New Life Games Tech Forums

I need some help; my Game King quit working last night.  I installed a new I-game and after the Installation I lost all video and lights on player buttons. Although I do have lights on award, belly, CPU board and side display.  Jim suggested using a spare power supply or monitor which I have neither.  I'm open for any suggestions on how or what is needed to fix my machine.  I do have two S2000 machine but, not sure if power supply would work in the Game King to check if that's the problem. Any Help! Will Be Greatly Appreciated!!! Thanks Freebird4

How did you install the new game?  If you removed and replaced EPROMs chips check to make sure none of the pins got bent during installation.  Also make sure that you didn't plug any of the EPROMs in backwards. 

Have you tried changing it back to the game that was working before the change to see if that still works?

From the video perspective do you still have power to the screen....??

I am going to make the assumption you have a tube monitor. Tube TVs/Monitors have a high voltage static charge and when you run your nuckle across the screen you can feel the electricity.
If its LCD turn off the lights in the room and look at the screen with a digital camera it will be bright regardless on how it looks to the naked eye.

If you have no power - start checking fuses with a multi-meter .....

I just got home and checked the LCD with my digital camera, the LCD was dark, I couldn't see anything at all.  But while checking the LCD my machine started the beeping process stage when new software is installed, but I couldn't see anything on the screen. Do you think my LCD when out or could it be another problem?  Thanks for all of the suggestions NLG members.  Freebird4

Don't forget to check the pins at the back of the board to make sure none of them got bent, this happens.  I know someone asked this, but did you try your previous game set back in it?

Here is a pic for reference, not sure where I got it from  :96-
Thanks,
Wayne

Wayne, thanks for your help!! I double checked all pins to make sure none were bend. Everything powers up except the LCD, when machine is first turn on the monitor flashes a little bit of light and then nothing else.
I have noticed lights on back side of LCD are on but nothing else! I now believe my LCD has went out, but not for sure don't know how to check except for connections. Thanks for you help and input!!! Freebird4

It would be pretty unlikely that the LCD display would die at the same time that you changed games, but hey, strange things happen.  Most LCDs have digital controls.  Check and see if yours has a menu button, if so press it.  If it brings up an on screen menu the LCD is most likely good.

I beleive he said "No lights" in the buttons....MPU is not running...

I believe no lights on player buttons are due to new game install, which hasn't been completed due to no video unable to complete setup.  Correct me if I'm wrong with new game install must go through setup before button will light up.
Thanks for all of the input and suggestions NLG members. Freebird4

look at it this way....
Machine worked until he did a game change.....
problems with ANY of the chips will result in a failure message EXCEPT the base chip!
Cause...
1> base chip is in backwards
2> basechip has a pin bent
3> basechip is bad

A bad Cg card will result in an error
A bad PXL card/chip results in a error message
A bad Basechip results in NOTHING


Hope this helps!

P.S. what did it do when you ran the clear chip?
Run the clear chip again and see if you get anything on the display

Kirk

Hello Kirk,

I run the clear chip again and still didn't get anything on my display.

I appreciate all of the suggestions!! I have double checked all pins none bend, made sure that all eproms/chips are installled correctly. I did a check with my digital camera with no luck no light seen. Doe's anyone know of a repair shop in Texas that could look at my LCD monitor and check out? Freebird4

When you ran the clear chip did you see the TWO LED's lit on the MPU board? Also when you try to power up the MPU do the resr of the LED's show any activity?

Hi, which clear hip did you use and with which game?

I have used a #22 clear chip and also used a #40 neither one did anything.  When I have the key chip in I only see the last three lights on the MPU board, I don't see two led's at all.

Key-22 is for 3902 series MPU..if your Gameking is a 3800 series you should be using a Key-17...
Key-40????
You mean a KEY-45?  WRONG chip....

What is the name of the game that you took out? What is the name of the game you are switching to?

I have 3902 board in machine. Sorry I didn't mean a #40 only a #22.

I use key 40 on them and it works fine.  from my notes, key 40 replaced key 22 and is backwards compatible, it says key 22 won't work with 044 games.

Thanks,
Wayne

I'm pretty sure he said he gets the machine siren noise that comes on when you first boot after a clear, from all posted, it could be a fluke that the lcd died at the same time, this would have been the last thing I looked at, but could happen. 

w

Hello Wayne, yes you are correct!  I get the siren noise after a clear. I have switched out games, Key chips and etc. I still don't get a display no matter what I have tried! Guess my LCD has died!
Anybody know someone in Texas that repairs LCD's? If you do please let me know how to contact them.  Anybody have one for sale?
Thanks, again to all of the great NLG member's that have made suggestions on how to solve my machine problem.   :244- :244-   

I just have to get it fixed can't live without my machine!   :8- :8- :37- :37-

Thanks, Freebird4

what make/ type/model of lcd do you have?

Thanks,
Wayne

Brand is a Kortek model# is KTL170S-01  monitor is 17" touch screen.
Thanks

I have read this entire thread.  It sure is strange you had a complete working  machine until the game change-- :103-.  I find it hard to believe your lcd took a dump in a game change unless it got spiked somehow.  It is possible but not likely.  Just my 2-cents.  You probably do not need a entire assembly any way sounds like the pwr supply for the lcd if that is indeed the case.

Barry hit on what I was about to say.  My conversion monitors have a power supply that plugs into the back of the lcd, mine are door mount WG units.  It does sound like yours isn't getting power.  I'll see if i can find anything on it.

Thanks,
Wayne

Richard,  Post a few pics of the BACK of your lcd for us.  We may be able to help if indeed that is the Problem.  I have some kortex stuff here that is new but I need to see EXACTLY what you have.  Also as a note I would re-store this game back to it's orginal working condition and get the lcd back working.  The other game kit has not been proven out yet. Just my opinion and I am not an expert on this platform but I think you have other problems going on as well. Barry.

I think this manual should cover it, looks like 12 volt power supply.

Wayne,  Great posts,  I scanned quickly thru both of them.  I think the invertors in the first post may be an issue- :103-.  B.  -Richard,  For a "Small" fee bring/ship me the game and I will repair it for you with your desired game change-- :96-. B.

Thanks Wayne & Barry, my green led stays on doesn't blink! I will post some pics.
Richard

I have attached some pics of the inside of my  LCD monitor. Hope this will help, Barry and Wayne

Hi

Even with no signal from machines the LCD should still display no Signal or something similar when powered up. If you have an extension harness of some kind and a multimeter check if there is power from the power supply.

Ian

Forget Key Chips, Boards and Software, and Replace the Power Supply on the back of the LCD, 20 to 1 odds, any takers? or if you don't believe me I will send you a monitor to put in it and show the bet results

I agree,  they have a known issue also as indicated in the link that was posted.  12vdc.

W

Sorry guys we have had a family emergency. I know are of you are the experts all that I am trying to do is learn. I'm sure Jim is correct, he always is!!.  I will try and locate a power and post a update once I get it installed.
Thanks again for all of your help!!!!  :244- :244-  NLG members!!!  :244- :244-  Richard

Richard,  As soon as we thaw out here I will look for a pwr supply.  I thought at one time I had some new ones.  That being said keep your feelers out elsewhere-It probably would be good to have a spare anyway.  Later B.

Barry, thanks Jayne is working on also. Richard

I should be getting power supply next week and I will post results.
Thanks for all of the suggestions from NLG members.  :3- :131- :3-

I know I'm kind of late posting on this one, but the power supply displayed has three weak capacitors in between the large heatsinks...C825, C828, & C836, out of twenty repaired power supplies replacing these three capacitors has brought 16 back to "life"...C825 & C836 are 1uF 50V...C828 is a 47uF 50V.  I know you've already ordered a power supply, but with a couple dollars and a little time you can have a spare...

The best thing you can do for the monitor is leave the metal cover off of the back of it, all it does is keep the heat on the boards & with the monitor installed in the game there is next to no chance of touching anything that would shock you.

Good luck & God bless,
Mike><>

Mike, thank you for the great information! Great to learn something new that saves repairs!!!! Bet other members on NLG will gain life on there LCD's and power supplies using this great tip!!!!
I will now surely leave the back cover off of my LCD now!! :3- :3-  Good Karma and God Bless!!!

.B --K+ Good Luck. --- :88- :71-.

Still waiting on a replacement power supply! Will update status of LCD monitor once received and installed.  Thanks

did you look at the link that was posted?  you can likely repair it yourself.  Probably faster than the slow boat.

W

Thanks Wayne, I did review the link. Somehow I was send the wrong power supply replacement I was sent a power supply for the machine and not the LCD.  I would like to repair the existing power supply, but I'm not sure where to buy the replacement capacitors and correct part numbers.  Mikes post gave me the numbers and where they are located. Thanks for the information! Freebird4

that same info(locations and part specs) was posted in the link as well as some other troubleshooting tips, perhaps you didn't scroll down,  not that that matters anyway.  There should be an electronics supply store somewhere near you that would have the parts, or theres always digikey or ebay.  Hopefully your new P.S arrives soon.

Thanks,

Wayne, thank you!  I will try and fix myself once replacement is received to have a spare.

Well bad luck has struck again for me! I received the new power supply today, just got home and installed same problem no display!  :37- :37-   

Ok, how about I send you a CRT to diagnose the problem between the Power Supply and Monitor, just need to know if the Monitor is a 19 Pin or 25 Pin connector, I know I didn't sell you the LCD, but I am willing to help you

Thank you for the offer to help me figure out what my problem is! I will gladly pay the freight on the CRT! I counted the pins on my monitor and it has 21, counted pins on Game King plug and it has 19.  Dumb question is this correct? Maybe extra ground pins! 

Update on LCD monitor: I have replaced power supply for LCD and latest I have replaced power distribution module and still have no video on LCD display.
Any other suggestions on what else could be my problem would greatly be appreciated!
I'm at a ropes end, I admit it I'm a slot machine junkie and I sure miss playing my I-Games!!!!!!!!!!! :8- :8- :37- :37-

Thanks to Jayne at US Gaming replacement monitor is on its way to me!!!!!   It's really nice when people follow through with their promises.
Hats off to a69mopar, PWRSTROKE, Belbtech, TZtech, Karaoke Mike, KirkLasVegas, Tilt and Jay for all of your input helping me solve my problem!!
Thanks Again Guys!!!!! :3- :3- :3- :3- :3- :3- :3- :3- :3-

That's good to hear, please let us know when it's up again.

Thanks,
Wayne

Machine back up and running!!! Thanks again;  a69mopar, PWRSTROKE, Belbtech, TZtech, Karaoke Mike, KirkLasVegas, Tilt and Jay for all of your input helping me solve my problem!!

Freebird4       

Richard,  Glad you to hear you are back on-line-- :244-.  Now go and enjoy your game---B.

What fixed it?

 :3- :3- Glad you got it going again freebird4!  Post a picture when you hit a royal on it!

It's great to hear it's up and running again.

Thanks,
Wayne

A replacement monitor fixed my problem which was supplied by Jayne at U S gaming. I replaced every power supply in my machine and the one in the LCD monitor which someone bet me was the problem. I even replaced the back pane board in my machine. Guess this was a good learning lesson for me, now I can trouble shoot a machine from top to bottom!  Thanks Again to the ones who gave me idea's and input trying to help me solve my problem.  :3- :3-

Were the power supplies known to be good and tested or were they used?  The common failure of these monitors is the power supply, it's easy to find another bad one from a used monitor.  I (or Bunker also I bet) am a bit adventurous and would likely swap the power supply with the known good one to see if it still works, if not then it was bad.  Most people would just try to enjoy their game and I respect that also.

Thanks,
Wayne

P.S.  I do like the Elvis avatar.

Wayne, the know power supply was brand new and not used!  It was ordered from American Gaming & Electronics in Las Vegas.  Cost was just about $100 bill with shipping.  The original power supply is back in the bad LCD monitor which will be going back to Jayne at U S gaming for repairs.  Maybe the new power supply was bad too!  All I did was install the new power supply in the LCD and didn't work after the installation.
