WE INHERITED A MITSUBISHI 1080 DIAMOND, TV, 65 INCH. HD/DVR CABLE BOX NOT WORKING, NOT SURE WHAT INPUT TO USE ON THE MENU. PLUGGED CABLES INTO COMP 1 AND COMP 2, CHOOSE SAME ON THE TV MENU, COMES UP SCRAMBLED. HELP!
COMP 1 and 2 are for 480i/p sources. Hook it to the 1080i capable on the back. Also make sure the HD DVR is outputting 1080i not 720p. The Mits can not disply 720p and will show a scrambled screen if you try to.

Since this is an older first generation (1999) HD TV it may not be compatible with newer HDTV receivers because the standards back then were different - Make sure the HD cable box is plugged into the HD component inputs on the back of the TV (not the DVD inputs) and that the menu setting on the TV is set to DTV (not RGB) video. This TV will only accept 480i and 480p signals on the DVD input. Also the HDTV input will only accept 480i,480p and 1080i (it will not work with a 720p signal,make sure your cable box is not set to that mode)
if it is a ws-65613 you would have to be connected to the DTV component input on the back of the set as this is the only HD input for this model.
If the set will not go to that input (skips it by) let me know as there is a way to restore missing inputs--if you hook HD in any other way it will not work on this model; let me know if you need help;
This is a convergence rpoblem that is either bad connections on the pins of the convergence ICs or defective ICs. If you can solder and are comfortable working inside TVs where there are potentially dangerous high voltages, let me know and I'll provide additional details and instructions for fixing this yourself.
When I hooked up my HD cable box using an HDMI cable, I had to go into the cable screen menus and select HDMI output. You may have to do something similar when using an S-video cable. Your DVD recorder doesn't seem to have an HDMI input, so you'll have to use the S-video or (worst case) composite video (red, white, yellow cords). Your cable box may also be scrambling the signal so that you can't record. That may be why you can record by bypassing the cable box.
