Hi Purchased a daytona usa 2 twin cabinet recently, was working great but turned it on tonight and once its ingame a bit its showing green lines on screen. CRT test etc in test menu looks fine with no problems at all and the green lines dont show up untill its showing graphics on screen really what could be the issue?
Just wanted to add, did a memory test and everything is fine except for video ram which fails, says IC81,IC91 and IC99 im not really sure what this means, does this mean I need a new video board? I'm not even sure which board is the video board or where it is
I'm by far no expert but corrupted video RAM would result in garbage being thrown up on screen when the game is being rendered. I'd suggest taking some hi res pictures of the board itself, post them on here (make sure their clear pictures), and I'm sure someone will be able to point you to the ICs which are at fault. There's a little information on this page: http://www.aaarpinball.com/Daytona2/daytona2.htm Sounds like the ROMs themselves are fine, and the RAM might be replaceable (though it may be soldered in which will require someone with experience to replace them), though like I said before I'd get a second (more informed) opinion on that one.
My Silent Scope had similar issues. It also had a faulty RAM. I don't have any experience with Daytona, but I'd assume it's also SMD RAM on the board. You can probably get new replacement parts OR desolder them from a graphics card or old network card or something. - really depends on the parts. The board is probably labeled so you can find the ICs in question. If you don't want to invest into new parts you could try resoldering the old parts or check for loose pins.
You'll need to get the video RAM replaced. Locat those IC locations on the video board and then look up the part #s. Had to do the same for a Model 2 Motor Raid recently.
This seems to be pretty common with Datona 2, I have a friend who has 2 boards hes eventually going to send me to replace the chips.
its a shame, only owned it for like 2 days before this happened! talk about bad luck Ill look into either getting new video board or new ram chips
This seems like a widespread issue on boards like this judging from the responses, is this down to lead-less solder or something you reckon?
Interesting, I didn't think they were using the crappy solder back then, though I assumed it had something to do with heat build up since those things were on all day every day.
Just to make sure, it is safe to turn on and off via wall socket? I assume it is since switch on back of machine will do exact same thing basically
Should be fine since using the power outlet to turn an arcade on and off was standard practise, at least for the ones I've been in when they were opening up.
I think my machine is cursed, noticed today that network wasnt working anymore. After an hour or so trying to work it out i found out the toslink fibre cable was somehow faulty.....wtf is the chances that the toslink cable would become faulty like 3 days after i brought it!! video board and toslink failed in last 3 days
The cable could have been bent during transport. But it might be something else - Check the voltage of the PSU after transport to avoid more damage. I'd believe the manual setup procedure also tells you to do that. My arcades also had the wrong voltage adjustment after transport. In case you didn't do this yet, also check the fuses. Some idiots short their contacts instead putting in fuses. Also check the fuse-types. Also, thinking about it, the video issue is probably really only related to bad solder joints if the video worked fine the last days. So before ordering parts you should just try resoldering.
yeah i found it, its in the metal cage under rom board/cpu board etc. I did look it over and couldnt see anything obvious as a problem
Check each pin of the ICs in question individually: Use a magnifier (or camera in macro-mode or something) to look at one pin at a time, then use a small screwdriver and slightly put pressure on the pin - if the pin moves it should be resoldered. Also make sure that the traces on the board are not coming loose - sometimes traces break off near the soldering joints. If the IC is not SMD you should look on the underside of the board too. You should also check if the traces are running anywhere near a battery (also think about where the boards used to be) which could have leaked in the past.
sorta out of my league, even if i had replacement ICs (which I don't), but theres like 40 pins and they are like less then 1mm apart....my soldering skills suck ill just get replacement video board then send this one off for someone else to fix
