Davidson www. Last but not least, thanks a lot to Michael B. Servicing consumer electronic products can be a lot of fun if you let it be. Just as in solving a great murder mystery, the smart detective must have the skill, desire, and ability to find the culprit, so also the electronics technician must take the symptom and isolate, locate, remove, and replace the defective part. The anticipation of locating a dead, open, or leaky component is like finding a needle in a haystack, so to speak.
Your heart beats a little faster as you zoom in on the suspected part. Then great disappointment sets in when the suspected component is not the guilty party. So you try once again. Now victory is in sight. However, if you can repair and service the electronic chassis without a schematic, you receive the highest honors of all.
Locating critical components Damaged components, burned printed circuit PC boards, and pulled PC wiring indicate that the TV chassis has sustained lightning damage.
Take a good look at the defective chassis. Visual inspection has repaired thousands of electronic chassis. Watch out for visual scars, such as a burned resistor, worn connections, arc-over parts, cracked boards, overheated components, and wear and tear.
For instance, firing or arcing inside the picture tube can indicate a cracked cathode-ray tube CRT gun assembly Fig. Arcing between parts on PC boards results from liquid spilled inside the chassis.
This unbalanced saturation causes a significant power reduction. The only way to recover power consists of the addition of expensive bootstrap capacitors. Referring to the circuit of Fig. This means that the output buffer is intrinsically stable and not prone to oscillation. Most remarkably, the above feature has been achieved in spite of the very low closed loop gain of the amplifier 20 dB.
In contrast, with the classical PNP-NPN stage, the solution adopted for reducing the gain at high frequencies makes use of external RC networks, namely the Boucherot cells. The output swing is limited only by the Vcesat of the output transistors, which are in the range of 0.
This particular function allows gain compression facility whenever the amplifier is overdriven, thus obtaining high quality sound at all listening levels. For this reason an input bias current compensation is implemented to reduce the voltage drop across the input resistors, which appears amplified at the outputs.
Gain Internally Fixed to 20dB in Single Ended, 26dB in Bridge Advantages of this design choice are in terms of: components and space saving output noise, supply voltage rejection and distortion optimization.
While in muting the device outputs becomes insensitive to any kinds of signal that may be present at the input terminals. In other words every transient coming from previous stages produces no unpleasantacoustic effect to the speakers.
Another situation under which the device is totally muted is whenever the supply voltage drops lower than 7V. This is helpful to pop suppression during the turn-off by battery switch.
Easy Single Ended to Bridge Transition.
The change from single ended to bridge configurations is made simply by means of a short circuit across the inputs, that is no need of further external components. In case of working in single ended conditions the polarity of the speakers driven by the inverting amplifier must be reversed respect to those driven by non inverting channels. Te chnician. A sst.
