Sanyo 20-EZV Mario Wide Body - Smoke? Vertical Collapse?

Hi guys,

I just picked up a widebody cab today that was sadly converted to double dragon. I will be converting it back to a MB.

I brought the machine home today opened it up and looked around, pretty clean on the inside, a little dusty, nothing too crazy.

I fire it up and I get:

This is the vertical collapse I always see people posting about correct? I could see the line across the screen flicker a bit when i put a credit in and moved the joystick, so I am guessing this is the case.

There was no audio and when checking the pots, i noticed that the Volume pot was broken from the board, so that will need to be replaced.

Also, when i first powered on the machine and i saw the line across the screen I went around back and my cousin said "something is smoking" I looked and it looked like some smoke was coming from the flyback and inverter board area. I unplugged the machine, nothing smelled like electrical components frying. I blew it out with a air compressor to try and get any dust off the board. I fired it back up and nothing was smoking this time, and I still have the line across the screen.

Could the smoke have been dust burning off the thing since it hasnt been powered on in months?

I shall begin following the flow chart for this monitor if this is the vertical collapse. Bob roberts is the guy who sells the cap kits and transistors I will need to replace correct?

Thanks,
Chad
 
check theses

install a cap kit first and go from there

also check TR402 TR403 and if i recall correctly check for a broken trace between R423 and D401 some time you need to install a jumper. cause the pads get damaged.

Peace

So I am guessing this is a EZV montior because the metal around the flyback says EZV on it in the lower corner:

Are the cap kits for EZV and EZ the same?
 
Thanks Buffet.

I just ordered the transistors, caps and pot replacements from Bob Roberts. Hopefully I'll get this monitor working, then I'll be searching for a mario bros board set
 
hope i comes back to life

cool let me know the results.

i fixed a couple that were like that. a cap kit and a couple broke traces and they were good to go

and if you need help come on by the house and we will see what we can do.

and i may have a spare mario PCB i will have to look.

Peace
Buffett
 
Only thing about the EZ..all the damn caps. LOL Its like doing 2-3 G07s. Take your time and double check values and polarity.. patience is your friend..if you get frustrated or tired walk away and take a break. Good Luck!

If that is a double dragon I would think that is not a sanyo monitor in that cab. Unless whoever converted it to a Double Dragon put a video inverter board in it. Did you open the can and look at the monitor?

It's a sayno ezv. It's got the inverter board on top of the flyback cage. It's a Mario widebody someone destroyed. It's wired to a jamma. I will be restoring it back to dedicated MB.

Sorry. They changed the sizes I can upload from my phone :(

Cool, I might have to do that. It will be much easier, especially since you have fixed these before... I broke one last time I tried, and sold it to you after I fucked up... Is this your attempt to break my sanyo and keep it for yourself??? :p haha

PM sent!
 
Awesome to see you are already cracking into her and getting progress made in no time! I never powered it up ever, But assumed a cap kit and touching up some solder joints would do the job. I capped the sanyo 20ez in my playchoice about a year ago and it was only the third cap kit i ever did. First was a G07, and then a WG4600, and it went like a breeze.

If i had to give any advice i would recommend pulling the entire monitor out, and then taking the chassis off. The hardest part for me was removing the chassis while it was still in the cab. I'm not sure if it is mounted the same way in this mario WB, but in the pc10 it was off to the side and was a Bi*ch to get out for sure. Anyways good luck bro, i really look forward to watching the progress here and to see what i could have had lol.

oh btw, i got a good laugh when you said it was dusty inside, i had vacuumed it out a few months ago when i first got it, and MAN it was like 1000 times dirtier than it was when u got her lol.

Good luck man
 
yea i can help you break this on to get a cheap monitor no prob:D

but yea lets do it rite the first time. so that the rest of it you can do at home. in your spare time.:)

With some guidance from Buffett and his kick ass desoldering station, the monitor lives!!!!!

Replaced all chasis caps including filter cap, tr402 and tr403. B+ pot and sub brightness pot.

All caps on audio board and the two tranisistors.

Replaced volume and brightness pots on remote board as they were busted.

Also reflowed the section around the flyback and the transistors and resistors on the neck board.

Tested the machine with a DK jr. Set b+ to 108.

The picture was upside down, but it's oriented for horizontal in the MB WB so im not worried about that.

Thanks again Buffett!
 
no prob glad to help

no sweat any time.

glad you had a good time.

we beat that monitor into submission.

Peace
