This is a Sony Triniton, Model KV-20M10, manufactured July 1995. There are no blinking lights (there really are no lights to blink) or clicking sounds. The described symptom on this particular model using a BA-2 chassis would indicate an internal hardware issue. The unit would have to be opened up for visual inspection, voltage measurements, confirm fault and effect repairs. Are you then considering

a DIY (do-it-yourself) repair approach Are you familiar with electronic components, have access to / comfortable in the use of a multimeter and perhaps even a soldering iron/hot-air station I would like to try the DYI approach since I have nothing to lose. Getting it professionally repaired would probably be close to the cost of a new TV, don`t you think. I have a small handheld meter which shows volts, ohms, and whether two points are connected. I also have a soldering iron, which I am more familiar with than the meter. Am I adequately supplied to delve into this venture First, get the back cover off (4 screws). Closely inspect the rear right side (looking from the back). The high voltage transformer (FBT) is located here with a big red/ (sometimes black) wire going to the rear top of the tube. Check the FBT for any sign of cracks or high voltage leaks, arcing. Carefully plug in and power on the TV. Check if there is a glow at the very rear of the TV. This is the heater voltage and it also is an indicator that the high voltage/horizontal is most likely operating. It is also possible to check the FBT for stray high voltage. With the cover still removed, power on the TV and darken the room. Within a safe distance, check for any bluish glow or high voltage arcing. I see no signs of cracks or arcing in the transformer. The only glow I see when plugged in and powered up, is in the large glass tube plugged into a small circuit...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
