picked up a very nice stern Galaxy and my displays were a little flaky so I did all the usual. repinned connector to the board. repinned connector to displays, replaced pins on display and resoldered pins from glass to display board.

here is what happens.

Displays work in #1 and #2 when 3 and 4 are out.
when I add displays #3 and #4 (with working displays) the displays in #1 and #2 get flaky like they are gassing, digets don't work 100% I am lost on this one. what would cause them to do that by adding display 3 and 4?

any help is much appreciated.

thank you in advance

At test point 2 on all 4 displays I get 146-152 Volts.

First picture is all 4 displays plugged w credit/ball

Second picture is with displays 3 and 4 disconnected

Third pic is with only player 1 and credit/ball display plugged in

also repinned connectors

I measured TP4 at 249 volts and TP2 143 - 146. looks like I am down on TP2. I repined the board and changed out 1 cap. on the board.
What would cause the lower voltage at TP2?

I can get the display up to about 168 volts by disconnecting the other displays. The more displays I disconnect the higher the reading on Player one display goes.

Sounds like you are on to something. Cant thank you enough!

looks like I have a cooked resister.
also I am not getting a reading on the resistor pointed out in my last pic.

having a hard time identifying part numbers for the components on the board. example Q22. Nothing in the manual really gives this info or values of resistors either.

I'm going to search pinwiki to see others is anything there

that's fantastic!

thank you!

perfect. I'll work on it tonight. hope I have the parts on hand.

How many OHMS? 82K ohms + - 5%???

Thanks again!

Having trouble finding Diode 1N5275A..... all I can find is Part Number 1N5275B

Had to order some parts.

Where are you getting your 25k pots from (or recommentd) when you're buying multiples? Id also like to order some 1N5275A to have on hand, GPE doesn't have them.

Thanks again

this is what I sent with. thank you

Replaced all the high voltage components and displays work perfect! thank you for all the help!
