Problems with Frogger (thread breakup)

[themonk3y]

Frogger: I don't know where to begin with Frogger. I can never recall this machine ever actually working, but we got it in a lot and the price was right so we took it. I was able to get the monitor to actually show something today, even though that thing was only the color white. Any suggestions what I should be looking at?

The machine


The nothing


Not really sure what to do here. It was recommended I check voltages so I'm going to do that, I just don't know where

For starters it looks like you turned up the brightness or HV too much up on the monitor.

See if there are any test-points on the Frogger PCB that indicate +5V, +12V etc. Check the voltage between those pins and a GND pin.

[themonk3y]

Haven't found any test points. But when I unmounted the board I noticed some leads under neath the board. That's usually not a good sign right?

Well in my father's almighty wisdom, he went and looked at the machine today. I was messing around with the tube because there were some  components on the board that looked funky. I heard a hissing noise from across the basement, uttered obscenities and the like. Sure enough he cracked the picture tube taking the anode cap off. I asked him if he discharged it first and he said no.

I'm utterly pissed right now. This man had 25 years of ET work behind him and for some stupid reason he chose not to discharge the tube. Ugh, so now I have no way of knowing what is wrong with this machine. A new tube would cost me $100 and I don't have that kind of money to throw away on a single piece of a machine right now.

It figures that the one person who knows something about these machines, or at least circuitry and the like is the one who messes things up and not me. Alright, I'm done now. I don't even want to have him help me pull the CRT from DK to do the cap kit now. FFFFFFFFFFFFFFFFFFUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU.....

rage?


Go to a pawnshop and buy a cheap 19 inch TV and do a tube swap! http://www.arcadetreasure.com/monitorinfo/Monitortubeswap.htm

Ive used this tutorial a couple times with excellent results

Hm... in that case back to the basement. We might actually have a TV like that somewhere down there. The equipment from his old VCR/TV repair business just piled up and it was never disposed of. I didn't think it would be that easy. It seems like there would be more to it.

[Mauzy]

If you need any help, let me know. Just make sure you pay attention to what you're doing and make sure to mark purity rings and and stuff like that. Slow and steady wins the race.

Discharging the tube doesn't have anything to do with cracking the neck.  He must have whacked it.

[themonk3y]

Thinking on it now, when he was taking the anode cap of he probably got zapped, spazzed out (like anyone would) and hit the neck. Either way, the neck is busted. Luckily the neckboard is still intact. Now to locate an old tv. We have an old magnovox but I think its a 25" so that won't work. Looks like I'll be checking out the thrift stores soon.
