Another saved from the dead pile! I'll be using that case tab image to fix one of my machines! Thanks zzj!

The windings on the flyback/ hv transformer short internally. The short causes heat that can melt the housing as well as the expansion of gasses. It can either crack or burn a hole through the plastic housing. They're usually toast at this point.

You could try some high voltage putty or carona dope, but it's a band aid if it works. The hole was most likely caused by a short and you're going to have to find another hv transformer. If you can't source an nos/pulled one your best/cheapest bet is to find a non working monitor and hope the...

I've had to lubricate the bearings on a number of seagate drives. I would, however, recommend backing up your drive. Especially since you opened it. You can use a modern scsi drive replacement solution ( zuluscsi or bluescsi) in initiator mode to copy/backup the drive to an SD card. That way...

As croissantking said, your sound issue might be something as simple as a dirty audio jack. I would cover all the simple stuff first and trace your way back. Looking at your pics, another issue I see is that some of your caps aren't soldered to the pads. Are you using enough flux? Make sure...

Nice. Congrats!

Dead mac scrolls was written before all these caps went bad. That's a common issue with monitors, and it's usually caused by a bad cap. When was it last capped?

And so, the battle begins... This beast has parts... LOTS of parts.

Yeah... I was just about to say the same. Se tubes run at a super low bias on g1 from what I've seen in the past (-36, I believe). I was using a sencore cr3000 to check out a bunch of tubes and had lots of fun figuring out their settings / pinouts (the pinouts I found in references were...

When you say your doner tubes are kinda compatible how far off is your heater voltage? I believe the se heater voltage is 12v (which threw me at first since most run around 6.3v). If your heater voltages dont match, you oght be having issues with the gun emmisions.. Also, just to confirm...

Not sure its worth all the work, but you could design a transposer to change the orientation/position of the aforementioned upgrade - i.e. socket booster (see pic). Not exactly this... I'm just using the picture to convey the thought process., i'd design something like it to change the socket...

Yeah...I've never seen anything like it before. I haven't had a chance to boot it yet (wanted to go through p/s before power up). Wanted to see if anyone had any insight into it first. The joystick and buttons just go through the 16 pin dip gameport, so they should work fine. I believe the...

I was given this Frankenstein this weekend, and can't seem to find anything on it. It seems to be something made videx. Its a strange beast. Besides the obvious controls on the cover, It also has some other weird stuff inside. It has a videx 40/80 column card in it (not weird), but it has an...

That looks an awful lot like a molex micro fit connector. This might not be the exact one, but will get you in the ball park. https://www.molex.com/en-us/products/part-detail/436450400

I've had tons of problems with iisi power supplies, so i'd tend to agree too. If you have an iici (or model with the same power supple) its plug and play to test with. It's obviously heat related since you're getting 4 mins cold. If it ends up not being the power supply I'd get you a can of cold...

Same here... I've seen people drag solder them, but I like to go one pin at a time. To quote Hicks, "Its's the only way to be sure". I use the same size chisel tip, and switch out with a bent conical tip for pads that need a little more heat. For sure! You need to know if there is any...

It would be dangerous for me to be that close to Jameco! Definetly jealous. There are very few places to even drive to get parts nowadays. Luckily, Mouser is normally next day delivery. Great troubleshooting!

It's a great feeling to finally get that project your working on finished! Congrats! Sounds like you had fun with the wireless!!! I went hard wired, so I never had to address these issues (luckily!). Good info for people wanting to do the same in the future! Only thing left I want to do to...
