I think everyone would, but better than having a dead game.

Yep me too. And one reason I have a spare NOS WPC-95 A/V board. But if I had to use an aftermarket board to get a game running I definitely would.

So much talk about people wanting to buy a spare board. I'm not hearing too much about getting original boards repaired.

It will be good if someone can take some time and ask around and make a post of all the people/businesses that will still repair this board. I would hate to hear of any board that gets tossed out instead of being sent out for repair just because of a replacement board was bought. I do hear some people actually toss boards in the trash, not knowing who can repair them.

Some I am aware of who do repair this A/V board.

Though, there bound to be someone who repairs boards on your side of the world. Check with Robin, as he lives in Holland, to see if he knows anyone.

If anyone is having an issue with their A/V board, post some information about the failure. If it is DMD related, include the voltages that are on the power connector to the DMD.

That would be great if you could bring brand new boards to the market.

One of the failures is the two small black capacitors (C28 and C42) on the board.
They dry up and do not regular voltage correctly.
This was an under design from WMS similar to problems that occur with age on WPC PDBs.
Many times this is simply a failure due to heat from use of the board under commercial conditions.
I have seen quite of few cap sets replaced on this board since 1998.
I need to look up the schematics on some of the other basic failure of components that get fried.
As long as the ASIC chip and few other components are not completely jacked up the board is repairable.
Tracework on this board is delicate, and heat and age do not help matters.
I again caution repair of this board is not for novices.

I would gladly buy 2X replacement tested A/V boards for $350-400 each, which would be my limit for costs of production of new board.
That would be equitable if produced in sufficient volume for the work required to manufacture the PCB.
I don't see a production run being large enough with available parts to be able to get the cost down below $250 as the ICs are just to damn hard to come by overall. Nobody has used this for over a decade+.
In about 5 years, we will be exactly in the same position we were with WPC games in 2001.
If a manufacturer wants to "tool up", I would enjoy seeing a working prototype based on Ed's work.

About six years ago I had DMD voltage go out. Can't recall which voltage of the three. Bought my desoldering iron specifically for the purpose of fixing this expensive board. Paid for itself right there.

Only repaired the one voltage circuit and left the other two unmolested. Still going strong, so far. I had some board repair experience with an old fashion solder sucker so not a total newbie. Definitely do not recommend working on this board as your first!

Eric

Did you replace the MPU board? Try reseating the ribbon cable on both ends at plugs into the left side of the A/V board and to the MPU board (looks to be the top right side).

Push on the ASIC chip of the MPU and any other socketed parts.

Do you have a friend that has a WPC95 game that you can verify the A/V board is faulty if either item above does not help?

Do the ASICs on the AV board fail that often? I haven't come across a failure before. 90% of what I see fail on that board are the C28 and C42 caps.

For a sound issue?

No, those caps are for rolling DMD issue which I've encountered a decent amount of times. Just curious to the rate of failure others have encountered with the ASIC on that board.

Yeah. I fixed a Congo for that issue 5 years ago. I forgot what part location those capacitors were.

Try pressing on different chips/parts of the board and see if that changes anything. The audio in my Congo was cutting out and would work if you pressed on the left side of the board. As soon as you let off, sound would cut off. I think it was the asic chip that needed to be resoldered.

Would anyone know why the 501 fuse would immediately blow on power up on this board? Thanks in advance. I'm finding very little if any info on these boards.

Possibly one of the bypass capacitors is shorted? That or the audio amp is cactus?

Sounds like you need to send it of to a board repairer if you have limited electronic repair knowledge. I wouldn't mess with it as you might introduce an un-repairable problem.

Homepin,
Thanks for the reply. Last night I started poking around a bit with a meter and found that diode D20, which has a trace to that same fuse (501) is reading 000 whereas the others 3 (D19, 21, 22) are all reading around .490. The only symptom in the game is a VUK firing repeatedly, which I'm not sure is related to that yet (one problem at a time). I do have enough repair skills to replace diodes, transistors, etc. but really no skills in diagnosing problems on boards. Thanks again!

Great. Did you find anyone on your side of the world to repair the board? I'm not familiar who repairs boards outside of the U.S.

Haven't heard of Ron before, does he do good work?

As for me repairing these boards, not a problem. Should have enough parts to keep up with repairs for quite a while.

I'll definitely echo what's been said here, this is not a board you want to test your skills on. It's very delicate, ultra fine traces, and getting more difficult to find replacements all the time.

Sorry Rob. There isn't a spell check on people's names.

Well at least the N and B are right aside each other on the keyboard

Apparently using an older WPC board for DMD functionality works--according to @mocean.

Using a PinSound board to bypass the audio circuit on the AV board on WPC 95 machine absolutely works--have done this with Monster Bash, and am still using the AV board for DMD functionality.

So apparently using a combination of an older AV board for DMD plus a PinSound for audio, you can completely remove the AV/95 board. The only thing I haven't seen/heard confirmed/done for this is using the older boards for DMD on WPC 95.

So, where can we find now WPC-95 replacement AV boards?

No guarantees you will find any more new ones. Have an original that is not working? Send it to Rob Anthony for repair.

That's a long way from Rio....

There was the workaround to use a WPC-89 DMD board with a pinsound board to replace a WPC-95 AV board.

Now that's better news!

Where can I find detailed instructions please?

Buy a PinSound and an old WPC89/WPCDCS Dmd Board. Completely remove the WPC95 A/V board.

Hook up the PinSound per their instructions. It’s not hard but it is a lot of steps. You may have to get creative with where you mount it.

Hook up th DMD board and connect the remaining DMD ribbon connector to that board, plus power. Done!

Well.... THANKS!!!!

There has bound to be someone who repairs boards on your side of the world. What issue do you have with it? If it is high voltage, you can repair that yourself if you can solder. There is a kit of parts available for it.

I have a very limited supply of both new RD WAV095 and original repaired WPC95 A/V boards. Fair warning, neither are cheap, email me directly if interested.

I have 10 Brand new wpc95 AV boards

new components on NOS boards

Nice... you can make alot more also correct? Do u have a website to order from or check prices?

Rottendog is now making their version again. They are in stock.

Where?

And Thanks Wayne, Ill check it out.

I have a Rottendog A/V board, $380 shipped.

Big daddy has them on ebay
