PLS HELP! Punch-Out PCB - Jail Bars & No Boxers on bottom, top is perfect,

hello guys, hopfully someone knows the cure to a problem im having with a new set of Punch-Out pcb's that i just got.

Well everything was all messed up bad......

I inspected the 3 boards, 'CPU' - 'VIDEO' - 'BAK'

and i found a 5 of the ceramic disc capacitors that had cracks or chunks taken out of them, so i replaced them, also i replaced the 3 220uf 16v Ele Caps on the 3 boards due to them having crudd on them and figurd since i has the solidering iron out i would replace them,,

Then i try them out and this is what i get when i turn it on...

the top and bottom does not disply the NINTENDO PUNCHOUT !!! logo
but the bottom monitor does display the nintendo copywrite
then i got to try the games and this is what i get

TOP MONITOR: Everything looks GREAT!! The color is PERFECT!! And the sound is there!

BOTTOM MONITOR: This is the bad one... :( i get Jail Bars across my screen, the picture kinda looks like there is wayyyy to much blue color in it, no sound, and no boxers [no glass joe]

now i do have another set of working punchout pcb's and thoes work perfect so i know this has nothing to do with my monitors its in the pcb's

also when i put it in service mode it says that everything 'ROMS' check out OK

So now im not shure what my next step is... anyone know where about the spots that i should look for damaged componets are?
And i did allredy replace the ones that cought my eye..

So whats do i do now...

Someone PLS help!

I need a KLOV doctor to fix my problem!



attached are some pictures of my prob....

yah thats correct,,, also no boxers, no sound, jail bars... so what do u think i can do now? could it be the ROMS or something diffrent?

what ROM CHIP displays the red? maby a broken component around that, idk
 
troubleshooting

First check out the basics: http://www.priglmeier.com/arcade_projects/game_boards.html

Turn on the DIP for power on self test (POST) SW2 DIP P with the power off then power on the unit and watch the display for messages.

What does the display show?
Download the PDF of the PO manual.
Check the power supply voltages.

Post the results and pics.

WOW nice site, thanks for that.....
yah i did a RAM test with turning on the last dip switch..

and it told me that everything tested fine.. but ill post some pictures here sometime tonight...

the power supply is perfectly fine because i have a 100% working punchout pcb that everything works 100% when i use that one.. it just with this dusty other punchout pcb im having probelms with...

Anyone know what components are used on eather of the 3 boards for the color RED display on the lower 'bottom' monitor...

thankxxx
 
ok.. well messing around with the 3 pcb's... I fixed a few of my problems...

MISSING RED : This was caused by a *BAD* '7-E' Color PROM from the BAK board, I swapped this PROM with one from my 100% working PO board and now i have RED

BOTTOM MONITOR SOUND: This is caused because im missing the 'RP 2A03 CPU' chip

so... now all that i need to figure out is how to fix the JAIL BARS then this board set is 100% fixed!! Anyone know how to fix jail bars??? also BTW it is not my monitor!
 
WOW!! I just fixed another problem!!!!!!!!!!!!!!!!

BOTTOM SCREEN DISPLAYS JAIL BARS: This was caused by a bad '8P' EEPROM on the video board... '8N' was also tested, '8N' passed all tests!

IM DAMN GLAD i decided to start swapping out chips!!

So now i guess my next question is does anyone out there have DUMPS of any of there chips

8-P from Video Board
7-E from BAK Board
2A03 From CPU Board.. Does this chip require to be burnt / does it have software on it?

By someone helping me with the dumps it would be alot of help since i do not have a burner, but i do know someone who can burn the chips for me for alittle $ here on the net, but they need the dumps...

If anyone has the dumps could they please send them to my email? [email protected]

THANK YOU to anyone who send these, and to all who have helped me with this!
 
wow i didnt even know about all that... but yah i have maid up for it, and thank you for the info for mikesarcade.com.. also thats awsom that the mame roms has all the rom dumps! i never knew that, iv allways used the mame app to load the zip and i have never unzipped them befor untill now, and damn alot files in thoes zips... thx again!

omg guys now comeon, when we make a deal here by pm, and then after 3-4 days of no responce back from the person you pritty much think the person doesnt want the item. iv had alot of deal go bad due to people not replying back to pm's.. like i just paid for a pc10 pcb and cp for a single monitor. i sent the $ to him and he said he shipped it out.. 11 days later i havnt recived anything yet, and he has a problem replying to pm's.. i guess all i can say is you should of sent me more pm's and not of waited 5 days...

im a good guy and i like to give deals, and also in my defence i was never informed apon there was/is a set of rules for selling here.....

the whole thing about the price being raised from $25 is because someone here said they needed it badly and offerd me $40 for it... and since there was not any confirmed deals on it i pmed the 1st person who pmed me about it and asked if they would match it/offer for it.. and they didnt

and there were never any deals maid to no one about this, after a few days i did agree to the person who offer $40 because no one matched this deal, and i gave time for the 1st emailer to respond back befor i maid the deal @ 40..

also i dont have alot of money so i would want the best price that i can get. but if someone did help me with something i would give em a good deal to help them out in return..

sorry if i pissed you off pacry but i guess you should of sent me more pm's... but i totally forgot all about you.. and i had alot of diffrent pm's comming in, iv spent over $1000 buying parts here from users, and within the month that iv been here i have 149 pms in my box and 127 posts iv maid.... i send out atleast 10-15pms a day here, and then atleast 5-10 pms on ebay, and another 10-20 emails a days, so things can get sticky here for me at times..
