Make sure all the chips are seated and positioned correctly - if they are ok, then check back here.

Are the 10.02 for a shaker motor LE ? Then you need a pal chip too.

LTG : )™

I know this may be obvious, but are you 100% sure that a chip leg isn't bent?

I may be wrong but, I remember that my first pal chip was bad and 10.02 ran fine without the pal.

Also you are doing both correct? the CPU and Display Roms? And you WILL need the LE Pal chip for version 10.02 to work.

Okay to add, OS8 is only needed if you are going to add the shaker motor option. If you are not sure of your version, count the blinks at LED 1 on boot up. If it's 4 then it's OS4, if it's 8 blinks then OS8.

You will however for sure need the LOTR LE Pal chip to run version 10.02 and you should be doing both CPU and Display.

Just for the hell of it, what is the OS ver?

try the old chips if you still have them, lets narrow down, boards, connectors, chips and OS

Ok now with the old chips installed reseat all the ribbon cables especially the one to the display driver board.

If your light on the IO driver board is flashing and not going solid at L204 you are in constant reset.

Check your chip at U210 next to the LED L204 on the IO driver board, just make sure you don't have it in backwards or a leg not seated in the socket.

Found this:

If L200 is lit on the CPU board, then the CPU board is running. The last LED to look at is L204 on the Power Driver board.

If this LED is not lit, it's either because the CPU is in reset (L200 isn't lit) or the voltage is below 4.75v. If L204 is pulsing on and off (CPU L200 lit), this means that the watchdog on the Power Driver board is not being fed from the CPU board. Thing to check there is the ribbon cable and connectors from the CPU CN1 to the Power Driver board J1.

Here is the complete post on this from Viperrwk and few months ago but I think yours is more of a CPU seating / connector issue as outlined above.

"In order for a WS board to boot, on the Power Driver board (the one below the CPU board) you need at least the L2 (5v) and L203 (12v) LEDs to be on. That's because the 12v feeds the regulator for the 5v so both are necessary to have the voltages present for the board to boot. If these are not lit solidly, the CPU will be held in reset and never start.

On the CPU board, at least L201 has to be lit solidly for the board to boot. If it is, it shows that the 5v has made it from the power driver board and is powering the logic on the CPU board.

Having LED2 lit simply means that the 5v that made it to the board has been regulated to 3.3v for the Xilinx for the sound and LED1 shows that the sound section is running.

If you have all those LEDs lit the next thing to look for are L200 on the CPU board and L204 on the Power Driver board.

L200 only lites when two conditions are met: the voltage is above 4.75v and the EPROM bank select signal is running. If L201 is lit but not L200, you have a problem somewhere on the CPU board - either ROM, RAM, CPU, sockets, battery damage, other board damage, etc. on the CPU board.

If L200 is lit on the CPU board, then the CPU board is running. The last LED to look at is L204 on the Power Driver board.

If this LED is not lit, it's either because the CPU is in reset (L200 isn't lit) or the voltage is below 4.75v. If L204 is pulsing on and off (CPU L200 lit), this means that the watchdog on the Power Driver board is not being fed from the CPU board. Thing to check there is the ribbon cable and connectors from the CPU CN1 to the Power Driver board J1."

U210 is the CPU ROM

Okay when you are looking at U210 ( CPU ROM ) the notch in the chip should be going towards the bottom of the board, not up towards the batteries

Did you touch the U213 chip at all, the Pal chip? That is just left of the CPU chip, also notch toward bottom of the board.

In addition the display controller board, the U5 chip should have the notch going toward the bottom of the board as well, if the board is upside down because you laid the display on the glass to to pull it, the U5 chip is then upside down and the notch should now be on top when reading all printed text upside down.

wait, you flashed the OS? Did you move the jumpers back?

yes but jumpers had to be moved to flash it, then you put back the boot flash chip and move the jumpers back again to their original spots and boot the game up

Ok one sec let me find the instructions

maybe it can be re flashed.

Atmel Flash Memory Installation Procedure (on CPU/Sound Board II only)
A Bootflash O/S 8 Sound EPROM (512K) (Checksum $8F2E) is required for this installation.

Step 1: Turn Pinball Game OFF (remove backglass for procedure). Reference the above CPU/Sound Board II Component Layout drawing for the locations of U7, JP2, JP3, JP4 and LED1.

Step 2: Remove the current Sound EPROM at U7 and replace with Bootflash O/S 8 Sound EPROM in its’ place.

Step 3: Move the jumpers at locations JP2, JP3 & JP4 to the opposite position.
Jumper JP2 covers RIGHT 2 pins move to LEFT 2 pins

Jumper JP3 covers BOTTOM 2 pins move to TOP 2 pins

Jumper JP4 covers TOP 2 pins move to BOTTOM 2 pins

Step 4: Turn Pinball Game ON. Wait for LED1 to start flashing continuously (this indicates flash procedure was successful). Note: This usually takes a few minutes.

Step 5: Turn Pinball Game OFF.

Step 6: Remove Bootflash O/S 8 EPROM at U7 and replace with original EPROM you had just previously removed.

Step 7: I M P O R T A N T ! ! >>> Move Jumpers JP2, JP3, JP4 back to their original positions.
(JP2 = RIGHT, JP3 = BOTTOM & JP4 = TOP)

Step 8: Turn Pinball Game ON. Watch LED1 upon power-up. The LED1 will flicker then flash 8 times.

The flash chip is at U7 not U12, if you didn't get a chip that is for an OS8 flash then the above don't apply.

put the original U12 chip back, get the flash chip and install it at U7, move the said jumpers go through the moves and see if it flashes the chip successfully with constant flashing at the end. Then put back the original U7 chip and MOVE THE JUMPERS BACK (lol) then power up and boot up the game and lets see.

you tried the flash as outlined above with the proper chips in their locations? waited to see constant flashing then shut down and move jumpers back and reinstall the original u7 chip again?

Buddy...you're everything that's right about Pinside. Keep up the good work! And I hope you're able to solve the issue, Maple!

If led 200 is solid, that's good, if led 204 is pulsing that's a watchdog issue as outlined here:

If L204 is pulsing on and off (CPU L200 lit), this means that the watchdog on the Power Driver board is not being fed from the CPU board. Thing to check there is the ribbon cable and connectors from the CPU CN1 to the Power Driver board J1

Try those connectors again now, take them fully off and reseat them.

Thanks, just trying to give back what I can when I can as others have done for me through the years.

Sounds like you see something

shit

do you have a rom burner?
