mfc2mil Posted July 22, 2015 Share Posted July 22, 2015 Hello I recently acquired a Overkal (Spanish clone of the Magnavox Odyssey), and have been tested in 3 TVs (one TV Thomson 21DC320 a Sony Trinitron 14 "and Thomson television early 80s), but the screen is completely black, is not the "square" representing the players, or the network nor the ball. The Overkal've opened and I saw that the motherboard is in good condition (no burned parts or dirt or anything), the only thing worse is the battery connectors, which are quite rusty. I've been adjusting various knobs there on the motherboard, but he has not served. I wonder what component fails, if the signal type you use and my TVs are not able to support ... PS: I have connected Overkal on batteries as a power transformer Atari 2600, and also shows exactly the same. Sorry for my bad English, I used Google Translate to translate. Thank You.

CatPix Posted July 27, 2015 Share Posted July 27, 2015 Have you tuned your TVs on all frequency? Try on all bands (VHF I, VHF III and UHF). It's better to use your oldest TV and to a manual search if the TV allow it. Quote Link to comment Share on other sites More sharing options...
