Do you have, or have access to a FLIR camera? It would be extremely helpful in your business, easily locating warm circuits & components of analog design. You can also get a much cheaper version, that simply plugs into your Smartphone. A FLIR ONE GEN 3 is $200, then they quickly start increasing in price for higher resolutions. I'd think the basic would work for you. Probably find cheaper if "used" or "refurbished". Lots of computer repair shops and auto mechanics use them, too.

When the board is in "audit mode" because no battery is installed, Why do you have to reset the game a second time? I just confused what is "audit mode" when you put the pinball game in audit mode. When the CPU game board is first turned on its checking all the others boards and if the one or more chips is bad the CPU game board will "lock up". I'm not understanding if you don't have the "test rom chip" the normal ROM chip will have a built in BIOS test that will check the PIA chips, RAM chips, Lamp test, displays, coils drivers, etc and if anyone one or more is shorted or bad its will "lock up" the CPU game board?
@LyonsArcade

if you turn it off and then right back on fast, the 5 volts hasn't drained out of the capacitors so the game thinks it has the batteries installed and boots to gameplay mode.... you are correct, the board will lock up if the rom can't speak to all of the chips it's checking, it's exactly like you said. The test rom helps you figure out which chips aren't working properly... Thank you for watching Wayne as always, I know you watch all the videos, thank you!

Magic smoke makes people exited. My biggest puff of smoke came from a serial terminal driver/buffer chip that was inserted backwards by mistake (meaning, reversed polarity). The system was powered from a dual 5V@200A supply. Blew a hole clean through the chip, instantly filling the room with white smoke. Luckily, neglible damage to the socket, no damage to board or other parts of the system. Plugged in new chip, this time in right orientation and all was good again.

Yeah, when you see a digital logic chip go up in flames, it's always a good idea to go over everything with a fine toothed comb for any erroneous connections, or a broken wire laying in the exact wrong spot. In this case you found a possible original cause for it, so good on you, mate. Normally when a logic gate or simple buffer just goes belly-up on its own, it's not that catastrophic, so you end up having to pull out the scope or logic probe to find out which chip is getting input without outputting anything. (On the other hand, a chip that failed on its own might just get hot without actually smoking: I sometimes troubleshoot **LOW VOLTAGE** circuits by just touching chips to see if they get hot!)

A very basic ground question please. so when you test a volt on a board the red lead goes on test point say 5 and the other test point goes to test point say 3 or on the meatal. If you use the meatal back glass as ground at some point that voltage has to loop back up to the return wire on the socket? Is that correct? I mean I thought electricity had to loop. thanks .
@LyonsArcade
3 жыл бұрын
When you're measuring voltage, yes like you said the red lead goes on whatever the positive voltage is, and black goes on ground, in many games lots of things are grounded, which just means a lot of the metal is connected together. So on some games for instance, the door is grounded, the legs are even grounded, the side rails are grounded, the boards are all grounded, etc. So there is a ground test point on the power supply (which is where the DC ground originates) but anything that is touching that grounded metal part of the power supply is also ground. So if the power supply is screwed to the back box, the ground trace on the board is probably connected to the screw ,which is connected to the backbox, which may be connected to other things depending on how it's wired. Anywhere that is grounded can be used to check voltage. Thank you for watching Kelo!

Do you have a breadboard? You might be able to test some chips separate from the game (Not the CPU, RAM or EEPROM, but things like buffers and gates, for example) especially if it's a game you don't have a test EEPROM for. Then if you want to rule something out because you're not really sure, just jig up a mock circuit on a breadboard to test the chip and if it does still work, you can put a socket on the board (if it didn't already have one) and just put the chip back in.

After 3/4 of them were replaced in sockets I asked the owner if he wanted me to socket the remaining chips and he said yes so I did. So this Space Invaders has all the chips in sockets now hehe!

I ended up burning up an LED once. My friend loved messing with electronics and he gave me a single LED to fool around with (we were in like 1st or 2nd grade at the time) and I made the extremely dumb decision of trying to connect the LED to a 9v battery. Of course, this was way beyond its voltage limit and it lit up briefly then my room smelt highly of melting plastic (a smell I now associate with danger). It didn’t work ever again surprisingly. Hate when electronics burn up. It happens though. Always cool to see another pinball repair video. I love electronics (and now know not to burn them). Cool video!

You are wrong if the chip has an internal short yes it will smoke. If the pull up resistor has changed values, the resistor will smoke, not the jet.

If it was plugged into 240VAC while setup for 120VAC the transformer would most likely have gone up in smoke. So unless there are signs of transformer damage or a transformer replacement it's unlikely that happened.

I was more of a video game guy, but there was a big splash about this game because it had so much digital "boost". There was talk of video games killing pinball, but the same magic that created the video games was also boosting the pinball industry into "modern times", and Black Knight was leading the charge with all the digital trickery with lighting, magna-save, multi-ball play, voice, etc, that made it a pretty exciting game. It's one of the few pinball games I really got into (Star Trek:TNG was the other).

Funny how these old boards have no input protection… no optoisolators, no shunt diodes. They’re just vulnerable to whatever comes into the chip from off the board. That 47K/4.7K? pull-up resistor would never be hurt by being shorted 5V to ground. In fact, it’s shorted every time you close the switch on the door. Resistors never short (except wirewound), they burn and open when too much current passes through them.
@LyonsArcade
3 жыл бұрын
The whole point of what I was saying is that they didn't send 5 volts to the resistor they sent the solenoid voltage to it, 50 volts or whatever it was when they reversed the plugs.... So it then had 5 volts on one side and 50 on the other side, I was just checking to see if that damaged anything but i'll take your word for it I shouldn't have checked it because it never would have been hurt

I like how you teach. Most people in electronics repair videos want you to go to electronics school and learn all the technical stuff first before you can understand what they are telling you. The way you teach will give novices the boost they need to get them interested in trying to repair stuff on their own. I see this as a good thing. Electronics can be so overwhelming that most potential future repair men or women will give up way too early. Yes a person should learn the basic terminology so they have a basic understanding of electronics and how things work. No a person doesn’t have to have a 4 year college course to repair a pcb.

I hate the elitist attitude a lot of techs have, even worse a lot of times they won't work on things they feel are beneath them, I think if somebody's willing to work on something that's a good thing even if they make mistakes and don't know what they're doing. Most of the repair is just slowly thinking about what the problem logically is, and working through it the best you can step by step. Thank you for watching Bill!

I definitely did the black/white connector swap right after setting up my Gorgar. That was a difficult lesson to learn right out of the gate. Luckily not too much got fried, but I still had to do a lot of board work diagnosing the issues it created. Even worse was this was a "broken" game which I got for a good deal, so who knows how bad it was even before I swapped the connectors.
