BEFORE RETURNING THE RECEIVER
Before returning the receiver to the user, perform the following safety checks.
1. Inspect all lead dress to make certain that leads are not pinched or that hardware is not lodged between the chassis and other metal parts in the receiver.
2. Inspect all protective devices such as non-metallic control knobs, insulating fishpapers, cabinet backs, adjustment and compartment covers or shields, isolation resistor-capacity networks, mechinira! insulators etc.

Precautions:
How to prevent
tricity
1. When replacing or handling the IC, be sure to put on your wrist a metal ring (earth
-
to ground.
*
Avoid touching the IC directly by hand as much as
--_
possible.
2. For the soldering iron and other jigs in use, be sure to connect them to ground so that their potential is the same as that of the PWB and/or IC.
3. The PWB cannot be connected to ground in some con­dition although you attempt to attach the rC to that PWB. In this case, be sure to keep the PWB at the same potential as ground by touching it by your hand on which a metal nng is put.
4. When handling the wear such clothes as not causing static electricity; the ones of wool, silk or synthetic fiber should be avoid­ed. This is Important in particular when handling the IC In a dry environment.

1 kHz signal does not appear, set the input sig­nal level at 52 dB again and follow the procedure in step 4 again.
Sub-brightness adjustment: R421
1. Turn S501 on by tipping it rightwards in order to let the raster be linear.
2. Set each control as follows:

13. Adjust brightness control and contrast control to obtain a dark picture. If the white balance is dis­turbed, adjust the bias control to obtain good white balance.
14. Again brighten the picture and adjust each drive control for good white balance as in step 12 above.

2. Set each control as follows:
l Contrast control: at MAX position l Brightness control: at CENTER position l Colour control: at CENTER position l Picture-tone control: at CENTER position
3. Connect oscilloscope to TP850.
4. Adjust R817 so that the white output (75%) and red output will have the same level.
Background adjustment: Screen control R862 R863 R864
R857-A/B
6. Remove oscilloscope from TP850.
7. Adjust the screen control so that raster of red, green, or blue appears dimly on screen.
