I have only used the course and make the room as dark as I can or throw a quilt over the set and me. Leonard in the case where "there is a gray scale tracking problem" did the jig dramatically improve the tracking, or to the point that you were satisfied with the result?

If you need the jig I can send you the .pdf. From Sony: 3-1. SCREEN VOLTAGE ADJUSTMENT (COARSE ADJUSTMENT) 1. Receive the Monoscope signal. 2. Set 50% BRIGHTNESS and minimum PICTURE. 3. Turn the red VR on the FOCUS block all the way to the left and then gradually turn it to the right until the point where you can see the retrace line. 4. Next gradually turn it to the left to the position where the retrace line disappears. 3-2. SCREEN (G2) ADJUSTMENT (FINE ADJUSTMENT) Fine Mode is recommended to set screen controls to their optimal condition. It is necessary to build the simple jig, illustrated below, using 3-watt resistors. Please note, that if the proper voltage is not obtained with their listed values, resistors, then please increase or decrease one of the values in the resistor network to obtain the correct voltage. 1. Select VIDEO1 mode without signals. 2. Connect G2 JIG. 3. SW on JIG. 4. Connect an oscilloscope to the TP701(KR), TP732(KG) and TP761(KB) of CR board, CG board and CB board. 5. Adjust R, G and B screen voltage to 170-173V with screen VR on the Focus block. Leonard G.
