I have a 4-year old KCMS145JSS-1 microwave with a broken display. Some segments work, but most do not. If I remember what time I entered all functions seem to work fine. Do I need a new control panel? Is there a diagram to assist dis/re-assembly? I have done quite a bit of repair work and minor electronics but never on a microwave. Any help you can offer will be appreciated!!

1. Defective controller or its power supply.
2. Broken display panel.
3. Oven needs to be reset (pull plug for a minute or two to reset). God bless you
see the diagram and pictorial and proceed with common sense: 1) test the fuse for open or band contact with VOM,see the diagram attached how to do it 2)check the switch door hook or door release button,when they are broken they do not touch the switch, and will NOT start. test for open see the diagram
I was not aware you could turn off the display, maybe it is just a bad display and you need to replace the board??!!
Ive been repairing Microwaves for 37 years. i do not remember seeing one where you could just turn off the display.
Not a complete answer, but may help describe problem: Our R-510B should be the same except for color, and for several years it has intermittently messed up its display. The left side two segments on the units digit won't light up. So a digit 8, without the two vertical bars on the left, comes out as a letter E reversed left to right. Any digit that uses the two left segments (traditionally labelled segments E and F when talking about 7-segment displays) comes out wrong. Every thing else works fine. I can't tell if this is your problem.
This is almost surely a bad contact at the interface between the LCD display panel and the PC board: Typically there is a "squishy" conductive strip that connects them, and I expect grease has gotten in there. If so careful disassembly and cleaning with a mild solvent should fix it. Since we can live with it, and it usually fixes itself in a few weeks, I have not got around to taking it apart.

have a good look at front to see reset??.press it once it comes back on unplug from the wall and & open it up and go to the part and give it a good clean with wd40, check the push pad for ware & tare dirt gathers and builds up

I'm assuming your correct model number is KCMS145JSS?
You have a broken "release lever", part number AP3033332.
It's reference number 7 on the exploded view diagram found here:

You can order it by part number from Appliance Parts Pros here: http://tinyurl.com/gv383
