Title: monitor out
Post by: roberts1k on September 06, 2006, 08:05:25 pm

I Have a Golden Tee Rebuild.  I was playing and about the third hole the screen went black.  I still have sound and the game works minus the screen.  I opened the back and with canned air blew off the monitor chassis.  I did get a picture back with lines through it.  It then went blank again with a horizontal line down the middle.  I thought a chip on the chasiss wasnt seated correctly.  It is a GWEC chassis from 1983 board.  I tried to reseat the chip Lettered IC on the board and labeled NEC JAPAN PC1397C      890IE.   The chip prongs broke and I cannot reseat it.  I am assuming it will affect the monitor, but not make it display at all.  The neck bulb is not glowing either.  I dont know if it was or was not glowing before I reseated the chip.  The chassis is 23 years old.


The monitor is a-WGE1972-H0GS39L/K7200  19

Based on what I read, my guess is the Horizontal output has blown... may have taken out the power supply.

I could not find an NTE repalcement for the part#'s you gave so it is hard to say what comes next.

I would not spnd a lot, the monitor is old... we do not carry 19"CGA as there is no way to compete with the cheap offerings.

I would suggest you contact Betson.

The monitor is not old the chassis is.  Should I replace the chassis?

A Wells-Gardner k7200 series that's 23 years old???????  Something's not right here. The 7200 series is not that old. I think it was introduced in 1996.

if you have a horizontal line then its a bad solder joint on the fly back or around the frame i/c,scan coil plug, 25volt line or a faulty frame i/c or missing 25volts to the frame i/c

I am new to this.  Does that all deal with the chassis?  Should I send it in for repair?
