Shortasswattsy Posted March 23, 2021 Share Posted March 23, 2021 Hi all, Would welcome some help if I'm posting in the right place. I purchased a vectrex from eBay with no picture but had sound. I'm not really tech savvy but tested the voltages across the on/off switch and realised one line had no continuity, so I used some circuit cleaner to clean the switch and now I have a picture when I turn it on with sound. It can take several attempts of turning on and off before I get that humming sound and a picture appears, I presume it needs to warm up? If I do get a picture it rarely stys on and flashes off with what looks like a streak of lightning across the screen. If it does stay on it gets to the player select screen and then flashes and resets once I hit a controller button. I have some experience with soldering and recapping in game gears and other consoles but no experience on such a dated system. Any help, advice or a point in the right direction would be greatly appreciated as I havnt been able to come across this specific problem in my research. Thanks all!

sprazzi Posted April 9, 2021 Share Posted April 9, 2021 (edited) Did you happen to read through this topic?: First thing I had it fully recapped Then we found out that I had a dead diode in my unit which was cutting the power off... after replacing it everything returned back to operational state. Cheers and good luck! Edited April 9, 2021 by sprazzi wrong link Quote Link to comment Share on other sites More sharing options...
