Circuits of the Basic TV Set and What They Do - Part 2

In Circuits Of The Basic TV and What They Do - Part 1 we discussed the standby power supply, main power supply, and the horizontal and vertical deflection circuits. In Part 2 of this series we'll dig a bit deeper inside a typical TV set, and cover degaussing circuits, tuner circuits, and common tuner problems.

Can I Use My TV Speakers Instead?


I would like to get my home theater system (Samsung HT-Q45) hooked up so I can watch DVDs with the TV speakers at times... without using the surround sound speakers themselves. There will be other times I would like to use the surround, just not always. I would also like to be able to use the same components. Is this possible?

Understanding Sony Television Blinking Codes

Many of the later model Sony TV’s have a built in self-diagnosis function. If the timer/standby indicator is blinking, this could be an indication of a problem with the unit. The diagnostic blinking will occur automatically with no action required by you to engage it.

The timing of the blinking you see would be as follows: two to nine blinks, (depending on the fault), about a third of a second apart, then a pause for 3 seconds, then the two to nine blinks about a third of a second apart again.

Troubleshooting a TV For a Dead Condition

When it comes to TV sets, the first thing to always remember is that if you have no electronic experience or training, there really are no user serviceable parts inside of the TV, as they're all solid state. You're going to need to know how to use a simple digital or analog multimeter, and you should also know how to solder and unsolder, as almost all parts in most TV sets are soldered in place on the printed circuit board.
