When you turn the power indicator turns on for 1 second and switched off, TV does not work Composition of the chassis: For large diagonal screens, an additional scheme to collect EW-correction, or install dwtasheet missing components on the chassis, if provided such an option.
If after replacing the faulty elements problem remains – the cause of CRT.
The output of error amplifier vyv. Breakage of the capacitor S As a rule, in instances of strong heating V its face value is low If the defect does not disappear, check elements R 0,47 OmL, the datzsheet part of the diode assembly D between pin.
3DD2498 – NPN
Often the cause of this fault is the breakdown of a key transistor V SB in the secondary circuit unit. Next to exit the menu, click on the panel VOL-and P. If the voltage is lowered by pin. Coil resistance should be about 7 ohms. The menu has three submenus.
If it is close to zero, and there is no voltage, check the IP. If the voltage on the findings will not change and remains equal to 3. Cause of the problem – the microcontroller ICS.
The screen will display TEST red. Chip can be potted especially in the last modifications of the remote control, for example, in the remote type 52N8.

If after that TV is on, gradually increasing the voltage on datashret accelerating electrode before the ruling. The author met the following defects TDKS: Transistor has been replaced by KTA. Through the steps outlined above provide the desired size of the raster. If in the short-circuit pin. The reason – the breakdown of the microcontroller input static electricity.

To facilitate the search for material applicability of microcontrollers MM8-xxx and graphics processors in Mh various TV summarized in Table. Further adjustments with image parameters is carried out in service mode.
Unable to tune in to television channels, after setting the TV does not respond to control button If when you set up in automatic mode, the image appears briefly, but the channel is not stored, check the voltage on the pin. Change denominations Cox and Cs to obtain the desired size in the horizontal with an acceptable linearity was not possible.
TV does not turn triggered protection UPS power supply unit goes into operation at short circuit in the load When testing without watering Wed output transistor Q is determined as faulty. When repairing the inverter is important to know some of the characteristic voltage on pins U1-type OZ If these items are OK, replace the MC. Volvulus screen vertically in the upper part In the position S mistakenly installed capacitor pF instead of 10 pF.

Increased the size of the horizontal Not soldered to the board one of the pairs findings optocoupler PCS. Motochnye data in the process of adjustment had to pick up. Synchronizing internal oscillator provides a constant voltage generated by pin.
There is a modification of the chassis ZU01 without chains EW-correction, in this case will be observed pincushion distortion. When you turn on the TV there are three colored lines above the frame, and AV-mode same 3ddd2498 visible line flyback Check for damaged capacitor C On any of the test images show some noise, reminiscent of dayasheet high-voltage, which visually looks like a random white dots – strokes, streaks in the image.
Schematic diagrams of each of these inverters are divided into two units:
