A TV Repairman Easier
A service provider could be at your front door ready to help with your repair needs on the day and time that’s most convenient for you. Yes, you can repair a broken LCD TV screen, but most people find it’s cheaper just to buy a new set. TV and electronic repair workers may be self-employed or work for a repair firm or a retail store.
Typically, a tap from the flyback transformer feeds a diode and a filter capacitor to produce a sample DC voltage proportional to the high voltage. Typically, a reference circuit on the output side senses the primary output voltage and turns on the LED of the opto-isolator when the output voltage exceeds the desired value. AC voltage enters to the primary side of linear transformer and then converted the AC into a lower or higher AC voltage depending on the secondary winding. A failure of the horizontal output transistor or power supply switchmode transistor will blow a fuse or fusable resistor.
Not all LCD TV models have good response times for fast moving scenes, but you will find quality models with pretty good response times. Because motion is fleeting, though, many viewers don’t really notice the blur all that much, especially with typical TV programs. One problem that some people have with LCD technology is that it is limited when compared to other types of HDTVs.
