If you wish to get some details check the site linked here. If the voltage is absent check the feeder resistor if any. Replace the horizontal scan output transistor. Check the LOT (Line Output Transformer) too for damage. Check and replace damaged component/s at its horizontal scan output section circuit. If this frequency is found higher than normal, The main IC jungle should be suspected.Īnyway, go forward after checking this frequency. It should be around 15625HZ, with no signal.

I have used a base voltage of 5V and a value of 1K as current limiting resistor. In actual circuit modifications might be required. To make things simple, I have shown a simplified circuit to make a transistor as switch. The value for this resistor can be calculated using the formula As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging.
However one important thing to notice is the Base resistor a.k.a current limiting resistor.
This transistor will make it forward biased and thus closes the connection between collector and emitter. The Base-Emitter voltage of this transistor is 6V so you just have to supply this voltage across the base and emitter of the transistor to induce a base current into the transistor. This transistor like all can be used either as a switch or as an amplifier.
So if you looking for an NPN transistor that could switch loads of higher current, then 2N2222A might the right choice for your project. 2N2222A can allow collector current upto 800mA and also has power dissipation of 652mW which can be used to drive larger loads than compared with BC547. But there are two important features that distinguish both. The 2N2222A transistor is very much similar to the commonly used NPN transistor BC547. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around 660 mV. This stage is called Saturation Region and the typical voltage allowed across the Collector-Emitter (V CE) or Base-Emitter (V BE) could be 200 and 900 mV respectively. When this transistor is fully biased, then it can allow a maximum of 800mA to flow across the collector and emitter. To bias a transistor we have to supply current to base pin, this current (I B) should be limited to 5mA. The maximum amount of current that could flow through the Collector pin is 800mA, hence we cannot connect loads that consume more than 800mA using this transistor. 2N2222A has a gain value of 110 to 800, this value determines the amplification capacity of the transistor. 2N2907(PNP), 2N3904(PNP), 2N3906 (PNP), BC637, S9014, BC148, 2N4403, MPS2222, PN2222, KN2222, KTN2222ĢN2222A is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin.
