GMA 7 LIVE STREAMING
GMA Network (GMA) is a major commercial television & radio network in the Philippines. GMA Network is owned by GMA Network, Inc. a publicly listed company. Its first broadcast on television was on October 29, 1961, GMA Network (formerly known as DZBB TV Channel 7,RBS TV Channel 7, GMA Radio-Television Arts then GMA Rainbow Satellite Network) is commonly signified to as the "Kapuso Network" in reference to the outline of the company’s logo. It has also been called the “Christian Network” which refers to the apparent programming during the tenure of the new management, which took over in 1974. It is headquartered in theGMA Network Center in Quezon City and its transmitter is located at Tandang Sora Avenue, Barangay Culiat also in Quezon City.Read more about GMA 7. or visit GMA network official website.

ABS-CBN 2 Live Streaming
ABS–CBN Corporation (PSE: ABS and ABSP) is a Philippine-based media conglomerate. It is the Philippines' largest media and entertainment conglomerate.The corporation was the merger of Alto Broadcasting System (ABS) which at that time owned by James Lindenbergand Antonio Quirino, and the Chronicle Broadcasting Network (CBN) owned by the Lopez's. Founded on June 13, 1946 by James Lindenberg as Bolinao Electronics Corporation (BEC), it was incorporated as ABS-CBN Broadcasting Corporation in February 1, 1967. On August 18, 2010 the corporate name was changed to ABS–CBN Corporation, after dropping the name "Broadcasting." The common shares of ABS-CBN (PSE: ABS) were first offered in July 1992. The PDRs (Philippine Depository Receipt) (PSE: ABSP) were offered in October 1999.Read more about ABS-CBN from wikipedia or visit their official website.

SAFETY PRECAUTIONS
IMPORTANT SAFETY NOTICE
Many electrical and mechanical parts in every unit have special safety-related characteristics. These parts are identified by yellow triangle in the Schematic Diagram and Replacement Parts List.
It is essential that these special safety parts should be replaced with the same components as recommended in this manual to prevent X-RADIATION, Shock, Fire, or other Hazards.
Do not modify the original design without permission of manufacturer.
General Guidance
An lsolation Transformer should always be used during
the servicing of a receiver whose chassis is not isolated from
the AC power line. Use a transformer of adequate power rating
as this protects the technician from accidents resulting in
personal injury from electrical shocks.
It will also protect the receiver and it's components from being
damaged by accidental shorts of the circuitry that may be
inadvertently introduced during the service operation.
If any fuse (or Fusible Resistor) in this monitor is blown, replace
it with the same specified type.
When replacing a high wattage resistor (Oxide Metal Film
Resistor, over 1W), keep the resistor 10mm away from PCB.
Keep wires away from high voltage or high temperature parts
Leakage Current Cold Check(Antenna Cold Check)
With the instrument AC plug removed from AC source,
connect an electrical jumper across the two AC plug prongs.
Place the AC switch in the on positioin, connect one lead of
ohm-meter to the AC plug prongs tied together and touch other
ohm-meter lead in turn to each exposed metallic parts such as
antenna terminals, phone jacks, etc.
If the exposed metallic part has a return path to the chassis, the
measured resistance should be between 1MΩ and 5.2MΩ.
When the exposed metal has no return path to the chassis the
reading must be infinite.
An other abnormality exists that must be corrected before thereceiver is returned to the customer.

Leakage Current Hot Check
Plug the AC cord directly into the AC outlet.
Do not use a line Isolation Transformer during this check.
Connect 1.5K/10watt resistor in parallel with a 0.15uF capacitor
between a known good earth ground (Water Pipe, Conduit, etc.)
and the exposed metallic parts.
Measure the AC voltage across the resistor using AC
voltmeter with 1000 ohms/volt or more sensitivity.
Reverse plug the AC cord into the AC outlet and repeat AC
voltage measurements for each exposed metallic part. Any
voltage measured must not exceed 0.75 volt RMS which is
corresponds to 0.5mA.
In case any measurement is out of the limits specified, there is
possibility of shock hazard and the set must be checked and repaired before it is returned to the customer
