Title: Gamemaker monitor question Post by: keystone9 on July 16, 2013, 04:39:14 PM I am working on a Bally V9000 Alpha Gamemaker HD with a Tatung L20XX touch screen monitor. When I power up the game the monitor is a little distorted but after a few minutes it clears up fine. Sound like to me a weak cap but really not sure which one or if there is something else. Thanks in advance. Bill

Title: Re: Gamemaker monitor question Post by: keystone9 on July 18, 2013, 12:15:44 PM Is that board mounted on the monitor? Thanks.
Title: Re: Gamemaker monitor question Post by: Neonkiss on July 18, 2013, 05:37:35 PM Should be inside the monitor. You did say it was a 20" Tatung LCD?
Most of the Bally's that I've had are the Tovis monitors. I can check and see if I have the manual for yours if you post the complete part number. Title: Re: Gamemaker monitor question Post by: keystone9 on July 18, 2013, 05:54:11 PM P/N 7000236 Rev. A. Thank you.
Title: Re: Gamemaker monitor question Post by: Neonkiss on July 18, 2013, 09:38:12 PM Sorry, Maybe I should have said Model Number.
I know you said it was Tatung L20XX but do you have a complete model number? Title: Re: Gamemaker monitor question Post by: keystone9 on July 23, 2013, 01:35:23 PM L20LA41E2W53A04. Bill
Title: Re: Gamemaker monitor question Post by: Neonkiss on July 23, 2013, 07:13:33 PM Sorry, I don't have that manual. :60-
But I do see the AD board listed on Slot Doctors web page. http://slotdoctor.net/ADBOARDS.html (http://slotdoctor.net/ADBOARDS.html) It's inside the back cover of the LCD screen where the input to the monitor attaches. I have not worked on this particular AD board, but most have 4 or 5 caps that are around 470 uF @16V Check your board and look at those caps.

Title: Re: Gamemaker monitor question Post by: eferry on February 11, 2014, 02:59:14 PM I am having the same problem with my game maker HD. I have ordered a new AD board from Happ back order. it is now 6 weeks waiting. I am also having problems with my sound. It seems the the top speakers do not work only the bottom. I replaced the audio board but that did not correct the problem. I see there is a power amplifier could that be the problem. Any help would be appreciated. Thanks
Title: Re: Gamemaker monitor question Post by: eferry on February 20, 2014, 05:21:09 PM Game maker HD update. I finally received my new A/D board. After the new board was installed the monitor is distoration free. Make sure you solder the 2 pin connector on cn303 from the old board to the new board. Be Carefull not to pull off the connector on the touch screen. I did that and the touch screen did not work. the new part # 2120124/ L20LA41M2W53A04.
