How to Use a Satellite Finder to Receive Digital TV Signals

-


Satellite Finder is a handheld device designed to help technicians locate television satellites in order to position satellite dishes. It’s a handy device if you work with satellites often, but most people don’t have any real use for that functionality. 
They are simple to operate and are designed to be used while you're at the satellite dish so you don't have to check your signal strength at your television set. There are both analog and digital models available, both with and without internal power supplies.

The digital satellite finder is microprocessor controlled, making it very reliable and accurate. Signal strength is presented graphically on the LCD display in form of thermometer-scale and in numbers (0-99). It can also present pitch tones (the higher tone the better signal) on a buzzer. The digital sat-finder is very sensitive and can detect the weakest of signals, strong incoming signals (powerful satellite, big dishes) can easily be attenuated for better readout.

Features:
Mini size and light weight, really portable.
Designed with a compass for easier and quicker tuning.
LCD graphic display with LED backlit to show the satellite signal intensity.
Connect to your LNB and receiver to the satellite finder to track the clearest setting for the satellite you wish to tune to.
No external power or Batteries required, power supplied from your satellite receiver.
With buzzer and attenuation control function, easy user-friendly operation.

Step 1

Connect one end of the coaxial cable to the barrel connector on the satellite dish's low noise block downconverter (LNB) and the other end to the satellite finder meter. The LNB is the arm that faces the reflector dish.


Step 2

Loosen the nuts that allow the dish to be adjusted both along the horizontal (azimuth) and vertical (elevation) planes.


Step 3


Move the dish from side to side along the horizontal plane until you determine the position at which the satellite finder meter displays maximum signal strength.

If you're using an analog meter, you will find this position in increments. First, adjust the gain knob so the meter's needle reads half strength. As you move the dish closer to its optimal position, the meter may exceed maximum. If this happens, readjust the gain lower and continue to move the dish until you determine the position where maximum signal strength is received.

Step 4

Raise and lower the dish along the vertical plane until you determine the elevation at which the satellite finder meter displays maximum signal strength. If using an analog meter, you may have to adjust the gain as in the previous step.

Step 5

Tighten the nuts to lock your satellite dish into place.

Step 6

Disconnect the coaxial cable from the LNB on the satellite dish.

LCD/LED TV FLASH BIOS / EPROM programming with Serial Flash Memory - W25Q32FV

Image
The Winbond 25Q32 is a really cool part : high capacity (32 MBytes), very fast, good support for many standard instructions, supports wide bus modes... But it can be expensive depending on the application. Winbond 25Q32 is commonly used flash memory in the LED/LCD Tv's. Electricians in Sri Lanka call this with the different names such as  FLASH IC PROGRAMMABLE IC BIOS IC EEPROM IC EMMC IC SPI IC There are different series of IC's available in the market i'll mention few here 24 Series  25 Series  29 Series  Electricians mostly call this 24 Series only as Flash IC and the 25 series IC's called as EPROM/ SPI IC.  25 series is the one commonly used for LED or LCD TV's. SPI stands "Serial peripheral Interface" Serial peripheral means electronic device which can operate out of the microcontroller and which supports microcontroller functions. Also this is called as EPROM means "Erasable Programmable Read Only Memory". you can programme this with a bina

Double Image fault solution through CKV, CKVB and STVP Signal Cutting. What is Ckv CKVB STVP in LCD TV?  Pulse-pulse CKV, CKVB, STVP used as pulse “Row driver” or also called “Gate – driver”. … What is CKV in LED TV?  The CKV signal detection circuit comprises a first LED, a second LED, a first light sensor, a second light sensor and a judging module. A node between the first LED and the second LED is used for receiving CKV signals output by the control panel. What is pair a signal ? Pair signals mean after the level shifter section we will get the separate output like CKV 1 , CKVB 1 and STV 1. before entering to Gate Driver IC [ COF ] these three signals are synchronizing each other its called signal paring. depending on COF ic this pair will be increase or decrease. example single COF IC is available in scalar board single pair signal only available (ckv 1,ckvb 1, stv 1) ckv is a positive pulse and ckvb is a generally negative pulse.

CIRCUIT TO CREATE 16 DIGITAL INPUTS FROM 5 DIGITAL PINS OF ARDUINO MEGA

-
Image
If the circuit is not working, remove the potential divider resistors connected to the 9 th  pin of both 74165 ICs and connect the 9 th  pin of both 74165 ICs to corresponding digital pin of arduino mega directly without any resistors. That is, connect 9 th  pin of 1 st  74165 to digital pin 12 of arduino mega and 9 th  pin of 2 nd  74165 to digital pin 10 of arduino mega. From the circuit, it is clear that A – H pins of both 74165s is connected to 5V through pull up resistors of 1K. Pull up resistors helps to keep the state of A – H pins of 74165s to HIGH when the press button switches are not pressed. Similarly, when the press button switches are pressed, corresponding pins of 74165 get grounded through the press button switches. That is, state of that pins will become LOW.  Pin out Diagram of 74165 Pin out diagram of 74165 is given below. 74165 has 16 pins out of which eight pins (A, B, C, D, E, F, G and H) are parallel data input pins.
