Description

The book dealt with more than 200 different practical fault receivers separately - repair the power supply, the processor and the receiving part, path A / V. Recommendations for replacing chips, unique practical recommendations for repair without replacement in the partial failure of the processor or the input block.
The main rule book - just useful information, it will be easy to study the scheme and operation of the receiver units.
The author of more than 10 years doing repairs receivers, shares his experience in the book and hopes that it will be useful as a master radio, as well as all those who, though having little skill with a soldering iron, he wants to repair your tuner.
Also considered repair folk receivers:
- ORTON 4100s (STARTRACK 55X, etc.) Marriage processor ALI3329C (20-30 minutes after the signal disappears): the restoration of normal operation without replacing the CPU (a unique simple solution developed by the author himself and has no analogues);
- GLOBO7010 (et al. ALI3329V processor) with the marriage stick (when disconnected from the network settings are lost, instead of the program - "uuuuuuuyyyyy"). Variants of the solution.

Additional information

The book deals with the following problem:
Lit Fuse network. The power supply will not start. The output voltages BP underestimated or overestimated pulsate. BP buzzing, beeping, or hush. Immediately / or intermittently / lights IC PD. Check analogues and replacement of a power supply IC available. Do not operate the control panel buttons. It does not work control. Replacing RAM, FLASH, EEPROM. No signal. Understated quality of the signal, the image fray. Periodically, the signal disappears. Do not operate the channels V or H polarization, the upper or lower Ku-band, high-speed or low-speed flows. Tuner hangs on display 0, 5, 6 or 8. The tuner does not start or some time after switching on. The tuner does not start, the display is off. The tuner does not start, the display 0000, 8888, - - - -, ON, ASH, the channel number blinks ON, flash ON and the red LED lights up red or green LED, flashing both LEDs. The tuner does not start, clicks BP. No pictures and / or / sound. Signal levels are, and there is no picture and sound. Poor picture quality: dull, blurry, understated contrast, negative, double, strip, mesh, color interference. No synchronization. No color. Instead, the color image is periodically cast aside red or green. No RF signal at the output. Strong distortion, crackle, rustling, background, hum, noise, rattling. Tuner periodically reloaded. Spontaneously change channels. Not saved settings. No new channels are stored. When disconnected from the network resets the receiver and / or / channel list. The tuner is not written or not written until the end. Digits flash on the display. The receiver can not read the card. Poor working motor control. Different fault remote control and many other faults receivers.
