Description refers to the VX-G142 television receiver with a built-in video recorder (OVD-5 tip mechanism).
All settings related to the service mode are made using a standard remote control transmitter toring.
Set parameters are signaled on the screen in the form of OSD messages.
Before entering the service mode, the tester must be connected to the antenna input of the receiver.
Pre-programming of non-volatile memory If you need to replace the non-volatile memory, use the pre-programmed memory. The necessary ^ coordinates, initial entries in specific memory cells can be made as follows:
• set the volume to the minimum,
• press and hold the [VOLUME DOWN] button on the local keyboard and then send the
kaz [6] from the remote control transmitter,
• the following message appears on the screen of the receiver:
where: item 01 specifies the cell address,

1. KEEP THE NOTICES
As for the places which need special attentions, they are indicated with the labels or seals on the cabinet, chassis
and parts. Make sure to keep the indications and notices in the operation manual.
2. AVOID AN ELECTRIC SHOCK Aiwa VX-T1470PH TV Service Menu
There is a high voltage part inside. Avoid an electric shock while the electric current is flowing.
3. USE THE DESIGNATED PARTS
The parts in this equipment have the specific characters of incombustibility and withstand voltage for
safety. Therefore, the part which is replaced should be used the part which has the same character.
Especially as to the important parts for safety which is indicated in the circuit diagram or the table of parts as
a mark, the designated parts must be used.
4. PUT PARTS AND WIRES IN THE ORIGINAL POSITION AFTER ASSEMBLING OR WIRING
There are parts which use the insulation material such as a tube or tape for safety, or which are assembled in
the condition that these do not contact with the printed board. The inside wiring is designed not to get closer to
the pyrogenic parts and high voltage parts. Therefore, put these parts in the original positions.
5. TAKE CARE TO DEAL WITH THE CATHODE-RAY TUBE
In the condition that an explosion-proof cathode-ray tube is set in this equipment, safety is secured against
implosion. However, when removing it or serving from backward, it is dangerous to give a shock. Take
enough care to deal with it.
6. AVOID AN X-RAY
Safety is secured against an X-ray by considering about the cathode-ray tube and the high voltage
peripheral circuit, etc.
Therefore, when repairing the high voltage peripheral circuit, use the designated parts and make sure not
modify the circuit.
Repairing except indicates causes rising of high voltage, and it emits an X-ray from the cathode-ray tube.
7. PERFORM A SAFETY CHECK AFTER SERVICING
Confirm that the screws, parts and wiring which were removed in order to service are put in the original
positions, or whether there are the portions which are deteriorated around the serviced places serviced or not.
Check the insulation between the antenna terminal or external metal and the AC cord plug blades. And be sure
the safety of that.
(INSULATION CHECK PROCEDURE)
1. Unplug the plug from the AC outlet.
2. Remove the antenna terminal on TV and turn on the TV.
3. Insulation resistance between the cord plug terminals and the eternal exposure metal [Note 2] should be
more than 1M ohm by using the 500V insulation resis-tance meter [Note 1].
4. If the insulation resistance is less than 1M ohm, the inspection repair should be required.
[Note 1]
If you have not the 500V insulation resistance meter, use a Tester.
[Note 2]
