TV not turning on the light source lamp is a common situation for many people. What is the cause and how to solve it? Well, let's explore the full review through the following article. TV is one of the most important electronic items at home.
In fact, as a means of entertainment, people are willing to choose several expensive TV brands to guarantee quality.
However, it does not rule out the possibility of the television we have experiencing damage over the years of use.
TV does not turn on but the light source is one of the problems we often encounter, you know.
This can happen due to many factors or causes.
1. Loose Power Cord
A loose power cord is one of the causes of the TV not turning on but the power light is on.
This cause can also arise when the television is moved to another area so that the cable connected behind it becomes loose or detached.
2. Problematic Elco Components
A problematic elco component can be the cause of the TV not turning on but the power light is on. This condition is called standby shutdown which causes the TV not to turn on but the power light remains on.
3. Horizontal return not working
The horizontal circuit is not functioning normally which is the cause of the TV not turning on even though the power light is still on.
Normally the short transverse transistor does not receive an input signal from the driver so this component does not work.
While the cause of the horizontal driver not working is that there is no voltage applied to the driver because the driver transistor is dead. 4. Voltage drop settings
In general, the voltage drop from the regulator can cause problems with the TV.
Apart from the TV not showing up, another reason is that the TV does not show up.
This may be due to interference from the TV tuner.
This is because the voltage drop regulator causes the TV to fail to turn on and usually only occurs at some high voltage levels. How to fix a TV that won't turn on but the power light is on
Basically, fixing a dead TV even though the power light is still on can be done in many ways. Anything?
1. Disconnect all cables and open the TV chassis
Why doesn't the TV turn on?
The first thing you can do is open the TV frame.
However, first make sure all the cables are not connected to the current. Next, measure the voltage on the B+115 section of the TV.
Generally, there will be 2 conditions you will find.
First, if the measurement shows B+ is normal, check the transistor components.
Second, if B+ is not normal, i.e. it is going down, disconnect or remove the horizontal transistor and measure again to see if it is still going down.
If it does not go down, the main problem is in the transistor.
