I recently purchased a Coleco Telstar Arcade. Unfortunately it does not produce any video signal other than static. . The proper sounds for each game can be heard emitting from the internal speaker when the device is turned on. I opened the case and confirmed that all three coaxial connections were in place. I didn't observe any broken solder points or components showing obvious damage.
Has anyone else experienced a similar problem and is there a solution? Any and all assistance is, of coarse, much appreciated.
