TV, fuse & R502 location resistor burn.

damage can be ascertained from the power regulator, you can check the transistor / STR power regulator, and Diode Bridge (AC-DC), check the Positive and Negative on Elco 220/450 volt power regulator, is there a short circuit? if no, probably from before entering the diode, it can be from thermistor. Hopefully help

Powermate PM0496500.02 No voltage output

Here is a simple test to check field and other wiring. With engine off apply 12v ac 1 amp to 110v outlet plug on generator. This will energize the field windings and should cause the armature to produce dc voltage at the brushes and produce a nice magnet. If there is a short in the field or broken wire or shorted capacitor there will be no dc reading at the brushes. . This test is the opposite of what actually occurs when the engine is running. That is the armature produces a magnet fed thru the windings, regulator and brushes. If dc voltage is present at the burshes, remove 12v ac and start engine to check for output. enjoy
