    Beautiful! I have a question. I didn't realize there was a 4700c. I was thinking about buying the 4700sx, but then I also saw a 4700ct. The main reason I am looking at the first two is of course the orange gas plasma display. I couldn't find much about the CT. Do you happen to know if it has the orange gas plasma display? Thanks for reading this.

    Mine after greasing up the motor on the CD mech works, but strangely when powered on spins anticlockwise and takes about 5 mins to warm up before it wil read a disc (spinning it the correct way, clockwise). Caps seem ok on visual inspection. any ideas why it needs to "warm up" and why the motor spins anticlockwise slowly when powered on by not reading a disc?

    Excellent video. I have two of these machines. One of them fixed up for now (recapped systemboard, inverter and remaining screen caps + cf/ide 512mb CF). The other one is still to be fxed (as soon as you connect it to power, it will power on regardless of how the power-switch is on or off). They are quite nice machines. Not the fastest ones around, but otherwise quite cool.

    Hello. That is a great modification, one that should have been done from factory. Please execuse my lack of knowledge. I'm trying to have the nVidia Shield TV (same as the one in this video) as the main headunit in my car. I have a broken Shield power brick, so I bought a 12v to 19v 3amp buck converter. I snipped the wire from the power brick, connected it to the output of the buck converter and plugged it in. The nVidia logo showed up and my happiness was short lived. As the screen turned off. Any ideas what could I be doing wrong? I measured the output of the buck converter to be 19.16v Appreciate any help.

    I can indeed, but it's a lot more visible on camera than it actually is in person, and for a cheap repair I'm not that fussed. Before you couldn't open the screen more than a few cm before the backlight switched off entirely, so this is very much a cost effective win in my books :)

    Great job! But I'm surprised that you insert ali-chips without testing them first. For me it's always the assumption that not only they are fake, but also not working. So I always follow the rule "check first, insert later". Saves a lot of time. I'm planning to build a self-designed 5160 replica, together with a replica of CGA videocard and replica of adlib, and I can already see that fake chips are going to be a problem.
