Title: Bally with Tatung Monitor issues
Post by: rjpohl on July 11, 2023, 04:09:30 AM

I have (3) Tatung L20XX monitors that all have the same problem of no video.  They do give the no signal message when powered on, the light on back of monitor changes to green but there is no video.  Is this a bad AD board or something else?  Caps look good on the AD board.  I have a 21" monitor that is working in the machine so I know it's a monitor problem.
thanks
Bob

I have this issue on a couple of monitors. WMS and IGT... it turned out to be the board the powers the LED backlight. You can verify this with shining a flash on the screen and see if you see an image from the slot. I replaced the boards and they worked again. Or you can recap that board.
