Hi

Super that the G-loc is back to life :)
I am glad that my L2 transformers worked.  :-)=

Also great with all the fine detail in the restoring process, that might be handy to know someday  ^-

Kind regards
Per

Another thing - after i have reset all the options in the menus i do not longer get the ADSP error at startup?!?!?

So definitely I need to fix red color now  :-)=

Well some status - it seems that i can test the ADSP board in the test menu, so i have tested it - but impossible to see anything without the red color.


So i think that i need to fix the red now :)

Hi

Thanks :) - I hope that i can find out why the ADSP board is not working. =?=

My best guess at this time is to change the caps at the  APU PCB - it gives the main PCB its +15V, -21V.
I do not know if the fault is at main pcb or the ADSP pcb.. but i am thinking that it is the adsp board, because of the missing led's

As I could tell the caps i changed at the three "game boards" where the original ones from 1989 - so It might be a good idea to change all caps on the other boards too :)

I have some more Documentation here if you can use it

Hi

I have a Hard Drivin upright that i am trying to restore

I now have managed to get the screen working (Intervideo chassis) - the issue where just some bad solder joints.
I still need to have the Red color fixed, and a new capkit.


Now i can see what the game does at startup, so before i put more energy into the monitor, I want to get the game working

When i power it on it first says that brake pedal is out of adjustment, but I can turn key to continue.

Then I get this message "ADSP timeout error"
A small video

If i look at the diodes at the PCB the most of the lights lights up, but no light in the middle PCB does not light up at all, and that is the ADSP board, if i test the 5V at the 5V test point at the board it is 5.3V

A small video
Things i have done
1.I have put in a new 10A power supply for the 5V, and adjusted the volts so that i have 5.3V at the 5V test tabs on the board.
2. Replaced all the caps on all the game PCB's -> my log can be found here https://www.dropbox.com/s/0n1nutecz4...0log.xlsx?dl=0
3. Cleaned all the socketed chips on the boards.

A note regarding the new power supply - according to the documentation i can find, there must be two sense wires (red/stripe and brown/stripe)
All my wires are red or brown with no stripe, so i have connected them all to the new power supply.

Documentation http://www.jmargolin.com/schem/HardDrivinSchem.pdf

If I test the 12V at the testpoint at the multisync pcb I get 11.5V a little low - I do not know if the ADSP board uses 12V? - there is no 12V test points at the ADSP board.

Do you know where to look to get the ADSP board working, get the LED's to light up? - if you do give me a ping :)

In summary, it seems that the L2 transformers from Per are good  ^-^
Thank you again, Per, for getting the transformers made and sending some to me. I can't thank you enough  8)

The golden rule is to check the filter capacitors, or just replace them if there is any doubt. I found out the hard way, and spent a lot of time looking for a problem which turned out to be quite simple  :-[

It might be worth checking or replacing all of your small electrolytic capacitors (eg. C13, C28, C30, C25, C26, C27, C19, C20, C21, C36, C18), it might solve (or prevent) all sorts of strange problems  :D

Next step is to put the triac back in, as well as the OP-AMP and 5V regulator for the logic circuits.

Cheers for now.


Hi

Whau - nice job  ^-^ and I am happy that my L2 transformers are working  :-)=

I have just looked in my excel sheet from when I tried to use one of my L2 transformers, an ran into the problem with low 15V.
As i can see I had changed C28 and C30  them to new 47uf... but I need to check visual at my two "spare" power supplys, if I have mounted 4.7UF... I can be... 

Nice work restoring! - also all your super discovery If just I know how to use an Oscilloscope  :D

Hi

I told them that the 15v where low, but i do not know what they have changed, I also asked them for the datasheet for the new ones but i newer got it.

They wrote that they have changed the number of windings on the 15v side.

Hi

Super that they made it to you, and also relativly fast  ^-^
I hope that someone have a solution for the low volts issue.
Love to follow your repair  ^-

Hi,

Wow !! Your gameroom is fantastic Per !!  :o

Pinballs, dedicated cabs, including sitdown race cabs, a cocktail table, a pool table, pachislots, etc !

It's so varied and so well arranged ! Your bar corner and its jukebox is awesome too ! ^-^

You must be very proud and vey happy with such a nice gameroom : a complete success !  :-)=

Thanks  ^-^

Hey that's a nice game room !


Hi

Thanks  :D I am also proud of my room  :D but i need more space.

Super to follow your repair  ^-- I hope that the L2 transformers arrive soon.

Your IC 9-10-11-12 (78L05 / 5 volt regulators) might also be dead and give over 5V
I have learned if they put out over 5V then the PC910 might also be fried, and need to be replaced.

Also remember to test the big diodes, the Q19 and Q22 seems always to be the one who go bad first.

Just some tips - my last restore (https://www.gamoover.net/Forums/index.php?topic=40992.0)

I have put some (TO-220 Heat Sink) on the Q20 and Q22 (K1250)


I think the missing cooling causes them to blow up.
So get some heat sinks and termal grease and mount them  ^-^

Also if you change the PC910 - then get some DIP8 sockets, and put the new PC910 chips in sockets, then they are easier to change next time.
(hopefully there will be no next time) :)

And my G-loc still runs  ^-^

HI

Yes I got some L2 transformers from China - but the first ones I ordered i only had around 12V at the testpoints where i needed to have 15V.
All the other voltages where fine, just the 15V where around 11-12V and i do not now if the 15V is needed...maybe GC339 can confirm is 15V i is needed, or 12V is fine?

So I had order some more from china, but i have not tested them yet, so I do not know if they are OK.



I will send you two completely free, if you just pay for the shipping. ^-

Just send me a PM with your address, and i will try to figure out what the shipping cost could be.
I hope that you get your G-loc up and running - I would like to see some pictures of the restoration process. :)

Nice work  ^-^

Is your Rad mobile still working after you did the second repair to your power supply?
This time i have mounted som cooling fins on Q20 and Q22 (K1250)
On my there where none, I am thinking as it where the K1250 who where dead, it might be caused by heat.
