What other components should you pay attention to? Let's look at the main situations:

The diode bridge fails. The component rectifies the current. If the circuit experiences voltage drops, one of the diodes may burn out. It even happens that two diodes fail at once, so the breakdown should be determined using a “ring test”.
The resistor fails. The purpose of this part is to remove potential from the cathode-ray tube.If the component stops doing its job, a “rainbow” will appear on the TV screen. In this case, the thermistor or inductive loop may burn out. In this case, simply turn off the power and use a tester to determine the problem.
Do-it-yourself repair of CRT TVs is the most common replacement of burnt-out components, but what about modern models?

We do repairs correctly
General instructions should not be forgotten. It is advisable to dismantle usa telegram data the main board to avoid the risk of electric shock. First, the EL tube electrode will need to be discharged.

Important! During restoration work, try not to touch metal parts.

Use a screwdriver to pry up the rubber band.
Swing the component and remove the EL tube electrode.
Touch the rod to the body of the device, thereby discharging the part.If you can find ground, it is better to use it. The most ideal option is a European-type socket with the terminals connected correctly.
When discharging, you should hear characteristic clicks. Discharge the component until you no longer hear them.
Each TV has a main board, which is responsible for “controlling” the equipment. Remove this part and inspect the radio components on the board.
If necessary, replace swollen capacitors, resistors and burnt-out elements.
Important! If you still haven't managed to repair your TV yourself, it's probably time to replace it with a new, improved model. In our separate review, you'll find out which TV brands are better.
