Wizard of Oz
Jersey Jack, 2013I just picked up a WozEC and it worked fine when I bought it. I brought it home and now it flashes No Signal Input. I called JJP support and they said I should try and jump the CPU board. I have attempted to jump start the CPU using the paperclip method described on JPP's support video, however the game is still not booting up. I checked the connectors, and nothing seems loose anywhere. Any idea where I should look next?? Thanks

Is the computer starting at all?
i.e. fan turning lights on the pc boards?
If not, it could be a loose power connector on the computer.
Either the 24 pin or the 4 pin near the cpu chip.
Or a blown fuse.
Quoted from Floyd:The fan does not run on start up. Only when I jump the main power pins (Green and Black) does the fan turn on. Also, when I just the pins the back box lights up.
Apologies if this is redundant information to you.
#wizard-of-oz uses a computer. The message “no signal input” means your monitor isn’t getting a video signal. This is usually because the computer hasn’t started. When you MOMENTARILY short the power pins you are stimulating pressing the start button on your PC. You should not be shorting the pins constantly just as you don’t hold down the power button on your PC. It will turn off after about four seconds if you do.
You said the fan starts up when you short some pins. Is the computer not booting at that point? If not, what is happening after the fan starts?
On the video from JJP support, they say to leave the paperclip inserted until code starts to appear on the screen, then remove the paperclip. When I perform the evolution, I can't get the code to boot. I tried like you said to just momentarily short the green and black wires on the 24 pin and the fans stopped and nothing happened.

The pins they are shorting are the reset. The pc won't boot if a jumper is left on the reset pins.
The pc however will boot if the power switch pins are jumpered only momentarity and the jumper removed as soon as the fan starts.
The same power switch pins that start the pc also shut it down if the jumper is left on.
Short press of the switch = on
Long press of the switch = off.
So, there are 2 sets of pins we can deal with.
Reset pins
Power switch pins.
Both are 2 pins in the little area labeled fp or front panel.
If you look carefully on the edge of the pc main board they are labeled
Power and reset.
On a failed boot JJP has recommended doing a reset.
Powering the game on with reset pins jumpered.
Power off the game, remove jumper and power the game back on to see if it boots.
On a failed boot (CPU fan not running), several things are in play.
Loose ram
Loose power connector near cpu (4 pin) loose 24 pin (atx) connector.
No power getting to mainboard.
Bad switch that stays pressed down or is incorrectly plugged onto reset instead of power etc.
It seems you are getting power so maybe loose ram or loose or incorrectly installed power switch connector.
I’m getting the same exact thing but all the fans (cpu fan) are running - the 27” screen just says “no signal” then goes off and the screen is black with nothing.
I sent an email to support on it but any help would be appreciated

Do you get the splash JJP screen when you turn the game on ? If not, the motherboard isn't starting. Power supply issue ?
LTG : )
When I turn it on, the “no signal” appears on the screen - all fans are running (3) but it does not boot up as usual. Screen just stays black. I did however changed out the 2032 cpu coin battery thinking that it might be dead (based on JJP vid) but still no iOS boot up. I tried the paper chip method but still nothing.

Sent you a pm or 2 lol

No signal means motherboard isn't doing anything.

Yup. LTG is on this! When was the last time the battery was changed?
Changed out the 2032 coin style battery as well. Still nothing.
Jp.

so, what was the fix?
Quoted from LTG:JJP sent a new motherboard.

was you the guy that diagnosed it lloyd?
Quoted from ccbiggsoo7:was you the guy that diagnosed it lloyd?
No. I believe he was working with Barry.
