NTSC (480i) signal generator. Hitachi recognizes that few companies offer HDTV or SDTV signal generators and that the cost of these generators is sometimes prohibitive. For this reason, we suggest the use of a set-top-box for HDTV and SDTV adjustments. Usually, there is a switch on the set-top-box which enables it to output HDTV (1080i or 720P) or SDTV (480P) signals even with no input.

Page 156 DP33KA/B STEP INSTRUCTIONS IMAGE Do the same thing on the right side of the TV. Disconnect the wiring to the right Deco Panel as shown. Now move to the chassis area on the back of the TV. Remove 15 screws that hold the lower rear board. Remove 16 screws that hold the back cover assembly and screen assembly to the cabinet as shown.
Page 157 DP33KA/B STEP INSTRUCTIONS IMAGE Remove 3 screws which hold the lower left corner of the screen assembly. Remove 2 screws which hold the lower right corner of the screen assembly. Before removing the screen assembly completely out, remove all of the wires (with 4 connectors) connecting to the Magic Focus sensor board first.
Page 158 DP33KA/B STEP INSTRUCTIONS IMAGE Continue at the front, remove 4 screws that hold the left side of the back cover assembly. Remove 3 screws and a piece of metal (slide outward) that holds the right side of the back cover assembly. Lift the back cover assembly straight up from the cabinet.
Page 159 Use additional help if necessary. The Light Box is now ready for easy transport to a designated service and repair facility. NOTE: The only difference between the Disassembly Instructions for the 46F510 and 46F500A are the speaker grill and control panel.
