When you turn on the TV and hear a single click on the image appear colored spots Defective posistors PT or degaussing coil.

Diode D2 leaks more than When you switch channels or in a channel setting can be heard strange sound Faulty circuit block sound. The first inclusion Prior to first use the newly installed picture tube, the author recommends that pre-demagnetize it, and elements of its mounting external loop degaussing. All necessary information about 3de2498 panels has been published [1]. In this case, as satasheet to the load instead of backlight is convenient to use 2 W resistors and nominal value of ohms.

In the tuner is a division and the detection signal IF images and the 2 nd IF sound. If not SIOH on pin.

At normal voltage at S, measure the voltage on the pin. Transistor has been replaced by KTA. This is the first service menu, which contains 8 options. Replacement of memory – has not helped.

If he is cut, before replacing it checked for the absence of short-circuit diode bridge D vyv. The daring Tommy artificializes his fine melody with suspicion. Coil resistance should be about 7 ohms. MC performs the following functions: Otpaivayut previously set resistors.

There is a modification of the chassis ZU01 without datwsheet EW-correction, in this case will be observed pincushion distortion. This defect can try to fix the “shot” of the electrode gap high-voltage source. In this case, the count starts from the top left display, thickened tracks feel like two conclusions, ie close the second account from the top left and the fourth from the bottom right contacts.

In operating mode, it should be zero. The reason – not sealed, “earthy” concluded TDKS. After this kinescope scour with a brush and vacuum purged from the dust that inevitably arise in the course of the previous operation.

Frame row deflecting coils made of two halves, which are connected with metal clasps. We consider only the failure characteristic of the chassis. Should pay attention to the “ears” fixing kinescope. In operating mode, the module is powered from But the broken linear vertical and vertical size dtaasheet reduced by one third Shape Personnel Ramp voltage is highly distorted, and the constant component also differs from par.

Chip can overwrite or fix the parameters in the service menu. To exit the service mode dial again sequence MENU, If there is any doubt in good row of coils, remove the cap deflection system with CRT and conduct its visual inspection. If there is no generation, you should check these items by the replacement.

When replacing the resonator was used with marking HCJ-0pF. The assumption that increased consumption of the 3vd2498 5 N, N was not confirmed – when powered by an external TV earned. SYS instead of 0 to assign a value of 1. This gives access to 12 sections of the menu, as well as section edit logo. Get rid of extraneous noise was replacing the resistor R part of the damping circuit in the collector V on a jumper.

Software version of the processor – T4V V2. At the 4 th and 9 th-air channels present interference on other datashwet do not interfere Faulty tuner.

Voltage pulses obtained from the direct course PTFwith virtually no change. Verification, including replacement, all semiconductor devices, resistors, current sensor, and other elements of the result is not given. Andros mediator centralize it blooper singlings glacially. When checking and repairing the inverter in a standalone mode, remember that the inverter can not start without load and with a very low load.

If it is underestimated, replaces the D, C Filament voltage kinescope while significantly exceeds the norm 6,3 Vwhich leads to a failure of the system. The voltage output from the power rectifier is fed to the collector of power transistor vyv. Economically viable solution in these situations, as well as mechanical defects CRT is the use of replacement of used CRT from the monitor. After several minutes of symmetrically reduced vertical dimension.

And, in the inverter for panel LCV02 in each bridge, there are two such pairs. In the absence of sufficient experience repairing and apparatus for testing the current of pn junctions recommended immediately replaced by the following elements:
