i tried changing a game and got these lines on the screen, they look like alien writing.
i tried putting old games and i tried clearing with chip in slot 10 and nothing changed.
does anyone know what i did and how to fix it
-
When you do the saferam clear, is the text legible?
-
Check the input connections on the monitor.
-
the text is the same.
i took the board out and put it in a different GM and got the same results.
-
Remove all of the game chips from the board and try them one at a time, you may find a game chip that is defective or is programmed for a wider, or narrower, monitor size (depending on the size of your monitor).
Re-seat your graphics chips they are to the right of the game chip sockets.

bartkoski What make and model machine are we talking about ??
-
A clear chip in slot 10 implies it is a Game Maker?
-
it is a 1997 multi touch screen with the v7000 board.
i tried taking all games out and doing a safe ram with dip switch 7 & 8 on, then all switched on, i switched monitors, i changed battery,its 3.6v
so i took out the graphics chips and put them back in, still same block images.

It seems you have another GM to use as a tester, I would switch out the mains and graphics chips, or burn new ones and try them in the board you are having problems with. It looks like corrupted/damaged programming on the eproms.

Also, I don't mean to be a smart*$$, but the game should be off prior to removing the MPU board.
-
better a smart ass than a dumb ass, the eprom's are games right if so i tried that
-
Do you have another machine you can plug the monitor into?

If you plugged the MPU in another machine and got the same results as listed in your prior post, then the problem is within the MPU. Now you have to see if its a software or hardware problem. The starting point is your Mains and Graphics eproms. You will have to switch these out with M&G's from another working Gamemaker or burn new chips from a working file. Then see if the problem is the same or fixed.

ok first i did M0 and M1 then G0 and G1. the problem one i'll call GM1 still the same scrambled words.and GM2 is working fine. is there a way to reset to factory condition.
-
should i do a safe ram clear after i switch the M&G's
-
yes
-
no luck
-
Then it is probably some soldered in chip on your board that went bad.
-
do you know of a place i can send it or is it something i can be talked through?
-
Call Larry 702-363-9998 11AM to 5PM PST.
-
thank you so very much for your time ill let you know how it went,
while i have you here do you know how to fix a two inch black line going down the center of one of my other GM monitors
-
Larry (I) also fixes those older monitors.
I just got a Tatung going that had vertical collapse.
Call Larry and send it in also.

i did a safe ram clear and pun old chip in p10 and took out some chips that were questionable, the screen was the same but in a fameral pattern, it looked like the set up screen, so i guessed at what it said and pushed buttons and turned the key to lock it in then restarted game and it came up normal but it wont take quarters or let me play. think ill try again before i give pu
-
i was checking the ohm readings on the resistors and wasn't getting a reading on one, down by battery and i was getting 5.4 volts on battery. think that's what is my problem?
-
If you read the battery with power on you may get that reading but with power off it shouldn't be more than 3.67VDC.
The battery should be a 3.6V non rechargeable Lithium Ion, did someone put a 4xAA battery pack in it's place?
See attached. No coin in may be a faulty options setup.

i asked this guy that has video games in this pizza joint at my night time job said that's what they call garbage and to take out all the chips remember where they go , use a soft brush and hold it under running water and gently scrub the front and back. then use a air compressor and blow dry it, wait a couple weeks and try it,, well i tried it and it worked...I'd like to thank everyone for all there input. :thank_you:

NEI (as opposed to TMI).
What make of monitor is it? Is the line Horz or Vert? Have you tried it in another machine to see if the problem is with the monitor or the board? Can you see the game graphics? Does the game play?
