Hello,

I just picked up a Pink Panther and put it together. Everything thing seems to be working correctly (game start up, ball ejects, flippers and scoring appear ot work okay, all lights work) except I have no displays - all dead - player, ball count, number of games.

I am quite new to SS games and not certain how to proceed. Any suggestions would be greatly appreciated.

Thanks in advance!

The first step would be to check that all the displays have dark spots in the corners, rather than white spots. Displays with white spots are bad.

Next, I usually clean the edge connector contacts with a pink rubber eraser to remove all the grime and tarnish. Those contacts should be shiny, not dull. Clean contacts allow better electrical connection between the pin and the contact.

The next step is to check that the necessary voltages are reaching the displays.

Hello,

I put in a new power board the problem continues - no displays.

I checked the power cable that goes in to the power board, and the voltages doe not seem correct.

As I am new to this, where would one check? According to the power board, there should be 2 x 60V incoming power, and the actual power coming in is much lower (less than 10).

Any advice would be greatly appreciated.

Thanks,

Hello

First disconnect all displays except the 4 digit display.

Power up and if display didn't come up, control if :
+42v DC is present on pin 17 on the 4 digits display connector
3v AC is present beteween pin 15 and pin 16 on the 4 digits display connector

If not present, there is some probleme on fuse or on power supply.

If display come up reconnect one by one each 6 digit display (power off each time before reconnecting)

May be one of the displays is faulty .

I installed a new power board, rottendog, http://rottendog.us/GPS081.html. There is no power at all coming out of the 40V pin & 60V pin that plug A2-J3 connects to. In order to get power to the displays, there should be power coming out of these pins.

suggestions?

Ok, and between pins 7 & 8 of A2J1, have you 60vAC ?

If not, check on pins 8 & 9 of the small transfo, it will be 60vAC

If not the tranfo is dead
If yes there is a problem with fuse F7 or fuse holder, or connectors.

If yes ... Your power supply is faulty, please consider unplug any displays, and re-check.
