demon_fish93 Posted November 9, 2014 Share Posted November 9, 2014 Hi everyone, just registered. Recently I installed the av mod here: www.vintagegamingandmore.com/pal/ to my 7800 and now it doesnt power on, I noticed when I press the power button that the black chip on the top right of the console gets very hot and gives off a burning smell. Ive installed this same kit on my 2600 junior with no worries. I followed the 7800 tutorial correctly. Hopefully someone can help. Quote Link to comment Share on other sites More sharing options...
Rybags Posted November 9, 2014 Share Posted November 9, 2014 There's various revisions of the 7800 so you need instructions that relate to your one. Black chip @ top right? The vertical component at top right is a voltage regulator, it gets hot normally, that's why it's screwed to the metal backplate which serves as a heatsink.

Osgeld Posted November 9, 2014 Share Posted November 9, 2014 (edited) the voltage regulator will get kind of sort of hot anyway, but very hot and burning smell, you shorted something to ground, check your wiring, expect to get a new regulator as well Edited November 9, 2014 by Osgeld Quote Link to comment Share on other sites More sharing options...
