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
- 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.
- For voltage 5V, please measure the right foot of IC 7805.
- For voltage 33v, please search at the foot of VT in tuner.
- To measure 90v-300v, scale use DCV 250.
- To measure the 12v-40v, use a scale of 50 DCV
- To measure the voltage of 1V-9v, 10 DCV-scale use.
- 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.
