RGB Video Input Hack is a Master Hack for CRT Televisions

component-video-input-hackYou know those hacks that you see, and you totally understand them but are dumbfounded by how the person got there? This. This is the definition of that.

What’s shown on the screen above is about half-way through the process of hacking RGB video into a CRT television that’s not supposed to have it. The lettering is acting a bit like a layer mask, showing bits of the Super Mario Bros. start screen which is being injected from an original Famicom. [Michael J. Moffitt] figured out that he could patch his signals into the multiplexer which is responsible for overlaying the TV’s menu system. Obviously you can’t get your Mario on with this view, but the next step was as simple as finding the blanking pin and tying it 5V. Brilliant.

This particular hack is worthy of recognition. But read through [Michael's] write up and it’s obvious that he knows the driver circuitry beyond the realm of normal curiosity. If you ever get stuck while trying to do something custom, we’d recommend pinging him with your questions (sorry [Michael] but with great knowledge comes great responsibility).

 

Built-in hex editor unlocks plasma TV features

[Nick] tipped us off about a guide to unlock extra features on Panasonic televisions. The hack works on the G10 models of plasma TVs and uses the service menu to gain access to the EEPROM memory. With a few quick steps you can change some data with a built in hex editor, unlocking several new settings menus, or bricking your entertainment centerpiece. We’ve seen some Samsung TV hacking in the past and hope that with increased processing power in today’s models we’ll someday see consumer TVs available with open-source firmware so that we can integrate of our favorite entertainment software.
