Hey everyone. I know it has been awhile, but I've been taking all the suggestions and continuing to work on it and have finally got it working and looking good! For starters, thanks a ton @YerpS3s for the Sharp Image referral. After taking everyone's guidance and troubleshooting as many things...

No apologies necessary @trashedcabs, definitely like the questions being thorough makes sure I don't miss something. I did test the the step down and it is output ~98V and the pass through was reading the same when the cabinet was plugged into the step-down. So I think that means the cabinet...

Here are the pictures of the cabinet PSU (top) and the step down converter (bottom) When I plug the cabinet into the step-down and then the monitor into the AC100V outlet on the PSU the monitor never turns on. When I plug the monitor directly into the step-down it turns on. However, when I...

The cabinet has a PSU that outputs 100V via a standard two prong plug. When I plug the monitor into that and turn on the cabinet the monitor doesn’t turn on. However, when I plug in the monitor to an external 100V PSU (my step-down converter) it powers on. The odd thing is when I then connect...

So even though I’m feeding it 100V through a step-down converter, turning 120V to 100V, it is going into protection? Sorry for the silly question, just trying to make sure I understand.

Alright new information. I kept using the multimeter and testing parts but everything checked out fine. So I threw the chassis back together and got it back in the cab... still no video no electron gun. However, in all my searching I came across a thread that mentioned plugging the monitor...

Alright so I ordered new HOT and @trashedcabs you were right I get a false negative on both HOTs in circuit and they both check fine out of circuit. So I don't think this is the issue at this point. I started going over the components on the board again and I found an odd capacitor in the power...

Some long overdo positive feedback for @sheep_nova. I bought a PGM Spectral vs. Generation cart from them last summer. While the cart had some issues, which I now know to be common with this complex PGM cart, they went above and beyond to help me with the issue. They helped with hardware...

I bought an RGH Xbox360 from @mattsoft and it arrived quickly, well packaged, and worked as expected. Great experience all around.

Alright I did that and when the HOT is out of circuit B > C reads .62 and B > E reads .656... so guess that means that HOT is fine? I'm curious does the false negative reading in circuit mean anything. Like does it help me to tract down when could be the issue? I ask because I tested resistors...

Thanks for the advice. I'll check those components as well. It is gonna take a few days for a new HOT to arrive so I have some time to verify the other components in the area.

Alright I think I solved the transistor issue and I think it is just a nonstandard leg layout, thus the HOT is fried. I found another BCE configured transistor on the board that I don't suspect has issues. I then used the multi meter to measure from B > C and then B > E and I got .784 at...

Yeah that is what I thought but on the PCB it looks to be clearly labeled B-left C-middle, and E-right. It is kinda throwing me off because I used to the CBE configuration. For what it is worth when I measure I put black on the middle and red on the left and right I get the same .482 reading...

Alright. Some progress... For starters I have determined the a Hitachi GMK-29FSN is not remotely the same as a GMK-29FS2. I order the parts based on the referenced post, and once they arrived I pulled the chassis and lo and behold they don't match up at all. Now this is my fault for not...
